A control device is described of an internal combustion engine which consists of: an intake passage; a throttle valve arranged in the intake passage; switch means operated in response to the degree of opening of the throttle valve and producing an output signal representing a state wherein the degree of opening of the throttle valve is greater than a predetermined degree; a vacuum sensor arranged in the intake passage and producing an output signal representing the absolute pressure therein; discriminating means operated in response to the output signals of the switch means and the vacuum sensor for discriminating whether the absolute pressure decreases by a predetermined pressure after the degree of opening of the throttle valve becomes smaller than the predetermined degree to produce an output signal representing a state wherein the absolute pressure decreases by the predetermined pressure after the degree of opening of the throttle valve becomes smaller than the predetermined degree; a swirl control valve arranged in the intake passage for creating a swirl motion in a combustion chamber when the swirl control valve is closed.
