How to do if the car key lost in the car?

We buy the vehicle, the vehicle's own original keys generally not less than two, as a common key, another commonly known as the spare keys. We suggest that the spare keys should be placed in the home is a safe place, don't try to take on the body in order to avoid the loss caused by unnecessary trouble. When the used key is locked in the car, possible to retrieve the spare key, this is the most simple and minimal loss.

If the body in the field or far from home, take the key is not too realistic, select unlock, lock is also a way to help. Certainly must choose the lock company formal qualification, according to different models, the general cost of 200 yuan -500 yuan interval, the individual models will be more expensive. The lock time according to the different models uneven, almost a quarter of an hour or so to complete.

Any spare parts for car lock company to unlock does not need to destroy vehicles they will lock from the joint vehicle glass or door with special parts. The lock does not destroy the door, so you don't have time to replace the car door lock.

If you are unhappy in a wilderness locked my keys in the car, take the key and the lock is not too realistic circumstances, only to break glass this method, but also pay attention to hit the glass. In order to minimize the loss, we must first understand the whole car which piece of glass is the cheapest, don't even glass smashing up easily hit piece, you should at least know the windshield or skylight price must be at least 500 yuan, and the door on the triangular window may be as long as 100 yuan.

The back door of the door closer to the triangular window door, so if you really need to hit the glass door, had better choose the. Of course, if there is damage to other glass you, just to replace the word, also can hit the block to change the glass, and perhaps also by the insurance claim.

Another tool of choice is also important, the most insurance is the use of safety, good effect risk small, if not equipped with his car, can find nearby bus or bus to borrow. Cannot but not to try not to choose bricks instrumentation, slightly improper will scratch yourself. The damage to the glass should be as soon as possible to repair, if repair place far distance to be driving a distance, we suggest the injury part do temporary "bandage" tape.

Different vehicles out of different considerations in the design stage, there are different locks, suggest you to understand clearly, such as whether to automatically locked within a certain period of time, or after locking the vehicle alone and open or close a door is unlocked and other details, as far as possible to avoid embarrassing situation key lock the car. Good maintenance play an important role in car,some car tools as Digiprog 3 and Creader VIII are necessary.

Vehicle filter introduction

Engine oil filter function is to filter out harmful impurities from the oil sump oil, to clean the oil supply crankshaft, connecting rod, cam shaft, turbocharger, piston ring, the lubrication, cooling, cleaning effect, prolong the life span of these parts. Oil filter function is to filter out impurities, so be replaced together with the engine oil. If you don't change them, oil not filtering can lead to internal parts of engines due to impurities in the oil accelerated wear.

Oil filter should be qualified with strong filtering capability, small flow resistance, high temperature resistance, long service life and other properties, and the disadvantage is not resistant to high temperature, poor sealing performance, the paper filter element easily damaged, it will affect the oil filtering effect, while the engine overhaul.

The air filter is a device used for air purification. The air in the dust, sand and various impurities if directly into the engine cylinder combustion, they will accelerate the abrasion of the engine, thereby reducing the serious damage to the service life of the engine and even cause engine.

Air filter is divided into two kinds of dry and wet, the dry is the most commonly used car models, its material as filter paper or non-woven fabric. In order to increase the air through the filter area, mostly produce many small fold. When the filter mild fouling, can use compressed air blowing, when the filter fouling serious when the replacement of the new core shall timely. In general, the air cleaner and no replacement time accurately, which is based on the vehicle using the environment to determine the replacement time, but no longer than 1 years, the vehicle traveling distance less than 15000 kilometers.

The air cleaner in the general location of the car behind the front air grille, you can check the air filter in ordinary car, if it is found that the dirty words can be taken out to clean or replace.

If serious blocking filter, will make the air resistance increases, the engine power decline. At the same time, because of the air resistance increases, also can let the driving computer judgment increased petrol in proportion, causing the mixture too thick, so that the engine operation state variation, increase fuel consumption, but also easy to produce coke.

Qualified air filter can ensure that the engine work is the intake air quantity needed, and can filter out the foreign body in the air, while the poor quality of the filter due to the quality of the use of materials is poor intake will lead to excessive or too small, or even not to the filtering effect, directly to the foreign body in the environment to make the engine cause serious engine wear.

In addition, poor air filter service life is very low, the general use of hundreds of kilometers will be dirty and poor filter will make the air resistance increases, the engine power decline. Or increase fuel consumption, and is easy to produce coke. Cars make our life more and more convenient.With the development of the city, more and more people own a car, and you can find other related car tools like Launch X431 IV and T300 Key Programmer to do better.

Traffic signal identification of common

The ground marking role is to inform the driver of road traffic regulations, bans, restrictions, drivers and pedestrians are required to strictly comply with the marking instructions. Solid white lines used to distinguish between the different lanes in the same direction, that is to say everyone is a direction of traffic, pay attention to! When driving across the white solid line can not be. The solid yellow lines used to distinguish the different direction of the lane, in general the painting in the middle of the road, like a belt, the road is divided into two directions. As noted here, regardless of the single yellow line or double yellow line, as long as it is solid, in general it is strictly prohibited and span, such as overtaking, turn, turn, is not possible.

