摘要
通过发动机台架试验,研究了排气背压对柴油机性能的影响,绘制了参数敏感度曲线,得到了排气背压对柴油机性能参数影响的敏感度排序,并对各参数敏感度变化进行了比较分析。为汽车排气系统设计和参数选择提供了依据。
Influence of exhaust pressure on the engine performances based on the engine tests is investigated.This paper draws sensitivity curveo,btain performance parameters of diesel engine exhaust back pressure effect on the sensitivity of sequencing,and changes of sensitivity in the parameters of a comparative analysis,which provides the basis for automotive exhaust system design and parameters.
