摘　　要：柴油机热平衡计算是缸内传热研究的重要环节,其目的在于分析柴油机不同工况下燃料燃烧产生的热量分配情况,为柴油机各系统与柴油机的匹配提供优化依据。柴油机热平衡计算主要有仿真与试验2种方法,利用GT-POWER软件建立了柴油机热平衡的仿真计算模型,并针对一种柴油机进行了外特性与负荷特性的热平衡仿真计算,为柴油机热平衡仿真研究提供了一种新的计算方法。Diesel engineg thermal balance calculation is an important part in the research of engine cylinder heat transfer wilh the pro＇pose to analyze the distribution of the fuel combustion heat under different working conditions and to provide important theoretic guidance for optinml designs of diesel engine. Simulation and test are tile two common methods of diesel engine thermal balance calculation. In this paper,diesel engine thermal balance model is established by the software of GT - POWER, and the thermal balance of a specific diesel engine under external characteristics and load characteristics is worked out, providing a new way to calculate diesel engine thermal balance.
