喷油泵顶隙柱塞供油特性研究

Fuel Delivery Characteristics of Top Clearance Plunger in Injection Pump

对喷油泵顶隙柱塞、普通柱塞供油特性进行试验,通过对喷油泵泵端压力、嘴端压力、喷油规律及喷油量的研究,对比分析顶隙柱塞与普通柱塞的喷油提前特性及喷油特性差异。

The fuel delivery characteristic experiments of the top clearance plunger and the normal plunger are made.The pump pressure,nozzle pressure,injection profile and injection quantity of pump are studied.The character of injection advance and injection characteristic are different between the top clearance plunger and the normal plunger.
