摘要： An adaptive charge forming system for an internal combustion engine is disclosed which monitors a parameter of engine combustion efficiency, such as power output, and derives a signal indicating the direction and amplitude of power change. The fuel mixture control system responds to changes in power output, regardless of their source, to maintain the engine air/fuel ratio in a preferred region. In a preferred embodiment, engine crankshaft angular acceleration is monitored to maintain the air/fuel mixture at the lean limit. A stepping motor is used to control a value for bleeding additional air into the charge; a clock provides steady pulses to the motor, tending to lean the mixture, while enrichment is effected upon the detection of each weak combustion event. The clock frequency thus sets the equilibrium rate of weak combustion events, defining the optimal mixture to be supplied to the engine.

摘要： A combined fuel vapor injector and igniter system for internal combustion engines and method of operating the engine therewith in which liquid fuel enters an injector-igniter device, is vaporized using the engine's heat of combustion, and exits in vapor form into the engine combustion chamber where it mixes with air or an air-fuel mixture which has entered through an intake valve, or port, and the resulting air-fuel mixture is ignited. The system assures reliable ignition, so that engines may be run at leaner than stoichiometric air-fuel ratios to take advantage of increased fuel economy, and reduced emissions of the oxides of nitrogen hydrocarbons and carbon monoxide. Power output equalization is attained between cylinders.

摘要： 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.

摘要： 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.

摘要： A bistable fluidic switch is switched from its stable state by a pin inserted in the power nozzle of the bistable fluidic switch, the pin being controlled by an electromagnetic actuator which is controlled from an electronic computer. The fluidic switch element has a cross-over type interaction region and a common outlet leading to a pair of output passageways, one of which returns fuel to the supply tank, and the other of which leads to the air intake manifold of the engine. Air is introduced into the output passageway leading to the engine so as to air atomize the fuel before injection of same into the air intake manifold.

摘要： An adaptive charge mixture control for an internal combustion engine includes four input signals supplied to an OR gate to generate a net "go rich" signal supplied to a servo motor controlling an air/fuel charge mixture control valve for an internal combustion engine. The servo is also supplied with a "go lean" fixed signal tending to lean out the air/fuel mixture. The four "go rich" signals include a first signal derived from a comparison of engine speed with a predetermined minimum (i.e., idle) level; a second signal derived from comparing throttle positions with a preset minimum throttle position; a third signal derived from comparing engine deceleration rate with a preset engine deceleration rate; and a fourth signal derived from a measurement of engine instantaneous power output.
