Abstract
An internal combustion engine equipped with a sub-suction path to produce a swirl of suction in the combustion chamber, characterized in that there are two inlets to the sub-suction path, one of the inlets opening into the atmosphere side after bypassing the throttle valve of the carburetor to the venturi and the other being operable by the throttle valve of the carburetor and opening in the duct of the carburetor so that it can be closed by the throttle valve at idling. In this arrangement of the engine, the fuel consumption can be saved; a misfiring can be prevented; an untimely or delayed injection of fuel from the main fuel nozzle in low to high load operation can be averted; and a stable combustion can be assured in medium load operation in which a particularly heavy EGR takes place.
