“…Mean while, Selvan et al [5] added cerium oxide nanoparticle of 25 ppm in diesel-biodiesel-ethanol blends and found improved brake specific fuel consumption with reduction of Unburned HC, CO, NO and Smoke opacity. Basha and Anand [6] blended Carbon Nanotube at 25, 50 and 100 ppm in Jatropha methyl ester emulsion (5% of water and 2% of surfactants (by volume)) and found drastic percentage reduction of NO by 29 % and smoke opacity by 28 % in a single cylinder, four-stroke, direct injection diesel engine. The same team [7] carried out experimental investigation with alumina nanoparticle, blended at 25 and 50 ppm in biodiesel emulsion fuel and observed drastic percentage reduction of NO by 27 %, smoke opacity by 40 % with marginal reduction of HC and CO emission.…”

IntroductionThere is an increasing demand to find out the biodegradable and environmental friendly fuel to meet the future energy demands. Several legislations were followed for improving the disadvantage of biodiesel fuel such as increased NOx emission and soot particles. To achieve standard emission norms, many studies have been conducted over past few decades. Among them, recent fuel additives namely antioxidants and nanoparticles were preferred for minimizing the NOx emission effectively. Fattah et al., [1] used antioxidants namely monophenolic, 2(3)-tert-Butyl-4-methoxyphenol, 2,6-di-tert-butyl-4-methylphenol, diphenolic, 2-tert-butylbenzene-1,4-diol as additive in calophyllum inophyllum biodiesel blends at 2000 ppm (parts per million) and observed percentage reduction of NOx emission by 3.6 % and improvement in brake specific fuel consumption by 1.5 % along with higher emission of carbon monoxide (CO) and unburned hydrocarbon (HC) in a four cylinder, four stroke, water cooled, indirect injection diesel engine. Varatharajan et al., [2] conducted experimental investigation in computerized four stroke water cooled single cylinder diesel engine by adding antioxidant additives, N,N′-diphenyl-1,4-phenylenediamine and N-phenyl-1,4-phenylenediamine at 1000 and 2000 ppm with soybean biodiesel and observed 14 % increase in CO, 16 % increase in HC emission, 9 % reduction in Nitric oxide (NO) and 0.8 % reduction in brake thermal efficiency (BTE). Similarly, when N, N-diphenyl-1,4-phenylenediamine at 150 ppm was blended with jatropha diesel blends, 16 % reduction in NO was observed with higher emission of HC and CO [3]. From the antioxidant studies, it is observed that antioxidants as additive in fuel was effective for NO reduction, whereas the brake specific consumption, HC and CO emission increases for antioxidant addition. In contrast, when nanoparticles were used as additive in fuel, significant improvement in both performance and emission characteristics were observed.Sajith et al. [4] experimented with cerium oxide nanoparticle at 20, 40 and 60 ppm addition in jatropha biodiesel and observed significant reduction of NOx by 30 % and HC by 40 % in a fourstroke, single cylinder, water-cooled compression ignition. They observed that the significant reduction of NOx and HC emission

“…The enhancement in brake thermal efficiency for the modified fuel at 220 bar injection pressure and 23° bTDC has reflected lower brake specific fuel consumption when compared to that of diesel and 20MEME‐80D fuel as shown in Figure . It was observed experimentally that, as the load increases the brake thermal efficiency decreases for all the test fuels among which 20MEME‐80D and diesel resulted in higher BSFC compared with other fuels, due to its higher viscosity.…”

Nowadays, rapid increase in vehicle population led to increase in demand of fossil fuel. Decrease in availability of crude oil made the researchers to find a renewable alternative fuel, biofuels. Methyl esters are preferred as alternative to petro‐diesel engines. The present experimental study of Mimusops elangi methyl ester (MEME) is used as biodiesel on single cylinder four stroke, direct injection air cooled diesel engine at a constant speed of 1500 rpm at various loads. The general optimum biodiesel blends 20MEME‐80D (20%MEME‐80%Diesel) with optimum of 25 ppm TiO2 nanoparticle additives were taken for the experiment. The injection pressure of the engine is varied from 180 bar to 240 bar in the steps of 20 bar. The results of experimental investigation reported that the change in injection pressure 220 bar with modified fuel (20MEME‐80D + 25 ppm TiO2 nanoparticle) shows better performance and emission characteristics in the diesel engine. © 2019 American Institute of Chemical Engineers Environ Prog, 38:e13146, 2019

“…The mixing of carbon nanotubes with Jatropha biodiesel resulted in a drop in maximum cylinder pressure and heat release rate. Carbon‐based nanoparticles act as a catalyst during the combustion process, which thus decreases the ignition delay effect . Higher viscosity and lower calorific value associated with neem biodiesel result in lower evaporation rate, hence limiting its use in combustion applications.…”

“…The doping of nanoadditives in neat biodiesel reduces the exhaust emissions and also improve the performance parameters . Basha and Anand in their experimental study showed that an enhancement in evaporation rate and reduction in ignition delay was observed when carbon‐based nanoparticles (CNT) were blended with neat diesel fuel. Colwell and Reza proposed a correlation between hot plate temperature and ignition expectancy.…”

Summary Biodiesel obtained from inedible sources emerged as a productive approach in Indian energy scenario due to the scarcity of food resources come up with extensive usage of edible crops. Kusum (Schleichera oleosa) oil is abundantly available in India and can be used as feedstock to produce biodiesel. However, issues such as higher viscosity, poor stability, and lower calorific value result in poor ignition characteristics, hence limiting its use in combustion applications. An improvement in performance and emission characteristics can be achieved by doping nanoparticles in Kusum biodiesel (KBD). The present work examines the impact of a metal compound and carbon‐primarily based nanoparticles on the evaporation time and ignition probability of the KBD. During the experimental process, different fuel samples of KBD were prepared by amalgamating nanoparticles; then, a sequence of hot plate (stainless steel) ignition test was conducted on these test fuels. The comparative assessment of neat biodiesel and the biodiesel fuel doped with 30 ppm each of alumina (Al2O3), and multiwalled carbon nanotubes (MWCNTs) nanoparticles were carried out. The Kusum oil was converted to biodiesel using two‐stage transesterification process. In the initial stage, refined oil was gone through the acid catalyst esterification process followed by the transesterification reaction. The prepared methyl ester was confirmed and characterized using GC‐MS technique. The thermophysical and spray properties of the test fuels including density, viscosity, calorific value, cloud/pour point, Sauter mean diameter (SMD), and specific surface area (SSA) were also calculated. The experimental result showed a significant increase in ignition probability and heat conduction properties due to improved surface area/volume ratio. Also, lower evaporation time was noted for metal/carbon‐based nanoparticles doped biodiesel as compared with neat biodiesel.
