Abstract
Description
Die Erfindung betrifft Verfahren zum Betreiben einer Brennkraftmaschine, insbesondere im Stopp-/Start-Betrieb, und eine Vorrichtung hierzu.The Invention relates to methods for operating an internal combustion engine, especially in the stop / start operation, and a device for this purpose.
Beim Abschalten eines Verbrennungsmotors bleibt dieser in einer zufälligen, durch die verbleibende Kompression in den Zylindern mitbestimmten Position stehen. Beim Wiederstart ergeben sich deshalb unterschiedliche Drehwinkel der Kurbelwelle bis der Motor wieder zündet bzw. gezündet werden kann. Insbesondere bei Hybrid-Fahrzeugen mit automatischem Stopp des Motors, wie er z. B. im Segelbetrieb und im Bremsbetrieb auftritt, ergibt sich so eine zufällige, meist länger als notwendige Zeitdauer des Wiederstarts des Antriebs beim erneuten Gas geben, die einen Fahrer wegen der nicht immer gleichen Reaktionszeit des Fahrzeugs verunsichern kann.At the Switching off an internal combustion engine this remains in a random, co-determined by the remaining compression in the cylinders Standing position. When restarting therefore arise different Angle of rotation of the crankshaft until the engine ignites again or ignited can be. Especially with hybrid vehicles with automatic Stop the engine, as he z. B. in sailing and braking operation occurs, this results in a random, usually longer than necessary time of restarting the drive when re-starting Giving gas to a driver because of not always the same reaction time of the vehicle can unsettle.
Aufgabe der Erfindung ist es, den Startvorgang einer Brennkraftmaschine, insbesondere im Stopp-/Start-Betrieb, zu verbessern.task the invention is the starting process of an internal combustion engine, especially in stop / start operation, to improve.
Diese Aufgabe wird erfindungsgemäß durch ein Verfahren mit den Merkmalen des Anspruchs 1 und eine Vorrichtung mit den Merkmalen des Anspruchs 3 gelöst.These The object is achieved by a Method with the features of claim 1 and a device solved with the features of claim 3.
Das erfindungsgemäße Verfahren ist dadurch gekennzeichnet, dass eine Kurbelwelle der Brennkraftmaschine nach deren Abschalten mittels eines Positionsreglers in eine für einen Wiederstart günstige Startlage gebracht wird.The inventive method is characterized in that a crankshaft of the internal combustion engine after switching off by means of a position controller in one for a Restart cheap Starting position is brought.
Die erfindungsgemäße Vorrichtung ist dadurch gekennzeichnet, dass eine Positioniereinrichtung vorgesehen ist, welche die Kurbelwelle nach einem Abschalten der Brennkraftmaschine in eine günstige Startlage positioniert.The inventive device is characterized in that a positioning provided is which the crankshaft after a shutdown of the internal combustion engine in a cheap Starting position positioned.
Durch die Erfindung wird sichergestellt, dass der Verbrennungsmotor nach dem Ausschalten immer so positioniert wird, dass wenigstens ein Zylinder in einer günstigen Position zum Wiederstart steht. Dazu wird der Motor nach dem Ausschalten durch geregeltes Zustellen einer Positioniereinrichtung solange weitergedreht, bis eine günstige Stellung für den Wiederstart erreicht ist. Der Motor kann so beim Wiederstart immer nach kurzem Drehwinkel wieder zünden oder gezündet werden. Der Verbrennungsmotor springt daher nach Abschaltphasen, wie sie z. B. bei Start/Stopp oder bei Hybridbetrieb in verschiedenen Situationen auftreten können, bei Einsatz der Erfindung bei jedem Wiederstart in annähernd gleicher kurzer Zeit an. Das Ansprechverhalten des Antriebs ist so auch nach hybridbedingten Motorabschaltungen immer gleich und so für den Fahrer gut abschätzbar.By the invention ensures that the internal combustion engine after is always positioned so that at least one Cylinder in a cheap Position to restart. For this purpose, the engine is switched off by controlled delivery of a positioning device as long continued to turn until a cheap Position for the Restart is achieved. The engine can always do so when restarting Ignite again after a short rotation angle or ignited become. The combustion engine therefore jumps after shutdown phases, as they are z. B. at start / stop or hybrid operation in different Situations can occur when using the invention at each restart in approximately the same a short time. The response of the drive is also after hybrid-related engine shutdowns always the same and so for the driver good estimate.
Die Erfindung ist geeignet für Brennkraftmaschinen mit beliebiger Zahl und Anordnung von Zylindern, sowohl für Benzinmotoren mit Kanaleinspritzung als auch für Benzin- oder Dieselmotoren mit Direkteinspritzung.The Invention is suitable for Internal combustion engines of any number and arrangement of cylinders, as well as Petrol engines with port injection as well as for gasoline or diesel engines with direct injection.
Weitere Vorteile und Ausgestaltungen gehen aus den Unteransprüchen und den Beschreibungen hervor. Nachfolgend werden die Fig. näher beschrieben. Dabei zeigen:Further Advantages and embodiments will become apparent from the dependent claims and the descriptions. The figures will be described in more detail below. Showing:

Jeder Zylinder hat pro zwei Umdrehungen eine günstige Startposition. Beim Vierzylinderreihenmotor R4 sind diese beispielsweise um 180° gegeneinander versetzt. Sie stimmen nicht mit den vier Vorzugslagen beim Stillsetzen überein. Bei anderen Zylinderzahlen ergeben sich je nach Zylinderanordnung entsprechende Vorzugspositionen beim Abschalten und günstige Startpositionen für den schnellen Wiederstart.Everyone Cylinder has a favorable starting position per two revolutions. At the Four-cylinder series motor R4 these are for example by 180 ° against each other added. They do not agree with the four preferred positions when stopping. For other numbers of cylinders depending on the cylinder arrangement corresponding Preferential positions when switching off and favorable starting positions for the fast Restart.
