ABSTRACT Development of internal combustion engine has been directed by energy saving and environment protection for a long time. Because lean burn technique has great potential to improve fuel consumption and emissions, it has been paid much attention. Variable induction and twice injection [patent no. 98107693. 9] , which have been developed in recent years, have also shown good effect on engine performance.

能源与环境现已成为内燃机技术发展的主导因素，稀薄燃烧由于其能够很好地改善发动机燃油经济性和排放特性而受到广泛重视；可变进气、二次喷油[专利号：98107693.9]等近年来发展起来的技术也表现出良好地改善发动机性能的能力。

Based on the former works by our group, the variable induction devices including swirl and tumble variable devices were developed and the variable induction and twice injection were combined to optimize the lean burn combustion and improve fuel consumption and emissions in this thesis.
