摘要： A fuel injection valve is proposed which, especially in low-fuel-pressure systems, serves to inject fuel into the intake tube of a mixture-compressing internal combustion engine with externally supplied ignition. The fuel injection valve includes a fixed valve seat cooperating with a movable valve element, downstream of which the fuel to be injected is carried into a mixture guidance channel of a mixture guidance tube and surrounded on all sides with air or exhaust gas for preparation immediately upon its entrance into the mixture guidance channel and injected via an injection opening into the intake tube. The mixture guidance channel may be embodied as tapering in conical fashion toward the injection opening. For the purpose of preliminary preparation of the fuel, secondary air or exhaust gas can already be delivered to the fuel before its entrance into the mixture guidance channel. The fuel injection valve embodied according to the invention assures optimal preparation of the fuel to be injected, even at low fuel pressures, and good running behavior of the engine in the event of abrupt changes in load.

摘要： A fuel injection system for internal combustion engines having a multiplicity of injection valves which serves to provide fuel supply is proposed. The fuel injection system includes a common, rigid fuel line, having plug nipples into which the injection valves associated with the individual cylinders of the engine can be inserted in a sealing manner. The fuel line comprises one fuel distributor line and one fuel return flow line located one above the other. Each injection valve has one inlet stub and one outlet stub disposed concentrically relative to one another, protruding into the plug nipple in such a manner that the inflow stub communicates with the fuel distributor line and the outflow stub communicates with the fuel return flow line. As a result, not only is it possible to provide simple sealing toward the outside between the injection valve and the plug nipple but also rapid assembly of the fuel injection system is assured.

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 valve is proposed, which serves in particular to inject into the intake tube a mixture-compressing internal combustion engines with externally-supplied ignition. The valve includes a flat armature which is firmly connected with a ball arranged to cooperate with a fixed valve seat. The flat armature is pivotably supported on its end remote from the valve seat on a spring tongue preferably embodied out of a remnant air disc. A tubular inflow stub is disposed concentrically to the valve axis, communicating on one end with a fuel distributor line and on the other end protruding as deeply as possible into the valve. A tubular outlet stub leading away from the valve seat is concentrically guided in the inlet stub, and arranged to have its end remote from the valve seat discharge into a fuel return flow line. As a result, a cooling of the valve and the return of heated fuel which contains vapor bubbles to its supply source is assured.

摘要： A fuel injection apparatus for externally ignited internal combustion gas engines is proposed. The fuel injection apparatus comprises an intake pipe in which an air flow meter and a throttle valve are provided. The fuel quantity injected into the intake pipe via an injection valve is controlled by the air flow meter. To prepare the combustible mixture of injected fuel and air, a preparation air line branches off from the intake pipe between the air flow meter and the throttle valve. This preparation air line discharges into the injection valve. A throttle is provided in the preparation air line. A full-load air line discharges into the preparation air line between the throttle and injection valve. A shut-off valve is provided in the full-load air line, said shut-off valve being completely open at least during the full-load operation of the combustion engine, allowing additional air flow into the preparation air line, which air is drawn from the intake pipe upstream of the air flow meter.

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 fuel injection system is proposed which serves to supply fuel to a mixture-compressing, externally ignited internal combustion engine in accordance with operational parameters of the engine. The fuel injection system includes a metallic fuel distributor tube, which communicates via at least one branch line with at least one fuel injection valve, wherein the branch line is embodied as a metal tube and is connected with the fuel injection valve by means of a threaded assembly. The material used for the branch line is easily bendable metal. Between the threaded assembly at the branch line and the fuel injection valve, a thin-walled metallic bellows is provided, by means of which a lateral displacement between the attachment point of the branch line at the fuel distributor tube and the installation point of the fuel injection valve is compensated for, and the noise of operation produced by the fuel injection valve is damped.

摘要： A method for mixture formation for mixture-compressing internal combustion engines having a turbocharger and a fuel supply system for performing the method. The fuel supply system serves to regulate the fuel-air mixture in accordance with operating parameters of the engine and includes a first fuel supply element disposed upstream of a throttle valve and a second fuel supply element disposed upstream of a compressor. Below the operating temperature of the engine, fuel is fed only via the first fuel supply element. Above the operating temperature of the engine, the feeding of fuel is effected via the first fuel supply element until such time as the charging range begins, at a predetermined intake manifold pressure (p.sub.um), and above this pressure only via the second fuel supply element. The transition from one fuel supply element to the other takes place in accordance with a predetermined timed function. As a result, good fuel preparation and good cylinder filling are attained.
