摘要： An injection valve for preparing fuel injected into an intake tube of an internal combustion engine and an injection valve for performing the method are proposed. The injection valve includes a movable valve element, which cooperates with a fixed valve seat, downstream of which the fuel reaches fuel guide bores inclined relative to the valve axis and this fuel discharges into a preparation bore at a distance (a) on the bottom from the wall. The fuel flowing via the fuel guide bores at first exits freely from the discharge openings of the fuel guide bores into the preparation bore and subsequently arrives at the wall of the preparation bore, from where it flows in the form of a film, distributed over the wall, toward the open end of the preparation bore and is ejected into the aspirated air of the internal combustion engine.

摘要： A fuel injection system for internal combustion engines is proposed which serves the purpose of fuel injection into the air intake tube of the engine. The fuel injection system includes a fuel injection valve, which is supported upstream of a throttle valve in a holder body disposed coaxially in the air intake tube. A fuel supply line leads to the fuel injection valve, extending in a downwardly directed manner toward the fuel injection valve and away from a deaeration chamber. A fuel return line leads away from the fuel injection valve, extending in an upwardly inclined direction to discharge into the regulating chamber, disposed at a higher level, of a pressure regulating valve. A fuel feed line originating at a fuel supply pump terminates in an upwardly directed manner into the dearation chamber, which communicates via a dearation nozzle with the regulating chamber, so that vapor bubbles can escape upstream of the injection valve into the return side of the injection valve.

摘要： An electromagnetically actuatable valve, especially an injection valve for fuel injection systems which supply internal combustion engines with fuel, is proposed in which the fuel injection valve encompasses a valve chamber and a core upon which a magnetic coil is mounted by means of a carrier body. Fuel supply openings discharge into a flow passage provided around the magnetic coil. Vapor bubbles dissolved in the fuel may be flushed out of the flow passage via a first restriction into fuel return openings which communicate with a fuel return line. On the other hand, the fuel may flow from the flow passage into the collecting chamber which houses a valve component and a valve seat. Vapor bubbles which may appear near the valve component may be flushed out via a second restriction which is provided in the interior of a core to reach the fuel return openings. Thus, disturbances with fuel injection, especially during the "hot start" of the internal combustion engine, are avoided.

摘要： A mixture formation system is proposed for mixture-compressing internal combustion engines with externally supplied ignition. The mixture formation system includes an air intake fitting in which an electromagnetically actuatable injection valve is held concentrically, upstream of a throttle valve. Disposed upstream of the injection valve is an air flow rate meter provided with a temperature-dependent resistor. The electronic regulating device of the air flow rate meter and a pressure regulator for regulating the fuel pressure at the injection valve as well as a supplementary air valve for controlling an air bypass bypassing the throttle valve during the warm-up phase of the engine may be provided on the air intake fitting. As a result, a mixture formation system is attained which is simply constructed and functions reliably, and which because of its compact structure can be accommodated in the engine compartment of an internal combustion engine even where space is extremely limited.

摘要： A fuel injection valve and a method for the automatic establishment of the desired armature stroke of the fuel injection valve are proposed which serves the purpose of injection at low fuel pressures into the intake tube of a mixture-compressing internal combustion engine with externally-supplied ignition. The fuel injection valve includes a magnetic coil surrounding a core and a flat armature guided by at least one guide diaphragm held on its outer circumference, which is firmly connected with a movable valve element cooperating with a fixed valve seat. The fuel delivered via a fuel inlet nozzle can proceed through apertures and recesses in the guide diaphragms past the valve seat to a fuel discharge nozzle by way of which a portion of the delivered fuel can flow back again into a fuel return line. Via an annular channel the fuel stream exiting from the nozzle bore can be prepared with air which surrounds the fuel stream.

摘要： An electromagnetically actuatable fuel injection valve which serves to supply fuel to a mixture-compressing internal combustion engine having externally supplied ignition. The fuel injection valve includes a valve housing having an outlet tube in which a valve seat body is disposed. Respective magnetic coils are disposed on pole pieces and a permanent magnet is disposed between the pole portions of the pole pieces. In the valve seat body a flow bore is provided, which merges via a stop face with a guide bore, in which a ball-shaped armature is slidably disposed. A valve needle which is joined with the armature protrudes through the flow bore and, with a closing head, cooperates with a valve seat in the valve seat body. Directly upstream of the closing head a metering collar is provided on the valve needle, an annular metering gap being formed between the metering collar and the wall of the flow bore. The valve needle is supported in pendulum fashion in the flow bore via the ball-shaped armature and, when the valve is opened, it is centered in the flow bore by the fuel flowing therein.

摘要： A fuel injection system for injecting fuel into the air intake tube of an internal combustion engine, including at least one fuel injection valve, which is disposed in a holder body and communicates with a fuel supply line and a fuel outflow line. The fuel injection valve is provided with a fuel supply groove, branching off from which are fuel inlet openings, and a fuel outflow groove, leading away from which are fuel outlet openings. The fuel injection valve is guided in the radial direction in a guide opening of the holder body by supporting bodies of a fuel filter which extends axially over the fuel injection valve, covering the fuel supply groove and the fuel outflow groove. The middle supporting body of the fuel filter is embodied such that it seals off the fuel supply line and the fuel supply groove from the fuel outflow line and the fuel outflow groove. In order to carry away vapor bubbles, there is either a degassing conduit embodied on the fuel injection valve between the fuel supply groove and the fuel outflow groove, a degassing conduit embodied on the middle supporting point, or a degassing conduit embodied on the holder body.

摘要： An electromagnetically actuatable fuel injection valve which has an internal scavenging system for cleaning dirt particles from a magnetic field air gap. A portion of the fuel flowing in via an inflow line and an inflow opening reaches the vicinity of an air gap defined on one side by an armature and on the other by magnetic poles and flows through this gap, and then flows via an outflow opening to enter an outflow line that communicates with a fuel return. As a result of the described scavenging of the air gap, dirt particles are prevented from becoming firmly attached there and causing impairment of the performance of the fuel injection valve.
