Research on the Current Status and Trends of Engine Technology Characteristics for Passenger Cars in China
Based on the passenger cars information released by the Ministry of Industry and Information Technology of the People's Republic of China in 2022,researches were conducted on the characteristics of the engines construction and main technology characteristics.Results indicate that in the current field of passenger cars,engines still play an irre-placeable role.For gasoline engines,in order to improve engine power output,fuel economy,and reduce manufacturing costs,the technology route of four-inline cylinder construction,exhaust gas turbocharger,fuel direct injection system,but non-EGR system has been widely applied.Hybrid electric vehicles are a powerful supplement to pure electric passen-ger cars in the process of achieving the dual carbon goals.The future development direction of engine technology for pas-senger cars is still to achieve higher thermal efficiency through various means.And low-carbon,zero-carbon,and carbon-neutral fuels are also the focus of future development.
