Description

2 AT 500 388 B12 AT 500 388 B1

Die Erfindung betrifft ein Verfahren zum Betreiben einer Brennkraftmaschine, insbesondere eines Hybridfahrzeuges, welche zumindest einen Abgasturbolader und zumindest eine Ölpumpe aufweist. 5 Insbesondere bei Hybridfahrzeugen mit einer Brennkraftmaschine mit Turbolader ist die Schmierung des Turboladers beim Abschaltvorgang der Brennkraftmaschine nach einer Betriebsphase mit hoher Drehzahl, beispielsweise im sogenannten Start-Stop-Betrieb, kritisch, da die, beispielsweise durch die Brennkraftmaschine angetriebene, Ölpumpe nach dem Abstellen kein Schmieröl mehr fördert, obwohl der Turbolader noch mit hoher Drehzahl laufen kann. 10The invention relates to a method for operating an internal combustion engine, in particular a hybrid vehicle, which has at least one exhaust gas turbocharger and at least one oil pump. Especially in hybrid vehicles with an internal combustion engine with turbocharger, the lubrication of the turbocharger during shutdown of the engine after a phase of operation at high speed, for example, in the so-called start-stop operation, critical because the, for example, driven by the engine, oil pump after stopping no Lubricating oil promotes more, although the turbocharger can still run at high speed. 10

Aus der JP 2002-276383 A ist eine Schmiereinrichtung für eine Brennkraftmaschine mit einem Turbolader bekannt. Um die Schmierstellen des Turboladers auch bei Abstellen der Brennkraftmaschine ausreichend mit Schmieröl zu versorgen, ist eine Hilfsölpumpe vorgesehen, welche in einer Bypassleitung der Hauptölpumpe angeordnet ist. Die Hilfsölpumpe wird im Falle 15 eines kurzzeitigen Abstellens der Brennkraftmaschine zur Versorgung der Lager des Turboladers mit Schmieröl verwendet. Die JP 2001-241313 A offenbart eine ganz ähnliche Anordnung.From JP 2002-276383 A a lubricating device for an internal combustion engine with a turbocharger is known. In order to supply the lubricating points of the turbocharger sufficiently even when the internal combustion engine with lubricating oil, an auxiliary oil pump is provided, which is arranged in a bypass line of the main oil pump. The auxiliary oil pump is used in case 15 of a short-term shutdown of the internal combustion engine to supply the bearings of the turbocharger with lubricating oil. JP 2001-241313 A discloses a quite similar arrangement.

Aus der US 2004/0108149 A1 ist ein Hybridfahrzeug mit einem Elektromotor und einer Brennkraftmaschine bekannt. Nach Abschalten der Brennkraftmaschine treibt der Elektromotor die 20 Kurbelwelle bei einer Leerlaufdrehzahl für eine vorbestimmte Zeitdauer an. Durch die Kurbelwelle wird dabei eine Ölpumpe angetrieben, welche Schmierstellen von mechanischen Teilen mit Öl versorgt.From US 2004/0108149 A1 a hybrid vehicle with an electric motor and an internal combustion engine is known. After switching off the internal combustion engine, the electric motor drives the crankshaft 20 at an idle speed for a predetermined period of time. By the crankshaft while an oil pump is driven, which supplies lubrication points of mechanical parts with oil.

Die JP 53-081842 A offenbart ein Schmiersystem für einen Turbolader einer Brennkraftmaschi-25 ne, bei dem vorgesehen ist, dass der Turbolader sowohl vor dem Start der Brennkraftmaschine, als auch nach dem Abstellen der Brennkraftmaschine mit Öl versorgt wird.JP 53-081842 A discloses a lubrication system for a turbocharger of an internal combustion engine, in which it is provided that the turbocharger is supplied with oil both before starting the internal combustion engine and after stopping the internal combustion engine.

