Summary:

In all the world mopeds and motorcycles are popular means ofdaily moving, helping to meet daily urban transport needs, as aconsequence two-wheelers contribution to air pollution is generallysignificant, especially in urban environment. Emission modelscommonly used in Europe, are based mainly on the average trip speedto predict emissions, thus they are not sensitive to variations ofvehicles instantaneous speed and acceleration, which have a strongeffect on emissions and fuel consumption; besides these models donot analyze in depth the cold emissive behavior of motorcycles. Anexpansion of the two-wheelers emission database was deemednecessary.This study is aimed at the examination of the emissions ofin-use motorcycles during real driving conditions, contributingsignificantly to extend the knowledge of two-wheeler emissionbehavior. For this purpose, an experimental investigation wasrealized by the Department of Mechanic and Energetic (DiME) of theUniversity of Naples: emissions of regulated pollutants (CO, HC andNOX) were evaluated in the exhaust of one scooter belonging tothe Euro-3 legislative category, equipped with catalytic converter,and with a displacement of 300 cm₃. In order to evaluate theperformance of this motorcycle under real-world motorcycle riding,in cold and hot conditions, sampling was achieved on a dynamometerbench during both the Type Approval driving cycle and real-worlddriving cycles, also by employing the instantaneous emissionresults. The experimental data and the statistical processingresults of this research are compared with current emission modelsfor calculating emissions from road traffic
