Summary

For many years, exhaust-gas turbochargers have been state of the art for Diesel engines. But also for gasoline engines, as a downsizing measure, the turbocharger has reached the volume market of base engines. This increases the pressure on cost and weight. For Diesel engines additional variability in the flow path is being developed. The switching operation needs flaps, valves or variable guide vanes at the turbine or compressor. These switching devices have high demands on temperature and corrosion resistance and have to be integrated into the charging components due to space and mass restrictions. In order to develop economic, light and integrated solutions for ducts, housings and switching devices on the compressor side of the turbocharger, it makes sense to use plastic parts. But at high temperatures, only high performance plastic materials can fulfil the requirements on durability and dimensional stability.
