摘要： A fuel injection pump of the distributor type in which a pump piston is driven to reciprocate and rotate simultaneously, thereby acting as a distributer. For fuel injection quantity regulation, an annular slide that is displaceable on a pump piston is provided, by way of which the pump work chamber can be relieved. To attain a low injection rate in the idling range, in addition to a first outlet opening, controlled by an upper edge of the annular slide, second outlet openings axially offset from the first are provided, for a relief conduit of the pump work chamber which cooperate with a radial control opening, which communicates with the pump suction chamber and is disposed in the wall of the annular slide. In the opening direction of this control opening, a groove provided with a throttle is provided, by way of which during idling operation, prior to the opening of the first relief opening, fuel can flow out of the pump piston in order to decrease the pumping rate of the pump piston. For higher load ranges, the control opening is moved out of the operative range of the groove which is effected by rotating the annular slide or interrupting the communication of the control opening with the suction chamber.

摘要： A fuel injection pump for internal combustion engines is proposed having a hydraulic instant-of-injection adjuster, which is exposed to an rpm-dependent pressure formed with the aid of a pressure control valve; the control of the pressure control valve is effected by means of variations of the control pressure acting upon it. This control is accomplished with the aid of at least one electrically controlled valve which is controlled by a control device in accordance with operating parameters. In this cost-efficient manner, the correct adjustment of the instant of injection can be established very precisely over the entire operating range of the engine, including the warm-up phase, at varying operating conditions.

摘要： A fuel injection pump for internal combustion engines is described, which for controlling fuel quantity is provided with control unit that controls an electric final control element, which in turn actuates the regulating member that determines the fuel injection quantity per pump piston supply stroke. The supply of fuel to the pump work chamber is effected from a fuel supply chamber, which is kept at a controlled pressure by a fuel feed pump. To limit the maximum speed of the engine supplied by the fuel injection pump in the event of failure of the control unit, a valve is provided in the intake line of the fuel feed pump. Using this valve, the flow cross section of the intake line can be varied or closed. By means of the modification of the fuel pressure in the fuel supply chamber effected thereby, a control of the fuel injection quantity that is not dependent on the position of the quantity-determining member is attained.

摘要： The injection pump includes a pump cylinder, a pump piston moving into it and a hydraulic device for adjusting the instant of injection. The adjusting device has an adjusting cylinder, which is directed parallel to the pump cylinder and is accommodated in the housing of the injection pump, and adjusting piston and a restoring spring and adjusts a control sleeve, which opens the pump piston provided with at least one control recess in the longitudinal direction of the pump piston. This orientation and disposition of the adjusting cylinder effects a space-saving and inexpensive design of the injection pump and improves the precision of adjustment. The adjusting piston and the control sleeve may be directed coaxially and embodied as a single component, as a result of which a further space saving and increase in adjustment precision are attained.

摘要： In a device for temperature responsive switching of overflow fuel quantities from a diesel fuel injection pump to a fuel supply tank or a filter of a fuel supply system a switching valve, arranged between the fuel injection pump and the tank, is actuated by a bimetallic element. Parallel to the switching valve is provided a throttle for continuous air venting. A pressure control valve with a low opening pressure is installed in the connection between the switching valve and the filter. The heated overflow fuel quantities are mixed with cool fuel from the tank and therefore the danger of clogging of the filter, which could be caused by paraffin separation, is substantially reduced.

摘要： In the pump work chamber of a fuel injection pump, the main fuel delivered by a first metering valve is admixed with at least one further additional fluid by means of a second metering valve via a second inflow conduit. The two metering valves inserted into the inflow conduits and being electromechanically actuatable receive control pulses (I.sub.Z1, I.sub.Z2) dependent on operating characteristics (n, T, S, L) from an electric control unit. By means of the metering into the pump work chamber, the respective amounts of the fuel components are very well mixed or emulsified and pumped to the injection nozzle. The electric triggering of the metering valves enables a rapid adaptation from one stroke to another of the mixture ratio of the various fuel components to the instant operating condition of the internal combustion engine. A particularly advantageous feature is the use of a refill reservoir receiving the return-flow fuel quantity diverted at the end of supply and returning it to the pump work chamber before the next subsequent supply stroke begins, this refill chamber being connected to an overflow conduit controlled by an oblique control edge on the pump piston.

摘要： The fuel injection quantity of a fuel injection apparatus provided with a fuel injection pump is electrically regulated by means of the opening duration of a metering valve. Additionally, a shift in the instant of supply onset controlled in accordance with operating characteristics is attained by means of a change in the return-flow fuel quantity, which is diverted into a refill reservoir and then refilled completely into the pump work chamber by the beginning of the next subsequent injection stroke. Serving as the sole connection between the refill reservoir and a pump work chamber is an overflow conduit, which is opened by two control locations on the pump piston at the end of a supply and shortly prior to the bottom dead center. Both the pump cylinder with the pressure valve and the refill reservoir and the metering valve are inserted in a leak-fuel-proof manner in a cylinder head of the pump housing, which is embodied in two parts. The decreased idle volume, the reduction of possible leakage points, and the complete refilling of the return-flow fuel quantity assure that the fuel injection quantity is determined unequivocally by the opening duration of the metering valves.

摘要： A fuel supply apparatus for internal combustion engines is proposed, which has a fuel injection pump for supplying a regulatable fuel injection quantity, a ventilation apparatus for the fuel injection pump, a fuel quantity meter and a means of exhaust gas recirculation controlled by fuel quantity. A ventilation valve responding to a predetermined pump interior pressure is included in an overflow line in order to cool the fuel injection pump by connection with the fuel supply container. The fuel quantity meter is embodied as a spring-loaded piston-type fuel quantity meter and has a travel receptor which generates an electrical output signal and delivers it to a control member of the exhaust gas recirculation system for varying the recirculated exhaust gas quantity accordingly.

摘要： A fuel injection apparatus (FIG. 1) for internal combustion engines is proposed, in which the onset and end of injection are determined by means of a hydraulically actuated control slide. The injection pumps of the apparatus, preferably combined with an injection nozzle to make a pump/nozzle unit, have a central control fuel source represented by a supply pump and a first pressure limitation valve, which generates a control pressure (p.sub.S) actuating the control slide which is several times greater than the supply pressure (p.sub.V) determined by a second pressure limitation valve. In order to initiate the onset of injection, the control slide is placed under control pressure (p.sub.S) by a valve assembly via a distributor apparatus and closes an overflow channel leading out of the pump work chamber. In order to control the end of injection, the control slide during its return stroke again relieves this overflow channel toward a low-pressure line. The control pressure (p.sub.S) in the control pressure line required for actuating the stroke movement of the control slide is established by means of blocking the outflow out of this line by means of the valve assembly.