The yellow line's role is to distinguish the different direction of the lane, but regardless of the single yellow line or double yellow line, as long as it is dotted, can the overtaking or turn around in safe conditions. The yellow dotted line will appear in the narrow road, such as the mountain of the two-way two lane will draw the line, the distinction between different direction at the same time also allows overtaking other vehicles may use. The dotted line in which one side, the side of the vehicle can be temporary and bounds since then, such as overtaking, turn and turn; solid line is not allowed to lend to overtake.

No access sign, suggesting that the vehicles and pedestrians can not move forward and through, in order to avoid traffic accidents. The red circle blank is banning all vehicles, there is a white bar is no motor vehicles, there is also a red circle with a white cross on red circle, different patterns can indicate different meanings, suggesting that people can't forbid the direction of travel.

Common stop sign has two kinds: the first kind is no parking and long time parking signs, as the red circle with a red cross. This sign has two kinds: the red circle with "the road", indicating the road stop; no "road", refers to the road stop. The second category is prohibited long time parking signs, as the red circle red slashes, show that the section can be temporary parking, but no stop for a long time, if the parking must guarantee the car driver.

To mark is divided into two kinds, one is the stop line; a deceleration lane. Parking lane identification for the octagonal middle "stop", meaning is at the intersection of wait-and-see again travel stop at the stop line. Said the vehicle must be at the stop line parking lookout, to confirm the safety, was allowed to pass. Deceleration lane, that the vehicle deceleration lane, the driver should slow, observe the road traffic situation, to allow vehicles to roads. This representation for the inverted triangle with "let" word.

Under normal circumstances, the right is not affected by the signal light control, but in some large traffic volume roads, in order to avoid the influence of lateral right turn vehicle traffic and cause traffic jams, right also is provided with a signal lamp. From the current actual situation, in addition to the red light can not turn to the right, green or yellow light flashing, can turn right. Although not so much, but we also need to pay special attention to the daily driving.You also can find some hot car tools like Digiprog III and Autel Maxidas DS708 to help you solve the car problems.

How to choose the license plate frame reasonably?

Remove rust material products. License plate frame is not itself belongs to consumables, one with many friends to buy a car, only an estimated to sell a car will be removed. So long time, license plate frame number is also a part of the appearance of the body, with a year on the rust will make people mad.

Try to choose the aluminum products, aluminum alloy material that is far easier than stainless steel to judge, for example see section and OK weight can be distinguished, of course, the price will not be too cheap. And so to say, if the use of cheap stamping steel sheet and after plating products, new time is really difficult to distinguish, the low cost of products low prices, but is often the most easy to rust, some 4S gift customized products is this.

Try to choose a drawing or frosted "plate" license plate frame. Whether the license plate frame the network or the Auto Parts City buy, most are some text, pattern and other contents in the above printing. As for the young fashion owners, a license plate frame is personalized, if the 4S store a license plate frame, it is their shop in 99.99% ad. Feel shy, but judging from the law angle, the license plate frame are illegal, license plate frame no marks, letters and decorative pattern.

Secondly, license plate frame color is not limited, but in the pattern processing, editing and suggest that you try not to choose the mirror polished product, but instead of drawing or frosted pattern. The reason is very simple, the sun and the car lights will be the license plate frame reflection, the reflected light easily affect vehicle after the driver's line of sight.

Many social vehicles on the road, of which about 4-5 installed the license plate frame, and in the installation of the license plate frame in the vehicle, about 90% more than the use of the old version for license plate frame. From the picture we can see, the old version of license plate frame frame is wide, of which the bottom border almost to the pressure of the license plate numbers and letters, could not meet the new standards more than 5mm. But before some provinces and cities focused enforcement actions, law enforcement personnel to judge whether the violation of license plate installed on the basis of even whether exposed white border around the license plate.

Then according to the above, we find that the license plate frame these "new rules" version has been done the corresponding design, such as the almost uniform no decorative patterns of letters, for instance to complete the plate completely exposed on the outside, white edge. Of course, in contrast, license plate frame the new version of the price is higher.

Prohibited the purchase detachable vehicle license plate frame with lock. In addition to interlocking detachable plate, more of a remote automatic covering or flop products, this kind of product is more has been authorities banned, if be investigated and dealt with may be subject to heavy fines, penalties and buckle car such as the severe punishment.

Some useful driving tips can help novice drivers driving safety

First of all, the weather condition is must pay attention to before going out, novice drivers on the road most don't know the way, the road before planning your trip, have a look which way, which road car less, pre planned a suitable route. Have a look first to their car in front of the car, around the car a week to check the vehicle has no abnormal. Have a look whether pneumatic tires, look at your license has not been mud or other things occlusion, if you are driving at night need light to check your Is it right? Can open. If these problems exist, will cause unnecessary trouble in driving on the way.

Found a loss of pressure is probably your tires were Norte, if left untreated or were not observed in the running, easy burst accidents caused. Vehicle license plate must look, don't be slurry or plastic bags and other dirt occlusion, we strongly condemn the act of intentionally block the plate. To check a night light road before, if it is found that the lights do not light must view the reason, if you cannot repair, it is recommended not to drive. After these basic inspection can get on the bus.

