The field of tribology is an interdisciplinary science with the potential to make a significant contribution to reducing CO2 emissions. The two main areas of focus in this regard are the reduction of friction (energy efficiency) and the enhancement of durability (resource efficiency). The targeted optimisation of friction properties and wear resistance, for instance, has the capacity to increase the efficiency and reliability of engines.

The Internal Engine Tribology working group at the ITV is conducting research into the optimisation of the tribology of the piston group, which consists of pistons, piston rings and cylinder liners.The focus of the research is various methods for reducing friction and wear tendency, including microstructures, coatings and mould adaptations. The target variables and boundary conditions, which include piston speed, combustion chamber pressure and gas and component temperatures, are analysed using friction force measurements on the test engine. The knowledge gained from this research will further optimise existing processes and improve their sustainability.
