とする始動制御機構。 Main and sub-bypass air passages that bypass the throttle valve and communicate with the intake passage on the upstream and downstream sides thereof are provided with a main throttle and a sub-throttle, respectively, and are connected to valves that control opening and closing of the main bypass air passage. The main and sub-bypass air passages are partitioned by a diaphragm, and the opening degree of the valve is controlled according to the air flow rate of the sub-bypass air passage whose opening degree is controlled according to the engine cooling water temperature. In an engine equipped with an air control device, an elastic member is provided in the valve or the main bypass air passageway, and has elasticity sufficient to cause the valve to open slightly during engine starting and cranking, and to close the valve when the engine is completely exploded. A starting control mechanism characterized by:
