ABSTRACT:
In order to obviate the delay between a demand for transitory engine operation and the injection of the appropriate amount of fuel, an initial correction pulse width is generated in response to the change in throttle valve position is added to a basic width which is developed based on the output of an air flow meter located in an upstream section of the induction conduit. The system further provides for continuously updating correction factors which are applied to the throttle sensor to ensure linearity and generating weighting factors and the like which are appropriately applied to improve the air-fuel control.
