FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: invention relates to fuel-feed control systems of internal combustion engine, and it can be used in gasolines of automobiles. Proposed fuel injection system of internal combustion engine contains fuel tank, unit of electromagnetic nozzles connected to each other and intake manifold of internal combustion engine and electronic control unit connected by inputs with sensors installed on engine and by outputs, with electromagnetic nozzle unit. Fuel tank consists of two spacers, upper and lower ones, connected, respectively, by pipelines with electric compressor and with shutoff valve, fuel filter, fuel accumulator and fuel pressure regular connected in succession by pipelines. Spring-loaded diaphragm is installed in housing of fuel tank between upper and lower spaces. Input of electric compressor are electrically connected with fuel pressure regulator and with output control unit, and inputs of shutoff valve and fuel pressure regulator are electrically connected with outputs of control unit.
EFFECT: improved reliability of fuel injection system of internal combustion engine.