The car to have a look seat and mirror is not adjusted, to avoid the start driving after the re adjustment, this will let the driver distraction, which caused some accidents. When the seat is adjusted, the first step is to adjust the seat, the backrest angle of sight, not too low, at the same time, to the head set aside some space, so as to avoid the vehicle bumping head hit the roof.

Next is the before and after adjusting the seat distance. Step on the brake pedal as adjustment with standard, depress the brake pedal, if the right leg is fully extended, this is not rapid, effective steps on the brake pedal in an emergency situation, one can imagine the consequences. If the right leg to keep bending, also won't because of bending and uncomfortable, so the seat front distance is more appropriate.

The rear-view mirror is unfolded, can be observed from the mirror in his body, and the body area of not more than 1/4 is a reasonable range image. Then the mirror adjustment level, in principle to observe the car from the side mirrors in the scene, the distance in the image plane center can. But some friends used to be the right rear-view mirror angled down, in order to facilitate the observation of the right road in reverse, this approach is not wrong, just not too low to the horizon angle, as the benchmark, road area not exceeding 2/3 surface area is the reasonable range.

The interior rear-view mirror adjustment will be relatively easy, keep a correct sitting posture, the rear window mapping, the rear-view mirror, and keep the inside rear-view mirror horizon mirror can be maintained in the central. If your vehicle steering wheel also can regulate the before and after, you can adjust the seat back this step to adjust the steering wheel back distance, in order to achieve the best, most secure, most comfortable driving posture.

Putting brakes on China's auto industry

Another big name joined PSA Peugeot Citroen, Honda, Nissan, Kia and Volvo as a Dongfeng Motor Corporation partner last week, when French automaker Renault signed on the dotted line.

Renault sealed a 1.3 billion U.S. dollar 50-50 joint venture agreement with China's second largest automaker on Dec. 16. This allows Renault to assemble vehicles in China and provides easy access to the world's biggest auto market.

Foreign automakers must have a local partner to make cars in China. The policy was conceived in the hope that Chinese carmakers would absorb foreign technology and management expertise. After three decades, foreign brands dominate the market and Chinese brands are steadily losing ground and the rationale behind the joint-venture policy has come into question.

Foreign passenger cars took 73 percent of the market share from January to October, a small rise of only 0.4 percent from the same period of the previous year, according to the China Association of Automobile Manufacturers (CAAM).

As a late starter, China benefited from joint ventures and enormous profits were made from the sale of foreign branded cars but, according to Jia Xinguang of China Automotive Industry Consulting and Development, that's just half the story.

Zhong Shi, an independent auto analyst, holds the view that joint ventures hinder the development of local brands. If the government does not adjust or abandon the joint venture policy, the prospect for stronger local brands is gloomy, he said.

EASY MONEY, LAZY RESEARCH

Easy money and overdependence on foreign technology mean Chinese automakers have very little interest in research and development, said Jia.

Many Chinese brands use chassis technology and engines of foreign partners, sometimes even outdated technology.

First Automobile Works Group (FAW), the company that made the China's first truck in 1958, relies on foreign products, including the Audi 100, Lincoln Town Car and Toyota Crown Majesta, for the range of FAW vehicles sporting the Red Flag badge, a communist symbol.

FAW has joint ventures with Volkswagen, Toyota and Mazda. It sold 2.6 million automobiles and raked in 370 billion yuan (60 billion U.S. dollars) in 2011. It was ranked 197 on the 2011 Fortune Global 500.

FAW has no shortage of funds, but the National Audit Office revealed in June 2012 that the company had not invested enough in research and development of proprietary models and that its 2008-2010 profits stemmed largely from joint ventures.

Angry voices have been raised as Chinese automakers, in cahoots with their joint venture associates, launch so-called "self-developed" and "local brand" cars. These are nothing more than cut price, rebadged and relaunched versions of superannuated foreign models that have gone out of production.

Government assessment of state-owned automakers mainly focuses on profitability, which is detrimental to product development, said industry analyst Xu Binjin.

Private automakers do not get the same support from the government and it is an unequal struggle, competing with foreign and state-owned automakers, said Xu.

What is required is an adjustment to auto industry policy, cooling the cozy relations between state-owned and foreign automakers and obliging state carmakers to stand on their own feet, said Wang Xiaoguang of the National Development and Reform Commission.

PUT THE BRAKES ON JOINT VENTURES

The government encouraged auto joint ventures for 30 years and thereby stifled development of domestic brands, said Zhong Shi.

Rao Da, secretary-general of the China Passenger Car Association and son of the man who headed FAW in Mao's time, wants the government to suspend new auto joint ventures.

Whether China is an auto manufacturing giant lies not in the number of joint ventures or how many cars it sells. It depends on whether the domestic automakers have strong independent research and development capabilities, said Rao.

"How come we were able to design and manufacture the luxury Red Flag limousine in the 1950s but needed to import steering technology for mid-sized trucks in the 1980s?" he said.

