【Abstract】 In this paper the combustion heat release rate of Sofim 8140.21 high speed Supercharge Diesel Engine of Vehicle is described. The power indication diagram of various working conditions was measured by using multi-channel ICE combustion analyz- er. According to the diagram the combustion heat release rate has been calculated. And then the charcteristic parameters of heat release and their influence on the performance of engine were diacussed in detail更多还原
