Description
Die vorliegende Erfindung betrifft eine Einrichtung zum Konditionieren eines Schmiermittels für eine Brennkraftmaschine. The present invention relates to a device for conditioning a lubricant for an internal combustion engine.
Bekannt ist der Einsatz unterschiedlichster Schmierstoffe oder Schmiermittel zur Schmierung, also Verringerung von Reibung und Verschleiß, sowie zur Kraftübertragung, Kühlung, Schwingungsdämpfung und Abdichtung. Zu ersterem Zweck bilden Schmieröle – als gewerblich wohl bedeutsamste Gruppe der Schmiermittel – zwischen bewegten Flächen einen Gleitfilm, wie er insbesondere zum Betrieb hydrodynamischer Gleitlager von Brennkraftmaschinen unerlässlich ist. It is known to use a wide variety of lubricants or lubricants for lubrication, so reducing friction and wear, as well as power transmission, cooling, vibration damping and sealing. For the first purpose, lubricating oils - as the most important group of lubricants in the industry - form a sliding film between moving surfaces, as is essential in particular for the operation of hydrodynamic sliding bearings of internal combustion engines.
Die nach dem Stand der Technik in Kraftfahrzeugen verbauten Viertaktmotoren weisen hierzu eine sogenannte Druckumlauf- oder Nasssumpfschmierung auf. Dabei wird das notwendige Schmiermittel unterhalb der Kurbelwelle in einer Ölwanne mitgeführt. Eine Ölpumpe saugt das Schmiermittel von dort an und befördert es in einem Schmiermittelkreislauf über die Schmierstellen zurück in die Ölwanne. The built according to the prior art in motor vehicles four-stroke engines have for this purpose a so-called pressure circulation or wet sump lubrication. The necessary lubricant is carried under the crankshaft in an oil pan. An oil pump sucks the lubricant from there and carries it in a lubricant circuit via the lubrication points back into the oil pan.

Die Erfindung stellt eine Einrichtung zum Konditionieren eines Schmiermittels für eine Brennkraftmaschine gemäß Anspruch 1 bereit. Dieser Ansatz fußt auf dem Grundgedanken, eine fluidische Verbindung des Brennkraftmaschine-Kühlflüssigkeit-Kreislaufs mit der Ölwanne zur Erwärmung oder Kühlung des Motoröls in der Ölwanne zu schaffen. The invention provides a device for conditioning a lubricant for an internal combustion engine according to
Die Erfindung basiert dabei auf der Erkenntnis, dass es bei extremen Einsatzbedingungen, wie Niedertemperatur-Start bzw. -Betrieb oder Hochtemperatur-Start bzw. -Betrieb von Vorteil sein kann, das im zu betreibenden System befindliche Öl zu konditionieren bzw. es an die optimalen Arbeitstemperaturen schnellstmöglich anzugleichen. The invention is based on the recognition that under extreme conditions of use, such as low-temperature startup or operation or high-temperature startup or operation, it may be advantageous to condition the oil in the system to be operated or to optimize it Adjust working temperatures as quickly as possible.
Ein Vorzug der vorgeschlagenen Lösung liegt darin, dass bei extrem warmen bzw. extrem kalten Umgebungstemperaturen das Schmiermittel im Schmiermittelkreislauf in vorteilhafter Weise konditioniert wird. Dies hat zum Ziel, die Förderbarkeit, das Schmierverhalten und die Leckage-Verluste zu verbessern. Durch die thermische Kopplung des Schmiermittelkreislaufs mit dem Brennkraftmaschine-Kühlflüssigkeit-Kreislauf wird dieser ebenfalls in vorteilhafter Weise konditioniert. An advantage of the proposed solution is that at extremely warm or extremely cold ambient temperatures, the lubricant is conditioned in the lubricant circuit in an advantageous manner. This has the goal to improve the conveyability, the lubrication behavior and the leakage losses. Due to the thermal coupling of the lubricant circuit with the engine coolant circuit this is also conditioned in an advantageous manner.
Beispielsweise in einem kalten Land kann das Öl eine so hohe Viskosität annehmen, dass es nur schwer zu pumpen ist. Hier unterstützt das beschriebene System den Aufheizprozess des Öles in der Ölwanne, sodass dieses förderbar wird. For example, in a cold country, the oil may become so viscous that it is difficult to pump. Here, the described system supports the heating process of the oil in the oil sump so that it can be conveyed.
