FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: proposed fuel feed system consists of fuel tank, electric pump with installed-behind fuel pump with mechanical drive, filter, fuel manifold with electromagnetic nozzles, reducing valve and electromagnetic valve. Electromagnetic valve, when de-energized, communicates fuel manifold space with additional fuel manifold provided with spraying device controlled by fuel meter. System contains also control unit with sensors. Fuel meter is installed united bloc with central injection unit with spraying device in form of one central nozzle communicating with additional fuel manifold in form of fuel main line, at inlet of which electromagnetic valve is installed in parallel with reducing valve. Fuel meter maintains required pressure in fuel main line. Control cam of fuel meter is installed directly on axle of throttle valve, and fuel meter drain main line communicates with fuel tank.
EFFECT: simplified design of fuel system, increased accuracy of fuel feed.
