ABSTRACT:
An engine has separate cylinders to which rich and lean mixtures are respectively supplied. A common carburetor that is set to make a rich air-fuel mixture is used for feeding both rich and lean mixtures. An air-supply passage is connected to an intake manifold that communicates the carburetor with the cylinder to which lean mixture is fed. The air introduced from the air-supply passage is mixed with the rich mixture to produce the desired lean mixture. A valve unit is installed in the air-supply passage, so that the rich mixture is fed to all the cylinders during high-load operation by closing the valve.
