“…Low-temperature combustion has its unique advantage to reduce NO x [27]. The lowtemperature combustion mode of bio-diesels has also been reported recently [28][29][30][31][32][33][34][35]. Advanced injection strategy was used to implement better emissions of bio-diesel for HSDI diesel engines [28,34].…”

“…Simultaneous reduction of NO x and soot emission was achieved for bio-diesel-diesel blend with high-efficiency clean combustion (HECC) in a diesel engine [29]. Zheng et al [30] investigated low-temperature combustion mode for bio-diesel with high EGR rate. The results showed that it was possible to achieve NO x and soot reductions for low-temperature combustion modes with biodiesel.…”

“…While the CO and HC emissions are high in SI engines, PM and NO x emissions are higher in CI engine [3,4]. Even so diesel engines produce higher PM and NO x they are prefered owing to lower fuel consumption and having higher thermal efficiency [8][9][10][11][12][13]. Thus, many researchers have tried to develop the properties of the diesel fuel.…”

In this study, the effects of hazelnut oil–diesel (H30), corn oil–diesel (C30), soybean oil–diesel (S30), sunflower oil–diesel (Su30), canola oil–diesel (Ca30) and Crambe abyssinica oil–diesel (Cr30) and diesel fuel blends were investigated on combustion characteristics, engine performance and NOx, CO, HC, and soot emissions. A single cylinder, four stroke, direct injection diesel engine was operated at maximum brake torque engine speed of 2200 rpm and 7.5, 11.25, 15, and 18.75 Nm engine loads. Test results showed that thermal efficiency decreased by about 3.1, 6.44, 7.08, 7.40, 8.76, and 11.68% with H30, C30, S30, Su30, Ca30, and Cr30 compared to D100 at full load, respectively. There was no big differences on cylinder pressure between test fuels. However, higher heat release rate was obtained with D100 according to fuel blends due to higher calorific value of D100. Test results also showed that HC, CO, and soot emissions decreased with biodiesel fuel blends compared to diesel fuel for all engine loads while NOx emissions increased. At full load, HC and CO decreased by about 81.2 and 21.5%, respectively, with C30 compared to diesel. Similarly, soot reduced 51.3% with Su30 compared to diesel at the same engine load. However, NOx increased 15.8% with C30 according to diesel at full load. It was concluded that biodiesel–diesel fuel blends can be used efficiently in a diesel engine. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 1438–1447, 2018

“…These biodiesel characteristics result in changes in combustion behavior with respect to petroleum-based diesel fuel. Shorter ignition delay [1][2][3][4][5], greater penetration length [2,6,7], and less premixed-bum fraction [1,3,4,8] are well-documented characteristics of biodiesel blends. However, in-cylinder spray and mixing of biodiesel blends have been experimentally explored to a lesser extent, and research on the effect of biodiesel content on these processes is inconclusive.…”

Biodiesel is a desirable alternative fuel for the diesel engine due to its low engine-out soot emission tendency. When blended with petroleum-based diesel fuels, soot emissions generally decrease in proportion to the volume fraction of biodiesel in the mixture. While comparisons of engine-out soot measurements between biodiesel blends and petroleumbased diesel have been widely reported, in-cylinder soot evolution has not been experimentally explored to the same extent. To elucidate the soot emission reduction mechanism of biodiesel, a single-cylinder optically-accessible diesel engine was used to compare the in-cylinder soot evolution when fueled with ultra-low sulfur diesel (ULSD) to that using a B20 biodiesel blend (20% vol.lvol. biodiesel ASTM D6751-03A). Soot temperature and KL factors are simultaneously determined using a novel two-color optical thermometry technique implemented with a high-speed CMOS color camera having wide-band Bayer filters. The crank-angle resolved data allows quantitative comparison of the rate of in-cylinder soot formation. High-speed spray images show that B20 has more splashing during spray wall impingement than ULSD, distributing rebounding fuel droplets over a thicker annular ring interior to the piston bowl periphery. The subsequent soot luminescence is observed by high-speed combustion imaging and soot temperature and KL factor measurements. B20 forms soot both at low KL magnitudes over large areas between fuel jets, and at high values among remnants of the fuel spray, along its axis and away from the bowl edge. In contrast, ULSD soot luminescence is observed exclusively as pool burning on the piston bowl surfaces resulting from spray wall impingement. The soot KL factor evolution during B20 combustion indicates earlier and significantly greater soot formation than with ULSD. B20 combustion is also observed to have a greater soot oxidation rate, which results in lower late-cycle soot emissions. For both fuels, higher fuel injection pressure led to lower late-cycle soot KL levels. The apparent rate of heat release (ARHR) analysis under steady skip-fire conditions indicates that B20 combustion is less sensitive to wall temperature than that observed with ULSD due to a lesser degree of pool burning. B20 was found to have both a shorter ignition delay and shorter combustion duration than ULSD.
