LITERATURE REVIEW ON STABILIZING HIGH SPEED VALVE- AND DRIVETRAIN CONCEPTS FOR RACING APPLICATIONS Internship at the engine development department of Audi Sport Prof. Dr. Ir. A. de Boer Dipl. -Ing. S. Wohlgemuth Thomas Roodink s1501623
[email protected] Introductory remarks In the summer season of 2016 I was allowed to do a six month internship within the research department of Audi Sport in Neckarsulm Germany. A dream came true after Le Mans 2015 when I offered my curriculum vitae to Mr. Baretzky, head of the engine department of Audi Sport. I want to thank him deeply for giving me the opportunity to be part of his team. Moreover, I want to thank Prof. Dr. Ir. A. de Boer of the University of Twente for the great support during the internship and for his flexibility before the start of the internship. A very special thanks goes to Dipl. -Ing. S. Wohlgemuth of the engine research department of Audi Sport for sharing his great knowledge, passion and support. “There is no such thing as cam design, there is only valve lift profile design which requires the creation of a cam and follower mechanism to reliably provide this designed valve lift profile.” G.
