“…However, decrease in smoke with all nano-additive blends is mainly due to the existence of oxygen molecules in the functional group of FFO nanoparticles which released to the combustion zone during the premixed combustion phase. The abruptly availability of oxygen enhanced the burning rate of fuel which leads to reduced ignition delay, resulting in more fuel burnt during diffusion stage and increase the oxidation of soot particles, hence lower smoke formation [34]. Similar observations for three different nano-additives are noticed by Gad and Jayaraj [17].…”

“…From CO emission investigational results, CO emission dropped for all nano-additive fuels as the quantity of FFO nanoparticles in fuel increased up to 100 ppm. For higher quantity (150 ppm), it increased slightly, attributed to the rise in agglomeration rate of nanoparticles which leads to a diminution in overall surface area for catalytic activity [34]. A similar observation for CO emission was reported by Khan et al [35].…”

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.

“…Nivin Chacko et al [14] have studied a diesel engine fueled with waste-cooking biodieseldiesel blends and reported lower PM, while slightly increased NOx. Inference concludes that some studies have been conducted to evaluate the utilization of biodiesel derived from fruit seeds in diesel engines [15][16][17][18][19][20][21][22][23][24]. However, no reported studies focus on engine performance and exhaust emissions employing biodiesel derived from the custard seeds oil.…”

In this study, the nano biochar derived from sugarcane was added with custard seed biodiesel (CBD) at different concentrations of 25 and 50 ppm to assist the emission and performance pattern of a compression ignition engine. The study monitored harmful gases, namely, hydrocarbon (HC), carbon monoxide (CO), nitrogen oxide (NO), and smoke as emission parameters and investigated brake specific fuel consumption (BSFC) and brake thermal efficiency (BTE) as performance parameters are analyzed at diverse loads by altering the concentration the biochar with CBD and compared with diesel. Experimental results revealed that the biochar addition at 50 ppm to CBD reduced smoke emission by 1.9%, CO by 0.005%, and HC by 6 ppm at all top load conditions with 71 ppm higher NO. Further, biochar addition at 50 ppm to CBD enhances the brake thermal efficiency by 0.7% and lower brake specific fuel consumption by 0.4 kg/kWh.

“…Additives are chemical substances that are introduced with Fuel as a means of adjusting the fuel properties. (Chacko and Jeyaseelan 2020;Tomar and Kumar 2020) Various fuel additives, including antioxidants, oxygenates, metal and metal oxides, cetane enhancers, lubricants and cold ow enhancers, have been widely used as fuel additives (Hosseinzadeh-Bandbafha et al 2018). The addition of a fuel additive from 20 ppm to 500 ppm is at an affordable level.…”

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.
