Kursinhalt
课程由两部分构成,第一部分是从整机和宏观的角度,阐述发动机的动力输出即动力性和能量转化效率即燃油经济性,包括发动机性能指标与影响因素,燃料、工质与热化学,工作循环与能量利用,换气过程与进气充量,运行特性与整车匹配等。第二部分是从局部和微观的角度,阐述发动机的燃烧过程与排放特性,包括燃烧的基础知识,柴油机和汽油机的混合气形成与燃烧,有害物生成机理与控制,新燃烧方式与替代燃料发动机等。课程讲授过程中,始终贯穿汽油机与柴油机的对比分析,以便于同学们更好地理解发动机的工作原理。 This course consists of two parts. The first part describes the engine power outputs (dynamic performance) and energy conversion efficiency (fuel economy) integrally, including the engine performance and factors which affects it, fuel, working medium, thermochemistry, the operating cycle and energy utilization, gas exchange process ,intake charge quantity, operation characteristics and the its match of the entire vehicle, etc. The second part describes the combustion process and emission characteristics of the engine ,including the fundamentals of combustion, the mixture formation and combustion of diesel and gasoline engines, the formation and control of harmful substances, new combustion modes and other alternative fuel engines, etc. The comparative analysis between gasoline engine and diesel engine will be conducted during the whole lecture, so that students can better understand the working principle of the engine.
