摘　　要：从提高汽车排放性能的角度阐述了汽油发动机燃油喷射技术的研究进展,对进气道喷射、缸内直喷技术及混合喷射技术进行了技术特点和应用车型对比分析。在排放法规日趋严格的大形势下,发展电控汽油喷射系统是必然趋势。The research progress of the gasoline engine fuel injection technology is discussed in this paper from the angle of vehicle emission performance improvement,and the comparative analysis of port fuel injection,gasoline direct injection and mixed injection technology are made in terms of technological characteristics and different vehicle appli-cation models. In the situation that the vehicle emission standards are increasingly stringent,it9s an inevitable trend to develop the electronic controlled gasoline injection systems.
