Abstract
An apparatus and method for force feeding air to the carburetor of an internal engine. The apparatus includes a fitting for diverting a portion of the pressurized emission control air, the fitting positioned in the hose supplying pressurized air from an air pump of an emission control system to the exhaust system of a vehicle. The diverted air, after passing through an air filter, is introduced into the interior of the carburetor air filter housing radially inwardly from the air filter element within the housing. The pressurized air then flows through the carburetor to thereby enhance uniform distribution of the air-fuel mixture to the cylinders of the engine. Because the output of the air pump varies with the speed of the engine, higher pressure air is furnished at higher speeds of the engine. The furnished air can be pre-heated to further enhance vaporization of the fuel.
