AIR/FUEL RATIO REGULATOR ABSTRACT OF THE DISCLOSURE An air/fuel ratio regulator for control of the movement of a fuel flow control lever on a fuel injection pump. A lever is connected to the pump lever and moved by an aneroid to change the pump fuel flow as a function of engine manifold vacuum changes to maintain a constant air/fuel ratio to the mixture charge. A fuel enrichment lever moves to modify the movement of the fuel control lever 54 to compensate for changes in intake manifold gas temperature as sensed by a coil thermostat, to maintain the constant air/fuel ratio. A fuel enrichment shaft having a piston is connected to the enrichment lever and to a number of spaced,interconnected but relatively movable pistons that are adjustable to change the position of the enrichment lever and therefore the air/ fuel ratio as a function of exhaust gas recirculation back into the engine, and operating the engine at cruising con- ditions for an extended period, or operating the engine at idle speed, all with leaner air/fuel ratios. An infinite number of different air/fuel ratios can be established.
