چکیده
This study aimed to develop on-road NOx emission factors for Euro 6b light-duty diesel trucks (LDDTs) in Korea. On-road emissions were measured using portable measurement systems and compared with those the Korean Driving Cycle (KDC), conventional laboratory test used factors. To ensure representativeness of LDDTs factors, five vehicles three models driven along two real driving routes total traveled mileage 2280 km. levels 2.1 6.9 times higher on average than KDC because latter does not cover wide variability vehicle speed relative positive acceleration, common conditions. The lean-NOx trap was found have disappointingly low reduction efficiency driving. by speeds developed this comparable COPERT 4

On-road measurement of gas and particle phase pollutant emission factors for individual heavy-duty diesel trucks.
Pollutant concentrations in the exhaust plumes of individual diesel trucks were measured at high time resolution in a highway tunnel in Oakland, CA, during July 2010. Emission factors for individual trucks were calculated using a carbon balance method, in which pollutants measured in each exhaust plume were normalized to measured concentrations of carbon dioxide. Pollutants considered here incl...
متن کاملCharacteristics of Vehicle Emissions in China Based on Portable Emission Measurement System
Forty light-duty gasoline vehicles (LDGVs), ninety two diesel trucks (DTs), and twenty rural vehicles (RVs) were measured in Beijing, Xi’an, and Shenzhen in China using a portable emissions measurement system (PEMS). We obtained gaseous emission factors (EFs) for LDGVs of different emission control technologies (including Euro 0, Euro I, Euro II, Euro III and Euro IV), and EFs of fine particula...
متن کاملDriving patterns as a contributing factor to light-duty vehicular emission in the Kumasi metropolis
Exhaust emissions contribute greatly to air pollution, the social cost of which may occur as danger to human health, attracting huge medical expenses, causing absenteeism and hence loss of productivity. These are incentives to reduce exhaust emissions to the barest minimum. Two major cities in Ghana, Accra and Kumasi, are struck by vehicular traffic jams especially during rush-hours and are gra...

متن کاملTRB 08-1311 Link-Based Emission Factors for Heavy-Duty Diesel Trucks Based on Real-World Data
Heavy-duty diesel vehicles contribute a substantial fraction of nitrogen oxides and particulate matter to on-road vehicle emission inventory. The objectives of this study are to estimate roadway link-based emission rates for heavy-duty trucks for use in emission inventory estimation, and to quantify the impact of factors affecting truck emissions. A speed-acceleration modal emissions approach i...
