文摘

A quantitative analysis on the key influencing factors of engine thermal efficiency was focused. The control equations for engine in-cylinder thermal efficiency were deduced and verified. The influence factors of engine heat-work conversion efficiency were disintegrated. There is a strong similarity between the curves of indicated thermal efficiency and the EER.