He believes that using foreign technology discourages local technicians and that is why state-owned automakers have failed to stop the slide of their own brands.

The Ministry of Commerce told the media on Nov. 19 that the government may relax foreign investment restrictions in areas including auto manufacturing. This easing will weaken the position of indigenous carmakers further.

Dong Yang, CAAM secretary-general, said that if foreign ownership rules were relaxed, Chinese carmakers would lose control of joint ventures.

"Foreign ownership being capped at 50 percent is the red line we must not cross because we need to protect our Chinese brands," Dong said in his blog on the CAAM website in early December.

Although the foreign cars manufactured in China contribute to local taxes and employment, the profit distribution leans toward the foreign companies as they have advantages in technology and management, said Dong.

There is no doubt that joint ventures are an integral part of the Chinese auto industry, but local brands are the core interests, he said.

Foreign automakers' role in technological progress in China is different from their Chinese counterparts. Auto manufacturing is also concerned with China's economic safety and national defense security, he said.

Dong called for the government to solicit opinions from the auto industry and have a scientific appraisal before making a policy that will have a significant effect on the industry, he said. (Source: Xinhua)

Analysis of crash fire rescue

If the car is on fire, but the fire is generally not instantly burn to a great extent, unless the explosion. If it is found that the impact after the car has started smoking or open fires, which would give you more time and opportunity, if the car workers fled the vehicle in the first time, is possible to avoid burn cases. In addition if fled in the first time, if physical strength can support, rescue and opportunity for the fire can also control the vehicle, at the same time, the rescue to passers-by for help.

If in the event of a crash your car on fire, while the body and therefore appear misfortune burning, then immediately to do is to leave as soon as possible sources of ignition. Need to pay attention to every detail, is such a case the most likely to be stressed, out of control emotions may aggravate the damage, such as escape from constantly run wildly, as it will allow side airflow speed, will cause the body of the more serious, the exact opposite. Out of the fire in a safe place, then the reason will get better results.

If the body is burning with fire clothing, can be directly down on the floor, this is the fastest and most effective self-help methods; if the skin has been burned foaming, please do not blindly run or to blindly rolling when fleeing the scene, blistering skin will happen adhesion and the ground, can not solve the problem will be exacerbated, as much as possible to be able to get things break will be better.

This is a crucial issue, because the clothes are mostly cotton material or composite materials, it is flammable, so we will leave the body have already burning clothes as soon as possible, but not where it continued to hit has been burning clothes, clothes burned can buy, and damage the skin pain incomparable.

Here to remind a bit is, polyester and acrylic class fabric can become very terrible, in case of fire such as socks, especially silk stockings this thing, once ignited will very quickly burn up, resulting in a large area to promote the combustion, will eventually produce similar tar like substance, very sticky so, by hand is very difficult to pull off.
About how to break the window rescue in the car, like the life-saving hammer, window breaker such professional gadget, if there is no car articles conveniently can also rescue, such as fire extinguishers, headrest support. Through our experiments have shown that slot car glass into the bracket for the head pillow can be very effective to pry broken glass, of course premise is the vehicle head can be disassembled, and the vehicle can only removing headrest can not use other tools from saved.

Here the vehicle on fire extinguishers and closely related questions, if the fire has been unable to control, so we have to stay away from spontaneous combustion vehicles, then immediately dial 119, this is done in order to ensure the reducing loss as far as possible to its own security situation. Due to the limited capacity of the vehicle fire extinguisher, if the fire is big, you don't expect it can absolutely help you put the fire out, more than 3 minutes if you haven't found the fire control so you quickly evacuated to a safe place, cars burned on the burned, safety is the most important.

Is the external battery of recorder useful?

Is the external battery of recorder useful?
Some recorder built a small battery, can continue recording hours at a time out of the rear of the vehicle, many businesses will also be described as the function of parking guard mode etc.. But because the shooting angle is fixed, so the recorder has helped to determine the traffic accident occurred after running in responsibility, and there is no direct help for anti-theft simple parking later, so we think this some words are icing on the cake, there are of course better, even if not to also do not deliberately pursue.

Emergency saving function is a function of many recorder have after the accident, when a button is pressed, it will automatically save the video one minute before and after the keys, and the video will be stored in a folder, even if the storage card full record will not be the top off. But in our experience, this function is close, but once the accident, because few people seem to be the first time press this button, often three five minutes or even longer time, just the reaction come over, but it was too late. Some friends even press time will also worried that if not the situation.

Of course, part of a recorder will built a gravity sensing module, when the collision occurs through the induction to automatically save the video, than the relatively preserved function to ease some of the manual.So we think this may not be as important conditions of purchase recorder, this function is best, does not have this function also need not too care about. Also suggest that you travel more prepared stored on a card, in case of accidents can replace a new card to store, don't worry about the video of the accident may wash.

In order to win market recognition, many high-end vehicle traveling data recorder in meet the video recording function, a lot of new functions, such as navigation, electronic dog, lane departure suggest, even the gravity sensing and other advanced features, these high-end features can help product considerably, but for consumers, the purchase should first consider the basic video recording function meet, then according to choose another configuration requirements.

