Abstract
Description
Die Erfindung betrifft eine Brennkraftmaschine mit einem Motorblock mit einer Ölwanne und mit einem Abgasrohr für die Verbrennungsgase.The invention relates to an internal combustion engine with an engine block with an oil pan and with an exhaust pipe for the combustion gases.
Ziel jeder Motorenentwicklung ist es, den effektiven Wirkungsgrad einer Brennkraftmaschine weiter zu verbessern. Dies kann beispielsweise durch die Minimierung der Reibungsverluste geschehen, die insbesondere von dem verwendeten Motoröl und dessen Viskosität abhängen.The aim of every engine development is to determine the effective efficiency of a To further improve the internal combustion engine. This can be done, for example, by Minimization of the friction losses happen, in particular from the one used Depending on engine oil and its viscosity.
Aufgabe der Erfindung ist es eine Brennkraftmaschine mit reduzierten Reibungsverlusten durch Einflussnahme auf die Ölviskosität zur Verfügung zu stellen.The object of the invention is an internal combustion engine with reduced To provide friction losses by influencing the oil viscosity.
Die Lösung dieser Aufgabe wird in Verbindung mit den Oberbegriffsmerkmalen erfindungsgemäß durch die im kennzeichnenden Teil des Patentanspruches 1 angegebene technische Lehre vermittelt.The solution to this problem is in connection with the generic terms according to the invention in the characterizing part of claim 1 communicates the specified technical teaching.
Dadurch, dass die Brennkraftmaschine mit einem Wärmetauscher zur Erwärmung des Motoröls durch die Temperatur der Verbrennungsgase ausgebildet ist, lässt sich die Temperatur des Motoröls und damit dessen Viskosität gezielt beeinflussen und die Reibungsverluste im Motor wesentlich verringern. Die Möglichkeit zur Beeinflussung der Temperatur des Motoröls führt zum einen zu einer schnelleren Erwärmung des Motoröls und damit des gesamten Motors und führt damit zu einer Optimierung des gesamten Abgasverhaltens. Zum anderen kann im Teillastbereich einer Brennkraftmaschine, in dem die Öltemperatur gewöhnlich absinkt, das Motoröl auf einer optimalen Temperatur gehalten werden. Durch die vorteilhafte Anordnung eines Wärmetauschers zur Erwärmung des Motoröls wird aber nicht nur ein größeres Potential für Kraftstoffeinsparungen geschaffen, es lässt sich weiterhin auch die Abgastemperatur herabsetzen, was sich insbesondere für NOX-Speicherkonzepte, wie sie bei Brennkraftmaschinen mit Benzindirekteinspritzung zum Einsatz kommen, als weiterer Vorteil erweist. Because the internal combustion engine is designed with a heat exchanger for heating the engine oil by the temperature of the combustion gases, the temperature of the engine oil and thus its viscosity can be influenced in a targeted manner and the friction losses in the engine can be significantly reduced. On the one hand, the possibility of influencing the temperature of the engine oil leads to faster heating of the engine oil and thus of the entire engine and thus leads to an optimization of the overall exhaust behavior. On the other hand, in the partial load range of an internal combustion engine, in which the oil temperature usually drops, the engine oil can be kept at an optimal temperature. The advantageous arrangement of a heat exchanger for heating the engine oil not only creates greater potential for fuel savings, it also allows the exhaust gas temperature to be reduced, which is particularly useful for NO x storage concepts such as those used in internal combustion engines with gasoline direct injection proves another advantage.
Weitere vorteilhafte Ausgestaltungen des Gegenstandes der Erfindung ergeben sich mit und in Kombination aus den nachfolgenden Unteransprüchen.Further advantageous refinements of the subject matter of the invention result from and in combination from the following subclaims.
Gemäß einer besonders bevorzugten Ausführungsform des Gegenstandes der Erfindung ist der Wärmetauscher in der Ölwanne einer Brennkraftmaschine angeordnet, sodass der gesamte Ölvorrat in einer Ölwanne einer Brennkraftmaschine auf einer optimalen Temperatur gehalten werden kann, die etwa zwischen 110°C und 130°C liegt.According to a particularly preferred embodiment of the subject of Invention, the heat exchanger is arranged in the oil pan of an internal combustion engine, so that the entire oil supply in an oil pan of an internal combustion engine on one optimal temperature can be maintained, which is between 110 ° C and 130 ° C lies.
Zur Energieversorgung des Wärmetauschers ist im Abgasrohr eine Abgasklappe vorgesehen und in Austrittsrichtung der Abgase vor der Abgasklappe eine Abzweigung mit einer angeschlossenen Rohrleitung, durch die die Abgase bei einer teilweise geschlossenen Abgasklappe durch den Wärmetauscher geleitet werden. Durch diese Anordnung lässt sich die Motoröltemperatur in besonders einfacher und kostengünstiger Art und Weise unter Ausnutzung der sonst als Abwärme abgegebenen Energie schneller auf eine gewünschte Temperatur bringen und im Teillast-Bereich auf dieser Temperatur halten.There is an exhaust flap in the exhaust pipe to supply energy to the heat exchanger provided and a branch in the outlet direction of the exhaust gases in front of the exhaust flap with a connected pipeline through which the exhaust gases at a partial closed flap are passed through the heat exchanger. Through this The engine oil temperature can be arranged in a particularly simple and economical manner Way faster using the energy otherwise given off as waste heat bring to a desired temperature and in the partial load range at this temperature hold.
Das abgezweigte und durch den Wärmetauscher geleitete Abgas wird bevorzugterweise anschließend durch eine Abgasrückführung wieder hinter der Abgasklappe in das Abgasrohr zurückgeführt.The branched off gas and passed through the heat exchanger is preferred then through an exhaust gas recirculation behind the exhaust flap in the Exhaust pipe returned.
Besonders vorteilhaft ist die Ausgestaltung der Steuerung der Abgasklappe mit einer automatischen Stellvorrichtung, die pneumatisch, elektrisch oder mechanisch ausgeführt sein kann, wobei eine pneumatische Stellvorrichtung ihre Stellkraft aus einer Unterdruckdose beziehen kann, die über einen Unterdruckschlauch mit Unterdruck, beispielsweise aus dem Ansaugtrakt einer Brennkraftmaschine, versorgt wird. Bei Volllast einer Brennkraftmaschine ist die Abgasklappe vollständig geöffnet, sodass der Wärmetauscher nicht von heißem Abgas durchströmt wird, wohingegen die Abgasklappe im Teillast-Bereich teilweise geschlossen ist und für die Aufrechterhaltung der gewünschten Öltemperatur sorgt.The configuration of the control of the exhaust flap with a is particularly advantageous automatic actuator that is pneumatic, electric or mechanical can be, wherein a pneumatic actuator its actuating power from a Vacuum box, which can be connected to a vacuum hose with vacuum, for example from the intake tract of an internal combustion engine. at At full load of an internal combustion engine, the exhaust flap is fully open, so that Hot exhaust gas does not flow through the heat exchanger, whereas the Exhaust flap in the partial load range is partially closed and for maintenance the desired oil temperature.
Gemäß einer weiteren vorteilhaften Ausführungsform der Erfindung kann der Wärmetauscher auch außerhalb der Brennkraftmaschine als separates Bauteil ausgeführt sein, wozu dann allerdings entsprechende Abzweige bzw. Umleitungen im Ölkreislauf der Brennkraftmaschine vorgesehen werden müssen.According to a further advantageous embodiment of the invention, the Heat exchanger outside the internal combustion engine as a separate component be executed, for which purpose, however, appropriate branches or diversions in the Oil circuit of the internal combustion engine must be provided.
