摘要： A fuel injection system for supercharged internal combustion engines is proposed, which serves to meter a quantity of fuel adapted to the quantity of air aspirated by the engine and also serves to regulate the fuel-air mixture in accordance with operating characteristics of the engine. The fuel injection system includes an air flow rate member, the restoring force of which is generated by means of pressure fluid in a control pressure line. The pressure of the pressure fluid in the control pressure line is variable in accordance with at least one pressure control valve, by means of which the pressure in the control line and thus the restoring force exerted upon the air flow rate member, which actuates a control slide of a metering and distribution valve assembly, can be reduced when the intake tube pressure downstream of a compressor increases. The result is that an undesirable leaning down of the fuel-air mixture caused by the error in air density can be corrected.

摘要： A diaphragm valve which may serve as an equal pressure valve or as a pressure equalizing valve of a fuel metering and distributing unit for an externally ignited internal combustion engine. The valve has a flexible diaphragm having a clamped diameter and a pocket in the diaphragm supports a valve plate. The valve plate operatively cooperates with a valve seat of the valve and has an annular recess arranged to receive a spring to center the valve plate. The valve also includes a stationary thrust plate which is concentrically disposed relative to the valve seat, which defines a knife-shaped edge which lies in a common plane with the valve seat and which operatively cooperates with the valve plate. The knife-shaped edge is penetrated by a plurality of radially extending means defining openings therein.

摘要： A fuel injection system is proposed which brings about an improvement in the acceleration behavior of an internal combustion engine. The fuel injection system includes metering valves actuatable by means of an air flow measuring device, at which valves a pressure difference can be held constant via control valves and the pressure difference is variable in accordance with operational characteristics of the engine. To this end, the control valves are located on a control pressure line in which a control throttle and an electromagnetic valve are disposed. At the same time, pressure limitation elements communicate with the control pressure line and, in the event of acceleration of the engine, reduce the extent of increase of control pressure and thus assure fuel metering corresponding with the operational state of the engine.

摘要： A fuel injection system for substantially continuous injection into a suction tube of a mixture-compressing, spark plug-ignited internal combustion engine includes a fuel line and a fuel pump. A measuring member and an arbitrarily actuatable throttle flap are disposed, one behind the other, in the suction tube. The measuring member is displaceable in proportion to air quantity and against a resetting force which is normally constant but which is changeable in dependence on engine parameters. A metering valve having a movable part is disposed in the fuel line and coupled to the measuring member. The measuring member actuates the movable part for metering fuel quantity in desired proportion with respect to air quantity. A regulating mechanism, which includes a piston, is actuated in dependence on fuel pressure prevailing downstream from the fuel pump. The piston acts against the force of a spring.

摘要： A fuel injection system which serves to adapt the fuel-air mixture accurately over a wide range to operating conditions of the internal combustion engine. The fuel injection system includes metering valves, with each of which a regulating valve is associated, the movable valve element of which can be acted upon on one side by the fuel pressure downstream of the particular metering valve and on the other side by the pressure in a differential pressure control line, which is defined on one end by a first electrofluidic converter of the nozzle/baffle type and on the other end by a first throttle. The first electrofluidic converter is triggerable in accordance with operating characteristics of the engine and determines the pressure in the differential pressure control line and thus, via the regulating valves, the differential pressure at the metering valves. The control slide of the metering valves protrudes with one end face into a pressure chamber, which communicates with a restoring force pressure control line in which the pressure, and thus the restoring force exerted upon the control slide, is variable by means of a second electrofluidic converter, which communicates via an uncoupling throttle with the fuel supply line.

摘要： The control pressure valve assembly for a fuel injection system of an internal combustion engine provides variable fluid pressure which provides a restoring force against the fuel control plunger to alter the fuel-air ratio in dependence on engine and environmental variables. In particular, the fluid pressure is regulated by a spring loaded diaphragm valve which is also subjected to a variable closing force provided by an air pressure cell and by a first temperature sensitive element which opposes the forces of the spring and of the air pressure cell to provide decreased fluid pressure at low engine temperature and a second temperature-sensitive element to oppose the force of the air pressure cell only below a predetermined temperature.

摘要： A fuel injection system for externally ignited internal combustion engines in which a fuel metering and distributing valve is controlled by an air sensing element disposed in the air suction tube of the engine and by structure which is adapted to alter the restoring force exerted on the air sensing element through the fuel metering and distributing valve. The noted structure includes a control pressure conduit, a pressure control valve connected to the control pressure conduit, a second conduit for connecting the pressure control valve to the suction tube of the engine downstream of the butterfly valve, and a third conduit for connecting the pressure control valve to the atmosphere or to the air suction tube downstream from an air filter. With this structure it is possible to alter the restoring force mentioned above so that an enriched fuel-air mixture is achieved when the butterfly valve is opened to its full load position, and so that a leaner fuel-air mixture is achieved when the butterfly valve is closed to a partial load position.

摘要： A method and a fuel injection system for supplying fuel to a mixture-compressing internal combustion engine having externally supplied ignition is proposed. The fuel injection system includes metering valves, downstream of which regulating valves are disposed and at one side of which the fuel pressure downstream of the metering valves prevails and on the other side of which the fuel pressure in a control pressure line prevails. The control pressure line communicates with the fuel supply line and is limited by a control throttle and a return-flow throttle; from it, a branch line leads to an electromagnetic supplementary injection valve, by way of which further fuel, in addition to the fuel injected via injection valves, can be injected. The triggering of the supplementary injection valve can be effected by an electronic control unit for injecting fuel during cold starting of the engine or in the presence of a measurement signal characterizing an acceleration of the engine. By means of the triggering of the supplementary injection valve, the pressure in the control pressure line is reduced, as a result of which--because of an increase in the pressure difference at the metering valves--a greater fuel quantity is metered.

摘要： A fuel injection system is proposed which can be triggered such that when control signals characterizing engine overrunning are present, fuel injection is interrupted. To this end a pressure relief valve is provided, which opens in the presence of control signals characterizing engine overrunning and lowers the fuel pressure upstream of the fuel metering locations and accordingly upstream of the injection valves as well to below the opening pressure of the injection valves, so that no further fuel is injected via the injection valves during engine overrunning.

摘要： An apparatus is proposed which serves to control the position of a throttle device disposed in the intake tube of an internal combustion engine. The apparatus includes a lever, which is joined to a shaft of the throttle device and has both a stop screw arranged to cooperate with a stop and an adjusting screw arranged to cooperate with a feeler pin. The feeler pin traces the position of a control body provided with a cam track and the control body can be displaced to a variable extent in a guide bore by means of an expansion element and thereby bring about a variably large rotation of the throttle device and hence a variably large opening of the cross section for the aspirated air during engine idling in the warm-up phase.
