摘　　要：进排气系统压损对于发动机的性能及动力性、经济性具有十分重要的影响,借助发动机台架及整车上的不同压损对比测试,通过测试数据的整理对比分析,直观展现出不同压损对发动机的影响。The pressure loss of the intake and exhaust system has a very important impact on the performance,power and economy of the engine.Through the comparison test of different pressure losses on the engine bench and the whole vehicle,the influence of different pressure losses on the engine is intuitively demonstrated through the collation and comparative analysis of the test data.

关 键 词：进排气系统 压损 发动机性能 动力性 经济性
