| Abstract: | Research was done by aiming at influence to system of the cold start performance of Electric Fuel Injection （EFI） gasoline engine, including starting system, ignition system and EFI system. Based on the contrast experiment on schemes of these systems on actual cars, the detailed influences from which on the cold start of EFI gasoline engine was analyzed. The experiments prove that optimizing the starting system, ignition system and EFI system can effectively improve the cold start performance, and then get the optimal matching data of each system. |
