Abstract
A fuel supply control system for an automobile engine comprises a detector for detecting change in engine operating condition, a fuel adjuster for variably controlling the amount of fuel to be supplied to the engine, an A/F ratio setting device for setting the lower or higher A/F ratio of a combustible mixture than the critical A/F ratio to a higher or lower A/F ratio than a critical A/F ratio at which the engine can produce substantially the same or intermediate torque as that produced by the same engine with the supply of such combustible mixture, and a control operable in response to an output from the detector to control the fuel adjuster in such a way that, at the time the engine is desired or required to be switched from one engine operating condition to another, the A/F ratio lower or higher than the critical A/F ratio can be rapidly adjusted to the higher or lower A/F ratio set by the A/F ratio setting device and, thereafter, the A/F ratio can be progressively adjusted to a target or desired value.
