Description
Die Erfindung betrifft ein Verfahren zum Betreiben eines Turboladers, insbesondere eines Abgasturboladers, gemäß dem Oberbegriff des Patentanspruchs 1. Des weiteren betrifft die Erfindung einen Turbolader, insbesondere einen Abgasturbolader, gemäß dem Oberbegriff des Patentanspruchs 9.The Invention relates to a method for operating a turbocharger, in particular an exhaust gas turbocharger, according to the preamble of the claim 1. Furthermore, the invention relates to a turbocharger, in particular an exhaust gas turbocharger, according to the preamble of claim 9.
Turbolader,
insbesondere Abgasturbolader, werden zur Leistungssteigerung bei
Brennkraftmaschinen verwendet. So offenbart zum Beispiel die
Moderne Turbolader verdichten innerhalb des Verdichters einen Luftmassenstrom auf derart hohe Drücke, dass am Austritt des Verdichters, insbesondere am Austritt des Verdichterrads, Temperaturen von mehreren hundert Grad Kelvin erreicht werden. Das Verdichterrad des Verdichters ist vorzugsweise aus einer Aluminiumlegierung gebildet, wobei bei Temperaturen von mehreren hundert Grad Kelvin am Verdichterrad das Problem auftritt, dass die Aluminiumlegierung des Verdichterrads speziell am Außendurchmesser einen dauerhaften Festigkeitsverlust erleidet (thermische Alterung). Dies kann zu einem Versagen des Verdichterrads und damit zu einer verkürzten Lebensdauer desselben führen. Es ist demnach wünschenswert, die Temperaturen im Bereich des Verdichterradaustritts zu beschränken.modern Turbochargers compress air mass flow within the compressor to such high pressures, that at the outlet of the compressor, in particular at the outlet of the compressor wheel, Temperatures of several hundred degrees Kelvin can be achieved. The Compressor wheel of the compressor is preferably made of an aluminum alloy formed at temperatures of several hundred degrees Kelvin at Compressor wheel the problem occurs that the aluminum alloy the compressor wheel, especially on the outer diameter of a permanent Strength loss suffers (thermal aging). This can be too a failure of the compressor wheel and thus to a shortened life lead the same. It is therefore desirable to limit the temperatures in the area of the compressor wheel outlet.
Hiervon ausgehend liegt der vorliegenden Erfindung das Problem zugrunde, einen neuartigen Turbolader, insbesondere einen neuartigen Abgasturbolader, und ein Verfahren zum Betreiben eines Turboladers, insbesondere eines Abgasturboladers, zu schaffen.Of these, Based on the present invention, the problem is based a novel turbocharger, in particular a novel exhaust gas turbocharger, and a method for operating a turbocharger, in particular an exhaust gas turbocharger to create.
Dieses Problem wird durch ein Verfahren zum Betreiben eines Turboladers gemäß Patentanspruch 1 gelöst. Erfindungsgemäß wird vor dem Eintritt des Verdichtermassenstroms (im folgenden auch als zweiter Luftmassenstrom bezeichnet), insbesondere des Frischluftmassenstroms, in den Verdichter des Turboladers in den zweiten Luftmassenstrom ein Fluid injiziert, wobei das injizierte Fluid im Verdichter verdunstet und so eine Kühlung insbesondere eines Verdichterrads des Verdichters bewirkt. Desweiteren wirkt sich diese Maßnahme auch auf den Nachleitapparat aus, wo Ölablagerungen vermieden werden. Außerdem ist eine günstige Beeinflussung hinsichtlich einer NOx-Bildung festzustellen.This Problem is solved by a method for operating a turbocharger according to claim 1 solved. According to the invention is the entry of the compressor mass flow (hereinafter also as the second Referred to air mass flow), in particular the fresh air mass flow, in the compressor of the turbocharger in the second air mass flow injected a fluid, wherein the injected fluid evaporates in the compressor and so a cooling in particular causes a compressor wheel of the compressor. Furthermore, it works this measure also on the Nachleitapparat where oil deposits are avoided. Besides that is a cheap one Determine the influence of NOx formation.
Im Sinne der hier vorliegenden Erfindung wird vorgeschlagen, in den durch den Verdichter des Turboladers zu verdichtenden, zweiten Luftmassenstrom vor dem Eintritt desselben in den Verdichter ein Fluid zu injizieren, wobei das Fluid innerhalb des Verdichters verdunstet und vorzugsweise vor Erreichen des Austritts des Verdichters bzw. des Verdichterrads vollständig (aber auch teilweise würde helfen) verdunstet ist. Hierdurch kann eine Kühlung des Verdichters bzw. des Verdichterrads bewirkt werden. Durch Überschreitung der zulässigen Temperatur des Verdichterrads bewirkte Festigkeitsminderungen desselben können so auf einfache und sichere Art und Weise vermieden werden.in the For the purposes of the present invention, it is proposed in the through the compressor of the turbocharger to be compressed, second air mass flow to inject fluid into the compressor before entering it, wherein the fluid within the compressor evaporates, and preferably before reaching the outlet of the compressor or the compressor wheel completely (but also partially help) has evaporated. This can be a cooling of the compressor or the compressor wheel are effected. By exceeding the permissible temperature of the Verdichterrads caused deterioration of the same can so be avoided in a simple and secure way.
Nach einer vorteilhaften Weiterbildung der Erfindung wird das Fluid derart in den zweiten Luftmassenstrom injiziert wird, dass der Anteil des Fluids am Gesamtmassenstrom aus zweitem Luftmassenstrom und Fluid vorzugsweise bei in etwa 1 % liegt.To In an advantageous embodiment of the invention, the fluid is such is injected into the second air mass flow that the proportion of Fluids on the total mass flow of second mass air flow and fluid preferably at about 1%.
Nach einer weiteren vorteilhaften Weiterbildung der Erfindung wird das Fluid vor dem Injizieren desselben in den zweiten Luftmassenstrom verdichtet und derart erhitzt, dass das Fluid beim Injizieren eine Temperatur aufweist, die unter den Umgebungsbedingungen des Injizierens 20K bis 100K oberhalb der Siedetemperatur des Fluids liegt.To a further advantageous embodiment of the invention is the Fluid prior to injecting it into the second mass air flow compressed and heated so that the fluid when injecting a Temperature that under the ambient conditions of Injizierens 20K to 100K above the boiling temperature of the fluid.
Der erfindungsgemäße Turbolader ist im unabhängigen Patentanspruch 9 definiert.Of the Turbocharger according to the invention is independent Defended claim 9.
Bevorzugte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung. Ein Ausführungsbeispiel der Erfindung wird, ohne hierauf beschränkt zu sein, an Hand der Zeichnung näher erläutert.
