Measurement of rail vehicles exhaust emissions

Control of Exhaust Emissions from Internal Combustion Engined Vehicles

Exhaust emissions from light- and heavy-duty vehicles: chemical composition, impact of exhaust after treatment, and fuel parameters.

This paper presents results from the characterization of vehicle exhaust that were obtained primarily within the Swedish Urban Air Project, "Tätortsprojektet." Exhaust emissions from both gasoline- and diesel-fueled vehicles have been investigated with respect to regulated pollutants (carbon monoxide [CO], hydrocarbon [HC], nitrogen oxides [NOx], and particulate), unregulated pollutants, and in...

Non - exhaust traffic related emissions

Traffic related sources are a significant contributor of particulate matter, particularly in urban environments and major cities. Traffic related particles can be distinguished into: exhaust traffic related particles, which are emitted as a result of incomplete fuel combustion and lubricant volatilization during the combustion procedure, and nonexhaust traffic related particles, which are eithe...

Assessment for Fuel Consumption and Exhaust Emissions of China's Vehicles: Future Trends and Policy Implications

In the recent years, China's auto industry develops rapidly, thus bringing a series of burdens to society and environment. This paper uses Logistic model to simulate the future trend of China's vehicle population and finds that China's auto industry would come into high speed development time during 2020-2050. Moreover, this paper predicts vehicles' fuel consumption and exhaust emissions (CO, H...

Low-floor Light Rail Vehicles

his study explores the option of integrating a low-floor extension (LFE) module into the existing light rail vehicle to augment current service with low-floor boarding and simultaneously to increase passenger capacity. In an effort to minimize the overall weight of the LFE, this study examines two feasible approaches for specifying the longitudinal strength of the LFE that are consistent with c...
