Patent ID: 7559304

Claim:
A control device of an internal combustion engine, having a plurality of cylinders, comprising: stopping condition judging means for judging whether a stopping condition of the engine is established or not; and a throttle valve provided in an intake passage of the engine for controlling an air quantity of air flowing into each cylinder of the engine; wherein the throttle valve decreases the air quantity flowing into the cylinders from when the stopping condition is established until a rotational speed of the engine reaches a preset rotational speed, wherein the throttle valve increases the air quantity flowing into an explosion stroke cylinder and a compression stroke cylinder, when the rotational speed of the engine is below the preset rotational speed, wherein the preset rotational speed is the speed at which the engine actually stops when a crank shaft of the engine rotates for one more cycle, and wherein after increasing the air quantities flowing into the explosion stroke cylinder and the compression stroke cylinder by increasing the valve-opening degree of said throttle valve, said throttle valve is closed at a point of time when judging that the air quantities in said explosion stroke cylinder and in said compression stroke cylinder each come to a specified air quantity upon closing said throttle valve, and said internal combustion engine is, when restarting said internal combustion engine, restarted in the valve-closed state of said throttle valve.
