Work Package 4: New materials for higher engine efficiency

Objectives

Thermodynamic concepts of exhaust gas treatment, reduction of specific fuel oil or intensified usage of exhaust gas energy go along with higher component temperatures and mechanical loads. The objective of this Work package is to develop the use of appropriate material for optimized combustion engines. The components are the cylinder head and the turbocharger turbine casting. These components are cyclic loaded by mechanical and thermal loads.

New materials and design for cylinder heads

• Improvement of thermomechanical cycle resistance of factor 2 under increased temperature of 50 K 
• decreased weight of cylinder head of 20%

New materials for the turbocharger turbine casing.

Improvement of thermomechanical cycle resistance under increased temperature of 70 K under corrosion  environment.
