ABSTRACT OF THE DISCLOSURE An air-fuel ratio control apparatus for an internal combustion engine has an air valve disposed in an intake passage downstream of a throttle valve to cooperate therewith to define an air pressure chamber and operative to maintain a substantially constant pressure therein. A fuel circuit includes a fuel discharge port open to the intake passage and a fuel-metering orifice operatively associated with the air valve such that the fuel-flowing section of the orifice is varied in proportion to the air-flowing section of the air valve. A constant differential fuel pressure valve is disposed in the fuel circuit to maintain a substantially constant fuel pressure difference across the fuel metering orifice during normal engine operation. The differential fuel pressure valve is mechanically operatively connected to a piston-cylinder assembly into orifice is introduced. The position of the piston relative to the cylinder is varied when the piston varies the fuel-flowing section of the differential fuel pressure valve thereby to vary the fuel pressure difference across the fuel-metering orifice whereby the air-fuel ratio is varied when the engine operating condition is varied.
