本文在以下三方面对直接喷射式柴油机的放热规律进行了扩展性的研究,改进示功图的测录精度和数据处理,根据热力学第二定律提出了瞬时放热效率的新概念,应用两条韦柏燃烧函数迭加的方法拟合不同工况下的放热率曲线.
In this paper, the exergy law of direct injection diesel engine is expanded in the following three aspects to improve the recording accuracy and data processing of dynamometer. According to the second law of thermodynamics, a new concept of instantaneous heat release efficiency is proposed. The Fabry-Perot combustion function superposition method is used to fit the heat release rate curve under different conditions.
