摘要： A fuel injection pump in which the quantity adjustment member has a travel limitation in the form of an adjustable stop, which is adjusted in accordance with the displacement of an adjusting piston in accordance with a contour defined on the adjusting piston. The displacement of the adjusting piston is effected with the rpm-dependent pressure of the suction chamber of the fuel injection pump, and the work chamber preceding the adjusting piston can be uncoupled from the suction chamber via a throttle. The maximum displacement of the adjusting piston is limited by a stop which is adjustable in accordance with charge pressure or by a pressure control device by means of which the pressure in the work chamber can be adjusted or limited.

摘要： An apparatus is proposed for positionally fixing a drive shaft disposed in a fuel injection pump for internal combustion engines in a predetermined rotary position, in particular one associated with the onset of fuel supply, and for measuring and testing this rotary position. The apparatus is provided with an apparatus into the reception bore of which either a holder element or an electric pulse transducer can be inserted. An element firmly connected with the drive shaft is provided with an angle-indicator marking, which is equipped both as a coupling element for the position-fixing apparatus and as a pulse trigger for the pulse transducer. The apparatus can thus be used both as a locking apparatus for mounting the injection pump on the engine and, with the pulse transducer inserted, as a measurement and testing apparatus.

摘要： A fuel injection arrangement for internal combustion engines, particularly for diesel engines, is indicated, in which the fuel injection is divided into an advance injection and a main injection for the purpose of noise reduction. An advance injection unit (27) is provided for the purpose of proportioning the advance injection quantity and a fuel injection pump of a conventional construction is provided for proportioning the main injection quantity. For an optimal design of the advance injection quantity with respect to noise reduction without influencing the main injection quantity, the advance injection unit (27) comprises a high-pressure storage (28), which is compressed to injection pressure, and at least one solenoid valve (30), which is controlled with respect to time. The advance and main injections are preferably effected via separate nozzle cross sections (21, 22).

摘要： A fuel injection system for Diesel internal combustion engines, particularly vehicle Diesel engines, is proposed which has a full-load stop dependent on atmospheric pressure. The position of the full-load stop which adapts the injection quantity to the variable ambient air pressure is derived from an air pressure adjusting member and transmitted onto the full-load stop via a transmission member. A locking mechanism, which locks the transmission device in a plurality of positions counter to the force exerted by the full-load stop, is associated with the transmission member. The transmission member has two disks draggably coupled within a predetermined range, one of which disks is actuated by the air pressure adjusting member and the other of which disks cooperates with the full-load stop. The draggable coupling effects an adjustment of the full-load stop, if the full-load stop is relaxed, so that the air pressure adjusting member need exert no more than a small adjusting force.

摘要： A method and an apparatus are proposed for determining and controlling an exhaust gas recirculation rate in internal combustion engines (Diesel engines), wherein an adjusting member in the exhaust gas recirculation line is adjusted by a regulator in order to attain precise regulation of the exhaust gas quantity recirculated to the aspirated air zone. The regulator is supplied with the exhaust gas temperature (T4) measured at a given time as the load signal for the engine. The comparison value of the regulator is then either an actual value of the exhaust gas recirculation rate, ascertained by means of effective temperature measurements in the intake zone of the engine, or a set-point differential temperature which is produced by means of measuring the aspirated air quantity at a given time and the rpm.

摘要： A fuel quantity measuring apparatus, preferably for a Diesel engine, is proposed in which the course of the fuel pressure is evaluated. A specialized pressure gradient of a first polarity marks the onset of supply or injection, and the maximum of the pressure gradient of the other polarity represents the end of injection or supply. The question of which designation prevails, whether injection onset and end or supply onset and end, is determined by the measurement location, that is, whether it is in the direction of the injection valve or in the direction of the supply element of the fuel supply pump. The injection quantity, for example, may be determined via the integral of the pressure during the metering period. It is recommended, when a piezoelectric pressure receptor is used, that a resistor-capacitor element be switched parallel thereto.

摘要： A method is proposed in which the injection pump, having been adjusted in terms of the supply quantity and of the supply onset, is provided on a test bench, before being mounted on the internal combustion engine, with an electric pulse transducer, whose mounted position is marked on the injection pump. The pump may also be corrected, at a fixed test rpm, to a set-point value fixed relative to the supply onset signal by means of measuring the signal distance between the supply onset signal of a signal transducer measuring the dynamic supply onset and the rotary-position signal of the pulse transducer. The injection pump, with the camshaft rotated into the rotary position associated with the dynamic supply onset, is mounted on the engine which has been brought with its crankshaft into the associated working position. For testing and if needed correcting the mounted position of the injection pump on the engine, only the signal distance between the rotary-position signal and a dead-center signal of a dead-center transducer secured on the engine is tested and corrected if needed to a fixed set-point value. This measurement can be performed with a conventionally available ignition angle testing device.

摘要： A fuel injection pump is proposed in which the fuel supply quantity supplied to the injection location is determined by metering the quantity of fuel aspirated. The metering of the aspirated quantities is effected with the aid of at least one magnetic valve which is located in the fuel supply line leading to the fuel injection pump and with the aid of a control edge moved in synchronism with the rotation of the fuel injection pump, which controls the communication between the fuel supply line and the pump work chamber in series with the magnetic valve. The opening times of the two control locations are each longer than the maximum metering time, the overlapping time of the two control times determining the opening time of the communication between the fuel supply and the pump work chamber. The metering time is thus determined on the one hand by the switching time of the control edge moved in synchronism with the rpm and the other by a switching process of the magnetic valve.
