Method of and apparatus for preparation of a combustion mixture for engines with divided combustion space

摘要

Method of and apparatus for preparation of a combustible mixture of different mixing ration for a main combustion chamber and for a subsidiary combustion chamber for an internal combustion engine. In such apparatus there are a main suction channel terminating into the main combustion chamber and a subsidiary suction channel terminating into the subsidiary combustion chamber, both combustion chambers being separated from their suction channels by suction valves. The fuel is injected via an injection nozzle into the suction tract of the engine and the formed combustible mixture is sucked into the main combustion space of the engine. Simultaneously a part of the fuel is taken away from the injected fuel jet by a stream of sucked-in air, forming a combustible mixture which is sucked into the subsidiary combustion chamber of the combustion engine.
