AIR/FUEL RATIO REGULATOR 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 conditions 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. |
