“…For all fuels, the smoke emission ascends with BMEP, due to augmentation in consumption, which leads to a rich mixture. The graph clearly indicated that smoke emission for all CFME blends is inferior to PD due to intrinsic oxygen present in CFME structure, because of which the mean size of fuel spray droplet remains small which causes boost A/F mixing process, resulting in lean fuel zone inside combustion chamber (increase soot oxidation), thus lesser smoke formation [49]. At maximum BMEP, 1.51%, 5.39%, and 11.65% smoke reductions are found for B10, B20, and B30 blends respectively compared to PD.…”

In recent years, industries have been investing to develop a potential alternative fuel to substitute the depleting fossil fuels which emit noxious emissions. Present work investigated the effect of ferrous ferric oxide nano-additive on performance and emission parameters of compression ignition engine fuelled with chicken fat methyl ester blends. The nano-additive was included with various methyl ester blends at different ppm of 50, 100, and 150 through the ultrasonication process. Probe sonicator was utilized for nano-fuel preparation to inhibit the formation of agglomeration of nanoparticles in base fuel. Experimental results revealed that the addition of 100 ppm dosage of ferrous ferric oxide nanoparticles in blends significantly improves the combustion performance and substantially decrease the pernicious emissions of the engine. It is also found from an experimental results analysis that brake thermal efficiency (BTE) improved by 4.84%, a reduction in brake specific fuel consumption (BSFC) by 10.44%, brake specific energy consumption (BSEC) by 9.44%, exhaust gas temperature (EGT) by 19.47%, carbon monoxides (CO) by 53.22%, unburned hydrocarbon (UHC) by 21.73%, nitrogen oxides (NOx) by 15.39%, and smoke by 14.73% for the nano-fuel B20FFO100 blend. By seeing of analysis, it is concluded that the doping of ferrous ferric oxide nano-additive in chicken fat methyl ester blends shows an overall development in engine characteristics.

“…Other challenges that cannot be ignored when using biofuels would come from the effects of properties such as viscosity, density, and vaporization on engine stability and durability (Hoang, 2019) (Tham et al, 2019) (Gupta and Agarwal, 2021). Therefore, phenomena such as spray characteristics (Hoang, 2018), combustion chamber deposit formation (Le et al, 2019) (Reddy and Nanthagopal, 2021) (Anh and Anh, 2019), or lubricant degradation (Ashok et al, 2020) (Pham and Hoang, 2019) when using furan-based fuels in the future need to be further considered. In addition, the problem of corrosion of parts in the fuel system and combustion chamber also needs to be thoroughly investigated when using DMF fuel for internal combustion engines .…”

Since the early years of the 21st century, the whole world has faced two very urgent problems: the depletion of fossil energy sources and climate change due to environmental pollution. Among the solutions sought, 2,5-Dimethylfuran (DMF) emerged as a promising solution. DMF is a 2nd generation biofuel capable of mass production from biomass. There have been many studies confirming that DMF is a potential alternative fuel for traditional fuels (gasoline and diesel) in internal combustion engines, contributing to solving the problem of energy security and environmental pollution. However, in order to apply DMF in practice, more comprehensive studies are needed. Not out of the above trend, this paper analyzes and discusses in detail the characteristics of DMF's combustible laminar flame and its instability under different initial conditions. The evaluation results show that the flame characteristics of DMF are similar to those of gasoline, although the burning rate of DMF is much higher than that of gasoline. This shows that DMF can become a potential alternative fuel in internal combustion engines.

“…Higher oxygen content in the fuel and complete combustion results in greater emission of CO 2 which is inversely proportional to the emission of CO (Ashok et al 2020;Soudagar et al 2021) . the variation of CO 2 with respect to the load for different test fuels are as shown in g.15.…”

In present scenario, the fast depletion of fossil fuels and energy crises motivated the researchers towards finding an alternative sources for energy. In this work, the performance, combustion and emission of hydrothermally synthesized ZnO nanoparticles dispersed waste cooking oil biodiesel in single cylinder, four stroke, Direct Injection- Diesel Engine with eddy current dynamometer was investigated. The synthesized ZnO nano particles were characterized by XRD, FTIR, SEM and EDX to find crystallinity, functional groups and surface morphology. Waste cooking oil biodiesel was produced via conventional one step alkali catalyst Trans-esterification process. Test fuels were prepared with dispersion of ZnO nanoparticles in the concentration of 10ppm, 20ppm and 30ppm with B20 (20% waste cooking oil biodiesel and 80% diesel) with the aid of magnetic stirrer and ultra-sonication. The test results exposed that the addition of ZnO nanoparticles with B20 gave better Performance in terms of BTE and BSFC compared to B20. The addition of ZnO nano particles with 30ppm concentration was identified as better fuel among all tested fuels in this work. 30ppm addition of ZnO nano particles with B20 records 1.78 % increase in BTE and 10.34% decrease in BSFC. The emission like CO, HC and smoke were 20%, 15.4% and 17.39% lower than diesel. On the other hand NOx was slightly higher than diesel but lower than B20.
