Influence of Drain Back Pressure on High Pressure Common Rail Injector performance
The high-pressure common rail injector is the most important component in the high-pressure com-mon rail electronic control system of diesel engines,and its fuel injection characteristics(such as injection quanti-ty)will directly affect the performance of the engine.The injection characteristics of an injector are not only in-fluenced by the structural parameters of the injector,but also by the external working environment during the in-jection process,such as the engine cylinder pressure and the drain back pressure.This article mainly focuses on bench test on one type of high-pressure common rail injector,studies the influence of injector drain back pressure on injection characteristics,and analyzes the reasons for the impact,provide test data for the development of new high-pressure common rail systems.
