Emission analysis on the effect of nanoparticles on neat biodiesel in unmodified diesel engine

Abstract

Biodiesels derived from the mahua seeds are established as a promising alternative for the diesel fuel owing to its non-edible nature and improved properties. TiO nanoparticle in powder form is added to neat mahua oil biodiesel (BD100) to examine its effect on emission characteristics. TiO nanoparticle is chosen as an additive owing to its catalytic effect, higher surface energy, and larger surface to volume ratio. TiO nanoparticle with an average size of 60 nm was synthesized by sol-gel route. TiO nanoparticles are added with mahua biodiesel (BD100) at 100 and 200 ppm. Mahua oil biodiesel doped with 100 and 200 ppm of TiO nanoparticles are referred as BD100T100 and BD100T200. A constant speed diesel engine is employed for the experimental trail. Engine is fueled with diesel, BD100, BD100T100, and BD100T200, respectively. Experimental result confirmed that the modified fuels (BD100T200 and BD100T100) showed a significant reduction in all the emissions. Further, the addition of TiO nanoparticle (200 ppm) to mahua biodiesel gave respective reduction of 9.3, 5.8, 6.6, and 2.7% in carbon monoxide, hydrocarbon, nitrogen oxide, and smoke emissions when compared to neat mahua biodiesel.

Emission and performance study emulsified orange peel oil biodiesel in an aspirated research engine

“…The modified fuel which consists of base fuel, water and surfactants are prepared by altering its proportions. For blending purpose, ultrasonicator, and magnetic stirrer were employed (Pandian et al 2017). Various properties of prepared and modified fuels are established by ASTM techniques.…”

Effect of cerium oxide nanoadditive on the working characteristics of water emulsified biodiesel fueled diesel engine: An experimental study

“…In addition to that, an absence of aromatic and sulphur, and an enriched oxygen nature promote complete combustion and reduce the tendency of soot and CO emissions [6,7]. Meanwhile, the higher NOx emission and kinematic viscosity, and lower oxidation stability and volumetric energy capacity are identified as an important drawback of biodiesel-fueled Diesel engine and had to be overcome for common use [7,8].…”

Performance and Emission Analysis of Diesel Engine Using Thermal Barrier Coating and Addition of Cerium Oxide Nanoparticles to Palm Biodiesel

“…Unburned hydrocarbon emissions were reduced compared with a base engine on an average of 14, 21.4 and 26 ppm in neat palm biodiesel, 30 ppm and 60 ppm cerium oxide mixed palm biodiesel used TBC engine respectively (Anbarasu and Karthikeyan, 2016). This reduced hydrocarbon emission happened due to TBC engine maintaining a high heat energy in the chamber, it absorbed deposits of oil in the combustion chamber wall, usage of one of thermal barrier coated material of alumina and cerium oxide nanoparticles promotes the oxidation process with hydrocarbon (Pandian et al, 2017).…”

“…There was a substantial reduction in the SFC for TBC engine at an average of 11.86%. It is due to high combustion temperature maintained in the combustion chamber employing YSZ and alumina thermal barrier coating materials which result in reduced the heat flow from combustion chamber (Pandian et al, 2017). In addition, 30 ppm and 60 ppm cerium oxide mixed palm biodiesel used in TBC engine caused a reduction in fuel consumption on an average of 16.92% and 20.57%, respectively (Pandian et al, 2018).…”

“…Alumina has advantages of high corrosion-resistance, high hardness and absence of oxygen-transparency. But it has the disadvantages of phase transformation occurring at 1273 K, high thermal conductivity and very low thermal expansion coefficient (Pandian et al, 2017). So YSZ and alumina coating cannot individually be the best thermal barrier coating materials.…”
