PROBLEM TO BE SOLVED: To solve the problem of being difficult to improve startability, due to requiring time for raising the cylinder temperature in cold time when an engine grows cold, as a result of becoming difficult to raise compression heat when a supercharger becomes a load to the engine and a quantity of remaining fresh air is not sufficient since the fresh air passes through into a cylinder, in a two-cycle engine. SOLUTION: A vehicle has the two-cycle engine for igniting fuel by compressing suction air, the supercharger for forcibly feeding air to the two-cycle engine, an air supply bypass passage having an air supply bypass valve and bypassing the supercharger, and an exhaust gas quantity adjusting means for adjusting a flow rate of exhaust gas; and controls so as to close the air supply bypass valve and close the exhaust gas quantity adjusting means up to at least initial combustion, and to gradually open the air supply bypass valve and gradually open the exhaust gas quantity adjusting means after the initial combustion, when starting the two-cycle engine.
