Abstract: 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.

Abstract: An apparatus is proposed which serves to regulate the idling rpm of an internal combustion engine. The apparatus includes a bypass line bypassing an arbitrarily actuatable throttle valve in the intake tube. An electromagnetically actuatable bypass valve is disposed in the bypass line for the purpose of controlling supplementary air and is triggerable in accordance with operating characteristics of the engine. In addition, a pressure-sensing adjusting element is also provided, which responds to an abrupt reduction in the intake tube pressure downstream of the throttle device. In accordance with the magnitude of the pressure reduction, this pressure-sensing adjusting element effects a time-limited increase in the supplementary air quantity to the intake tube section downstream of the throttle valve.

Abstract: 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.

Abstract: A fuel injection system is proposed for Diesel type internal combustion engines, by means of which the ignition conditions of a Diesel engine are kept optimal even during operation at high altitudes despite a reduced air charge. The system includes a fuel injection pump equipped with an injection timing adjustment apparatus which functions in accordance with rpm and a control apparatus functions in accordance with the air quantity supplied to the engine. By means of the control apparatus, a correction controlled in accordance with air pressure and therefore dependent on air quantity is superimposed on the change in the onset of the fuel supply controlled by the injection adjuster at least in accordance with rpm. When a hydraulic injection adjuster is used, the supply pressure of a control pump is increased by a correcting final control element of the control apparatus when the air quantity is decreasing in the direction toward an early adjustment of the onset of supply.

Abstract: A fuel injection system is proposed which can be triggered such that when control signals characterizing engine overrunning are present, fuel injection is interrupted. To this end a pressure relief valve is provided, which opens in the presence of control signals characterizing engine overrunning and lowers the fuel pressure upstream of the fuel metering locations and accordingly upstream of the injection valves as well to below the opening pressure of the injection valves, so that no further fuel is injected via the injection valves during engine overrunning.

Abstract: A fuel injection system is proposed which serves to provide the most precise possible adaptation of the fuel-air mixture to operating conditions of the internal combustion engine. The fuel injection system includes metering valves, each of which is assigned one regulating valve, whose movable valve element can be exposed on the one hand to the fuel pressure downstream of the respective metering valve and on the other hand to the pressure in a control pressure line, which is limited on the one hand by an electro-fluid converter of the nozzle/bounce plate type and on the other hand by a control throttle. The electro-fluid converter is triggerable in accordance with operating characteristics of the engine.

Abstract: A differential pressure valve is proposed for a fuel injection system of an internal combustion engine. The differential pressure valve includes a diaphragm embodied as the movable valve element, which separates two chambers from one another. A fuel supply line discharges into one chamber and a valve seat carrier provided with a valve opening protrudes into this chamber. This chamber also houses a filter element and a valve spring is disposed coaxially with the valve seat carrier between upper and lower spring plates. The filter element is disposed such that a subsequent change in the tension of the valve spring is also possible. To this end, the filter element can engage the upper spring plate on one side in a sealing manner and on the other side can be supported in a sealing manner in a groove of the wall of the chamber (FIG. 1). In order to assure the free mobility of the filter element, it is provided with an elastically deformable area. As shown in FIG.

Abstract: A method is proposed for regulating the combustion of operating mixtures in the combustion chambers of internal combustion engines.

Abstract: A method and apparatus for closed-loop control of the air number .lambda. in self-igniting internal combustion engines, wherein with the aid of an ion current sensor disposed in the immediate vicinity of an outlet valve, the extent of the post combustion reaction of the exiting exhaust gases is detected and the ion current produced is compared with a set-point value, which lies within the ion current characteristic curve, which sharply drops within the air number range of .lambda.=1.0-1.5. In accordance with the result of the comparison, one component of the operating mixture of the engine is varied in amount in corrective fashion, so that the set-point value of the ion current is maintained and thus the permissible soot number of the exhaust gas is not exceeded.

Abstract: An apparatus is described for the removal of solid components from the exhaust gas of internal combustion engines, in particular for the removal of soot components from the exhaust gases of self-igniting combustion engines. Under the influence of electrostatic fields, the solid components are diverted and carried to a fresh-air current flowing toward the intake side of the engine. This recirculation of the solid components may be effected either by means of the recirculation of a partial flow of the exhaust gas which has been enriched with solid components, in which case the solid components are deflected into this partial flow in an electrostatic field, or these solid components may be guided into the fresh-air current aspirated by the engine, in this case with the cooperation of a mechanical transport means and electrostatic bonding forces.

Abstract: A rotary magnet control element for a distributor injection pump is proposed, which is universally movable by an adjustment means while an engine in running for adjustment of the position of the rotary magnet relative to an annular slide which is reciprocably disposed on a pump piston.

Abstract: 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.

Abstract: A method for varying the phase spacing of sequential ignition control pulses emitted by an ignition pulse transducer and an apparatus for performing the method are proposed, wherein it is ascertained in the case of the sequential ignition pulses whether their phase spacing has become shorter. If a shortening of the phase spacing is ascertained, then the ascertained phase difference, or a maximal value of the phase difference, is added to the phase spacing of the ignition pulse at that particular time. In this manner, jerking which occurs particularly at constant rpm, when internal combustion engines with externally-supplied ignition used to operate a motor vehicle are driven in the vicinity of the idling rpm, is avoided by simple means.

Abstract: An rpm governor for fuel-injected internal combustion engines is proposed, in particular a centrifugal rpm governor of an injection pump for Diesel motor vehicles, in which the idling rpm is also held constant when the engine is cold or loaded by additional consumers, in order to assure smooth running of the engine and the most favorable values for fuel consumption and exhaust emissions. The governor contains an idling correction apparatus with an electromagnet, which transmits an additional adjustment force, which is preferably independent of travel distance and variable only by the energizing current of a control circuit, onto the governor member via a transmission element. By means of varying or switching on or off of the adjustment force, the idling rpm which is fixed by the initial stress of an idling spring for the warm and unloaded engine is also held constant under changing operational conditions.
