“…Many investigations have proven that adding additives (metal-based) in powder form to BD facilitates as a catalyst in boosting the engine combustion and performance and improves its fuel properties. − Nanoadditives alter the chemical composition of BD and enhance the oxidation characteristics. Nanoadditives also aid the engine combustion and performance characteristics of fuel .…”

More requirements for diesel fuel and a huge rise in air pollution, owing to the surplus usage of diesel fuel, give us a prospect to discover environmentally friendly and clean fuels for the existing unmodified diesel engines. The present work is aimed to analyze the combustion, performance, and emission characteristics of a neat palm oil biodiesel (POBD)-fueled diesel engine with silver oxide (Ag2O) as a additive in various mass fractions (5 and 10 ppm), and the results are compared to conventional diesel. Experiments were conducted in a natural aspirated, two-cylinder diesel engine at a constant speed and compression ratio of 2400 rpm and 17:1, respectively. Ag2O was added with neat POBD using an ultrasonicator. The experimental investigation on the diesel engine reveals that the addition of Ag2O nanoparticles to palm oil mill effluent (POME) resulted in enhancement in ignition characteristics because of the enhanced surface area/volume ratio. In addition, the addition of Ag2O nanoparticles to POME resulted in enhancement in brake thermal efficiency with a reduction in brake specific fuel consumption. The experimental results also show that the Ag2O nanoparticles promote an improved level of hydrocarbon, carbon monoxide, smoke, and nitrogen (NO x ) emissions.

“…Addition of Al2O3 nano-additives at 25ppm and 50ppm fraction to PBD resulted in improved peak pressure which could be perhaps attributed to the improved thermal conductivity of the resulting nano-fuel mixture [9,4]. The higher thermal conductivity of nano-fuel causes the fuel combustion to begin earlier thus resulting in higher in-cylinder peak pressure.…”

The current research work emphases on analysing the characteristics of combustion, performance, and emissions of Polanga Biodiesel (PBD) fuelled single cylinder diesel engine with Al2O3 nano-additives added at concentration of 25 ppm and 50 ppm. The results were compared with the baseline diesel fuel at varying engine loads (25%, 50%, 75% and 100%) in a agriculture based single cylinder diesel engine of 17.5 Compression ratio at constant engine speed of 1500 rpm. Al2O3 nano-additives were blended with PBD using magnetic stirrer and ultrasonicator. Experimentation results revealed that, the nanoparticles addition in PBD improved the combustion and emission characteristics of base fuel due to higher surface area to volume ratio of nano-additives. Moreover, Al2O3 nanoparticles addition enhanced the brake thermal efficiency (BTE) and lowered the brake specific fuel consumption (BSFC) by 6.58% and 7.38% respectively. Subsequently, the emissions of HC, CO, NOx and smoke opacity were improved with the addition of fuel borne additives in PBD owing to improved combustion efficiency.

“…Plasma spraying thermal barrier coating is the best method for coating a diesel engine combustion chamber. Cerium oxide promotes the oxidation for reduction of CO emission and absorbs oxygen for reduction of NO x emission (Yuvarajan et al, 2016b;Devarajan et al, 2018c). It also burns off the carbon particles deposited in the cylinder wall region which results in reduction of the HC emission (Velliyan et al, 2017).…”

This work investigates the effect of thermal barrier coating and addition of cerium oxide nanoparticles to the palm biodiesel fuelled diesel engine. The combustion chamber parts of cylinder liner and piston were coated 200 and 100 micron thickness respectively using equal percentages of Yittria Stabilised Zirconia (YSZ) and alumina powder in plasma spraying technique. The 30 ppm and 60 ppm of cerium oxide (IV) nanoparicles were added to the palm biodiesel fuel separately. The performance and pollution parameters were analysed initially using a thermal barrier coated (TBC) engine with neat palm biodiesel. Cerium oxide (IV) nanoparticles were then added to the palm biodiesel and their effects were compared with the base engine. The final performance results showed reduction in the specific fuel consumption on an average of 11.86%, 16.92% and 20.57%, while brake thermal efficiency was increased by 3.21%, 4.28% and 4.82% in neat palm biodiesel fuel, 30 ppm and 60 ppm CeO 2 mixed palm biodiesel fuel used TBC engine respectively. Carbon monoxide and unburned hydrocarbon emission were reduced by 2.2% and 3.7% and nitrogen oxide emission was increased by 1.7% for TBC engine. However, the use of oxygen denoting catalyst of cerium oxide nanoparticles caused a 2.4% reduction in nitrogen oxide emission.
