Zusammenfassung:	PROBLEM TO BE SOLVED: To cope with the large displacement of an engine without manufacturing a novel fuel injection valve, and to improve cooling effect of the engine. SOLUTION: An auxiliary fuel supply passage 20 for flowing boosted auxiliary fuel is opened in an intake air passage 12 of an intake air control device 11. The intake air passage 12 is connected to the inside of a crank chamber 9 of the engine E via reed valve 10. The auxiliary fuel supply passage 20 is opened and closed by a solenoid control valve S. The solenoid control valve opens the auxiliary fuel supply passage 20 in opening larger than specific high opening of a throttle valve 13 and a specific high rotating speed or more.
