“…PM 2.5 concentrations within the diesel exhausts of the 15 diesel vehicles ranged from 3875-16,458 µg m -3 , with the 1169-3881 µg L-fuel -1 emission factors accounting for the concentration average of 7927 µg m -3 and 2006 µg L-fuel -1 , as detailed in Table 2. It was further found that the concentration of PM 2.5 from the vehicle exhausts was affected by various factors, including vehicle type, fuel quality, vehicle model year, and the vehicle speed (Jhang et al, 2018;Lin et al, 2019). The results further showed that the diesel vehicle emissions had a significant effect on the PM 2.5 concentration.…”

“…The OC contribution was also observed to be declining in all pre-Euro to Euro 4 diesel vehicle groups, ranging from 2100 to 425 µg m -3 . Jhang et al (2018) found that the driving cycle, engine age, and engine technology are the major issues causing mass emissions of PM from diesel engines, which was similarly projected to have a substantial effect on the chemical composition of PM emissions from diesel engines. A study by Wei et al (2019) on ship emissions clearly validated that engine operating condition has a substantial effect on the fraction of EC to OC in the PM 2.5 emissions from dieselfueled vehicle working over an FTP cycle.…”

Urban air pollution in the form of fine particulate matter (PM 2.5) poses a substantial health threat to humans via inhalation. To assess the risks from this pollutant, we characterized and quantified the PM 2.5 exhausted by 15 diesel vehicles ranging from 28,306 to 883,374 km (an average of 525,854 km) in total mileage and varying in manufacturer and model year (1988-2005). We applied inductively coupled plasma optical emission spectroscopy (ICP-OES) to analyze the metallic element constituents, among which Ca composed the largest fraction, followed by Zn, Al, K, Fe, Mg, and Cr. Measuring the carbonaceous content, we found that the total carbon (TC), the organic carbon (OC), and the elemental carbon (EC) accounted for 3461 µg m-3 , 1410 µg m-3 , and 2051 µg m-3 of the PM 2.5 concentration, respectively. Of the metallic elements, Ca exhibited the highest emission factor (EF), between 45.3 and 259 µg L-fuel-1 (with an average of 132 µg L-fuel-1), whereas Zn and Cr displayed the lowest ones, averaging 13.1 µg L-fuel-1 and 1.91 µg L-fuel-1 , respectively. We also investigated the relationship between the concentrations and the EFs of the metallic elements in the exhaust, and the ambient PM 2.5 composition. These results help illustrate the contribution of PM 2.5 emitted by diesel vehicles to metallic element concentrations in the natural environment and the consequent risks.

“…Especially, hydrogen have been considered as sustainable options for diminishing petroleum-dependence and air pollutants emissions (Chang et al, 2017). Concerning on both limited fossil fuel and severe air pollution issues, hydrogen as an additive energy is able to improve engine efficiency and diminish the regulated and unregulated pollutant emissions (Chen et al, 2017;Jhang et al, 2018Jhang et al, , 2016. Hamdan et al (2015) has been stated that injecting small amount of hydrogen in diesel engine not only decreases the heterogeneity of diesel fuel spray but also reduces the combustion duration.…”

Pollution reduction related to combustion engines is considered to be an important issue around the world. Hydrogen as an additive energy has been utilized for alternative fuel since it need not require any modification. Particularly, it has been considered as a sustainable option for diminishing petroleum dependence and air pollutant emissions. In this study, we investigated the tailpipe emission with hydrogen addition for different driving behavior such as cold-start, idle, urban (UDC) and extra-urban (EUDC) under New European Driving Cycle (NEDC). The results showed that urban driving could attribute the most emissions in comparison to the high speed mode. Hydrogen addition enhanced the combustion process and the average reduction rates were observed 21.6% & 65.8% for hydrocarbon (HC), 2.37% & 85.4% for carbon monoxide (CO), and 7.53% & 59.3% for nitrogen oxides (NOx) when run at UDC and EUDC, respectively. The wide flammability of hydrogen ensures a homogeneous fuel-air mixture for complete combustion and reduces the HC, CO and NOx emissions. It is noteworthy that starting with less amount of hydrogen could greatly decrease HC followed by CO and NOx. Compared to conventional gasoline (G0), the average fuel consumption was reduced by 1.3% when a small amount of hydrogen was applied as an additive fuel.
