摘要

在GT-Power仿真软件平台建立采用单级涡轮增压的柴油发动机一维仿真模型，并且将实验数据与仿真数据进行对比

验证了所建立的模型的准确性和合理性。在此基础上，研究稳态工况中不同发动机转速下涡轮增压器放气阀开度（指放气阀流通直径）对发动机的输出功率和比油耗的影响并总结规律。然后，以输出功率最高、比油耗最低为优化目标，实现外特性各转速下放气阀开度的优化。最后，探究发动机加速动态工况下，不同放气阀开度对发动机性能的影响规律。结果表明：放气阀开度越小，发动机加速性能越好，与压气机的匹配效果越好。

Abstract

A one-dimensional simulation model of diesel engine with single-stage turbocharging is established on the GT-Power simulation software platform

and the accuracy and rationality of the model are verified by comparing the experimental data with the simulation data. On this basis

the influence of the turbocharger wastegate opening (referring to the wastegate flow diameter) on the engine output power and specific fuel consumption at different engine speeds under steady state conditions is studied and summarized. Then

taking the highest output power and the lowest specific fuel consumption as the optimization objectives

realize the optimization of wastegate opening under various speeds of external characteristics. Finally

the influence of different wastegate openings on engine performance under engine acceleration dynamic conditions was investigated. It was found that the smaller the wastegate opening

the better the engine acceleration performance and the matching effect with compressor is better.
