Effect Of n-amyl alcohol/biodiesel blended nano additives on the performance, combustion and emission characteristics of CRDi diesel engine

Abstract

This paper deals with the study on the in uence of the effects of iron oxide nanoparticle additives when added to ternary fuel (diesel + Mahua methyl ester + Pentanol) on the emission, combustion and performance characteristics of a four stroke, single cylinder, common rail direct injection diesel engine working at a constant speed and varying operating scenarios. Doping is done in various proportions to the nanoparticle additives with the help of a homogenizer and ultrasonicator where the cationic surfactant used is CTAB (cetyl trimethyl ammonium bromide). Iron oxide nanoparticles were used as additives in fuel in the dosages of 40 ppm, 80 ppm & 120 ppm respectively and TF (Ternary fuel) is obtained by mixing 10% pentanol, 20% Mahua and 70% diesel together is used for the experimental study. The experimental study revealed that while using the nanoparticle additives blended ternary fuel (i.e., TF80) the number of harmful pollutants like smoke (5.38%), HC (6.39%), carbon monoxide (10.24%) and NO x etc. has reduced to a considerable extent and there was a commendable improvement in the BTE by 8.8%. So, we can summarize that when ternary fuel and nano additives are blended together the combustion and performance of the engine was improved considerably and pollutant emissions were decreased.

Computational optimization of engine emissions and performance of a CI engine powered with biogas and NiO nanoparticles doped diesel

“…It was observed that HC drops when there is a rise in NDR. It is due to a substantial amount of fuel oxidized owing to the fuel's nanoparticle content 35 . For all the load levels, an approximate decrease in HC of 5.5% and 9% for the NDR 25 ppm and NDR 50 ppm, respectively, were observed compared to HC registered for non‐doped diesel fuel.…”

Synthesis, stability, and emission analysis of magnetite nanoparticle-based biofuels

“…10 Effect of heat release rate on nano-added diesel or biodiesel in Fig. 11D [193], the addition of iron oxide nanoparticles to the ternary fuel reduced the delay period as compared to pure diesel. The shorter delay period is attributable to improved atomization due to the high surface tension and calorific value of the blend.…”

Combustion and secondary atomization behavior of nanofuel droplets laden with hematite, magnetite and lanthanum orthoferrites nanoparticles**

“…NP additives in nanofuels are known for their secondary atomization phenomena during combustion and their catalytic activity, which is often highlighted in engine performance tests [43,65,66]. Secondary atomization mechanisms are mostly related to particle concentration and the tendency of particles to form aggregates during combustion.…”

“…Metal and metal oxide NPs have been extensively studied as potential metal fuel additives for diesel‐biodiesel blends, explosives, and pyrotechnics, with their catalytic activity and high oxygen content [1–6]. Aluminum, magnesium, lithium, bismuth, titanium, iron, tin, cerium, and their oxides have been investigated to accelerate oxidation, reduce ignition delay times and improve combustion rates [7–14].…”
