Abstract
A fuel delivery control apparatus for use with an internal combustion engine for controlling the amount of fuel metered to the engine based upon engine operating conditions. A control unit is provided for calculating an acceleration enrichment related correction factor from a relationship programmed into the control unit to correct the amount of fuel metered to the engine so as to provide acceleration enrichment for a predetermined period of time after the engine acceleration starts. This relationship defines the acceleration enrichment related correction factor as a function of selected engine operating conditions. The relationship is corrected based upon recent engine operating conditions.
