| Abstract: | Gasoline Direct Injection(GDI) has become an important means to improve the economical performance and decrease the emission level for the coming gasoline engines. Injection process has a great influence on this new type of combustion. Three dimensional numerical simulation to GDI in cylinder process for a family car engine was carried out. The influence of the injection timing and the injection angle was studied. The result shows that the choice of appropriate injection parameters influences greatly the preparation of in cylinder mixture and the following combustion. |
