摘　　要：本文探讨了非直喷式柴油机零维热力学模型计算精度的有关问题.指出了合理选择主、副室的代用燃烧函数和正确确定主、副室间连接通道瞬态流量系数,是提高模拟计算精度的有效途径;并在S195涡流室柴油机上得到实际验证.This paper presents a discussion over the problems related to the calculating precision of zerodimensional (thermodynamic) model for indirect injection diesel engines.It is found that reasonable selection of combustion function of the main and vice chambers and correct determination of the flow coefficient between these two chambers are effective ways of increasing the simulated calculating precision.This conclusion is proved by means of tests on a S195 swirl chamber diesel engine.
