ABSTRACT:
A charge forming system for metering vaporized liquid fuel to an internal combustion engine. Liquid fuel is metered to a vaporizing chamber which is heated by the exhaust gases of the engine. Within the chamber the liquid vaporizes and expands rapidly, whereupon it is delivered to the intake ports of the engine to be mixed with air in the manifold or cylinders. The amount of fuel and air admitted to the engine is varied as function of both foot pedal position and developed engine power. The fuel-to-air ratio of the mixture provided to the cylinders is decreased as developed engine power increases. In a preferred embodiment additional fuel vapor is supplied to each combustion chamber by means of fuel vapor injectors, the net mixture supplied to the cylinders being leaner than the stoichiometric ratio. A feedback system monitoring selected engine parameters serves to vary the rate at which air is admitted to the engine, and an adjustable mechanism is provided to further adjust the proportions of the fuel-to-air ratio.
