A fuel supply apparatus in an internal combustion engine in which a venturi provided in the intake passage of the engine is provided with a fuel discharging opening, and the discharge opening is in communication with a fuel-air mixture producing source at which the fuel-air mixture is produced by mixing the external air and the injection fuel injected from a fuel injection nozzle.

Fuel supply apparatus in internal combustion engine

Constant differential pressure valves, one for each cylinder of the engine, supply liquid fuel to the injection nozzles. The liquid fuel supplied to the valves is delivered from a chamber within a metering member mounted to turn within the bore of a stationary sleeve. A plate carried by the metering member has notches on its periphery which cooperate with openings in the enclosing sleeve to form variable orifices. The metering member is turned in proportion to the rate of air flow through an air intake passage for the engine.

Fuel supply control device for fuel injected internal combustion engine

Exhaust gas from an internal combustion piston engine is recirculated through a rich mixture auxiliary intake passage leading to an auxiliary combustion chamber. A valve controls the relative proportions of exhaust gas and air supplied to the auxiliary intake passage, and the valve is controlled by means responsive to suction pressure downstream from the auxiliary throttle valve, and is also responsive to movement of that throttle valve.
