An improved charge forming system for an internal combustion engine. Fuel and air are metered to the engine as functions of both operator control and manifested engine power output. The incremental changes in fuel flow and air flow which are effected as a result of changes in engine power output are unequal so that the total fuel-air mix ingested by the engine becomes leaner as engine power increases. When the fuel-air mixture becomes so lean that engine power decreases, the charge forming system enriches the mixture so that the system maximizes engine power for any given rate of fuel flow. In a presently preferred embodiment the fuel-air ratio supplied to the engine is leaner than the stoichiometric mixture.

A charge forming system for optimizing the air-to-fuel ratio of an internal combustion engine, comprising: control means for varying the flow of fuel and air to the engine; means adapted to be coupled to the engine for producing a manifestation of delivered engine power; servo means coupled to said control meaNs for progressively monotonically altering the air-to-fuel ratio of the charge delivered to the engine in response to a manifested change in delivered engine power at least until said manifested change ceases.
