The course consists of two parts. The first part explains the engine's power output, i.e. power, and energy conversion efficiency, i.e. fuel economy, from the perspective of the whole machine and the macroscopic perspective, including engine performance indicators and influencing factors, fuel, working fluid and thermochemistry. Working cycle and energy utilization, ventilation process and intake air charge, operating characteristics and vehicle matching, etc. The second part explains the combustion process and emission characteristics of the engine from a local and micro perspective, including basic knowledge of combustion, mixture formation and combustion of diesel and gasoline engines, harmful substance generation mechanism and control, new combustion methods and alternative fuel engines wait. During the course teaching, the comparative analysis of gasoline engines and diesel engines is always carried out so that students can better understand the working principle of the engines.

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.
