摘要
针对二冲程发动机排气压力波影响发动机动力性及经济性较为严重的情况，开发研制了排气动力计算程序（ＥＳＣＳ），并以该程序作为工具，对某一５５ｍＬ二冲程发动机的排气压力波进行了分析。
Aiming at the problem of bad tractive performance and fuel economy of two stroke engines, which is seriously influenced by exhaust pressure wave, an engine simulated calculation system is developed. Furthermore a 55 mL two stroke engine exhaust pressure wave is analyzed.
