Continuous harmful gas exhaust component emission measurements at a frequency of 10 Hz over various drive cycles (NEDC, WLTC, FTP-75, HFET, US06, SC03, JC08, RDE simulation, or custom cycles).
Diluted exhaust measurement – 1 sampling point downstream of the vehicle.
Diluted exhaust concentration measurement: CO, CO2, NO, NOx, THC
Diluted exhaust emission calculations: CO, CO2, NO, NOx, THC
Undiluted exhaust measurement – any 2 sampling points, beginning with the engine exhaust manifold to a sampling point downstream of the vehicle.
Undiluted exhaust concentration measurement: CO, CO2, O2, NO, NOx, NO2, THC, CH4
Undiluted exhaust emission calculations: CO, CO2, O2, NO, NOx, NO2, THC, CH4
In the graph: Efficiency of the catalytic system (on the example of CO emissions) - based on the modal analysis of undiluted exhaust gas
