CDV research examined polycyclic aromatic hydrocarbon emissions from passenger cars in urban, suburban and highway driving and compared the effects of driving mode and emission standard.
Summary
This article deals with the influence of driving mode on polycyclic aromatic hydrocarbon (PAH) emissions from passenger car exhaust gases in real traffic conditions.Measurements weretakenonvehiclesofvariousemissioncategoriesandenginetypes,withsamplingcarriedouton a route covering urban, suburban, and highway driving. Particular attention was given to PAHs bound to solid particles, whose concentrations were analyzed in relation to driving dynamics in different driving modes. The results show significant differences in emission profiles depending on the driving mode and emission standard, which has important implications for assessing the environmental impact of transport and designing effective measures to reduce pollutant emissions from real-world driving.
