摘要： A fuel injection pump is proposed, based on a fuel injection pump of a known type, which has an adjusting member for determining the injection duration and is provided with a throttle device for determining the effective supply stroke of the pump piston. In accordance with the invention it is proposed that the position of the throttle device be varied by means of a pressure control device, which is controllable by signals of an rpm-dependent electronic control unit. The position of the adjusting member determining the duration of injection remains as constant as possible, while the throttle device adjusts the flowthrough cross section of a connecting line leading from the pump work chamber to a fuel withdrawal chamber in accordance with rpm. Thus it is possible, in particular given the small injection quantities required during idling, to effect a uniformly small injection quantity per unit of time during a relatively long injection duration; this results in a substantial reduction in noise.

摘要： An apparatus for ascertaining open- and closed-loop control variables of an internal combustion engine, in particular a Diesel engine, on the basis of individual operating characteristics. The individual open- and closed-loop control variables are each ascertained in an individually computer-controlled manner immediately prior to their being needed. This manner of determining the individual values is particularly amenable to realization in large Diesel engines which operate relatively slowly, but it is applicable in principle to all types of internal combustion engines. The proposed apparatus includes an rpm regulator having a subsequent minimum-value selection circuit and calculation circuits for the onset and the duration of injection. Cylinder selection circuits for controlling the rotary direction are also provided. They determine both the particular metering valve being used and the corresponding starting-air valves for controlling the starting process.For the sake of providing precise fuel metering, the opening duration of the metering valves is made dependent on the fuel pressure prevailing at a particular time. What is of the essence in the apparatus is that the fuel requirement at a particular time is determined immediately prior to the metering thereof, and thus the time required for reacting to changed circumstances is reduced to a minimum.

摘要： A device is proposed for generating control signals with a primary and an auxiliary control unit, having an error indication circuit layout and a subsequently disposed switchover device from the primary to the auxiliary control unit. The auxiliary control unit operates in parallel with the primary control unit and emits monitoring signals spaced apart in time from those of the primary control unit, which do not yet influence the consumer. If the device is put to use as an injection signal generator in internal combustion engines, then it is recommended that the auxiliary control unit emit its output signal either one cycle later, or 180.degree. of crankshaft angle later, than does the primary control unit. The occurrence of the individual signals can be detected and evaluated. Upon the appearance of an error, the former auxiliary control circuit can then be switched over to become the primry control circuit; in that event, then a reversal must then be effected in the times when the individual pulses occur.

摘要： An apparatus for removing solid particles from internal combustion engine exhaust gases is proposed, in which the flow of exhaust gas travels at a high speed of more than 2.5 m/sec through an elongated tube (4), in which a corona discharge takes place from a coaxial spray disk/electrode arrangement toward the wall of the tube. Inside the tube, the soot particles are agglomerated to form larger particles, which are not deposited on the walls because of the high flow speed, which then carries them to a centrifugal precipitator, leading away from which are a tube carrying scrubbed exhaust gas and an outlet having a small quantity of exhaust gas highly enriched with soot. This soot-enriched flow of exhaust gas can advantageously be recirculated to the intake side of the associated engine for afterburning.

摘要： A fuel delivery apparatus is proposed for mixture-compressing, externally ignited internal combustion engines, which serves to meter a fuel quantity adapted to the quantity of air induced and to regulate the fuel-air mixture in accordance with operational characteristics of the internal combustion engine. The fuel delivery apparatus comprises a fuel metering system actuated by an air measuring element arranged in the air induction line of the internal combustion engine, while the air measuring element has a control body which controls the size of the air induction tube cross-sectional area, a radial vane which is pivotably fixed in a work chamber, and a damping vane fixed in a damping chamber. The radial vane separates the work chamber into partial chambers and is impacted upon by the pressure upstream and downstream of the control body in such a manner that a force engages the radial vane which is capable of moving the control body in the direction of an enlargement of the controlled induction tube cross-sectional area and which acts counter to a return force. The damping vane separates the damping chamber into a pressure chamber and a throttle chamber; the pressure chamber is connected with atmospheric pressure or with the pressure upstream of the control body, and the throttle chamber, into which the damping vane moves during an opening movement of the control body, is connected with the pressure chamber via a throttle point. The throttle chamber and/or the pressure chamber of the damping chamber are capable of being connected with the induction tube section downstream of the control body by means of contro valves in accordance with operational characteristics of the internal combustion engine, for the purpose of influencing the fuel-air mixture furnished to the internal combustion engine.

