PURPOSE:To make easy the restarting of an engine at a high temperature by controlling the opening of a throttle valve when starting the engine based on the water temperature and intake air temperature. CONSTITUTION:The temperature of a cooling water for an engine 1 is detected by a water temperature detecting device 7, and the temperature of an intake air is detected by an intake air temperature detecting device 5. When the state of starting an engine is detected by a starting state detecting device 8, the opening of a throttle valve is obtained by an opening signal generating device 14 based on the water and intake air temperatures. Based on this throttle valve opening, an open/close device 15 opens/closes the throttle valve to prevent the air-fuel ratio from rising too high when restarting at a high temperature. In this way, the air-fuel ratio can be prevented from getting too high even when percolation occurs, and the engine can be easily restarted. |