Typically, installation tachograph into paste and suction cup two, two ways are also very obvious advantages. Through our experience, the gluing mode more firmly, but the adhesive to way has drawbacks, unable to move, if needed in different vehicles for the use, I'm afraid not quite convenient.

Chuck is relatively flexible, convenient installation and disassembly, but chuck at high temperature in summer and low temperature in winter may have the risk of shedding, firmness and chuck is adhesive or slightly worse some.The installation method of recorder, general specification for a product will have detailed introduction, the installation requirements are basically the same. Space permitting, priority selection rear-view mirror rear position, here is located between vehicles, record the angle will be more accurate. Position not too close, otherwise easy to block the driver's line of sight.If the space is limited, to the right and left sides trimmer is also possible, but not the location too far, otherwise will not accurate shooting angle. Not even the convenience, the recorder installed in the windshield on the left or upper right corner, that is not of any significance.

Anti-rolling tires to experience the whole process of technology

At present, the passenger car tire almost all can do the anti prick treatment, the principle of this technique is to use the automatic NC spraying equipment MPN glue evenly coated on the inner wall of the tire, tire forming protective coating a layer of 3-5mm, when the diameter below 6mm in sharp objects piercing tire quickly when be MPN compound coating wrapped tightly without leakage; when the sharp objects are pulled out, perforation is MPN rubber coating instantly filled and sealed, effectively solve the vacuum tire stabbed rolling or discouraged trachoma caused and slow leakage phenomenon; similarly, MPN rubber coating can withstand the tread 10cm long wound without leakage. With every car 4 tires, a tire puncture preventing processing time required for 1.5-2 hours.

Give you about MPN glue, MPN glue is a semi-solid gel resin, high toughness, high polymerization degree, high peel strength, memory and self repairing characteristics, softening point temperature is 110 ℃, cold bending crack free, at -40 ℃ -110 ℃ temperature range can be maintained the performance of the same.

This experiment is very simple, we use the test vehicle for the anti prick treatment tire, directly on the test board and two blocks over, the two pieces of test board is a piece of 5 nails installed, and the other is a triangle plate installed, the two things in our daily the road on the way to the tire is a great threat.

Manufacturers technology full of confidence, said test can be reached 60km/h in the vehicle speed, but the site and the test board is too small, if the speed is too fast will roll up the test board to fly, not very safe, so we have to vehicle idling in the D block to pressure test board. After finished the test 1, test 2 and test completed in 1 hours, we have measured the tested tire pressure, and tire pressure does not have any change, are kept in the 2.85bar (do not represent the actual standard of car tire pressure).

Tire after the upgrade, four tire weight increase of about 6-8kg, fuel consumption is increased, but the show was not obvious, for many large cars, 6-8kg weight is negligible. We do the anti prick treatment is for the purpose of security, to increase the unsprung mass brings in performance or fuel consumption factors, in the car will not be reflected very direct.

Tire during the upgrade, MPN glue evenly coated on the inner wall of tire high speed rotation, the tire wall mirror like smooth, so after the upgrade of the auto balance and upgrade without much difference. MPN glue is semi solid rubber tire and tire, sprayed on the inner wall is very fit, does not affect the ehardness of the tire, in the running process can absorb the tire contact with the ground and produce vibration and noise, so after the upgrade the car noise can be reduced, the ride comfort can be improved.

Car air filter should always check

Spring in the north, sandstorm surprisingly high, in addition, the car high speed splashing of small stones and summer common bug liquid will bring harm to car paint. In addition, the acid rain ingredients with a strong corrosion function on the car paint, in the course of time will cause damage to the car paint, so in the rain more spring, change garments according to the maintenance of the car must not ignore waterproof work. In change garments according to the maintenance, it is best to give the car a paint beauty. More long more effective sealing glair is beauty, this will give the vehicle wearing an invisible protective coat.

According to introduction, sealing glair car paint brightness and hardness are improved, the car can take on an altogether new aspect. So the repair experts unanimously recommended the glazing, its effect is very obvious, can keep the car paint smooth, bright, but also to prevent acid rain erosion car paint.

It seldom owner window ventilated breathe freely, the car amassed a bacteria, the spring temperatures rise, coupled with the humid air, is all sorts of bacteria multiply growth season, so pay special attention to vehicle interior control work, let the car interior clean health, especially for car cushion, air outlet these health corner more to do cleaning work, keep the environment inside of dry clean.

Repair experts say, first of all, can give automobile "sauna", through the high temperature steam can remove the air vent, seats, interior equilateral side corner of the besmirch, also can remove the peculiar smell of the car. Then, the interior cleaning agent and then a dedicated for cleaning and disinfection of the console, door and other parts.

Repair experts remind owners, in their own for car interior cleaning, use neutral detergent to wash, do not use material cleaning, contains a strong acid. In addition, the cleaning to avoid audio, radio, CD and other electrical equipment and water from corrosion.

