基于HYDSIM的240/275柴油机E型燃油喷射系统仿真

Simulation of E-type Fuel Injection System For 240/275 Diesel Engine By HYDSIM

本文运用HYSDIM搭建240/275柴油机E型燃油喷射系统仿真模型,并通过试验结果校验仿真模型,以确保仿真的精准可靠;在此基础上,分析了柱塞副泄漏问题,优化了喷孔直径以提升排放水平。

This paper uses HDYSIM to build the simulation model of E-type fuel injection system for 240/275 diesel engine,and verifies the simulation model through the test results to ensure the accuracy and reliability of the simulation.On this basis,the leakage problem of plunger pair is analyzed,and the nozzle diameter is optimized to improve the emission level.