Andererseits kann in einem heißen Land das beschriebene System dazu genutzt werden, das heiße Öl in der Ölwanne vor dem Ansaugen durch die Ölpumpe abzukühlen und hierdurch weniger Leck-Verluste zu erreichen. Zudem kann hierdurch die Lebensdauer des Schmiermittels erhöht werden. On the other hand, in a hot country, the described system can be used to cool the hot oil in the oil sump from being sucked by the oil pump, and thus less leakage. To achieve losses. In addition, this can increase the life of the lubricant.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Patentansprüchen angegeben. Insbesondere ein Einbinden des beschriebenen Systems in einen mit dem Kühlkreislauf gekoppelten Standheiz- oder Aufheizkreislauf ist denkbar. So kann eine Heizeinrichtung, insbesondere eine Standheizung, zur Unterstützung des Wärmeeintrages in den Brennkraftmaschine-Kühlflüssigkeit-Kreislauf dienen. Hierbei wird dann das System nur temporär genutzt und kann dann wahlweise abgeschaltet werden. Further advantageous embodiments of the invention are specified in the dependent claims. In particular, incorporation of the described system in a coupled to the cooling circuit auxiliary heating or heating circuit is conceivable. Thus, a heating device, in particular a heater, serve to support the heat input into the engine coolant circuit. In this case, the system is only used temporarily and can then be switched off optionally.
Für das beschriebene System kann die Ölwanne mit einem Doppelboden ausgeführt werden. Dieser kann beispielsweise direkt als Guss-Teil bzw. Schweißbaugruppe ausgeführt werden oder als separates Bauteil angebracht werden. For the described system, the oil pan can be designed with a double bottom. This can for example be performed directly as a cast part or welded assembly or attached as a separate component.
Ferner kann dieser Doppelboden bzw. das Konditioniermedium führende Element durch eine zusätzlich eingebrachte Geometrie so gestaltet werden, dass die innere und/oder äußere Oberfläche vergrößert wird, sodass der Wärmeübergang verbessert wird. Furthermore, this double floor or the conditioning medium leading element can be designed by an additionally introduced geometry so that the inner and / or outer surface is increased, so that the heat transfer is improved.
Zudem kann der Medium führende Bereich als Spirale bzw. gewundenes Rohr ausgeführt werden. In addition, the medium-leading region can be performed as a spiral or tortuous tube.
Schließlich kann der das Medium führende Bereich als Wärmetauscher ausgeführt werden. Hierbei wird der Wärmetauscher mit dem Konditioniermedium durchströmt. Des Weiteren kann der Wärmetauscher so angeordnet werden, dass der Saugbereich der Ölpumpe direkt hinein oder herüber ragt, sodass das angesaugte Öl durch den Wärmetauscher gefördert wird. Finally, the medium-carrying region can be designed as a heat exchanger. In this case, the heat exchanger is flowed through by the conditioning medium. Furthermore, the heat exchanger can be arranged so that the suction region of the oil pump projects directly into or out, so that the sucked oil is conveyed through the heat exchanger.
Der Wärmetauscher kann so angeordnet werden, dass dieser als Schwallwand dient, um das Öl bei etwaigen Beschleunigungen führen zu können. Des Weiteren kann der als Schwallwand angeordnete Wärmetauscher so angeordnet werden, dass das aufgeschäumte Öl in der Ölwanne beruhigt wird. The heat exchanger can be arranged so that it serves as a baffle, in order to be able to lead the oil at any acceleration. Furthermore, the heat exchanger disposed as a baffle can be arranged so that the foamed oil is calmed in the oil pan.
Der Wärmetauscher kann auch so angeordnet werden, dass in oder über diesem der Ölrücklauf in die Ölwanne positioniert wird und das Öl entgegen der resultierenden Strömungsrichtung beruhigt wird. The heat exchanger can also be arranged so that in or above this the oil return is positioned in the oil pan and the oil is calmed counter to the resulting flow direction.
Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und werden im Folgenden näher beschrieben. Embodiments of the invention are illustrated in the drawings and will be described in more detail below.
