Magnesium-Hybrid-Turbomotor von Audi

Mit diesem Beitrag zeigt Audi einen Weg, wie der Leichtbauwerkstoff Magnesium durch spezielle konstruktive Detaillosungen und den Einsatz neuer warmfester Legierungen zukunftig auch in hochbelasteten Motoren eingesetzt werden kann. Durch gezieltes lokales Werkstoff-Engineering gelang es erstmals, einen Otto-Turbomotor mit einer spezifischen Leistung von 67 kW/l in Magnesium-Hybrid-Leichtbauweise darzustellen. Eine Besonderheit des im Druckgussverfahren hergestellten Kurbelgehauses stellt die Closed-deck-Bauweise dar, fur die ein grosserientaugliches Herstellungskonzept entwickelt wurde.

Magnesium-hybrid-turbo engine from Audi

In this paper, Audi demonstrates a way in which the lightweight material magnesium can, by means of special design details and the use of new alloys with improved strength at elevated temperatures, in future be employed in engines subject to high loads. By using carefully targeted localised materials engineering, it has proved possible for the first time to develop a four-stroke turbo engine with a specific power output of 67 kW/l with a magnesium hybrid lightweight structure. A special feature of the closed-deck, die-cast crankcase is that the manufacturing concept for it has been developed to be suitable for series production.

The crankcase of the new R4-TFSI engine generation from Audi

The market launch of Audi’s new 1.8-l-4V-TFSI engine from its EA888 engine series in early 2007 marked the start of a comprehensive renewal of its R4 petrol engines over the 1.8 l to 2.0 l capacity range. Over the coming years, the new EA888 engine series will gradually replace the highly successful EA113 series throughout the whole of the VW Group. In June 2007 a new 2.0-l-4V-TFSI engine will be added to the EA888 series. This paper deals with the development of the completely new crankcase for the EA888 engines, which was the result of an intensive collaboration with Eisenwerk Bruhl.The market launch of Audi’s new 1.8-l-4V-TFSI engine from its EA888 engine series in early 2007 marked the start of a comprehensive renewal of its R4 petrol engines over the 1.8 l to 2.0 l capacity range.
