Abstract

PURPOSE: To prevent a misfiring of the engine, by reducing a feed amount of fuel partially to the cylinder, when the multi-cylinder engine is in an operation of low load, and substantially enriching an air-fuel ratio to the other cylinder.
CONSTITUTION: In a cylinder 1a are in a motion of sliding a plurality of pistons 2a in the same phase. To a combustion chamber 7a, in top of the piston 2a, is linked an exhaust port 11a, and to a crankcase 3a, in bottom portion of the piston 2a, is linked an air intake port 13a having a carburetor 14a. In the carburetor 14a, a variable valve 17a controls the area of a nozzle 19a according to the opening degree of a throttle valve 16a. And between the throttle valve 16a and the variable valve 17a, is provided an idling fuel path 20a linked to a float chamber 18a, simultaneously in this path is provided a solenoid valve 21 working in response to a negative pressure switch 22, and for a relatively big suction negative pressure when in a low load operation of the engine, the path 20a is closed.
