Description
Schnellabschaltung von Dieselmotoren Rapid shutdown of diesel engines
Die Erfindung betrifft eine Anordnung zum abschalten eines Dieselmotors, beispielsweise einer Dieselzuglaufkatze, insbesondere im Untertagebetrieb mittels eines in der Kraftstoffleitung zwischen Kraftstoffpumpe und Einspritzpumpe befindlichen pneumatisch gesteuerten Kraftstoff-Absperrventils.The invention relates to an arrangement for switching off a diesel engine, for example a diesel train trolley, especially in underground operation by means of one located in the fuel line between the fuel pump and the injection pump pneumatically controlled fuel shut-off valve.
Bei unkontrollierbaren Temperaturanstieyen, bei Störungen am Motor, Getriebe oder an der Bremsanlage und vor allem im Brandfall ist es im Untertagebereich unbedingt erforderlich, den Motor, beispielsweise einer Dieselzuglaufkatze, schnellstmöglich abzustellen.In the event of uncontrollable temperature rises, in the event of faults in the motor, Transmission or on the brake system and especially in the event of a fire, it is in the underground area It is absolutely necessary to switch off the engine, for example a diesel trolley, as quickly as possible to turn off.
Bei der bekannten Anordnung zum Abschalten eines Dieselmotors, wie sie nach der eingangs erwähnten Gattung beschrieben ist, sperrt ein über Temperaturfühler ausgelöstes Druckluftabsperrventil die Druckluftleitung, so daß das in die Kraftstoffleitung eingebaute pneumatisch gesteuerte Kraftstoff-Absperrventil die Kraftstoffzufuhr vom Kraftstofftank über die Kraftstoffpumpe den Kraftstoffilter in die Einspritzpumpe des Motors unterbricht. Da jedoch der in der Leitung im Bereich der Einspritzpumpe befindliche Kraftstoff im Motor weiter verbrannt wird, bis die Kraftstoffzufuhr wirksam wird, wird bis zum effektiven Stillstand des Dieselmotors bei der oben beschriebenen entsprechenden Unterbrechung ein Zeitraum von 60 Sekungen benötigt.In the known arrangement for switching off a diesel engine, such as it is described according to the type mentioned at the beginning, locks a temperature sensor triggered compressed air shut-off valve the compressed air line, so that the pneumatically controlled fuel shut-off valve built into the fuel line the fuel supply from the fuel tank via the fuel pump the fuel filter interrupts in the injection pump of the engine. However, since the one on the line in the area The fuel in the engine of the injection pump continues to be burned until the Fuel supply becomes effective until the diesel engine comes to a standstill a period of 60 seconds with the corresponding interruption described above needed.
Da das Weiterlaufen des Motors insbesondere im Untertagebereich zu größten sicherheitstechnischen Schwierigkeiten führen kann, hat sich die Erfindung die Aufgabe gestellt eine Anordnung zum Schnellabschalten von Dieselmotoren zu schaffen, die in sehr kostengünstiger Weise herstellbar ist, die nachträglich einbaubar ist und in einfacher Weise ein sofortiges Abschalten bei einer erforderlich werdenden Unterbrechung des Laufs eines Motors gewährleistet.Since the engine continues to run, especially in underground areas Can lead to major safety difficulties, the invention the task set to create an arrangement for the rapid shutdown of diesel engines, which can be produced in a very cost-effective manner, which can be retrofitted and, in a simple manner, immediate shutdown when it becomes necessary Interruption of the running of a motor guaranteed.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Regelstange der Einspritzpumpe mit einem Gaszylinder bekannter Bauweise verbunden und der Gaszylinder an die das Absperrventil beaufschlagende Druckluftleitung über eine zusätzliche Leitung angeschossen ist.This object is achieved according to the invention in that the control rod the injection pump is connected to a gas cylinder of known construction and the gas cylinder to the compressed air line acting on the shut-off valve via an additional Line is shot.
Im Rahmen der Erfindung erweist es sich als besonders vorteilhaft, daß die Abzweigung der zusätzlichen Leitung von der Druckluftleitung zwischen dem Kraftstoff-Absperrventil und einem von Hand zu betätigenden, zur Überprüfung erforderlichen, Druckluftabsperrventil vorgesehen ist.In the context of the invention, it proves to be particularly advantageous that the branch of the additional line from the compressed air line between the Fuel shut-off valve and a manually operated, required for checking, Compressed air shut-off valve is provided.
