Emission measurement system for testing a combustion engine including exhaust gas exposure of biological cells

An emission measurement system 100 for testing a combustion engine 11, in particular of a vehicle 10, comprises a sampling device 20 for collecting exhaust gas 12 created by the combustion engine 11 and a testing device 30 being coupled with the sampling device 20 and being configured for applying at least one test to a test sample 13 including the exhaust gas 12, wherein the testing device 30 includes a cell exposure device 31 being configured for accommodating at least one sample 1 of biological cells 2 and exposing the biological cells 2 to the test sample 13 and an analysing device 33 being configured for testing the biological cells 2. The emission measurement system 100 comprises e. g. a car test bench or portable test apparatus. Furthermore, methods of testing a combustion engine 11, in particular of a vehicle 10, are described.
