Closed loop fuel control system with air/fuel sensor voting logic
Patent
·
OSTI ID:6800466
In a closed loop air and fuel ratio controller for an engine, an air/fuel sensor is responsive to the engine exhaust gases to provide a signal representing the air/fuel ratio of the mixture supplied to the engine. The output of the sensor is sampled N times during each of successive sampling periods and the number of samples indicative of a rich mixture versus the number of samples indicative of a lean mixture is utilized to provide an output representing a rich or lean error input to the closed loop controller.
