Abstract

PURPOSE: To correctly control an air-fuel ratio of the mixture for an engine, by intermediately providing a control valve, that opens correspondingly to the opening operation of a throttle valve at the secondary side of a dual carburetor, in a superchange line and controlling the quantity of supercharge in accordance with an opening degree of the throttle valve at the secondary side.
CONSTITUTION: In operation with a low load, only a carburetor 16 at the primary side of a dual carburetor 18 is used, and a throttle valve 17a of a secondary side carburetor 17 and a control valve 23 in a supercharge line 14 are kept in a state of full close, while a secondary air control valve 24 is opened. In operation with a high load, the primary and secondary side carburetors 16, 17 are used, and the control valve 23, intermediately provided in the supercharge line 14, is opened in accordance with the opening degree of the secondary side throttle valve 17a through a link mechanism 22 to supply the air delivered from a supercharger 19 by the amount in accordance with its opening degree to a combustion chamber 5 from a supercharge port 8. While the secondary air control valve 24 is closed to stop the supply of secondary air.
