【摘要】 为分析排气压力波对发动机性能的影响,在MK14程序的基础上研制开发了以进、排气系统为主的发动机模拟计算系统(ESCS),并以该程序作为工具,对某一125ml四冲程发动机的排气压力波进行分析。通过试验分析,应用ESCS系统对发动机的排气净化系统进行模拟计算是可行的、正确的、真实的。更多还原

【Abstract】 The influence of exhaust pressure waves on engine property is analyzed. New simulated calculation software based on MK 14 is developed, which is a powerful tool in developing exhaust system with catalytic converter. The exhaust pressure waves of a 125ml four-stroke engine are analyzed with the software. By further examination and analysis, it can be concluded that the simulation calculation of the engine exhaust evolution system with ESCS is feasible and authentic.更多还原
