“…Many nanosized materials like CNT cerium oxides when blended with fossil diesel, tends to reduce thermal NO x emissions 27,33 . Also, Sarvestany et al 34 proposed that use of magnetic particles tends to lower NO x at varying engine loads with a mediocre decrement of 56% at 0.4% nanofluid and 67% at 0.8% nanofluid. Similar results were observed in Figure 10 which shows the experimentation of increase of braking torque and CR raises the amount of thermal NO x emissions for all levels of NiO blended NB25 fuels.…”

The utilization of biodiesel‐diesel blends in compression ignition (CI) engines are a viable option for the current energy crises. But due to better combustion features of biodiesel‐diesel blends leading to high NOx release from engine exhaust hinders the use of such blends. Usually all of the harmful exhaust emissions like HC and CO reduces marginally, except nitrogen oxides at higher compression ratios with biodiesel blended fuel. The present paper focuses on the study of variation of compression ratio and use of NiO nanoparticles in neem biodiesel‐diesel mixture (NB25) at different braking loads. A total of four test fuels of NB25 blend were prepared having nickel oxides at different concentration levels of 25, 50, 75, and 100 ppm. The current findings reveal that the use of 75 ppm of NiO in NB25 blend reduces the amount of thermal NOx by 6.2% compared to the absence of nanoparticles. Also, the performance parameters such as brake thermal efficiency improved by 2.9% and brake specific fuel consumption reduced by 1.8%. The presence of 75 ppm of NiO in NB25 not only shows best performance and also lower harmful emission.

“…Based on the above, most of the researchers conducted their experiments with metal nanoadditives [10], metal oxide nanoadditives [11e14], magnetic nano fluid additives [15,16] and water diesel nanoparticle, emulsion [17e19], water diesel carbon nano tube emulsion [20], and nano organic additives [21,22] to the diesel fuel. Very few researchers worked, on the use of nanoadditives to biodiesel for the enhancement of the performance and emission characteristics.…”

a b s t r a c tExperimental investigation was carried out to study the combustion, engine performance and emission characteristics of a single cylinder, naturally aspirated, air cooled, constant speed compression ignition engine, fuelled with two modified fuel blends, B20 (Dieselesoybean biodiesel) and dieselesoybean biodieseleethanol blends, with alumina as a nanoadditive (D80SBD15E4S1 þ alumina), and the results are compared with those of neat diesel. The nanoadditive was mixed in the fuel blend along with a suitable surfactant by means of an ultrasonicator, to achieve stable suspension. The properties of B20, D80SBD15E4S1 þ alumina fuel blend are changed due to the mixing of soybean biodiesel and the incorporation of the alumina nanoadditives. Some of the measured properties are compared with those of neat diesel, and presented. The cylinder pressure during the combustion and the heat release rate, are higher in the D80SBD15E4S1 þ alumina fuel blend, compared to neat diesel. Further, the exhaust gas temperature is reduced in the case of the D80SBD15E4S1 þ alumina fuel blend, which shows that higher temperature difference prevailing during the expansion stroke could be the major reason for the higher brake thermal efficiency in the case of D80SBD15E4S1 þ alumina fuel blend. The presence of oxygen in the soybean biodiesel, and the better mixing capabilities of the nanoparticles, reduce the CO and UBHC appreciably, though there is a small increase in NO x at full load condition.

Diesel engine play important role in the field of commercial transportation and agricultural machinery on account of its superior fuel efficiency. Due to shortage of diesel fuel and its increasing cost as well as hazardous emission emitted by diesel engine, th use of biodiesel and its blends has gained importance over the past two decades due to its environmental and economic benefits. Many countries are evaluating a variety of alternative fuels for use in motor vehicles in an attempt to reduce greenhouse emis warming and to improve the energy security of the nations. Blended fuel is a replacement for the diesel fuel in CI engines due to its significant environmental benefits. The use of blended fuel leads to reduction in particulate matter, hydrocarbon and carbon monoxide emissions that decrease in fuel consumption and the nitrous oxide emission on diesel engine without any modification. The addition of Nano particles with blended diesel fuel increases the efficiency and decreases the emissions. Metal oxides such as alumina, titanium oxide, cerium oxide in the form of nano particles can be used to increase the efficiency as well as to decrease emission. In this review paper work has been done to demonstrate the effect of @ IJTSRD |
