喷油泵主要用在的汽车柴油机上，喷油泵总成通常是由喷油泵、调速器等部件安装在一起组成的一个整体。其中调速器是保障柴油机的低速运转和对最高转速的限制，确保喷射量与转速之间保持一定关系的部件。而喷油泵则是柴油机最重要的部件，被视为柴油发动机的“心脏”部件，它一旦出问题会使整个柴油机工作失常。
The fuel injection pump is mainly used in the automobile diesel engine. The fuel injection pump assembly is usually a whole composed of fuel injection pump, governor and other components installed together. Among them, the governor is the component that ensures the low speed operation of diesel engine and the maximum speed limit, and ensures that the relationship between injection volume and speed is constant. The fuel injection pump is the most important part of the diesel engine, which is regarded as the "heart" part of the diesel engine. Once it goes wrong, it will make the whole diesel engine work abnormally.
