Patent
·
OSTI ID:5681976
The invention provides a method of, and apparatus for, controlling the fuel to air ratio of the fuel mixture to an internal combustion engine which includes a fuel mixture feed system having a known type of carburetor. In the method the fuel mixture is supplemented with air and exhaust gas by utilizing pressure controlled air and exhaust gas valves operated by pressure changes in the fuel feed system and/or intake manifold of the engine so that the valves open when the fuel to air ratio of the fuel mixture supplied by the carburetor is in excess of a predetermined value.
