ABSTRACT:
An air/fuel ratio control for an internal combustion engine which adjusts the fuel supply amount in response to correction factors dependent upon altitude and engine speed and altitude and engine load. In this way, it is not necessary to provide over-enriching of the fuel/air ratio to avoid over-heating when high altitude or low atmospheric pressure conditions prevail.
