Die Verbreitung der im Englischen „stop and start" genannten Technik ermöglicht es den Motor abzuschalten, während das Auto steht. Dieses Abschalten des Motors erlaubt es Treibstoff zu sparen, dies umso mehr wenn das Kraftfahrzeug häufig in der Stadt bewegt wird oder im Stau steht. Wenngleich das Abschalten des Motors einfach zu bewerkstelligen ist, so ist das erneute Starten des Motors im Gegenzug weniger einfach. Das erneute Starten sollte hinreichend schnell zu bewerkstelligen sein, da ansonst diese Technik „stop and start" für die Fahrzeuginsassen ermüdend und nervig wird. Ein solches Verfahren ist zum Beispiel in der WO 01/63122 beschrieben.The Dissemination of the English "stop and start " Technology allows it shut off the engine while the car stands. This shutdown of the engine allows fuel to save, all the more so if the motor vehicle frequently in the city is moved or stuck in traffic. Although the shutdown The engine is easy to do, so it is restarting the engine in return less easy. The restart should be sufficient be done quickly, otherwise this technique "stop and start "for the vehicle occupants tiring and gets annoying. Such a method is for example in the WO 01/63122 described.

Um dies zu erreichen richtet sich die vorliegende Erfindung auf ein Verfahren zur Kontrolle einer Brennkraftmaschine mit einem temporären Abschaltsystem für den Motor mit folgenden Schritten:
- – Erfassen des vom Fahrer gegebenen Startsignals;
- – Betätigen der Glühstiftkerzen, wenn die Motortemperatur zu niedrig ist;
- – Betätigen der Glühstiftkerzen, wenn die Motortemperatur zu niedrig ist;
- – Starten des Motors;
- – Abschalten des Motors auf Befehl des besagten Systems zum temporären Abschalten;
- – Erneutes Starten des Motors auf Befehl des Systems zum temporären Abschalten;
- Detecting the start signal given by the driver;
- - actuating the glow plugs when the engine temperature is too low;
- - actuating the glow plugs when the engine temperature is too low;
- - starting the engine;
- - switching off the engine on command of said system for temporary shutdown;
- - restarting the engine on command of the temporary shutdown system;
Ein solches Verfahren ist zum Beispiel in der US-A-4 862 846 beschrieben.One such process is described, for example, in US-A-4,862,846.
Erfindungsgemäß erfolgt:
- – Das Zuführen von Kalorien in die Zylinder durch die Betätigung der Glühstiftkerzen;
- – Das Aktivieren der Glühstiftkerzen wird nur in den Zylindern des Motors aktiviert, die während des Stehens des Motors gemäß der Steuerung des Abschaltsystems in einer Kompressionsphase sind, um die Verkürzung der Wiederstartzeit zu optimieren;
- – Das Aktivieren der Glühstiftkerzen erfolgt nicht kontinuierlich um die notwendige Energie zu sparen;
- – Das Betätigungssignal der Glühstiftkerzen hat die Form eines Pulszuges.
- - The feeding of calories in the cylinder by the operation of the glow plugs;
- Activating the glow plugs is activated only in the cylinders of the engine, which are in a compression phase during engine standstill in accordance with the control of the shutdown system in order to optimize the shortening of the restart time;
- - Activating the glow plugs is not continuous to save the necessary energy;
- - The actuating signal of the glow plugs has the form of a pulse train.
Die vorliegende Erfindung wurde auf dem Gebiet der „Stop-and-Start"-Technik gemacht. Diese Technik erlaubt es kontinuierlich das Anhalten und Starten des Verbrennungsmotors zu steuern. Vorzugsweise wird der Motor angehalten, wenn das Fahrzeug steht (oder wenn es sich unterhalb einer Geschwindigkeitsschwelle bewegt) und wird erneut gestartet, wenn der Fahrer startet und ein Gang eingelegt ist. Das erneute Starten kann mit Hilfe eines klassischen Starters erfolgen oder mit einer reversiblen Wechselstromlichtmaschine. Ein üblicher Startvorgang erfolgt ungefähr nach 1,75 Umdrehungen der Kurbelwelle. Für ein erneutes Starten im „Stop-and-Start"-Betrieb sollte der Startvorgang weniger als eine Umdrehung der Kurbelwelle benötigen, um für die Fahrzeuginsassen akzeptabel zu sein.The The present invention has been made in the field of "stop-and-start" technology it continuously stops and starts the internal combustion engine to control. Preferably, the engine is stopped when the vehicle is (or if it is below a speed threshold moved) and is restarted when the driver starts and on Gear is engaged. Restarting can be done with the help of a classic Starters or with a reversible AC alternator. A common one Booting takes place approximately after 1.75 turns of the crankshaft. For a restart in the "stop-and-start" operation of the Starting operation less than a revolution of the crankshaft need to for the Vehicle occupants to be acceptable.
