摘要： A fuel injection nozzle for internal combustion engines, provided with a valve needle and an induction coil, which sits in a spacer plate mounted between the nozzle body and the nozzle holder. The valve needle projects into the induction coil and acts upon the magnetic domain of the induction coil by the action of its movement, whereby a signal dependent on the velocity of the needle is produced. The induction coil is provided with laterally disposed contact prongs which are connected with extended connecting wires by means of a weld or solder joint. The connecting wires lead through boreholes in the nozzle holder. The injection nozzle is distinguished by an especially small electrical line resistance, and by the fact that, with appropriate dimensioning and construction of the ends of the connecting wires, which carry the extended connection contacts, there will be no special contact measures necessary for disassembly.

摘要： A fuel injection nozzle is proposed, intended in particular for Diesel engines, in which an induction coil is installed in an intermediate disc. The coil core is embodied by a pressure element and a valve needle in force-locking contact therewith. An annular permanent magnet is secured either on the pressure bolt or on the intermediate plate. This embodiment of an injection nozzle, as a so-called needle stroke transducer, is used when it is desired to ascertain the duration of injection and especially the onset of injection.

摘要： A fuel injection pump for internal combustion engines having a hydraulic control mechanism includes a control cylinder with a control piston actuating a control member, a hydraulic work chamber and one switching valve each for an input and an output controlled by a valve control unit. The inflow to and return from the work chamber is provided with the control valves in order to shut down the engine upon a shutoff or a malfunction in the hydraulic control mechanism. The fuel feed pump is electrically driven, and the hydraulic work chamber communicates with the fuel tank via a relief device. The supply of current to the valve control unit and the feed pump is switched on and off, along with the rest of the current supply to the engine, via a driving switch. Additionally, the valve control unit is embodied such that upon the appearance of a persistent control deviation of the control member, the valve control unit shuts off the feed pump. The relief device includes various variant embodiments operative upon shutoff of the current supply or the occurrence of a malfunction and enables the restoration of the control mechanism to its zero or stopping position.

摘要： A nozzle holder for internal combustion engines is proposed, in which a sleeve can be secured in the cylinder head by means of a tightening nut. The sleeve protects the portion of the nozzle which protrudes into the combustion chamber from thermal effects. Ease of serviceability is attained in that when the nozzle holder is rotated out of the cylinder head, the sleeve is simultaneously removed, without requiring additional hand operations.

摘要： A fuel injection pump for internal combustion engines, in particular an in-line injection pump for Diesel engines, is proposed having an injection quantity governor and an electrically driven feed pump, in which in order to assure an emergency shutoff in the event of a malfunction of the injection quantity governor, a check valve, the forward flow direction of which is toward a suction chamber filled with fuel by the feed pump, is disposed between the pressure-side outlet of the feed pump and the suction chamber. An emergency shutoff device responding to a malfunction switches off the feed pump drive, so that because of the lack of feed pressure the check valve closes and blocks off the suction chamber. The engine comes to a stop, as soon as a partial vacuum is established in the suction chamber, which occurs as soon as several revolutions later.

摘要： A fuel injection device for mixture compressing, externally ignited internal combustion engines, which serves to meter the fuel proportional to the intake air and aspirates the air-fuel mixture. The fuel injection device includes an air flow rate meter located downstream of a butterfly valve in the air induction tube. The bearing shaft of the air flow rate meter includes a fuel metering valve which can be activated directly by the air flow rate meter. To correct the air-fuel mixture because of air density downstream of the butterfly valve, the fuel injection device is so arranged, that when the butterfly valve is in its idling and full load positions a rich air-fuel mixture can be regulated, and when the butterfly valve is in a partial load position a lean mixture can be regulated.

摘要： A regulating device used with the fuel injection system of an internal combustion engine, for regulating the proportions of the operating mixtures of the engine. The regulating device is embodied as a pump which is incorporated into the existing fuel injection system. The pump has a chamber within which a piston is displaceable. This piston is coupled with the fuel rate adjusting member of the fuel injection pump of the fuel injection system, and is displaced in accordance with the adjusted position of the fuel rate adjusting member. The pump is also connected with the throttle plate of the fuel injection system located in the induction tube of the engine. By reason of these connections, rapid adjustment movements of the fuel rate adjusting member can be effectively translated to a proper adjustment of the throttle plate without the delay found in presently known regulating devices.
