Computation Methods of Rate of Heat Release in Swirl Chamber Diesel Engine

In this paper, the research progress on computation methods of heat release rate in swirlchamber diesel engine is reviewed f and the effects of the discharge coefficient of connecting passage,on the accuracy of compunction results are analysed in detail. A computation model which considersinstantaneous passage discharge coefficient and can calauate the rates of heat release of multifules isestablished. An example of computation results of heat release rate of a Model S195 diesel engineoperating on diesel fuel is given. The compunction programs in this paper features higher accuracy andwider application range.
