    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 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 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: 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: What follows is a description of a fuel injection system for spark plug-ignited internal combustion engines with compression of the air-fuel mixture and structure for controlling the system pressure. The system is one which includes a device for regulating a fuel injection quantity operating in dependence on the air quantity streaming through a suction tube of the engine, a pressure regulator for determining normal system pressure, injection nozzles which have an opening pressure lower than the system pressure, a continuously delivering fuel pump, and the structure identified above. This structure adjusts the device for regulating the fuel injection quantity so that the starting pressure in the system is retained below the opening pressure of the injection nozzles and above the vapor pressure of the fuel until a quantity of fuel sufficient to replace the quantity of fuel evaporated or leaked due to a temperature gradient in the system resulting from engine cut off has been restored.

    摘要: An electromagnetically actuatable valve which serves as a fuel injection valve for fuel injection systems in internal combustion engines. The valve includes a valve housing as well as a magnetic coil with poles serving as the core, with which an armature cooperates, which is connected to a valve element the sealing element of which cooperates with a valve seat in a valve seat body. The valve element protrudes without contact through a throttle bore in the valve seat body with a throttling element and is held in a sealing manner on the valve seat by the armature when the magnetic coil is excited. When the magnetic coil is not excited, the valve element is moved by the pressure forces of the fluid in the opening direction of the valve and is centered by the fluid flow.

    摘要: A fuel injection valve which serves to inject fuel in an internal combustion engine. The fuel injection valve includes a nozzle holder in which a nozzle body having an injection port is disposed. The injection port is opened by a closing body movable counter to the force of a closing spring in order to eject fuel. A gas guidance sheath encompasses the nozzle holder with a cylindrical portion and the nozzle body with a bottom portion and has at least one axially extending gas guidance conduit communicating with an air source. The gas guidance conduit leads to a gas ring conduit in the bottom portion. The nozzle step protrudes through the bottom portion and with the passageway opening thereof forms a throttling gas ring gap immediately above the injection port, so that fuel emerging from the injection port can immediately be enveloped by gas, such as air or exhaust gas, and thereby prepared.
