Abstract: The present invention relates to a control device and a control method for an internal combustion engine including a fuel injection valve and an electric fuel pump. In stopping the internal combustion engine, the control device stops driving of the fuel pump and then fuel injection by the fuel injection valve, and increases the total amount of fuel injection by the fuel injection valve after stopping of driving of the fuel pump as the temperature of fuel in stopping the internal combustion engine decreases, thereby reducing a fuel pressure in a stop period. In this manner, fuel leakage from the fuel injection valve in the stop period can be reduced with a simple configuration.

Abstract: The present invention relates to a control apparatus and method for an internal combustion engine including two fuel injection valves in the intake port of each cylinder. In the present invention, fuel injection from a first fuel injection valve is activated while fuel injection from a second fuel injection valve is temporarily stopped at the resumption of fuel injection from the deceleration fuel cut-off state in response to a decrease in the engine rotation speed. The amount of minimum fuel injection to each cylinder that ensures the accuracy of fuel measurement can be reduced, and fuel is injected from the first fuel injection valve in an amount equal to or greater than the amount of minimum fuel injection. Thus, fuel injection can be resumed at a lower engine speed than when fuel injection is resumed from the two fuel injection valves.
