【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。更多还原

【Abstract】 A simulation method for matching diesel engine and turbocharging system was developed.The simulation method comprised simple calculations of in-cylinder 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.更多还原
