ABSTRACT:
A heat-type flow sensor is provided on the upstream side of a Venturi portion formed in an air-intake path and in an air bypass communicating with the Venturi portion. An electromagnetic device is provided to control the amount of air flowing in the air bypass so that the output of the heat-type flow sensor converges to a set level. This electromagnetic device drives a fuel-scaling valve to scale fuel in accordance with the change of the amount of air supplied to the engine, and this scaled fuel is continuously injected into the air-intake path.
