Tailpipe emissions of Euro 5 mopeds
report
The ubiquitous Euro 2 mopeds have been the primary subject of TNO’s emissions
measurement studies in the past. In general, the pollutant emissions of the previously
tested Euro 2 and Euro 3 mopeds substantially exceed the emissions of modern petrol
passenger cars. Currently, the share of Euro 4 and Euro 5 mopeds on the Dutch market
are growing (Euro 3 was hardly sold in the Netherlands). It is necessary to understand
the emission performance of these modern mopeds and to compare them to the
well-documented Euro 2 mopeds. The aim of this research was to determine emission performance of Euro 5 mopeds with a variety of characteristics. The impact of cold start emissions on emissions was investigated as well. This research was carried out on behalf of the Dutch Ministry of Infrastructure and Water Management. Four in-use Euro 5 mopeds were selected for the testing program. The selected mopeds are representative for the Dutch moped fleet. The moped characteristics varied in maximum vehicle speed (25 and 45 km/h), mileage, price range, brand and type. The tests were performed with in-use mopeds, with a mileage between 350 and 6.000 km. The mopeds were all subjected to two tests on a chassis dynamometer. Including the legislative test cycle (WMTC) for Euro 5 mopeds, and the former legislative test cycle (ECE-R47).
