Research output: Contribution to journalArticleAcademicpeer-review


Two new technologies, the „floating cup"-principle and a new hydraulic transformer, allow the complete substitution of the mechanical drive of a passenger car for a series hydraulic hybrid transmission. The new "Hydrid" power train from Innas and the RWTH Aachen University reduces the fuel consumption of a medium-sized car by 50 %. The CO2 emissions are reduced to 82 g/km, a level far below the EU-limit for the year 2012 (120 g/km).
