Abstract Variable Compression Systems for Internal Combustion Engines will become increasingly more important to meet stringent global fuel economy standards. A 2-Step VCS system is in development in cooperation of AVL and IWIS and the basic functionality was described in a technical paper, presented at the JSAE 20175333. The system is based on a hydraulically switched and locked conrod with telescopic shank. This paper discusses the main development results which have been obtained for the Proof of Concept and for the completion of the functional and design validation as well as the industrialisation concept with a modular production approach.
