摘　　要：为进行柴油机和增压系统的匹配,发展了一种模拟计算方法。该计算方法包括缸内工作过程的简化计算、进排气过程计算、柴油机的功率计算、增压系统计算等计算模块。对柴油机缸内过程的计算,采用定容定压循环代替实际循环。对增压系统的计算,是根据压气机特性图和涡轮特性图进行的。对J6110Z增压柴油机进行了模拟计算,模拟计算的结果与试验结果比较接近。A simulation method for matching diesel engine and turbocharging system was developed. The simulation method comprised simple calculations of inrcylinder cycle, intake and exhaust period calculations, effective power output calculations, turbocharging system calculations and other calculations. A constant volume and constant pressure combined cycle was used to simulate in-cylinder real cycle. Turbocharging system simulation was performed based on detailed compressor performance maps and turbine maps. A J6110Z diesel engine was simulated, the simulation results agreed with test results.
