A traction control device in an engine which has an intake passage. A throttle valve and a flow control valve are arranged in series in the intake passage. Where acceleration of the motor vehicle is carried out, when the speed of rotation of the driven wheel or acceleration of the speed of rotation of the driven wheel exceeds a predetermined level, the flow control valve is closed. When the speed of rotation of the driven wheel becomes lower than a predetermined level or deceleration of the speed of rotation of the driven wheel becomes larger than a predetermined level, the flow control valve is opened.
