Nowa procedura przeprowadzania badań emisji spalin z pojazdów samochodowych z wykorzystaniem testów drogowych

Until now, passenger cars before getting permission to sell were tested in the laboratory conditions in order to determine the amount of harmful gas compounds emission and average fuel consumption. However, studies have shown that, during real driving, emission results significantly differ from those obtained in the laboratory. For this purpose, the European Commission has created a new procedure for conducting of driving cycle WLTP (World Harmonized Light-Duty Procedure) taking into account road test (Real-Driving Emissions, RDE). The article presents selected results of pollutant emissions research using the HORIBA OBS 2200 road analysis system.
