Abstract
An air-fuel ratio control system for an automobile engine including an intake passage having a throttle valve, and a fuel supply unit, which comprises an air detector for generating an air signal indicative of the quantity of air sucked to the engine through the intake passage, a throttle detector for generating a throttle signal indicative of the opening of the throttle valve, and a control unit operable in response to the signals from the air and throttle detectors for determining the air-fuel ratio of a combustible air-fuel mixture to be supplied to the engine in dependence on the amount of air sucked when a load on the engine is small, but on the opening of the throttle valve when the load on the engine is great.
