【摘要】 利用GT-FUEL软件建立了电控单体泵燃油喷射系统的仿真模型,该模型以德尔福电控单体泵EUP、可压缩高压油管以及机械式一级弹簧喷油器组成的燃油喷射系统为原型。仿真与试验结果的对比表明,该仿真模型能较好地体现电控单体泵燃油喷射系统的液力特性以及各个工况下的喷油速率等。该模型可应用于电控单体泵燃油喷射系统的设计,为开发电控单体泵柴油机提供有价值的参考。更多还原

【Abstract】 A simulation model for electronic unit pump fuel injection system was built up with GT-FUEL.This model is based on the Delphi EUP,compressible high pressure pipe and mechanical injector with one spring.The compare of simulation and experiment results indicate that this simulation model can well reflect the electromagnetic and hydraulic characteristics of the fuel injection system,as well as the fuel injection rate and fuel quantity.It also can provide valuable advice to the design of fuel injection system.更多还原
