ABSTRACT:
An internal combustion engine, which is equipped with a sub-suction path for generating a swirl of the suction gas in the combustion chamber in addition to a main suction path to be opened or closed by a suction valve. The sub-suction path is equipped at its inlet side paths with two fuel supply device-line and atmosphere-line paths, the former of which is opened into the draft passage of a fuel supply device and between the air metering portion of said fuel supply device and a throttle valve downstream of the air metering portion and the latter of which is vented to the atmosphere while bypassing said air metering portion and said throttle valve. With the aforementioned atmosphere-line path, moreover, there is connected a vacuum-operated valve which is made operable in accordance with the vacuum prevailing downstream of said throttle valve.
