PROBLEM TO BE SOLVED: To start an internal combustion engine even when the amount of power charged a battery decreases, or in an ultra-low temperature, and so on.SOLUTION: When a battery voltage at the start of the internal combustion engine is below a threshold value, fuel is injected from an injector when the battery voltage takes a maximum value. The voltage applied to a fuel pump at the moment of fuel injection is increased accordingly, thereby securing a discharge pressure and discharge amount of the electric fuel pump which supplies the fuel to the injector. |
