Abstract
Driven by legislature and the limited reserves of raw materials, the question arises as to how further reductions in friction can be achieved in internal combustion engines. Besides the development of electric and hybrid drive systems, the task involves exploiting potential savings which lie in the optimisation of existing engine technology. The challenge is to explain physical relationships and to put the findings made by combining measurement and simulation into practice by choosing specific manufacturing methods. It is important to ensure that the selected techniques can be applied in global volume production.
Keywords: combustion engine, friction, emissions.
