Zusammenfassung:PURPOSE:To improve efficiency of combustion and fuel consumption, by providing a thermo valve which sensibly detects temperature of an engine to control openeing and closing and opening degree of a passage supplying air to the engine. CONSTITUTION:An air pump 9 is operated by change of pressure in a crank chamber 5 to inject air into an engine 1 from an air hole 6 through an air cleaner, thermo valve 10 and check valve 8. When the engine is cold, the valve 10 is closed or placed in a small opening, and air is not injected into the engine 1. While at warmed time of the engine, the valve 10 is opened or placed to a large opening, then the air is injected.
