Mahle sees potential to reduce CO2 in the WLTC by directly developing tribology of pistons, piston rings and piston pins at 2.5 %. When used in combination with low-viscosity engine oils and management of oil pump as required, it is claimed that savings of up to 6 % are possible. We join Dr. Otmar Scharrer, Vice President of Corporate Research and Advanced Engineering, to discuss the remaining potential for minimising friction and how Mahle is successfully leveraging the same.
Dr.-Ing. Otmar Scharrer (1971) has been Vice President of Corporate Research and Advanced Engineering at Mahle in Stuttgart since 2016. He graduated in mechatronics engineering from the Johannes Kepler University Linz, and gained a doctorate degree from TU Berlin on the subject of variable valve gears in 2006. He began his career with the Voest Alpine Stahl Group in 1996. He subsequently worked for General Motors between 2001 and 2006. This was followed by two years at Porsche Engineering, where he oversaw simulation and engine testing, before working for Behr (now Mahle) in various management roles between 2009 and 2014. Scharrer was then Technical Director and Member of the Executive Board of AVL from 2014 prior to joining Mahle in 2016.