Aufgabe der Erfindung ist es, diese Nachteile zu vermeiden und eine ausreichende Schmierung des Turboladers beim Abstellvorgang zu ermöglichen. 30The object of the invention is to avoid these disadvantages and to allow adequate lubrication of the turbocharger during shutdown. 30

Erfindungsgemäß wird dies dadurch erreicht, dass bei einem auf eine Hochlast- oder Volllastphase der Brennkraftmaschine folgenden Abschaltbefehl die Ölpumpe eine Mindestnachlaufdauer lang betrieben wird und dass die Mindestnachlaufdauer in Abhängigkeit zumindest eines Betriebsparameters, vorzugsweise der Drehzahl des Turboladers, des Drehmomentes oder der 35 Einspritzmenge der Brennkraftmaschine, vorzugsweise zum Zeitpunkt des Abschaltbefehls, ermittelt wird.According to the invention, this is achieved by operating the oil pump for a minimum follow-up duration in a shutdown command following a high-load or full-load phase of the internal combustion engine, and in that the minimum follow-up duration depends on at least one operating parameter, preferably the rotational speed of the turbocharger, the torque or the injection quantity of the internal combustion engine , preferably at the time of the shutdown command is determined.

Insbesondere bei einer durch die Kurbelwellen in der Brennkraftmaschine angetriebene Ölpumpe ist es besonders vorteilhaft, wenn die Brennkraftmaschine für zumindest eine Mindestnach-40 laufdauer bei Teillast oder Leerlauf betrieben wird. Bei Verwendung einer elektrisch antreibba-ren Ölpumpe dagegen kann vorgesehen sein, dass die Ölpumpe nach Abschalten der Brennkraftmaschine zumindest eine Mindestnachlaufdauer lang betrieben wird. Dadurch wird eine ausreichende Schmierung der Lager der Abgasturbine gewährleistet. 45 Die Erfindung wird im Folgenden anhand der Figur näher erläutert.In particular, in an oil pump driven by the crankshafts in the internal combustion engine, it is particularly advantageous if the internal combustion engine is operated for at least a minimum after-40 running time at partial load or idling. When using an electrically antreibba-Ren oil pump, however, it can be provided that the oil pump is operated after switching off the engine at least a minimum Nachlaufdauer long. This ensures adequate lubrication of the bearings of the exhaust gas turbine. 45 The invention will be explained in more detail below with reference to FIG.

Die Figur zeigt schematisch eine Brennkraftmaschine 1 für eine Hybridfahrzeug, mit einem Einlassstrang 2 und einem Auslassstrang 3. Im Einlass- und Auslassstrang 2, 3 ist ein Abgasturbolader 4 angeordnet, dessen Lager 5 durch eine von der Kurbelwelle 6 der Brennkraftma-50 schine 1 angetriebene Ölpumpe 7 mit Schmieröl versorgt werden. Insbesondere bei Hybridfahrzeugen treten Betriebsphasen auf, bei denen die Brennkraftmaschine 1 unmittelbar nach einem Volllastbetrieb abgeschaltet wird. Da die Ölpumpe 7 normalerweise mit den anderen Nebenantrieben über die Kurbelwelle 6 betrieben wird, liefert sie nach dem Abstellen der Brennkraftmaschine kein Schmieröl mehr zu den Lagern 5 des Abgasturboladers 4, obwohl der Abgasturbo-55 lader 4 noch mit sehr hoher Drehzahl umlaufen kann. Dadurch kann es zu einem Schmieröl-The figure shows schematically an internal combustion engine 1 for a hybrid vehicle, with an intake manifold 2 and an outlet 3. In the inlet and outlet 2, 3, an exhaust gas turbocharger 4 is arranged, the bearing 5 by one of the crankshaft 6 of the internal combustion engine 50 driven machine 1 Oil pump 7 are supplied with lubricating oil. Especially in hybrid vehicles operating phases occur in which the internal combustion engine 1 is switched off immediately after a full load operation. Since the oil pump 7 is normally operated with the other auxiliary drives via the crankshaft 6, it delivers after stopping the engine no more lubricating oil to the bearings 5 of the exhaust gas turbocharger 4, although the turbocharger 55 loader 4 can still circulate at very high speed. This can lead to a lubricating oil

Um dies zu vermeiden, wird aufgrund des Profils leistungsspezifischer Motorparameter (Moment, Einspritzmenge), des Drehzahlprofils der Brennkraftmaschine 1 und/oder der Drehzahl des Abgasturboladers 4 eine Mindestnachlaufdauer ermittelt, ab der eine zerstörungsfreie Abschaltung möglich ist.
