摘要： A fuel supply system for supplying fuel and for satisfactorily preparing the fuel-air mixture fed to a mixture-compressing, spark-ignited internal combustion engine which comprises an arbitrarily operable throttle element arranged in the air intake manifold wherein fuel can be supplied upstream of this throttle element. The throttle element is mounted on a rocking lever connected to a bearing shaft arranged outside of the air flow at the air intake manifold and is displaceable in the opening direction during full load and at higher speeds against the force of a compensating spring until the throttle element comes into contact, with a full-load stop, with the rocking lever. During full load and at low speeds, the compensating spring displaces the throttle element in the closing direction so that a rather large pressure drop occurs at the throttle element so that an improved conditioning of the injected fuel is obtained. A resilient member, engaging via a compensating lever on the bearing shaft, serves to compensate for the opening moment effective at the throttle element due to the air pressure drop. The resilient member is under the effect, on the one hand, of the air pressure in the air intake manifold section downstream of the throttle element and, on the other hand, of the atmospheric pressure or the air pressure upstream of the throttle element with a resetting spring effective on the throttle element.

摘要： A fuel injection device increases an increment value of fuel after cut-off of assist air so that the air/fuel ratio for combustion can be held constant to stabilize the idling rotational speed. The device has control means for controlling, based on various detection signals indicative of an engine cooling water temperature, an engine rotational speed, an amount of intake air, etc., a valve-opening time of a fuel injection valve in accordance with a predetermined control program, and also controlling an on/off control valve for cutting off air supplied to fuel atomizing means. Fuel incrementing means increases an amount of liquid fuel supplied to the fuel injection valve depending on opening/closing of the on/off control valve and the temperature of engine cooling water. When the on/off control valve is closed and an engine is in a state of steady operation, the increment value of the liquid fuel supplied to the fuel injection valve can be gradually increased by the fuel incrementing means.

摘要： A fuel injection system which serves to supply fuel to a mixture-compressing, externally ignited internal combustion engine which includes an air flow rate member for actuating a metering and distribution valve, a flushing valve is disposed in an outlet line leading from each injection valve to a return flow line open when the engine is turned off and immediately after actuation of the ignition switch of the engine, enables a return flow via the outlet lines of the fuel flowing through the fuel supply line and the metering and distribution valve assembly to the injection valves until an electromagnetic valve drivable by a time control element opens a pressure line to a pressure chamber of the flushing valve, and the pressure prevailing in the pressure chamber opens a diaphragm connected to the movable valve parts of the flushing valve in such a manner that the flushing valve closes. Simultaneously with the opening of the electromagnetic valve, the electrical circuit of the starter motor is closed, so that after the preceding filling with fuel of all the lines and assemblies of the fuel injection system with fuel, a more certain start of the engine is assured.

摘要： A fuel-air proportioning and mixing system for internal combustion engines is disclosed comprising a variable orifice for measuring the volume of air and a motor driven variable volume displacement pump for measuring and atomizing fuel. Changes in size of the variable orifice in response to variations of air volume furnishes energy to modulate the fuel supply to predetermined ratios with continuous correction for air temperature, humidity, and barometric pressure. Electric motor also provides energy to atomize the fuel and mix it uniformly with air passing to engine intake manifold. The fuel-air ratio is controlled from the most economical to the most powerful in response to engine output load.A variation of the device to accommodate stratified charge engines provides two air fuel ratios -- an ideal mixture for ignition, and a lean mixture automatically variable with torque requirements for the main combustion charge.Other functions provided include automatic enrichment of mixture for cold starting, controlled deceleration of engine speed to prevent stalling, automatic enrichment of mixture if idle speed declines below a predetermined setting, curtailment of fuel supply while decelerating or coasting above a predetermined engine speed, and a complete cut-off of fuel supply with ignition to prevent dieseling. Since there is no float chamber, percolation and vapor lock are eliminated.
