Particulate emissions from biodiesel fuelled CI engines

Regional Similarities and NOx‐Related Increases in Biogenic Secondary Organic Aerosol in Summertime Southeastern United States

“…The FFC factor time series was correlated more strongly to Ca, Mn, and Fe concentrations ( r = 0.3 to 0.6) than the other FTIR factors ( r = −0.4 to 0.3) at both sites. These metals were found in combustion sources and have served as combustion tracers in previous studies (Agarwal et al, ; Cheung et al, ; Verma et al, ). The FFC factors at the two sites peaked in the late afternoon (1600–1900, 40% higher than the rest of the day), indicating a photochemical contribution to the OM as seen from 8 to 9 June at both sites (Figure S3).…”

Improving exergetic and sustainability parameters of a DI diesel engine using polymer waste dissolved in biodiesel as a novel diesel additive

“…Biodiesel (methyl or ethyl esters of long chain fatty acids), possesses characteristics similar to those of diesel while the biggest difference is its oxygen content leading to a more complete combustion and consequently less generation of pollutants [6,7]. A significant amount of literature exists on performance, combustion, and emission characteristics of diesel engine fuelled with various diesel/biodiesel blends [8][9][10][11][12][13][14][15][16], and it is well-documented that the overall energy obtained through biodiesel combustion is lower than that of mineral diesel fuel [6]. In our previous studies, in order to compensate for this drawback, expanded polystyrene (EPS) wastes were used in biodiesel to benefit their energy content when recycled into the fuel blend [3,[17][18][19].…”

Development of low cost mixed metal oxide based diesel oxidation catalysts and their comparative performance evaluation

“…25,44 In present study, EC/OC emissions were evaluated to determine; (1) effect of biodiesel; and (2) effect of DOCs. One important point to be noted constituents of particulate.…”

“…These issues encourage development of non-noble metal based catalysts for DOCs, which could prove to be a promising, long-term and sustainable solution for aer-treatment devices. Experimental studies 25,26 have shown that biodiesel emits lower PM emissions compared to baseline diesel due to its inherent oxygen content. Grisel 23 Liang et al investigated catalytic activity of Cu/Mn doped ceria for diesel soot oxidation and reported that Cu-Ce interaction signicantly enhanced release of lattice oxygen from the oxides.…”

“…Few scientic studies [11][12][13][14][15][16][17][18][19][20][21][22] investigated effectiveness of non-noble metal based catalysts for reduction of diesel emissions. 25,[27][28][29] In present study, an attempt has been made to prepare and evaluate two non-noble metal based DOCs for diesel engine emission reduction in combination with Karanja biodiesel blend (B20). Both catalysts showed superior catalytic behavior and selectivity to CO 2 for soot oxidation, compared to ceria.…”
