FUEL FEED SYSTEM OF INTERNAL COMBUSTION ENGINE Russian patent published in 2005 - IPC

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: proposed fuel feed system of internal combustion engine contains reservoir with hydrocarbon fuel connected with pump for supply of hydrocarbon fuel and provided with pressure regulator, at least one nozzle connected by pipeline to hydrocarbon fuel supply pump. Pump housing is provided with channel to supply hydrocarbon fuel to atomizer, source of additions connected with addition feed meter which is furnished with spring-loaded single-stroke shutoff valve, mixing and accumulating chamber coupled with channel to feed hydrocarbon fuel to atomizer, and with channel to feed additions to atomizer connected by main line with addition feed meter. Spring-loaded single-stroke shutoff valve prevents reverse flow of additions being furnished with jet in contact with needle valve. Needle valve is connected through step motor with control mechanism. Mixing and accumulating chamber coupled with high-pressure pipeline is arranged out of nozzle body, being divided by porous ceramet insert onto spaces, one of which is connected with channel to supply hydrocarbon fuel to atomizer, and the other is connected with addition feed meter.

EFFECT: reduced consumption of fuel and toxicity of engine.
