Description
Die Erfindung betrifft einen Abgasturbolader für eine Verbrennungskraftmaschine gemäß dem Oberbegriff des Patentanspruchs 1. Des Weiteren betrifft die Erfindung ein Verfahren zum Betrieb eines Abgasturboladers gemäß dem Oberbegriff des Patentanspruchs 10.The invention relates to an exhaust gas turbocharger for an internal combustion engine according to the preamble of
Die
Der Erfindung liegt die Aufgabe zu Grunde, einen gegenüber dem Stand der Technik verbesserten, insbesondere effektiveren Abgasturbolader für eine Verbrennungskraftmaschine und ein verbessertes Verfahren zum Betrieb eines solchen Abgasturboladers anzugeben.The invention is based on the object to provide a comparison with the prior art improved, in particular more effective exhaust gas turbocharger for an internal combustion engine and an improved method for operating such an exhaust gas turbocharger.
Hinsichtlich des Abgasturboladers für eine Verbrennungskraftmaschine wird die Aufgabe erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale gelöst.With regard to the exhaust gas turbocharger for an internal combustion engine, the object is achieved by the features specified in

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Beim Abgasturbolader für eine Verbrennungskraftmaschine mit einem Getriebe, wobei Abgasturbolader und Verbrennungskraftmaschine in einem Schmiermittelkreislauf angeordnet sind, ist erfindungsgemäß ein Wärmetauscher in einem Abgasgehäuse des Abgasturboladers angeordnet und von einem Schmiermittel durchströmbar. Somit kann eine solche Anordnung mit geringem Aufwand in einem bestehenden System integriert werden.In the exhaust gas turbocharger for an internal combustion engine with a transmission, wherein exhaust gas turbocharger and internal combustion engine are arranged in a lubricant circuit, a heat exchanger according to the invention is arranged in an exhaust gas housing of the exhaust gas turbocharger and can be flowed through by a lubricant. Thus, such an arrangement can be integrated with little effort in an existing system.
Mittels der Nutzung eines bereits vorhandenen Ölpfads der Verbrennungskraftmaschine zur Schmiermittelversorgung des Abgasturboladers kann eine Erwärmung des Schmiermittels schnell und direkt erfolgen. Bedingt durch die geringe räumliche Entfernung zwischen Abgasturbolader und Verbrennungskraftmaschine und/oder Getriebe kann die Erwärmung des Schmiermittels mit einem besonders geringen Aufwand erfolgen.By using an existing oil path of the internal combustion engine to supply lubricant to the exhaust gas turbocharger heating of the lubricant can be done quickly and directly. Due to the small spatial distance between exhaust gas turbocharger and internal combustion engine and / or gearbox, the heating of the lubricant can be done with a very low cost.
Besonders vorteilhafterweise ist eine effiziente Schmiermittelversorgung der Verbrennungskraftmaschine mit niedrigviskosem erwärmten und somit leichter fließendem Schmiermittel ermöglicht, wodurch ein mechanischer Verschleiß der Verbrennungskraftmaschine verringert ist.Particularly advantageously, an efficient supply of lubricant to the internal combustion engine with low viscosity heated and thus easier flowing lubricant is possible, whereby a mechanical wear of the internal combustion engine is reduced.
Beim Verfahren zum Betrieb eines Abgasturboladers für eine Verbrennungskraftmaschine wird erfindungsgemäß ein Schmiermittel durch einen Schmiermittelkanal im Abgasturbolader geleitet. Dabei wird insbesondere ein unterhalb eines vorgebbaren Temperaturwertes temperiertes Schmiermittel durch den Schmiermittelkanal geleitet, wobei eine Schmiermittelzufuhr in den Schmiermittelkanal oberhalb einer vorgebbaren Temperatur des Abgasgehäuse des Abgasturboladers mittels eines Absperrventils unterbrochen und der Schmiermittelkanal mittels eines Belüftungsventils entleert wird. Dadurch ist besonders vorteilhafterweise eine Warmlaufphase der Verbrennungskraftmaschine verkürzt und ein daraus resultierender Schadstoffausstoß ist signifikant verringert. Weiterhin kann der Schmiermittelkanal entleert werden, so dass das Schmiermittel sicher vor lokaler Überhitzung im Abgasturbolader geschützt ist.In the method for operating an exhaust gas turbocharger for an internal combustion engine, a lubricant is passed through a lubricant channel in the exhaust gas turbocharger according to the invention. In this case, in particular, a tempered below a predetermined temperature value lubricant is passed through the lubricant passage, wherein a lubricant supply is interrupted in the lubricant passage above a predetermined temperature of the exhaust gas housing of the exhaust gas turbocharger by means of a shut-off valve and the lubricant passage is emptied by means of a ventilation valve. As a result, a warm-up phase of the internal combustion engine is particularly advantageously shortened and resulting pollutant emissions are significantly reduced. Furthermore, the lubricant channel can be emptied, so that the lubricant is safely protected against local overheating in the exhaust gas turbocharger.
