ABSTRACT:
A control system senses air quantity entering an engine, and oxygen in the engine exhaust. A controller controls an amount of fuel injected into the engine according to the sensed oxygen level. As the car changes speed, air flow to the engine changes. The controller converts sensed air flow into an efficiency parameter, and compares it to a setpoint. When an air flow changes and the setpoint is reached, the feedback control operation is suspended, and the controller changes the I-gain in a series of gradually changing steps. The gradual change in I-gain accordingly changes the amount of fuel injected in a series of gradually changing steps.
