Abstract
A method and apparatus for the control of the air-fuel ratio of a mixture to an internal combustion engine. A value of fuel-delivery requirement for the engine is determined based upon engine load. An engine crankshaft position at which the pressure in each cylinder is at maximum is detected during each data sampling cycle. The determined fuel-delivery requirement value is modified based upon the detected engine crankshaft position.
