In order to analyze the relationship between radiation heat transfer and thermo-efficiency, the radiant heat flux of the cylinder and thermal balance are measured. The results show that: The reduction of thermal radiant flux in the cylinder is the primary cause of the improvement of thermal efficiency of the engine.

为了研究发动机热效率和辐射传热量变化之间的关系，利用辐射传感器测量了柴油机燃用DMC柴油混合燃料后缸内辐射传热量，进行了热平衡实验，分析结果表明，添加含氧燃料后，发动机缸内辐射传热量的减少是导致其有效热效率的提高的主要原因。
