Abstract

The method involves the on-board computer closing the exhaust gas flap and opening the exhaust gas feedback valve (11) to its maximum extent by sending suitable signals with the clutch (20) decoupled, before the diesel engine (10) reaches its upper critical revolution rate. If a primary retarder is present in the engine, it is used to automatically exert a defined braking force on the engine crankshaft.

Description

Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Anspruches 1.The invention relates to a method according to the preamble of claim 1.

Ein Ausführungsbeispiel ist der elektrohydraulische Notabsteller, der, wenn der Dieselmotor kritische Drehzahlen erreicht, die Treibstoffzufuhr zum Dieselmotor unterbricht. Dieser elektrohydraulische Notabsteller ist teuer und störanfällig. Eine Störanfälligkeit des Abstellers kann man in diesem Fall aber überhaupt nicht zulassen, da ein Versagen dieses Bauteils in dem Moment, in dem es funktionsfähig wirken soll, zur Selbstzerstörung des Dieselmotors durch nicht mehr zulässige Drehzahlen führt.One embodiment is the electro-hydraulic emergency stop, which, when the diesel engine critical speeds reached, the fuel supply to the diesel engine is interrupted. This electro-hydraulic emergency stop is expensive and prone to failure. A In this case, it is not possible to allow the storage rack to malfunction, there failure of this component the moment it works should, for self-destruction of the diesel engine by no longer permissible speeds leads.

Ein Festsetzen bzw. Blockieren der Regelstange ist äußerst selten und ist meistens auf verunreinigten oder qualitativ schlechten Treibstoff, der über längere Zeit getankt wurde, zurückzuführen. Wenn während des Betriebs, z. B. im oberen Teillastbereich, ein Blockieren der Regelstange eintritt und keine Notabstellung des Dieselmotors vorhanden ist und die Kupplung geöffnet wird, so wird sich der Dieselmotor etwa innerhalb einer Sekunde durch Überdrehzahl selbst zerstören.Locking or blocking the control rod is extremely rare and is usually for contaminated or poor quality fuel that has been used for a long time was attributed. If during operation, e.g. B. in the upper part-load range, Blockage of the control rod occurs and no emergency shutdown of the diesel engine is present and the clutch is opened, so the diesel engine destroy yourself within one second by overspeeding.

Ein Abschalten des Betriebsstromes mit dem

Figure 00010001
Zündschlüssel" hilft da nichts, da der Dieselmotor ein Selbstzünder ist und die Regelstange auch durch Wegnahme des Betriebsstromes - im Fall der blockierenden Regelstange - nicht zurückgehen wird.Switching off the operating current with the
Figure 00010001
Ignition key "does not help because the diesel engine is a self-igniter and the control rod will not go back even if the operating current is removed - in the case of the blocking control rod.

Bei magnetventilgesteuerten Einspritzanlagen wie Common Rail ist noch zu wenig Erfahrung vorhanden, aber es ist vorstellbar, daß durch Ansammlung von Partikeln in der Einspritzdüse die Düsennadeln nicht mehr richtig schließen könnten.In the case of solenoid valve-controlled injection systems such as common rail, this is still not enough Experience exists, but it is conceivable that through the accumulation of particles could no longer properly close the nozzle needles in the injection nozzle.

Aufgabe der Erfindung ist es, eine äußerst zuverlässige Notabstellung für einen Dieselmotor darzustellen. Die Aufgabe wird erfindungsgemäß durch die Merkmale des Verfahrens nach Anspruch 1 gelöst. The object of the invention is an extremely reliable emergency stop for a diesel engine to represent. The object is achieved by the features of Method according to claim 1 solved.

Durch das Verfahren wird, wenn der Bordcomputer ein Hochlaufen des Dieselmotors erkennt, die drehzahlregelnden Mechanismen des Dieselmotors nicht mehr wirken, wenn die Kupplung geöffnet wird und bevor eine kritische Drehzahl erreicht wird, durch ein Signal aus dem Bordcomputer die Abgasklappe geschlossen und das Abgasrückführungsventil auf ein Maximum geöffnet.By the method, when the on-board computer starts up the diesel engine recognizes that the speed-regulating mechanisms of the diesel engine no longer work, when the clutch is opened and before a critical speed is reached, the exhaust flap and the exhaust gas recirculation valve are closed by a signal from the on-board computer opened to a maximum.

Es wird ein Kurzschlußkreislauf der Verbrennungsluft gebildet, indem Abgas in den Ansaugluft-Verteilerkasten eingeschoben wird. Der in dem Kurzschlußkreislauf enthaltenen Sauerstoff wird durch weitere Zündungen in den Zylindern schnell verbraucht. Dadurch kann kein zündfähiges Gemisch mehr entstehen, auch wenn weiterhin Dieseltreibstoff eingespritzt wird.A short circuit of the combustion air is formed by exhaust gas into the Intake air distribution box is inserted. The contained in the short circuit Oxygen is quickly consumed by further ignitions in the cylinders. As a result, an ignitable mixture can no longer form, even if it continues to do so Diesel fuel is injected.