摘要： A method is proposed for improving the operating behavior of motor vehicles driven by an internal combustion engine and especially to reduce jerking or bucking. The jerking, caused by rapid changes in engine torque, is damped by adapting the torque of the engine to the increase in output of the drive train of the vehicle. To this end, the deflection of the engine relative to the motor body is detected and used for vaying the fuel quantity metered to the engine. A differentiating member interposed between the engine and the body acts upon the fuel quantity adjusting device of the fuel metering device.

摘要： A fuel injection system for externally ignited engines employing continuous manifold injection includes a fuel metering valve assembly. The control slide of this valve assembly is actuated by the air-flow through the induction manifold and controls the size of fuel flow apertures. A differential pressure valve normally maintains a constant pressure difference across these metering valve apertures. The magnitude of this normally constant pressure difference can be altered in response to signals obtained from or measurements performed on operational parameters of the engine; for example, the oxygen content of the engine's exhaust gases.

摘要： A device is proposed for generating specific electrical voltage values for consumers associated with an internal combustion engine. The device also encompasses a voltage elevating circuit which can be switched on in the vicinity of the minimum voltages for the consumers. This means that this voltage elevating circuit does not need to be switched on continuously during engine operation, but rather only at times of increased power needs. The voltage elevating circuit has a series circuit of a coil 20 and a diode 21 in a voltage supply line, and the connecting point of these two components is briefly closed off from the other supply line in a clocked manner. The activation of the voltage elevating circuit can be switched on and off in accordance with the input and output voltages and in accordance with the maximum permissible switching current. Depending on the clock frequency of the switch 23, the line inductance of the supply line suffices as an inductance 20.

摘要： A device is proposed for drift compensation in fuel metering systems, in which it is not the metered quantity as such which is controlled in closed-loop fashion, but rather only the position of a quantity-determining member. The object of the invention is to maintain or re-obtain the original association between the fuel quantity and the position signal of the quantity-determining member for the purpose of providing a correct indication of the load state existing at a particular time. The drift compensation is intended to be capable of being performed manually, semi-automatically, or automatically, in an additive and/or multiplicative manner. It can furthermore be realized via a preferably rpm-dependent characteristic curve. The various values may be ascertained, for instance, in connection with running-out and running-up tests.

摘要： In the method according to the invention, the inlet pressure and the inlet cross section of the fuel pre-stored in the pump work chamber is constant, and it is solely the opening duration of an inlet valve which is electrically regulated. In addition, a shift in the instant of supply onset controlled in accordance with operating characteristics is attained by means of a variation in the return-flow fuel quantity. A shift in the instant of supply onset, which is undesired when there is a change in the quantity of fuel to be injected, is prevented by means of a simultaneously-effected correction of the return-flow fuel quantity. A fuel injection apparatus suitable for performing the method has, as the inlet valve, a magnetic valve which determines the quantity of fuel pre-stored in the pump work chamber. The rotary position of the pump piston is variable in order to shift or correct the instant of supply onset by means of an adjacent device actuated by an electromechanical adjustment element. An electric control device emitting the metering pulse and a control pulse is connected with a set-point transducer and an adjustment-path transducer of the adjustment device. The apparatus can be equipped with either a pump/nozzle or a normal piston injection pump supplying the injection nozzle via a pressure line, or with a distributor injection pump.
