Impact of aftertreatment devices and driving conditions on unregulated emissions for Euro 5 vehicles

Résumé

Road traffic is a major contributor of air pollution in urban areas and particularly passenger cars. To reduce regulated emissions, new aftertreatment devices and new technologies were developed (catalysed or additived Diesel particle filter, direct injected gasoline vehicle...). These new technologies induce modifications of unregulated emissions (VOC, BTEX, PAH, NO2, black carbon, metals, ultrafine particles). Unregulated pollutants might induce many health effects regarding their toxicity and play an important role in air quality. Several VOC might act as precursor to form secondary organic particles by atmospheric photo-oxidation. Unfortunately, unregulated compound emissions are not controlled and very few data are thus available because of the small number of recent tested vehicles. This work aims to improve the knowledge on unregulated compound emissions from recent Euro 5 vehicles. Impacts of aftertreatment technologies together with diverse driving conditions (urban cold/hot start, rural and motorway) were studied. The particle filter regeneration has also been investigated.
