ABSTRACT:
An arrangement for the preparation of the fuel-intake air mixture for an internal combustion engine includes an idle fuel nozzle located in the engine induction manifold. Additional fuel nozzles, located in the intake air passage, are operable to supply fuel during other portions of the operating range. The fuel air mixtures formed by the arrangement are passed at speeds approaching sonic velocity to obtain a highly desirable mixing thereof.
