- Pollutants emissions by on-road transport is still responsible for air pollution in urban areas
due to the growing number of circulating vehicle. Despite of technological improvements in
terms of engine and after treatment devices performance, exhausts of vehicles decisively
influence the urban air quality. In recent years particular concern is given to organic micropollutants
and particulate emissions, for their dangerous effects on humans and environmental
health. It was largely demonstrated the harmful aspect of particulate related to the its
dimensions and to its chemical composition. Smaller particles are able to penetrate more
deeply in human lungs and particles emitted ad the vehicle exhaust are mainly composed by a
carbonaceous fraction with condensed organics included carcinogenic substances such as
aromatics. Moreover, the European Commission wants to promote the purchase of fuelefficient
vehicles, as a strategy to reduce carbon dioxide emissions in the atmosphere which
represents a strong greenhouse gas. In order to characterize emissions and fuel consumption
of new available technologies, several tests were performed on a gasoline-electric hybrid car,
a bi-fuel vehicle fuelled with natural gas (CNG) and a diesel vehicle equipped with particulate
filter (DPF). All the vehicles, approved according to Euro 4 standards, were tested on chassisdynamometer
during type-approval and real driving cycles for computing emission factors of
carbon monoxide, hydrocarbons, nitrogen oxides, carbon dioxide and particulate
characterized as total number of particles and dimensional distribution. (literal)
