ABSTRACT:
An electronic controller for an internal combustion engine provides a ratio control signal corresponding to a respective air/fuel ratio, and responds to an air flow signal, a fuel flow signal and the ratio control signal to control fuel flow as to make the ratio of air flow to fuel flow substantially equal to said respective air/fuel ratio. The ratio control signal is developed from a base run ratio control signal as modified in response to various parameters such as engine temperature, manifold pressure, idle, manifold vacuum, fuel temperature, wide open throttle, engine speed, and start. The controller also provides a speed-up circuit for promptly responding to change in air flow and dynamic braking for the fuel metering pump. The pump speed circuit includes a range extender. The controller further provides a timing advance control signal in response to air/fuel ratio and various engine parameters such as engine speed, manifold pressure, throttle position, engine temperature, air temperature, air/fuel ratio, and start.
