Control device for internal combustion engine

Abstract

The control device of the internal combustion engine calculates the target rotational speed so that the target rotational speed increases as the engine coolant temperature decreases when the shutdown request of the internal combustion engine is detected. Next, racing is executed by the fuel injection is continuously executed until the engine rotational speed reaches the target rotational speed in a state where the throttle valve is fully opened. Further, the control device stops the fuel injection in a state where the throttle valve is fully opened when the engine rotational speed reaches the target rotational speed. When the output shaft of the internal combustion engine is rotated by inertia to scavenge the inside of the cylinder of the internal combustion engine, moisture generated on the inner wall of the cylinder can be blown off, so that occurrence of misfire can be suppressed.
