However, the understanding of the real-world emissions of diesel trucks is limited. In this study, we measured HC, CO, NOx, and PM2.5 emissions from 175 diesel trucks of different sizes and technologies in five Chinese cities during 2007 and 2011, and generated emission factors on the basis...
The Environmental Protection Agency has set strict emissions standards for heavy-duty trucks, buses and other large vehicles.
The American Trucking Associations and the Owner-Operator Independent Drivers Association, which represent large swaths of the industry, predicted supply chain failures and said that smaller independent firms would likely hang onto older diesel trucks that spew more pollution, running counter to the EPA'...
Long-term changes in emissions of nitrogen oxides and particulate matter from on-road gasoline and diesel vehicles Gas- and particle-phase pollutants were measured separately for (a) light-duty (LD) vehicles and (b) medium-duty (MD) and heavy-duty (HD) diesel trucks. Me... GA Ban-Weiss...
Electric trucks produce far fewer planet-warming emissions than their diesel counterparts over a lifetime, a report in Europe showed Tuesday, emphasizing that the biggest climate impact comes from driving vehicles and not ...
In-Use Activity, Fuel Use, and Emissions of Heavy Duty Diesel Roll-off Refuse Trucks The objectives of this study were to quantify real-world activity, fuel use, and emissions for heavy duty diesel roll-off refuse trucks; evaluate the contr... GS Sandhu,HC Frey,S Bartelt-Hunt,... - 《...
The trucks were found to perform adequately on neat F-T diesel fuel. Compared to a California diesel fuel baseline, neat F-T diesel fuel emitted about 12% lower oxides of nitrogen (NOx) and 24% lower particulate matter over a five-mile driving cycle. 展开 关键词:...
The paper reveals the state-of-the-art in exhaust emission behavior of diesel, gasoline and natural gas fueled vehicles. Passenger cars and light-duty trucks will be considered as well as HD-trucks. Emissions include NO{sub x}, THC, NMHC, CO, Aldehydes and PAH. In addition CH{sub 4} ...
Seventy-five diesel vehicles were measured in China using a portable emissions measurement system (PEMS). Particular matter (PM) emission factors and gaseous emission factors for Euro 0 (E0), Euro 1 (E1), Euro 2 (E2), and Euro 3 (E3) trucks were obtained under highway, urban, and rural...
For example, fuel-based NOX emission factors steadily decrease as the vehicle speed increases due to higher exhaust temperatures, which improve the efficiency of SCR systems. 展开 关键词: Heavy-duty diesel trucks NO_x emission PEMS SCR DOI: 10.4209/AAQR.2016.12.0531 被引量: 3 ...