Der Drehzahlabfall des Dieselmotors ist bei geöffneter Kupplung sehr schnell, da eine geschlossene Abgasklappe eine Motorbremse darstellt, also sehr wirkungsvoll ist und die rotierende Masse des Dieselmotors diesbezüglich nicht erheblich ist.The drop in speed of the diesel engine is very fast when the clutch is open a closed exhaust flap represents an engine brake, so it is very effective is and the rotating mass of the diesel engine is not significant in this regard.

Wenn ein motorinterner Retarder vorhanden ist, kann auch dieser mit zur Abbremsung herangezogen werden.If there is an internal retarder, this can also be used to slow down be used.

Die Einspritzung des Dieseltreibstoffes in den Verbrennungsräumen erfolgt über Mehrlochdüsen, so daß der Treibstoff wie ein Nebel verteilt wird. Beim Verdichtungstakt wird dann der Treibstoff und das - in diesem Fall keinen Sauerstoff mehr enthaltende - Gas verdichtet, durch die Verdichtung erhitzt und als nicht zündfähiges Gasgemisch beim nächsten Takt ausgeschoben. Es wird also im Verbrennungsraum keine nennenswerte Ansammlung von Treibstoff geben, so daß ein Hydraulikschlag ausgeschlossen werden darf. Allerdings kann sich, wahrscheinlich in der Nähe der Abgasklappeneinrichtung oder im Katalysator oder in beiden Vorrichtungen, je nach Anordnung, Treibstoff in flüssiger Form ansammeln. Es darf deshalb der Dieselmotor, wenn eine Notabstellung durchgeführt wurde, nicht ohne weiteres wieder anschaltbar sein. The diesel fuel is injected into the combustion chambers via Multi-hole nozzles so that the fuel is distributed like a mist. At the compression stroke then becomes the fuel and - in this case no longer containing oxygen - Compressed gas, heated by the compression and as a non-ignitable gas mixture pushed out at the next bar. So it gets in the combustion chamber give no appreciable accumulation of fuel, so that a hydraulic shock may be excluded. However, it can, probably near the Exhaust valve device or in the catalytic converter or in both devices, depending on Arrangement, accumulate fuel in liquid form. The diesel engine, if an emergency shutdown has been carried out, it cannot easily be switched on again be.

Vielmehr muß entweder durch entsprechende Temperatursensoren, die eine Wiederinbetriebnahme freigeben oder durch Eingabe eines elektronischen Schlüssels, den nur eine Vertragswerkstätte hat, der Bordcomputer eine Information erhalten, daß der Dieselmotor wieder inbetriebnehmbar ist.Rather, it is necessary either through appropriate temperature sensors to restart the system release or by entering an electronic key, which only an authorized workshop has, the on-board computer receives information, that the diesel engine can be put into operation again.

Im Normalfall wird ein Temperatursensor im Abgastrakt, der üblicherweise bereits vorhanden ist, genügen, damit der Bordcomputer unterhalb einer Temperatur, von z. B. 60°C, ein Signal an den Rechner für die elektronisch geregelte Treibstoffzumessung gibt, daß der Dieselmotor wieder inbetriebnehmbar ist. Der Dieseltreibstoff, der möglicherweise im Abgastrakt vorhanden ist, wird dann relativ langsam verbrennen und nicht wie Benzin explodieren.Normally there is a temperature sensor in the exhaust tract, which is usually already is present, sufficient for the on-board computer to be below a temperature of e.g. B. 60 ° C, a signal to the computer for electronically controlled fuel metering indicates that the diesel engine can be put into operation again. The diesel fuel, which may be present in the exhaust tract will then burn relatively slowly and not explode like gasoline.

In der Fig. 1 ist der Dieselmotor 10 mit der Abgasrückführungseinrichtung 14 und der Abgasklappeneinrichtung 13 gezeigt. Für eine Notabstellung des Dieselmotors 10, die erforderlich ist, wenn die Regelstange 17 (Fig. 2) der Einspritzpumpe 16 (Fig. 2) blockiert ist, und die Kupplung 20 (Fig. 2) geöffnet wird, wird durch ein Signal aus dem Bordcomputer die Abgasklappe 12 geschlossen und das Abgasrückführungsventil 11 auf das Maximum geöffnet. Dadurch entsteht eine Art Kurzschlußkreislauf zwischen Abgassammler 16 und Ansaugluft-Verteilerkasten 15. Der in diesem Kurzschlußkreislauf enthaltene Sauerstoff wird durch Zündungen in den Zylindern schnell verbraucht. Es kann auch keine frische Ansaugluft 19 mehr angesaugt werden, da sich das Abgas 19' vor der Abgasklappe 12 staut. In Fig. 1, the diesel engine 10 with the exhaust gas recirculation device 14 and the exhaust valve device 13 shown. For an emergency shutdown of the diesel engine 10, which is required when the control rod 17 (FIG. 2) of the injection pump 16th (Fig. 2) is blocked, and the clutch 20 (Fig. 2) is opened by a Signal from the on-board computer, the exhaust flap 12 closed and the exhaust gas recirculation valve 11 opened to the maximum. This creates a kind of short circuit between exhaust manifold 16 and intake air distribution box 15. The in this Short circuit is contained oxygen by ignitions in the cylinders quickly consumed. Fresh intake air 19 can also no longer be drawn in be because the exhaust 19 'jams in front of the exhaust flap 12.
