Injection pump action

Injection pump function, injection pump seal manufacturers to introduce it for you:

    The function of injection pump (high pressure pump) is to deliver high pressure fuel to injector in time and quantitatively according to different working conditions of diesel engine. The injection pump of multi-cylinder diesel engine should ensure that the oil supply sequence of each cylinder corresponds to the working sequence of diesel engine. Each cylinder oil supply interval angular deviation is not more than 1 ° ~ 2 °; The oil supply of each cylinder shall be uniform, and the non-uniformity shall not be greater than 3% ~ 4% under rated working conditions. In order to avoid the phenomenon of dripping oil when the injector works, the injection pump must ensure that the oil supply is timely and the oil is stopped simply.
