CONTROL DEVICE AND CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE

摘要

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.