Währenddessen ist es unterhalb einer bestimmten Umdrehungszahl der Kurbelwelle (im Wesentlichen unterhalb 0,7 Umdrehungen) sehr schwierig eine Selbstentflammung des Treibstoffluftgemischs in dem Zylinder beim Starten zu bewirken, da die Kompression in dem Zylinder nicht mehr ausreichend Energie liefern kann.Meanwhile it is below a certain number of revolutions of the crankshaft (essentially below 0.7 turns) very difficult one Self-ignition of the fuel-air mixture in the cylinder during Start causing the compression in the cylinder is no longer can supply enough energy.
Erfindungsgemäß dienen die Glühstiftkerzen, die üblicherweise bei einem Kaltstart verwendet werden, dazu die schwache Kompression in den Zylindern durch eine Kalorienzufuhr zu kompensieren. Dies erfolgt dadurch, indem die Glühstiftkerzen so gesteuert werden, dass sie eine notwendige Restenergie liefern, zusätzlich zu der Energie, die durch die partielle Kompression in den Zylindern geliefert wird, um eine Selbstentflammung zu bewerkstelligen. Dies erlaubt es das erneute Starten zu beschleunigen, da es ermöglicht die erforderliche Umdrehungszahl der Kurbelwelle zu verringern.Serve according to the invention the glow plugs, the usual used in a cold start, in addition to the weak compression in the cylinders by a calorie intake to compensate. This This is done by the glow plugs be controlled so that they provide a necessary residual energy, additionally to the energy caused by the partial compression in the cylinders is delivered to self-ignite. This allows It accelerates the restarting, as it allows the To reduce the required number of revolutions of the crankshaft.
Vorzugsweise erfolgt das Steuern der Glühstiftkerzen zwischen dem Anhalten und dem Wiederstarten des Motors mit Hilfe eines „Stop- and-Start"-Systems, welches mit dem Motor verbunden ist. Diese Steuerung erfolgt über die Motortemperatur, die es ermöglicht die Wärmemenge zu bestimmen, die den Zylindern zugeführt werden muss.Preferably the control of the glow plugs takes place between stopping and restarting the engine with help a "stop-and-start" system, which connected to the engine. This control takes place via the engine temperature, which makes it possible the amount of heat to be determined, which must be supplied to the cylinders.
Vorzugsweise wird die Temperatur in den Zylindern gehalten anstatt die Wärme kurz vor dem erneuten Starten zuzuführen. Um den Bordstrom des Kraftfahrzeugs zu sparen, können die Glühstiftkerzen diskontinuierlich betätigt werden, zum Beispiel mit einem Pulssignal, welches periodisch die Kerzen steuert. Dies ist insbesondere wichtig, wenn der Stillstand des Motors lange dauert. Schließlich kann man vorsehen, eine geringere Temperatur als die optimale Temperatur für eine Selbstentflammung zu halten, und wenn das erneute Starten ausgelöst wird einen stärkeren Strom zu liefern.Preferably, the temperature is maintained in the cylinders rather than supplying the heat just before re-starting. To the on-board power of the To save motor vehicle, the glow plugs can be operated discontinuously, for example with a pulse signal which periodically controls the candles. This is especially important when the engine stops for a long time. Finally, one can foresee keeping a lower temperature than the optimum temperature for self-ignition, and if the re-starting is triggered to provide a stronger current.
Die Leistungsfähigkeit der Glühstiftkerzen hängt natürlich von den Eigenschaften des elektrischen Netzes des Kraftfahrzeugs ab, das in der Motorgruppe installiert ist. Es ist umso leichter mit Hilfe der Glühstiftkerzen zu zünden, je größer die elektrische Leistung des Bordnetzes ist.The capacity of course, the glow plugs depends on the characteristics of the electrical network of the motor vehicle, which is installed in the motor group. It's easier with it Help the glow plugs to ignite, the bigger the electrical power of the electrical system is.
Das „Stop-and-Start"-System weist eine Vorrichtung zur Identifizierung der Motorphase auf, vorzugsweise werden ausschließlich die Kerzen angesteuert, die sich in den Zylindern befinden, die während des Anhaltens des Motors in einer Kompressionsphase sind.The "stop-and-start" system has a Device for identifying the motor phase, preferably become exclusive activated the candles, which are located in the cylinders, the while stopping the engine in a compression phase.
Dies sind im Wesentlichen die Zylinder, in denen ausreichend Energie vorhanden sein wird.This are essentially the cylinders in which sufficient energy will be available.
Die vorliegende Erfindung beschränkt sich nicht auf ein Ausführungsbeispiel sondern umfasst diverse Varianten und Modifizierungen, die der Fachmann ausführen kann. Insbesondere ist es möglich, die Glühstiftkerzen als Funktion des Kompressionsgrades in den Zylindern zu steuern. Ebenfalls kann das Steuersignal der Kerzen ein anderes sein, insbesondere ein kontinuierliches unmittelbar vor dem erneuten Starten des Motors.The present invention limited not on an embodiment but includes various variants and modifications that the skilled person To run can. In particular, it is possible to glow plugs as a function of the degree of compression in the cylinders. Also, the control signal of the candles may be different, in particular a continuous just before restarting the engine.
