FIELD: mechanical engineering; internal combustion engine.
SUBSTANCE: proposed fuel system for internal combustion engine has fuel pressure regulator to input of which fuel is pressure-fed, and electronic control unit of fuel system. Normally-closed electromagnetic fuel valve is installed at input of fuel regulator. Output of fuel regulator is connected with one or several normally-open electromagnetic fuel valves. Number of normally-open electromagnetic fuel is equal to number of cylinders. Output of normally-open fuel valves are connected with air ducts (resonators) of engine intake manifold. Normally-closed and normally-open electromagnetic fuel valves are electrically connected with electronic control unit of fuel system.
EFFECT: increased accuracy of cyclic metering out of fuel.
