摘　　要：以某一电喷汽油发动机为研究对象，利用现代先进技术——可变进气歧管结构和可变气门定时，提出优化方案，对其进行结构设计，利用BOOST模拟计算软件，建立可变的进气和配气系统模型，分析影响进气充量的各种因素，并通过实验进行验证。This thesis studies on a certain gasoline engine of electronically controlled injection system, to which the modern advanced technologies such as variable intake manifold technology and variable valve timing are adopted. In this thesis an optimal scheme is brought forward and made a simulation with Boost to establish a model of variable inlet charge system and valve timing system, which designs the structure of the engine. The other factors which affect inlet charge are analyzed. The optimal scheme is also testified by an experiments.