Nose in car air filter is equivalent to the human, is the first "levels" of air entering the engine to go through, its role is to filter out the air in the sand and some suspended particles, so that the air entering the engine is purer, so as to enable the engine to work normally. Spring air contains more dust, sand grains, the air filter is prone to jam, then the engine will appear not easy starting, idling instability symptoms such as weakness. General automotive air filter in the 20000 km to change a, 10000 km of the check, the spring is best in 2000 kilometers will check again, it is good for engine.

In addition, after a cold and snowy winter, chassis and tires detection cannot neglect. To thoroughly clean the chassis, to conduct a comprehensive inspection of automobile tires, especially for the four wheel drive SUV will have four wheel positioning, because its security work will directly affect the quality of vehicle and fuel economy.

Master some common sense about car is important,but you need to know how to choose car diagnostic tool like MB Star C3.

Tire maintenance can not be ignored

In the face of continuous high temperature weather, in some fans forum, discussion about summer tire pressure should be high or low is very fierce. Some owners think, summer high temperature, thermal expansion and contraction, the tire pressure must be higher than winter heating, easy to burst, so the tire pressure is low. And the owners think, if reduce tire pressure, tire friction with the ground increases exponentially, the tire temperature will rise sharply, tire become soft, sharp drop in strength. So, if the vehicle speed, can cause blowout. So, the summer can not only reduce the tire pressure, should also be adjusted upwards.

What is summer tire pressure high or low? Tire pressure is reduced, will bring two consequences, one is the tires, the tire will shorten the life of fuel consumption will increase two. However, to reduce the tire pressure will also reduce the risk of tire. The summer due to high temperatures, particularly travel at high speed, speed of 100~120 code, the tread temperature will reach 80 degrees, and even more than 100 ℃, increased internal pressure. As for the increase of tire pressure, the only use is to reduce fuel consumption. However, increasing the tire pressure in addition to may burst, but also bring a lot of adverse factors, such as the braking distance increases, the driving safety adverse. So, the summer should be low tire pressure.

In addition to high temperature in summer, and the rainy season, the tire in the rain in the past, the requirements of the tire is naturally increased. Therefore, the rainy season tire tread depth must not be less than 1.6 mm, preferably in more than 3 mm. Because the drainage capacity, decreased tread depth is too shallow, tire tire, causing wet grip drops, affect the safety of driving, especially the rear tire possible spin or drift phenomenon in turning.

When the outdoor temperature is high, the car park to the shade, the body temperature falls as well, don't be impatient with cold water and other means for the tire temperature. The best filling nitrogen in the tires, because the tire inside the gas itself is ordinary gas, because nitrogen is inert gas, and nitrogen is not easy to heat burst tire. If a tire, don't slam the brakes, but should be light "point" brake while the hands grip the steering wheel, try to make the vehicle to maintain a steady, parking and slowly pull.

Running on an uneven road, one must choose the road, reduce the tire and the road bumps, avoid mechanical damage and tire; two is decelerating, avoid tire bump and strong vibration. Muddy sections, should choose a solid, non slip through, so as not to tire subsidence, in situ idling, violent vibration caused by tire and tire side badly cut, scratch.

In addition, to select qualified tire and tire change regularly. A flat tire caused by many reasons, the tire performance deterioration is the arch-criminal. Tire even more durable, can not be a lifetime. When the tire wear, wire layer gradually fatigue, the tread of aging, will weaken the performance.
Besides,Car and car maintenance is a hot topic among young people.So,how to choose best car tools is also popular with people.Here recommend some like VAG Diagnostic Tool and GM Tech 2.

The basic common sense to extend the service life of engine valve mechanism

Gas distribution mechanism as an important part of the engine, the service life of the engine and whole life should be consistent, but in the use of often found in valve life is far below the whole life of engine, especially the valve, valve seat, valve guides and other major parts of short life, often in the two or three level maintenance, some parts have been more than limit the use and require early replacement, resulting in a tremendous waste of. This article on the superficial and prolong the service life of valve mechanism of.

The main reason, gas distribution mechanism of early damage
1.Repair of poor quality in the repair work is the problem of valve and valve seat surface machining quality is not up to the requirements, resulting in the work surface ablation, depression and early damage; camshaft bearing a scrape its clearance, contact area, each bearing concentric degree is not up to the requirements, the accelerated wear, the abnormal sound caused by early damage; valve guide in replacement parts, the reaming quality not up to the requirements, directly affect the service life of the valve and valve seat.
2.Repair data improper application: repair cannot scientifically choose the repair parts data are important reasons of early damage. If the valve and the valve seat contact width, provisions for 1~2.2mm inlet valve, exhaust valve for 1.5~2.5mm. But in the repair, people tend to think a bit wider than the narrow point of insurance, used to choose upper or close to the limit, the car valve face width and the newly repaired is approaching the limit. Another example of valve clearance, general motors for 0.2~0.25mm, but in the maintenance and adjustment also mistakenly believe that the gap is a bit bigger than a good point, therefore, the use of ultra limit. In fact, the gap is too large, not only reduces the power of the engine, but also the percussion sound (valve port since the early damage).

