“…Another possible reason of this increase in CO emission is the lower cetane number of ethanol fuel which could induce an increase in the combustion delay, especially at low engine speed. Similar results have been reported many researchers in the relevant literature [12,14,[16][17][18][19][20]23,24].…”

“…In addition, the lower cetane number of ethanol fuel leads to longer ignition delay, and hence the combustion temperature might increase in the premixed combustion mode. Similar behavior for NOx emissions has been obtained in the relevant literature by Goldsworthy [19]. A maximum reduction in NO emission of about 56% has been obtained at engine speeds of 800 rpm and 1000 rpm for 50% ethanol/water mixture.…”

“…Although the existence of ethanol would increase the oxygen available for combustion, the effect of latent heat of vaporization seems to be prevailing. Majority of the researchers reported that the increase in HC emission is accompanied with CO emission [1,11,14,[16][17][18][19][20][21]23,24]. It seems that the reasons behind the formation of HC during combustion are the same that leads to CO formation.…”

“…Only few number of research work in the relevant literature [16,19,[26][27][28][29][30][31][32] has been done on fumigation of ethanol/water mixtures. In addition, to the best of the author's knowledge, there is no study that was performed to elucidate the second law analysis of a diesel engine fumigated with ethanol/water mixtures.…”

“…Goldsworthy [19] tested the effects of fumigating vaporized ethanol-water mixtures (93%, 72% and 45% by mass) in a constant speed and various loads (BMEP of 17 bar and 20 bar) diesel engine operating with two stage injection. Small improvement was detected in brake thermal efficiency with 72% mixture at a BMEP of 20 bar.…”

The present study tested newly formulated hydrous ethanol–diesel‐emulsified fuel infused with nano‐sized γ‐Al2O3 particles on a turbocharged CRDI 4‐cylinder stationary diesel engine. W5H5, W5H10, and W10H5 test fuels were inducted into engine cylinders at a fixed engine speed of 2000 rpm. These test fuels significantly improved their physicochemical properties, with an 8.80% increase in gross calorific value and a 6.52% growth in cetane index. W5H10 exhibited a 16.01% increment in brake thermal efficiency and a 22.22% decrement in brake‐specific fuel consumption. Also, this fuel reported an 8.64% higher in‐cylinder pressure and a 40.71% higher heat release rate. W5H10 test fuel noted a 50% dip in carbon monoxide emissions and an 84.56% lower smoke opacity than diesel. W5H5 fuel reported 33.33% lower unburnt hydrocarbons than diesel at full load. W10H5 fuel observed an 88.46% drop in nitrogen oxide emissions compared with diesel at 10% engine load. The author found W5H10 the most suitable fuel for diesel engines with no modification costs.

The present numerical analyses are related to the cooling of a hybrid electric vehicle (HEV) battery module by water-ethanol mixture. The fluid is passed through a cold plate consisting of two rectangular channels of 0.01 m depth, 0.015 m width, and 0.15 m length. The battery module is represented by a heater placed below the cold plate. The single-phase pressure drop and single-phase heat transfer coefficient for water, water-ethanol mixture of mass fraction of 25%, 50%, and 75%, and ethanol are determined numerically for different heat fluxes of 10, 15, 20, and 25 kW/m 2 and different Reynolds numbers 500, 1000, 1500, 2000, and 2500. To solve the Navier-Stokes equation, the pressure correction method was used and to solve the energy equation, the Lax-Wendroff explicit method is used. Numerical results obtained for water are compared with the literature correlations. The friction factor for water deviated by an average of 8.02% from the Lewis and Robertson equation. The Nusselt number for water deviated by 7.35% from the Churchill and Ozoe equation at lower Reynolds number 500 and at higher Reynolds number 2500, Nusselt number deviated by 13.68% from the Stephan equation. The results showed that the heat transfer coefficient increased with an increase in Reynolds number and heat flux. The effect of the increase in Reynolds number is more significant than the increase in heat flux. At higher ethanol mass fraction and higher Reynolds number the heat transfer coefficient increased with heat flux when compared to water. There is no significant decrease in heat transfer coefficient with an increase in ethanol mass fraction. The pressure drop increased and the heat transfer coefficient decreased with an increase in ethanol mass fraction.
