摘要
随着我国汽车保有量的增加,能源问题和环境问题对传统内燃机的发展提出巨大挑战,米勒循环发动机以其特有的工作原理,能够明显提高发动机的热效率,改善发动机的燃油消耗,满足日益严格的油耗法规。文章对米勒循环汽油机的工作原理进行了分析,并通过试验验证了米勒循环对汽油机油耗率的影响,为米勒循环在汽油机上的应用提供参考。
As the increase of vehicles in China,energy problems and environmental problems pose great challenges to the development of traditional internal combustion engines.The Miller cycle engines,with their unique working principles,can significantly improve the thermal efficiency of the engine,reduce the fuel consumption of the engine,and meet increasingly stringent fuel economy regulations requirement.This paper analyzes the working principal of Miller cycle engine,and verifies the effects of Miller cycle on engine performance by experiment,which provides reference for application of Miller cycle on the gasoline engine.
