ABSTRACT:
A closed loop fuel control system for an automobile internal combustion engine, which derives a control signal indicative of the air-fuel mixing ratio and adapted to control the supply of a mixture of gasoline with alcohol to maintain the air-fuel mixing ratio at a stoichiometric value is used to control either the ignition timing or the rate of supply of exhaust gases being recirculated through the EGR system. This is applicable where as an automobile fuel, a mixture of air with blended fuel comprising, for example, gasoline and alcohol is used.
