Misfiring preventive device for multi-cylinder internal combustion engine

Abstract

Abstract PURPOSE: To prevent an operation of misfiring of the engine, by decreasing a feed amount of fuel partially to the cylinder, when the engine is in an operation of low load, and substantially enriching an air-fuel ratio to the other cylinder, in the multi- cylinder engine having a respectively independent air intake path. CONSTITUTION: Two pistons 2a, 3b are in a motion of sliding in a different phase in a cylinder 2. To a crank case 6a, 6b, in bottom portion of each of the pistons 2a, 3b, is independently linked an air intake path 11a, 11b. In each path 11a, 11b, is provided a carburetor 13a, 13b, simultaneously in a low speed fuel path 20a of one carburetor 13a of them, is arranged a solenoid valve 24. In addition the solenoid valve 24 is made interlocking to a throttle valve 15b of the other carburetor 13b, and a low speed path 20a is closed for the throttle valve 15b to be in a low degree of opening.
