引言节省能源是一个重要课题,它与人们生活的各个领域有关。从发动机燃烧方面节能,其主要途径就是改进燃烧方式,改进燃烧室和燃料喷射系统,以及采用增压措施。目前关于发动机燃烧的研究主要集中在以下三个方面: 1)一般火花点火发动机采用稀混合气燃烧; 2)分层充气火花点火发动机的研究; Introduction Saving energy is an important issue that relates to all areas of people's lives. The main ways to save energy from engine combustion are to improve the combustion method, to improve the combustion chamber and fuel injection system, and to take booster measures. At present, the research on engine combustion mainly focuses on the following three aspects: 1) the general spark ignition engine adopts the lean mixture combustion; 2) the research on stratified charge ignition spark ignition engine;
