Abstract

An externally ignited internal combustion engine, operable by a homogeneous fuel, wherein liquid fuel is completely vaporized and at an approximately relatively lean proportion is mixed with air to provide for quantity control of the fuel-air mixture. The quantity control remains limited to a lower part throttle or partial load range and above such range, fuel in a liquid condition is injected into the combustion chamber of the internal combustion engine to enable a quality control over the fuel mixture. The injection of the fuel is carried out so that the injected jet of fuel does not contact the relatively cold wall parts of combustion chambers of the respective cylinders of the internal combustion engine.
