Internal combustion engines with turbochargers can use fuel more efficiently by using direct injection and supercharging system technology: The term “Engine Downsizing” relates to the use of a smaller engine in order to achieve substantial reductions in CO2-emissions. In this case, the turbocharger speeds in excess of 200.000 rpm necessitate the use of sophisticated materials such as titanium aluminide. Manufacturers of turbochargers and their components need suitably adapted machine concepts, geared to the highly dynamic manufacturing processes used to produce large volumes of the complex radial compressors made of high-performance materials which are required. The Fraunhofer IPT systematically develops complex, automated manufacturing process chains which permit high volumes of highest possible quality radial compressors to be manufactured.
