Silica-Aerogels for exhaust systems a new material for thermal insulation

Abstract

The catalyst in the exhaust system works more effective, when the temperature is high enough (approximately 400°C). The temperature till the entrance of the catalyst. Developing Insulation materials for such temperatures with good mechanical properties is therefore a real challenge. We propose to combine quartz glass felts with inorganic silica aerogels to manufacture a new types of generic exhaust system of engines.
