According to experienced auto repair masters，Among the cars they have been repaired by them，The failure caused by poor engine maintenance accounts for more than 50%of the total fault。I have compiled several major ways of death for the engine today，Come and see if your gun is shot。Quickly rise knowledge，Be vigilant!

The car is in a strong spray state when the car is idling，That is to say，The car during idling，The valve is very small，The fuel injector will spray oil with high concentrations to ensure the engine operation，Therefore, idle itself is more likely to cause carbon deposits than running or running at a high speed，Long time idle，The carbon accumulation of the engine will definitely be even seabet iomore powerful。Over time, it will affect the efficiency of intake exhaust，Direct spray models are particularly serious，Direct injection vehicles that often idle can see obvious black smoke when cold start。

In fact, the air filter element is like a mask with a human belt。If the air filter cannot effectively filter the suspended particulate matter in the air，Light Those Accelerate the cylinder、The wear of the piston and piston ring，Delivery causes cylinder strain，Shorten the service life of the engine。So car owners need to use different uses，Regularly clean the air filter element。

The air filter element is generally replaced after 3 times (this money cannot be saved)。The cleaning cycle can be determined by the air quality of the daily driving area。Xiao Dong reminds a sentence，Buying the original part of the main factory air filter element provided by the original manufacturer is also very important。

Some car owners find that after discovering that the coolant is less，I think it can be added with water，Xiao Dong understands! As a replacement scheme in temporary circumstances, you can，But if you want to replace it with water，Don't do this! In fact, the coolant is not just for cooling and anti -freezing，There is also high boiling point、Bubble tendency low、Good viscous temperature、Anti -corrosion and scale anti -anti -anti -anti -anti -anti -anti -anti -anti -anti -anti -anti -stains。

The above characteristics，Ordinary water cannot replace it，Even if it is pure water，The boiling point of the coolant is higher than ordinary water，and it is easy to cause Seabetscale，Covering water -cooled channels and even temperature -saving problems，and the engine may be an irreversible damage due to high temperature alarm or further formation。

If the engine is the heart of the car，The oil is the blood in the heart，Because the working environment of the oil is very bad，So be sure to replace the car with the car regularly in combination with the conditions of usage，and make the amount of oil moderate，Generally, it is better to use the upper and lower limits of the oil label，Too much too little is not good。Don't add less oil，But don't add more。

Xiao Dong remind everyone a sentence，Not the more expensive brand -name synthetic motor oil, the better，The oil that is suitable for your car is the best。Also, don't be greedy for cheap and unknown motor oil，Otherwise, you are distressed, but your wallet and car love your car。

Vehicle modification is a fever for the car，Projects loved by car idiots。Come a big surround、Ahead Lip、Big rear wing; increase the wheels、Change twisted tooth shock avoidance, etc.，In fact, all are small case。What is the real "dressing pig and eating tiger"? Those who play (Tu) home (heroes) will re -adjust the engine，Even the cylinder to increase the displacement。And the damage to the engine is huge。

Imagine! The original car engine is disassembled and then re -assembled，Screws connected everywhere、Fixed clamps, etc. will cause different degrees of wear，This causes the physical structure to damage the original engine，A reduction of engine service life。
