In an engine provided with a variable valve mechanism which varies an operating angle of an intake valve and a lift amount thereof, when an engine operation is automatically stopped after the establishment of an idling stop condition, the operating angle of the intake valve and the lift amount thereof are varied to be smaller, so that a load of the variable valve mechanism at an engine operation restarting time is low. Then, when the engine operation restarting is requested, a first explosion pressure is obtained by performing fuel injection and ignition on a cylinder stopped in an expansion stroke, so that the engine operation is started. Further, after a first intake stroke, the operating angle of the intake valve and the lift amount thereof are increased.
