An apparatus for controlling an ignition timing of a cylinder-injection gasoline engine includes an electronic control unit (ECU) for controlling the operation of an ignition coil. The ECU advances the ignition timing in accordance with the throttle opening in consideration of a delay in increase of the wall temperature of a combustion chamber when the acceleration of a vehicle is detected by the change of the throttle opening. In order to prevent knocking of the engine attributable to the increase of the wall temperature, the ECU gradually decreases an advance angle for the ignition timing to 0 with the passage of control time. When the engine is reaccelerated during the advance angle correction, the ECU newly sets an advance angle for the ignition timing and a control time, corresponding to the increase of the wall temperature.

A structure of internal combustion engine comprises a cylinder member composed of a cylinder which accomodates a piston connected with a crankshaft, a crankcase provided to accomodate said crankshaft, a rocker case provided to accomodate a valve actuating mechanism, an oil return passage constituting means for leading oil in said rocker case into said crankcase, and a restraining means for restraining an air flow within said crankcase from entering into said oil return passage constituting means. By the effect of the restraining means provided in relation to the oil return passage constituting means, the air flow generated by the rotation of the crankshaft does not work as a dynamic pressure of hingering the flowingdown of oil.
