During the engine starting process, the speed always gets up and back to idle speed slowly, in order to solve these problems, and at the same time to control the combustion during the starting process more accurately, a gasoline engine starting strategy based on air–fuel ratio (AFR) control is developed, including intake airflow control, AFR control, and so on. By selecting the appropriate airflow and AFR, the fuel injection amount is calculated, and the test results show that the engine can start up quickly and reliably, and the starting speed will have a smooth transition to target idle speed. |
