ABSTRACT:
A fuel metering system controlling the mass fuel-air ratio in a spark ignition engine in response to fuel and air volume measurements. Linear responsive transducers respond to various temperatures, pressures, throttle positioning, fuel flow, air flow and engine operation for correcting the volume flow measurements of both fuel and air to mass flow measurements. A positive displacement, dual action pump delivers fuel to the throttle body of the engine in response to the mass of the air entering into the throttle body.
