The Coburg’s fuel research system includes a 2019 4-wheel drive chassis dynamometer for emission testing of conventional, hybrid and battery electric vehicles. This test bench allows for reproducible vehicle tests at modern emission test-cycle conditions sich as WLTP, RTS95, JC08, FTP75 or even NEDC. Moreover, the test-bench is prepared for signal synchronization between test-bench and vehicle instrumentation data for detailed processing of fuel dependent operation conditions.
