A method and apparatus for regulating the fuel supply of internal combustion engines having carburetion, specifically the richness of the air-fuel mixture, as a function of engine speed and atmospheric pressure. The richness is controlled by a supply of pressurized air downstream from the carburetor in the intake manifold, which is controlled in a self-evident manner by a bellows and by the amplified pressure at the carburetor venturi. Application to internal combustion engines with carburetors using a pump supplying pressurized air for anti-pollution purposes is intended.