Der technische Fortschritt der Erfindung ist im wesentlichen darin begründet, daß die für die untertägigen Sicherheitsbestimmungen erforderliche Schnellabschaltung mit einem geringstmöglichen technischen Aufwand und einer großen Effektivität erwirkt werden kann.The technical progress of the invention is essentially therein justifies that the emergency shutdown required for the underground safety regulations achieved with the least possible technical effort and great effectiveness can be.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung, die in schematisierter Form die Anordnung zur Abschaltung von Dieselmotoren wiedergibt, dargestellt und wird im folgenden näher erläutert.An embodiment of the invention is shown in the drawing in shows the arrangement for switching off diesel engines in a schematic form, and is explained in more detail below.
Der in der zeichnerischen Anordnung in schematisierter Form dargestellte Dieselmotor 1 wird über eine Einspritzpumpe 2 mit Kraftstoff beaufschlagt. Der Kraftstoff wird aus einem Tank 4 mittels einer Kraftstoffpumpe 5 über eine entsprechende Kraftstoffleitung 3 der Einspritzpumpe 2 zugeführt. In der Leitung 3 ist vor dem Eintritt des Kraftstoffs in die Einspritzpumpe 2 ein Kraftstoffilter 7 angeordnet.The one shown in the drawing arrangement in schematic form Diesel engine 1 is supplied with fuel via an injection pump 2. The fuel is from a tank 4 by means of a fuel pump 5 via a corresponding fuel line 3 of the injection pump 2 is supplied. In line 3 is before the entry of the fuel A fuel filter 7 is arranged in the injection pump 2.
Die bisher bekannte Einrichtung zum Abschalten eines Dieselmotors 1 besteht im wesentlichen aus einem pneumatisch gesteuerten Kraftstoff-Absperrventil 6, welches in die Kraftstoffzufuhrleitung 3 zur Einspritzpumpe 2 des Motors 1 angeordnet ist. Das Absperrventil 6 wird über eine Druckluftleitung 8 mit Druckluft aus einem Druckluftbehälter 11 gespeist. In die Leitung 8 ist ein weiteres Druckluftabsperrventil 10 eingebaut, welches automatisch beispielsweise durch Temperaturfühler im Brandfalle die Druckluftleitung 8 sperrt. Dementsprechend wird das pneumatisch gesteuerte Absperrventil 6 gesperrt und die Kraftstoffzufuhr in der Leitung 3 unterbrochen.The previously known device for switching off a diesel engine 1 essentially consists of a pneumatically controlled fuel shut-off valve 6, which is arranged in the fuel supply line 3 to the injection pump 2 of the engine 1 is. The shut-off valve 6 is via a compressed air line 8 with compressed air from a Compressed air tank 11 fed. In the line 8 is another compressed air shut-off valve 10 built-in, which automatically, for example, by temperature sensor in the event of fire the compressed air line 8 blocks. Accordingly, the pneumatically controlled shut-off valve 6 blocked and the fuel supply in line 3 interrupted.
Zur Überprüfung des pneumatischen Absperrventils 6 ist in der Leitung 8 ein von Hand zu betätigendes Druckluftabsperrventil 9 vorgesehen.To check the pneumatic shut-off valve 6 is in the line 8 a manually operated compressed air shut-off valve 9 is provided.
Um nun unter Beibehaltung dieser Anordnung eine Schnellabschaltung zu erzielen ist die Regelstange 12 mit einem Gaszylinder 14 bekannter Bat art und der Gaszylinder 14 wiederum über eine zusätzliche Leitung 15 mit der Leitung 8 verbunden. Der Gaszylinder 14 hält unter dem bestehenden Gasdruck die Regelstange 12 in der vorgegebenen Position. Bei plötzlicher Druckunterbrechung in der Leitung 15 fährt der Kolben des Zylinders ein und zieht die Regelstange 12 aus ihrer bisherigen Position auf die gewünschte Nullförderung. Damit ist die Kraftstoffzufuhr zum Dieselmotor 1 augenblicklich unterbrochen.To now, while maintaining this arrangement, a quick shutdown to achieve the control rod 12 with a gas cylinder 14 known Bat art and the gas cylinder 14 is in turn connected to the line 8 via an additional line 15. The gas cylinder 14 holds under the existing one Gas pressure the control rod 12 in the specified position. In the event of a sudden pressure interruption in the line 15 the piston of the cylinder retracts and pulls the control rod 12 out of its previous position Position on the desired zero funding. This is the fuel supply to the diesel engine 1 interrupted immediately.
