Abstract
Description
Die vorliegende Erfindung betrifft eine Ladeeinrichtung, insbesondere einen Abgasturbolader für ein Kraftfahrzeug gemäß dem Oberbegriff des Anspruchs 1.The The present invention relates to a charging device, in particular an exhaust gas turbocharger for a motor vehicle according to the Preamble of claim 1.
Gattungsgemäße Ladeeinrichtungen sind hinlänglich bekannt und dienen der Leistungssteigerung von Kolbenmotoren, indem sie einen Luftmengen- und Kraftstoffdurchsatz pro Arbeitstakt erhöhen.generic Charging devices are well known and serve the Increase performance of piston engines by providing an air flow and increase fuel flow per stroke.
Aus
der
Ein großer Nachteil bei sich derzeit am Markt befindlichen Ladeeinrichtungen besteht darin, dass diese einem Abgas relativ viel Wärme entziehen und dadurch ein Katalysator in einem Abgasstrang, insbesondere während einer Startphase des Verbrennungsmotors, nur gering aufgeheizt wird und so seine volle Reinigungsleistung erst mit starker zeitlicher Verzögerung erreicht.One big disadvantage at present on the market Charging devices is that this relative to an exhaust gas extract a lot of heat and thereby a catalyst in one Exhaust line, especially during a launch phase of Internal combustion engine, only slightly heated and so its full Cleaning performance only after a considerable time delay reached.
Die vorliegende Erfindung beschäftigt sich mit dem Problem, für eine Ladeeinrichtung der gattungsgemäßen Art, eine verbesserte oder zumindest eine andere Ausführungsform anzugeben, welche sich einerseits insbesondere durch einen geringen abgasseitigen Wärmeentzug und andererseits durch ein geringes Gewicht auszeichnet.The The present invention addresses the problem of for a charging device of the generic type Art, an improved or at least another embodiment indicate, on the one hand, in particular by a low exhaust gas side Heat extraction and on the other hand by a low weight distinguished.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs 1 gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This Problem is inventively by the subject of the independent claim 1 solved. advantageous Embodiments are the subject of the dependent Claims.
Die vorliegende Erfindung beruht auf dem allgemeinen Gedanken, ein Turbinengehäuse einer Ladeeinrichtung, insbesondere eines Abgasturboladers für ein Kraftfahrzeug, zweischalig, das heißt aus einer Innenschale und einer Außenschale aufzubauen und einen zwischen der Innenschale und der Außenschale liegenden Zwischenraum zur Reduzierung der Wärmeleitung zumindest teilweise und/oder zumindest bereichsweise zu evakuieren. Durch die Evakuierung des Zwischenraums können eine Wärmeübertragung zwischen der Innenschale und der Außenschale und damit ein Wärmeentzug aus dem Abgas stark reduziert werden. Dies ist insbesondere während einer Kaltstartphase eines Verbrennungsmotors, bei welcher sich ein im Abgasstrang befindlicher Katalysator erst noch aufgeheizt werden muss, von großem Vorteil, da hier dem Abgas im Abgasturbolader keine Wärme entzogen wird und sich dadurch der Katalysator schneller aufheizt. Die schnellere Aufheizung des Katalysators erhöht dessen Reinigungswirkung und damit ein Emissionsverhalten des Verbrennungsmotors. Zugleich weist ein derartiges, zweischaliges, Turbinengehäuse im Vergleich zu herkömmlichen Turbinengehäusen ein deutlich reduziertes Gewicht auf, was ebenfalls dazu beiträgt, Kraftstoff und CO2-Emissionen zu reduzieren.The present invention is based on the general idea of constructing a turbine housing of a charging device, in particular of an exhaust gas turbocharger for a motor vehicle, with two shells, that is to say an inner shell and an outer shell, and a space lying between the inner shell and the outer shell for reducing the heat conduction at least partially and / or. or at least partially evacuate. By evacuating the gap heat transfer between the inner shell and the outer shell and thus a heat extraction from the exhaust gas can be greatly reduced. This is especially during a cold start phase of an internal combustion engine, in which a catalyst located in the exhaust system still has to be heated, of great advantage, since no heat is removed from the exhaust gas in the exhaust gas turbocharger and thereby heats up the catalyst faster. The faster heating of the catalyst increases its cleaning effect and thus an emission behavior of the internal combustion engine. At the same time, such a two-shell turbine housing has a significantly reduced weight compared to conventional turbine housings, which also helps to reduce fuel and CO 2 emissions.
Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung, sind die Innenschale und/oder die Außenschale aus Metall, insbesondere aus Stahlblech, ausgebildet. Derartige Stahlbleche bieten dabei den großen Vorteil, einerseits eine hohe Wärmeübertragung bieten zu können und andererseits im Vergleich zu Gehäuseteilen aus Gusswerkstoffen vergleichsweise leicht zu bauen. Durch eine Ausbildung der Innen- und/oder der Außenschale aus Metall kann darüber hinaus ein Berstverhalten bei einem Versagen des Turbinenrades günstig beeinflusst werden.at an advantageous embodiment of the invention Solution, are the inner shell and / or the outer shell made of metal, in particular made of sheet steel. such Steel sheets offer the big advantage, on the one hand to offer a high heat transfer and on the other hand compared to housing parts made of cast materials comparatively easy to build. By training the interior and / or the outer shell of metal may over it In addition, a bursting behavior at a failure of the turbine wheel low to be influenced.
