摘要： An apparatus is proposed which serves the purpose of load-dependent actuation of an adjustment device, wherein the cross section and/or the pressure drop of an exhaust recirculation line in an internal combustion engine can be varied in accordance with load. An injection pump of conventional design is associated with the internal combustion engine and further includes a quantity adjustment device, the position of which acts as a control variable for the load. With this control variable, a booster apparatus is controlled via a comparison apparatus; the output variable of the booster apparatus in turn is the control variable for the actuation of an adjustment device which acts on an exhaust recirculation control apparatus. When a threshold value for load is exceeded, the exhaust recirculation is precluded. The control variable is preferably formed as a fuel pressure signal with the fuel withdrawn from the suction chamber of the injection pump. Apparatuses are proposed by means of which, in the event of the actuation of the control apparatus for exhaust recirculation, the smallest possible removal quantity of fuel is required for control purposes.

摘要： Associated with the fuel controller of a supercharged diesel engine is a mechanism which limits the maximum fuel quantity in all operational states as defined by engine speed and air flow rate. This mechanism includes a three dimensional cam, displaced in rotation by a first transducer responsive to rpm or air flow rate and further displaced axially by a second transducer responsive to the other of these variables. A cam follower attached to the main fuel control rod of the controller makes contact with and follows the surface of the cam, thereby limiting the maximum fuel quantity admitted to the engine. Special provisions permit an enlarged starting fuel quantity and also permit corrections on the basis of further parameters, such as temperature. Several embodiments are presented.

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 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 fuel injection system for an internal combustion engine includes an air flow responsive throttle element in the induction tube which is subject to an adjustable elastic restoring force. The throttle element is attached to a bushing which rotates about a pivotal shaft mounted within the induction tube. A control slot in the bushing is covered to varying extent by a control edge on the pivotal shaft so that fuel which enters a groove in the shaft is metered out according to the relative rotation of shaft and bushing. The relative position of the throttle can be adjusted by a pressure cell.

摘要： The invention is directed to an arrangement for rapidly adjusting an electromagnetic load associated with internal combustion engines. The output signals of two control systems are combined in a logic circuit such that priority is assigned to one of the two control systems. Dependent on the output signal of the higher-order control system, an evaluation circuit acts on a switch arrangement to thereby suitably influence the signal resulting from the combining operation of the output signals of the two control systems. This arrangement makes it possible to speed up the delivery of the output signal of the higher-order control system to the electromagnetic load which may be an injection valve, for example. The higher-order control system may be a smooth-running control system.

摘要： An electronic control system for the fuel quantity of an internal combustion engine having self-ignition is proposed, in which above a predetermined load threshold the increase in fuel quantity is limited and a regulation of exhaust gas temperature is performed. The load threshold is preferably approximately 75% of the full-load value, and it may be dependent on operating characteristics, for instance on the rpm. Depending upon the engine type, it may be useful to regulate not the absolute exhaust gas temperature but rather the difference between the exhaust gas temperature and the temperature of the aspirated air.
