Real-world gaseous and particulate emissions from Euro IV to VI medium duty diesel trucks

Alternative Exhaust Emission Factors from Vehicles in On-Road Driving Tests

“…Based on the results obtained and presented in the article and on the results of other researchers [1,[4][5][6][7], as well as previous co-authored publications on the measurements of emissions of exhaust compounds using PEMS [17][18][19][20][21][22][23], the authors undertook to formulate an indicator that would merge all the results obtained. Such an indicator would characterise the vehicle environmentally in terms of only harmful substances of exhaust emissions NO x , PN, and CO 2 (since only such a scope of works was ultimately considered as the principal scope in this article).…”

“…At the same time, the results suggest that attention should be paid to carbon monoxide and particle number emissions from certain types of vehicles under dynamic conditions. Papadopoulos et al [6] report emission factors for the design of medium-duty diesel trucks equipped with diesel particulate filters (DPFs), for which tests were conducted under real driving conditions. Gaseous and particulate emissions and fuel consumption of 14 trucks with Euro IV, Euro V, and Euro VI diesel engines were analyzed, evaluating the effectiveness of various emission control technologies used.…”

Vehicular PM Emissions and Urban Public Health Sustainability: A Probabilistic Analysis for Dhaka City

“…Therefore, the contribution of the traffic system to urban air quality and public health is subjected to all the emissions. However, considering severe PM pollution in Dhaka City, and for the significant contribution of that from vehicles [45][46][47][48][49][50][51][52][53][54][55][56], this research intended to individually assess the PM pollution risks correlated to the consistent vehicular sources only, aiming to analyse the city's sustainability when other sources are maintained. This study will also aim to assess whether sustainability would be compromised if the current trend continues, and if planning and policies are not incorporated into the management approach strictly.…”

“…However, these reductions are not solely from reduced vehicular emissions, somewhat reduced industrial emissions also had a part. Again, concerning the PM emissions from vehicles, research indicates that improved vehicle technology and higher speed might reduce PM emissions by 50% [47,52,72], considering other factors being involved in such reductions. Therefore, a modelling study that considers such factors can be useful to predict the contribution of vehicular emissions and what extent that needs to be managed.…”

“…To reduce the uncertainty of these parameters induced from limited surveys, implementing Monte Carlo simulation technique [80,81] Emissions of different pollutants are attributed to various processes. Likewise, PM emissions from vehicle exhaust depend mainly on the fuels (gasoline and diesel mostly) [47,51,56,[72][73][74] and engine technology [47,52,64,75], primarily when an engine is operated in a low-temperature condition [8,35]. Although the particulate matter is categorized in PM 2.5 or PM 10 , however, this research considers the emission of PM 2.5 , as the coarse fraction, present in an insignificant amount in vehicle exhausts [64].…”
