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.

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： 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： 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 with a mouth piece in which a valve seat body is disposed, two magnet coils two cores and one armature, which has a spherical guide section and is connected to a valve needle. The spherical guide section is slidably supported with its circumference in a guide bore of the valve seat body and in its stroke movement away from the core is limited by a tapering stop opening which adjoins the guide bore. A plastic bushing is mounted on a guide step of the valve seat body and is pressed by a spring against the core end face, thereby preventing a dirct flow of fuel to the remnant air gap on the armature, as a result of which the depositing of soil particles in the gap is avoided.

摘要： A magnetic injection valve for injecting fuel into the intake tract of internal combustion machines, which is distinguished by particularly good internal cooling. A magnetic coil wound onto a coil carrier is located in the valve, being introduced into a valve housing and surrounds a ferromagnetic core. The core acts upon an armature which is connected to a movable valve needle. A bushing in the core and a sleeve located outside the core are arranged such that the fuel, emerging from an inflow tract of a supply device flows via the sleeve serving as a fuel line and reaches the interior of the valve housing that receives the magnetic coil; after flowing virtually completely around the magnetic coil, the fuel leaves this interior via a bore and flows back between the bushing and the core as far as the end of the bushing, and then flows on through the bushing to reach the armature to flow on to the valve seat. For better cooling of the magnetic coil, flow conduits are machined into the coil holder such that the fuel flow virtually surrounds the coil.

摘要： An electromagnetically actuatable valve which serves in particular to inject fuel into the intake tube of internal combustion engines operating with fuel injection systems. The fuel injection valve includes a valve housing, a shell core having a magnetic winding and a flat armature, which is firmly connected with a valve element which passes through a central guide opening in a guide diaphragm and cooperates with a fixed valve seat. The guide diaphragm has a fastening zone and together with the central guide opening cut out of a centering zone of the guide diaphragm guides the valve element in the radial direction toward the valve seat. The fastening zone is connected via struts with an annular guide zone on which the flat armature, under spring tension, rests with a concentric guide edge and is guided in a plane parallel to the end face of the shell core. The centering zone of the guide diaphragm is connected in turn via struts with the guide zone.

摘要： An electromagnetically actuatable valve which serves in particular to inject fuel into the intake tube of internal combustion engines operating with fuel injection. The fuel injection valve includes a valve housing, a shell core with a magnetic winding, and a flat armature which is firmly connected to a valve element having a tubular section and a spherical section. A guide diaphragm attached to the housing engages a guide edge of the flat armature in an elastic manner and guides the flat armature parallel to the end face of the shell core. The coaxial guidance of the spherical section relative to the valve seat is effected by means of guide faces of a guide ring. As a result, the movable valve element can have an elongated embodiment, and the fuel injection can be effected at any desired location of the intake tube, while the valve simultaneously requires little installation space.

摘要： A method for preventing damage to a temperature-dependent resistor disposed in a flow cross-section caused by overheating as a result of the ignition of a combustible, gaseous mixture during a burnoff process and an air flow rate measuring device for performing the method are proposed. The air flow rate measuring device includes a temperature-dependent resistor disposed in a bypass line. Deposits on the surface of the temperature-dependent resistor are removed in a burnoff process, preferably following the opening of the ignition switch. The danger then exists that if the device is used in a motor vehicle, combustible fuel-air mixture located in the vicinity of the temperature-dependent resistor may ignite, and the temperature-dependent resistor would thereby be destroyed because of overheating. For this reason, a slide member is pushed into the flow cross-section during the burnoff process, so that only a small combustible volume is available in the vicinity of the temperature-dependent resistor.
