Housing for water-cooled exhaust gas turbocharger
Achieve significant reductions in exhaust gas temperatures with Handtmann
The new BMW 3-cylinder engine is fitted with the world’s first water-cooled exhaust gas turbocharger made entirely from aluminium. This provides plenty of scope for design. Both the exhaust side and the water side in interaction with the component strength calculation have been optimised so that the reduction in the wall heat flow produces minimal extra cooling effort. This design developed by Handtmann combines significant cost and weight savings with a considerable CO2 potential, despite additional cooling effort. Another important side effect are the low exhaust gas temperatures upstream of the catalytic converter of well below 850 °C compared to the non-cooled exhaust gas turbocharger made from steel. This ensures that catalytic converter ageing is as good as ruled out.
How the water-cooled exhaust gas turbocharger for 3-cylinder engines works
- Exhaust gas turbine housing incl. assembly wastegate flap
- Exhaust gas inlet temperature up to 1,050 °C
- Significant protection of the catalytic converter
- Weight and cost reduction by substitution of cast steel
From development to large-scale production, Handtmann offers complex supercharging systems for a wide range of applications.
