PURPOSE:To improve the acceleration performance by cooling the supercharged air for a proper time with an inter-cooler during the acceleration of an engine. CONSTITUTION:In an operation area where a throttle valve 9 is not quickly opened, the supercharged air from a blower compressor 6 passes a supercharge passage 7 and is fed to an engine without passing an inter-cooler 19. During the acceleration with the throttle valve 9 quickly opened, a transfer valve 21 is switched, the supercharged air from the blower compressor 6 passes the inter- cooler 19 and is cooled by the inter-cooler 19, and the air density is increased and the output of the engine is increased. |
