  • Control method and apparatus for adaptively determining a fuel pulse width
    Patent number: 6644291
    Abstract: A control system for controlling an engine (10) of an automotive vehicle has an air charge sensor (47) generating a first signal indicative of an air charge, a purge flow valve (74) generating a second signal indicative of purge flow. A controller (42) is coupled to the air charge sensor and the purge flow valve. The controller (42) is configured to determine a first amount of fuel to deliver to the cylinder based on the first signal and a desired air-fuel ratio. The controller is configured to calculate a first air-fuel ratio change value based on the first signal and is configured to calculate a second air-fuel ratio change value based on the second signal. The controller is configured to deliver a second amount of fuel to the cylinder based on the first amount of fuel and the first and second air-fuel ratio change values.
