Abstract
An automobile air-fuel control system is incorporated with an altitude compensator in order to minimize an excessive enrichment of an air-fuel mixture which would occur when the engine is operated at a high altitude under a high load operating condition. This altitude compensator is constituted by a delay circuitry operable to delay the timing at which the supply of bleed air for leaning the mixture is interrupted when the engine is operated at a high altitude under the high loaded condition.
