汽车发动机正时链条对于发动机来说是非常重要的，正时链条拥有着非常多的优点，正时链条的使用寿命相对来说是比较长的，出现故障的频率相对应其他部件来说也是比较低的，但是不代表在使用汽车时就可以不注意正时链条，我们在汽车行驶超过10万公里之后就应该对正时链条检查一次，看其是否有磨损，故障问题出现。
The timing chain of automobile engine is very important for the engine. The timing chain has many advantages. The service life of the timing chain is relatively long, and the frequency of failure is relatively low compared with other components, but it does not mean that we can not pay attention to the timing chain when using the car. We should check the timing chain after the car has driven more than 100000 kilometers, Check whether there is wear and failure.
如果是常年需要高速行驶的汽车，应该缩短检查正时链条的时间，一般来说5年以内就应该检查一次。如果发动机正时链条损坏，汽车发动机是无法正常工作的，需要进行更换处理，发动机正时链条损坏会产生以下几种情况：
If it is a car that needs high-speed driving all year round, the time for checking the timing chain should be shortened. Generally speaking, it should be checked once within 5 years. If the engine timing chain is damaged, the automobile engine cannot work normally and needs to be replaced. The engine timing chain damage will produce the following conditions:
1、发动机正时链条损坏会引起发动机异响。
1. Damage to the engine timing chain will cause abnormal engine noise.
2、发动机正时链条损坏会导致汽车油耗偏高，机油的消耗增加。
2. Damage to the engine timing chain will lead to high fuel consumption and increased oil consumption.
3、发动机正时链条损坏会导致汽车无法启动。
3. Damage to the engine timing chain will prevent the car from starting.
济南奔驰汽车维修人员认为正时链条在正常情况下可以使用很长时间，有的甚至可以终生免维护，但是也不排除在实际使用的过程中，正时链条出现磨损或者拉长现象，正时链条拉长就会引起异响，这时汽车继续行驶的话就会很容易跳齿，发动机的机油消耗会比平时要高，点火时会发现正时是不对的，这个时候车主就应该注意检查正时链条，以防引起更多的汽车故障问题。
Jinan Benz automobile maintenance personnel believe that the timing chain can be used for a long time under normal circumstances, and some can even be maintenance free for life. However, it does not rule out that in the actual use process, the timing chain will be worn or stretched, and the stretching of the timing chain will cause abnormal noise. At this time, if the car continues to drive, it will be easy to jump teeth, the engine oil consumption will be higher than usual, and the timing will be found to be wrong when ignition, At this time, car owners should pay attention to checking the timing chain to prevent more car faults.
