Additional information
care is needed when interpreting this figure. The NOx emissions limit for a Euro 2 diesel car is deduced as the limit was set for combined pollutants (HC + NOx) and the test procedure changed between Euro 2 and Euro 3. The trend of NOx emission factors is based on emission functions provided by COPERT 4 at speed 33.6 km/h.
