ABSTRACT OF THE DISCLOSURE Fuel control apparatus for dual chamber stratified charge engine systems utilizes a single point fuel control arrangement for the main (lean) air-fuel mixture in combination with a multi-point fuel injection arrangement for the igniting (rich) mixture. The single point and multi-point arrangements may be essentially independent in that they both sense and compute quantity of air flow, respectively, and meter and inject fuel respectively. In an alternate form of the invention, the air flow sensing function of the single point arrangement is used to provide suitable air flow information to the multi-point arrangement and in another alternate form of the invention the fuel flow injection function of the multi-point arrangement is used to provide suitable fuel flow information to the single point arrangement. The alternate forms of the invention reduce the overall complexity of the combined system by interrelating the single point and multi-point arrangements, thereby eliminating component and functional duplicity.