Matters needing attention in repair
Valve repair manual work in more technical differences due to maintenance personnel and cognitive bias , maintenance quality is difficult to meet the requirements ; therefore should be particularly emphasized in the maintenance of gas distribution sector service quality, and to take effective measures to improve the quality of maintenance to prolong its life.
1.Valve polishing: in repair operations, such as valve ablation, pits and depressions, all should be light grinding (serious when need replacing valve). Usually in the valve grinder, operations should pay attention to four issues: one is to ensure that the valve head and the rod of concentric, otherwise should first straightening; two is to grind the premise of complete cone as small as possible light grinding capacity; the three is to improve the surface finish; four is the valve end depression should be removed.
2.Valve seat reaming : valve seat reaming is usually manual labor , should pay special attention to three issues : First, eliminate depression , spots, could hinge on the basis of a complete cone , reaming amount as small as possible ; Second, even when forced to reaming , closing knife from the knife lighter , less hinge to observe in order to ensure reaming less volume and higher finish ; three are equipped with valve test to determine the location and width of a good face . Position should be adjusted to the lower part of the valve cone , partial or biased available under the upper and lower mouth reamer to adjust. Working width , the intake valve can be controlled by 0.9mm ( defined as 1 ~ 2.2mm), the exhaust valve can be controlled by 1.4mm ( defined as 1.5 ~ 2.5mm). Practice has proved that the width of the valve and valve seat grinding , the intake valve up to 1mm, the exhaust valve up to 1.5mm, were lower in the predetermined width , can greatly improve the service life.

The driver should make full test of the car before you going to a self driving tour

Car owners usually in the driving of vehicle tests include: startup, vehicles have abnormal sound; each lamp can work normally; brake system is normal; check the oil line. No leakage of oil, gasoline, oil pipelines are aging; wiper can work normally; check the tires have no crack, crack, tire pressure is appropriate; check the tires have no loose, spare tire can work normally; the car repair and maintenance machine professional structure do routine maintenance and inspection long before.

In these basic checks done, there are several critical examination can not be ignored. First, the engine prior to travel during the holiday must be cleaned in advance to carry out maintenance on the engine and check the engine oil, antifreeze usage insufficient to timely add, expired must be promptly replaced. Main engine maintenance cleaning lubrication system, fuel system, cooling system and other aspects.

Under normal circumstances, the vehicle every 5000-10000 km it for cleaning and maintenance time, in addition, in the face of engine noise is too large, accelerate the powerless, the water temperature is too high will also be cleaning and maintenance; two, gear box, in the long-distance travel, maintenance of gearbox is also very important. Automatic transmission in the car every 20000-25000 km, cleaning and maintenance time, or in case of transmission slip, high temperature shift delay, system leakage, cleaning and maintenance time. The removal of harmful sludge and varnish deposits, restore the gaskets and O ring elastic, make gearbox shift smoothly, improve the power output, automatic gearbox old oil replacement and; three, car steering system, general every 40000-45000 km when the vehicle steering system needs cleaning and maintenance time, or in case of difficult steering leakage, system, replacing the power steering machine accessories, also be cleaning and maintenance time.

Snow and ice days prepared anti-skid chain.The anti-skid chain type of market has anti-skid chain metal (steel mesh chain, steel ladder chain), TPU tendon anti-skid chains (TPU imported rubber mesh chain), advanced resin rubber anti-skid chain (special cloth), prices for different materials and different. According to the structure can make the anti-skid chain is divided into two kinds: one kind is already connected to the anti-skid chain hood shaped; another is cross installed several separate anti-skid chains, it is relatively simple and cheap, but less convenient installation. Especially need to remind owners, in order to avoid accidents, to buy time to pay attention to watch the product packaging logo, product manufacturers whether it have formal certification.

Anti-skid chains of iron bigger to tire damage, recommended for most car drivers choose is rubber or leather anti-skid chains, truck drivers choose anti-skid chain iron more. Due to the use of less frequency, experts suggest that private car owners to choose the kind of iron coated with rubber material has the antiskid chain cover type, the price is cheaper, at about one hundred yuan, can be repeatedly used for many times. The owners in the choice of the anti-skid chain, must first make sure your car is a front wheel drive and rear wheel drive, the tire chains must be installed in the play a major role.

Vehicle brakes should always maintain

Phenomenon: The car is moving, or continuous kicks foot brake, the brake pedal were riding in the end, brake suddenly failed.

Reason:

1.The total pump cup is broken or stepped over.
2.Brake pipe joints out of line or a serious rupture.
3.Pump cup is broken or stepped over.
Diagnosis: Hydraulic brake system to produce the reasons for poor performance of the brake, the brake pedal stroke generally, depress the brake pedal hard and soft feeling after the brake pedal when the brake pedal is increased stability and height to determine

1. When the brake pedal height generally too low, bad braking efficiency. Such as continuous feet or foot brake pedal height increased, and the braking efficiency improvement, the brake drum and the friction sheet gap or general pump piston and push rod is too large.

2. Maintain the braking pedal, if the height of slow or rapid decline, the rupture, the brake line somewhere joint sealing bad or pump the leather bowl sealing side, the return spring is too soft or broken, or the total pump leather, leather ring sealing side, the oil return valve and outlet valve is bad. The first step under the brake pedal, observe whether the brake fluid leakage. If the external normal, you should check the pump or pump failure.

