A charge forming system is disclosed which monitors a parameter of engine combustion efficiency, such as power output, and derives a signal indicating the sense of power change. A fuel mixture control system responds to an indication of increasing power to continually and progressively lessen the fuel/air ratio to attain the leanest possible mixture consistent with maximum instantaneous engine power output. In a preferred embodiment liquid fuel is vaporized before delivery to the engine combustion chambers, and a variable orifice provided to enhance the flow characteristics of the vaporized fuel.

A charge forming system for automatically and continually optimizing the fuel/air ratio of charge supplied to an internal combustion engine comprising: transducer means adapted to be coupled to the engine for outputting a first signal representing the instantaneous combustion efficiency of the engine, said transducer means including means for producing signals representing the rate of fuel flow and the engine power output; means for combining said signals to produce an output signal representing instantaneous combustion efficiency of the engine; and a charge control for changing the fuel/air ratio of the charge, including a servomechanism coupled to said transducer means and responsive to changes in the level of said first signal to decrease the fuel/air ratio of the charge when instantaneous combustion efficiency of the engine is increasing, and to increase the fuel/air ratio of the charge when the instantaneous combustion efficiency of the engine is decreasing.
