“…Figure 11 shows the oxides of nitrogen (NOx) emission of different fuel samples tested at different load conditions. In general, the formation of NOx is affected by the peak fl ame temperature, the high burning gas temperature, the ignition delay and the content of nitrogen and oxygen available in the reaction mixture (Imdadul et al 2017).…”

Biofuel based energy is likely to be promoted to reduce the dependency on fossil fuels. The most common alternative fuel is FAME biodiesel that is produced by trans esterifi cation. But some disadvantages are also associated with biodiesel; new technologies are under investigation for the production of other biofuels. In the present study green diesel was produced by hydro processing of waste cooking oil. The performance and emission characteristics of green diesel were investigated in single cylinder CI engine. The results were also compared by the corresponding results obtained by conventional diesel fuel. The engine was tested in a series of steady state operating conditions at different load by keeping constant speeds of 1500 rev/min. The performance parameters like brake thermal effi ciency (BTE %), specifi c fuel consumption (SFC in kg/h) and emissions parameters like HC, CO 2 , CO and NOX emissions were investigated. It was observed that BTHE of green diesel is 23% and 21.76% for petro diesel at 20% load, at 40% load it is 34.24% for green diesel and 25.8% for petrol diesel at 60% load it is 35.93% for green diesel and 31.74 for petro diesel at 80% load it is 38.24 for green diesel and 31.66 % for petro diesel at 100% load it is 31.6% for both green diesel and petro diesel These results show that BTHE increases for green diesel fuels at all load except full load condition. From the results, it was found that for green diesel BSFC(kg/kwh) is1.83 for green diesel and 2.57 for petro diesel at no load condition and at full load it is 0.267for green diesel and 0.270 for petro diesel which is less as compare to petro diesel. It was observed that CO (%VOL) at load (%) 20,40,60,80,100 for green diesel are 0.06, 0.03,0.02,0.02,0.03 and for petro diesel are 0.06,0.04,0.03,0.03 and 0.04 respectively. It is observed that HC (PPM) emission at load (%

“…As expressed before, flash point will be estimated using these two properties. Therefore, in this section the focus will be on an exhaustive review of flash point experimental data of biodiesel/diesel blends from edible [25-27, 30, 38-67] and non-edible oils [9,25,49,50,52,53,[59][60][61][62][68][69][70][71][72][73][74][75][76][77][78][79][80][81][82][83][84][85].…”

This paper presents characterization studies of flash point, kinematic viscosity and refractive index for several biodiesel/ diesel blends. Biodiesel is produced from soybean, corn, olive, canola, almond, grape and peanut oils. Regression equations are presented to estimate the kinematic viscosity, refractive index and flash point of the studied biodiesel and their blends with diesel fossil fuel as a function of the blend composition. Moreover, as viscosity and refractive index measurements are simple, fast and require very small volume of samples, a correlation study for the blends is conducted to estimate the flash point from these two properties. It is shown that when kinematic viscosity and refractive index are both used for the estimation of the blends flash point, the R 2 values are higher than those found using simple correlations.

“…According to Imdadul et al (2016cImdadul et al ( , 2017, although CN improvers such as EHN and di-tertiary-butyl peroxide when added with pentanol-treated palm oil biodiesel blends at a proportion of 1,000 and 2,000 ppm have the potential of decreasing NO and smoke emissions compared with biodiesel and ternary alcohol blends, the level of NO emission was still higher than that in diesel. In addition, CO and HC increased slightly with cetane improver, but not more than those of diesel.…”

Of several higher alcohols such as pentanol, hexanol, octanol, decanol, dodecanol, phytol, and fusel oil, pentanol isomers have recently received remarkable attention as alternative fuels for diesel engines because they emit less greenhouse gases and harmful pollutants. Because of great potential as a blending component and physicochemical properties of pentanol, binary blends such as diesel/pentanol and biodiesel/pentanol and ternary blends such as diesel/biodiesel/pentanol were mainly studied in the conventional diesel engine. Quaternary blends of diesel, biodiesel, straight vegetable oil, and pentanol were also investigated. Very few information related to the application of pentanol to advanced compression ignition (CI) engine is available in the literature. The diesel/pentanol blends coupled with exhaust gas recirculation (EGR) technology could simultaneously reduce NOx and soot emissions from CI engine. Further, diesel/pentanol blends generally produced higher CO and hydrocarbon (HC) emissions than did diesel fuel. However, CO and HC emissions were significantly reduced by mixing the cetane improver with the blends. Up to 45-50% n-pentanol/diesel blends can be safely used in diesel engines without any engine modification or any additive. However, in terms of kinematic viscosity, lubricity, and oxidation stability of diesel/pentanol blends, the use of pentanol should be limited to concentrations below 10%. Generally, in the studies of biodiesel/pentanol blends in CI engines, the reduction of CO, HC, NOx, and smoke emissions was observed compared to neat biodiesel. For ternary blends, diesel/biodiesel/pentanol blends were mainly investigated by the researchers. The emission characteristics in terms of CO, HC, NOx, and smoke opacity showed the different trends according to the pentanol proportion in the ternary blends, particularly <10% or more than 10%. To increase the biofuels in the CI engine, more studies for the quaternary blends of pentanol are required.