3. Several foot brake pedal height, remains low, and in the second foot brake, feel general pump piston does not return, the brake pedal is a main pump push rod and the piston knock noise, is the total pump cup rupture or return spring is too soft.

4. Continuous brake pedal height kicks slightly increased, and a bomb sexy, indicating that the brake pipe penetrate the air.

5. Consecutive kicks, pedals were riding in the end, and felt no pedal reaction force, indicating that the master cylinder brake fluid reservoir chamber heavy losses.

6. Consecutive kicks brake pedal height is low and soft, is the total liquid storage chamber into the hole in the plug vent blockage.

7. A foot or both feet and brake pedal height, proper, but too hard bad braking efficiency. Gap should check the wheel friction film and the drum is too small. If the normal space, then check the drum wall and the situation of friction surface. Such as normal, then check the brake spring is excellent, general pump or pump cup is bloated, the piston and cylinder wall with is loose. Such as normal, it should then check the brake hose is not clear whether aging.

The car brake system maintenance strategy, security issues cannot be ignored

In addition to the safety awareness of drivers', the braking system working efficiency is the basic guarantee vehicle driving safety, influence factors and the most core. Now that the new regulations will these two topics emergency braking and rear lift to a new height, we also hope that we take this opportunity to examine their own car brake system, regular inspection and maintenance of the vehicle braking system is every driver should form the good habit of. But the fact that the braking system is not the engine maintenance so respected, even some people think that the automobile brake system is very durable, within a few years without inspection, misunderstanding of these ideas should be changed.

Due to the braking system maintenance oversight, some owners often wait until the brake system work abnormally to overhaul. This is likely due to the brake system failure due to brake failure, and even cause serious consequences. Therefore, only frequent brake system inspection and maintenance to ensure its normal work, thereby ensuring the driving safety.

Civil vehicle market mainstream at present, whether the disc brake and drum brake, its working principle is composed of brake friction pad and the brake disc and brake shoe and brake drum friction, the kinetic energy is converted into heat energy to achieve the braking effect. In the process of friction, braking system will produce wear, generally speaking, the wear of the brake system has a great relationship with vehicle load, road conditions and driving style, more is the use of frequent brake, brake system wears range is more bigger, also need more timely maintenance.

A lot of people will take braking system warning light in the instrument panel is light as the brake basis, but if we wait until we change is very dangerous. Because this sensor alarm system only part of senior car using direct induction of brake shoe thickness, while most civilian car alarm trigger is in the braking friction plate is almost completely polished, brake fluid level dropped, will enable the warning lights.Therefore, we suggest that in each routine maintenance is to check the brake pads are still have a margin, if the signs of wear, should be an early change to limit life bottom friction sheet, and don't believe the warning light.

If the brake fluid deficiency cause air to enter, the brake will become insensitive. We suggest a check brake fluid homeowners every month, pay attention to whether the brake fluid level decreased significantly, the quality is bad, if it should be timely to add or replace. In addition to long-distance running or in the off-road, and the stones or other obstructions may damage the brake fluid pipeline cause leakage, so every time after a long drive should also be timely to check the brake fluid condition, especially to observe is the chassis brake fluid omission phenomenon.

Brake fluid strong absorbent, if there is moisture in the brake fluid, in the process of braking friction produces high temperature will make the water vapor, gas in the brake fluid is compressed, it will cause the braking effect even failure. In the season of rainy season, the air humidity is big, some brake fluid absorption is serious, after wading, driving environment, also need to check, if the brake fluid has obvious deterioration phenomena, must be replaced as soon as possible.

ZF4HP22 ERRATIC OR NO UPSHIFTS

COMPLAINT: Harsh shifts into "D" and "R" and chattering of driveshaft when taking shift lever out of "D" or "R".Find car diagnostic tool for more?

CAUSE:
a. Coolant in transmission fluid.
b. Friction coefficient of friction disc LB3 and/or brake band B2 too high.
a. (See note) If coolant is detected in the transmission fluid, replace radiator and all friction linings in the automatic transmission.
b. For vehicles with transmission 722.4 already equipped with a brass radiator, or if no coolant can be detected in the transmission, install nitrated outer steel plates LB3 to resolve the complaint.

CORRECTION:
A leak in the transmission fluid cooler allows coolant to enter the automatic transmission.
This will change the friction coefficient of the friction linings in the transmission.

Therefore, the cooler was changed from aluminum to brass in the period between 2/86 and 6/86. These radiators are marked with a yellow paint dot next to the Behr name plate on top of the radiator. In addition, these radiators can be recognized by the brass-colored threaded connections for the transmission fluid hoses. These brass coolers are in order. The following tests to determine if coolant entered the transmission have to be performed only on vehicles with aluminum coolers.

Coolant in the transmission can be recognized by the following signs:
a. Transmission fluid has milky discoloration,
b. Transmission fluid foams heavily when drained,
c. The gasket on the large intermediate plate shows severe swelling or a green slimy coating (upper right arrow in Figure 1).
d. The intermediate plate shows signs of corrosion under the gasket (lower left arrow in Figure 1).
