摘　　要：当前我国各内燃机制造厂所广泛应用的实际循环计算方法,是一种近似的、半经验的估算方法,其计算结果的精确性依赖于大量经验数据的选取是否恰当,从而影响了它对实际工作的指导意义,因此作用十分有限。我们对它进行计算的目的是:在一台新内燃机的设计过程中,大致的确定其汽缸内的压力和温度变化情况,绘制其示功图,为以后所必须进行的动力计算和强度计算提供原始数据,同时,它还可以对发动机方案设计中所确定的指标、尺寸、结构起到一定的校核作用。Most of the internal combustion manufacturers use an estimated method with approximation and semi-experience in calculation of heat circulation, with which the accuracy relies on the appropriate selection of large amount of experienced data, thus, losing the meaning in directing the actual work. The author made this calculation with purposes for providing original data for power and strength calculation by roughly determining the variation of pressure and temperature inside the cylinder and then giving the indicator diagram of work. Meanwhile, it may also play a role in checking the index, dimension and structure determined in the engine design.
