进入冬季,由于气温的下降,汽车变得很难启动。一些人习惯将发动机启动起来以后原地进行一下热车,这样做一方面可以提高发动机本身的温度,有利于柴油在气缸中与空气更加均匀地混合后进行燃烧做功;另一个方面通过原地怠速的运转,带动柴油机润滑系中的机油能够充分地到达发动机各个需要润滑的部位进行润滑,以减小不必要的磨损,提高发动机的使用寿命。当然适度地热车是非常有必要的,但是现在很多人习惯将汽车长时间地热车,认为这样做能够提高汽车发动机的使用寿命,其实这种做法是非常错误的,下面我们重点讲解一下柴油发动机长时间热车的危害有哪些。
Into the winter, due to the temperature drop, the car becomes difficult to start. Some people are accustomed to the engine started up after the hot car, in doing so can improve the engine’s own temperature on the one hand, is conducive to diesel in the cylinder more evenly mixed with the air after the combustion work; the other hand, through the idle speed Of the operation, led the diesel engine lubrication system oil to fully reach all parts of the engine lubrication required to reduce unnecessary wear and improve engine life. Of course, modest hot car is very necessary, but now many people are accustomed to the car hot car for a long time, that doing so can improve the life of the car engine, in fact, this approach is very wrong, here we focus on explaining the diesel engine length Time hot car what are the hazards.
