  • Engine fuel mixture control system
    Patent number: 4301779
    Abstract: An internal combustion engine fuel mixture control system is provided for use with an engine having a fuel supply and an intake air supply connected to the engine wherein the fuel and air mix to provide a combustible fuel/air mixture for the combustion engine. A fuel flow sensor is connected to the fuel supply line for the engine while an air flow sensor is similarly connected to the air intake of the engine and the outputs from the sensors are fed to a proportionator which provides an output signal representative of the instant fuel/air ratio for the engine and this output is coupled to one input of a differential amplifier. The other input of the differential amplifier is connected to a fuel/air ratio reference so that the output from the differential amplifier is representative of the difference between the reference and the actual fuel/air ratio for the engine. The output fromm the differential amplifier is used to vary the fuel flow to the engine.
