Abstract
PURPOSE: To supply air-fuel mixture in advance immediately before shifting from the low load running to high load running for preventing the lowering of air-fuel ratio by connecting a supply route of air-fuel mixture to the intake passage downstream of a throttle valve and providing the same with a switching valve to control.
CONSTITUTION: An air-fuel mixture supply passage 22 is made to connect to the intake passage for high load from the bottom of the carburetor for high load 9 in the lower course of the throttle valve 15 for providing a switch valve 26, while the first control device 31, which operates detecting warming-up, the second control device 33, which operates detecting just before starting operation of the throttle valve for high load 15 and the third control device (a sketch), which operates detecting quick acceleration are provided and so formed as to off-operate the switching valve 26 respectively and supply air-fuel mixture in advance from just before the throttle valve for high load is opened. Thereby the deterioration of running on the transient stage shifting from the single use region of the carburetor for low load 7 to the joint use region of the carburetor for high load can be prevented.
