Method of verifying the emission level of the exhaust components of a special vehicle in relation to EURO III standard in road conditions

The following article presents the method of verification of EURO III standard in real conditions for special vehicles. The test object qualified as a special vehicle was tested in road conditions along a defined route, and then the obtained measurement results were compared to the exhaust emission standard (EURO III) applicable for this vehicle. A method of comparing the emission factors in road conditions with the indicators obtained on the engine dynamometer was proposed. An AVL mobile exhaust gas analyzers PEMS dedicated for RDE road tests were used in the research.
