摘要
针对气体燃料发动机燃气成分多变等特点，从双燃料分开式燃烧室这一情况出发，以各室工质的瞬时成分、温度来计算其比热、内能、焓等热力参数，建立了以实测燃烧室压力为输入参数的放热率分析模型，适用于纯液体燃料、气体燃料以及双燃料工况下直喷式、分开式燃烧室发动机放热率的分析计算。
On the special characteristics of many kinds of gas fuels in gas engines,data about specific heat, inner energy,enthalpy, etc. were calculated according to the composition of gas in main and sub chamber.A computer model of heat releasing rate for gas engines was developed based on present models of IDI engines. The model could be used to calculate heat releasing rate of diesel fuel, gas fuels and dual fuel DI/IDI engines with different input data.Some calculation results were also given in this paper.
