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.

“…In this study, Span 80 as a nonionic surfactant was used for emulsifying water and biodiesel. Earlier reported literature is the motivation for choosing Span 80 as a surfactant (Devarajan and Madhavan 2017;Vellaiyan and Amirthagadeswaran 2017a;Arul Gnana Dhas et al 2018). This study employed four fuels, namely diesel, waste orange peel oil biodiesel (WOPOBD), fuel comprising 4% (in volume) of water, 94% (in volume) of neat waste orange peel oil biodiesel and 2% (in volume) span 80 (WOPOBDE1), and fuel comprising 8% (in volume) of water, 90% (in volume) of neat waste orange peel oil biodiesel and 2% (in volume) Span 80 (WOPOBDE2) in a constant speed compression ignition engine.…”

This study paves the way on reducing smoke emission and NO x emissions of research diesel engine by detailing the effect of water addition in biodiesel. Fuel samples were prepared with different concentrations of water in orange peel oil biodiesel (94% waste orange peel oil biodiesel + 4% water + 2% Span 80 (WOPOBDE1) and 90% waste orange peel oil biodiesel + 8% water + 2% Span 80 (WOPOBDE2). Span 80 was employed as a nonionic surfactant, which emulsifies water in biodiesel. Experimental results revealed that the nitrogen oxides and smoke emission of orange peel oil biodiesel emulsion were reduced by 11%-19% and 3%-21%, respectively, compared to that of neat orange peel oil biodiesel (WOPOBD). In addition, the introduction of orange peel oil-water emulsions in the diesel engine considerably reduced the emissions of unburned hydrocarbons and carbon monoxide. The overall hydrocarbon emission of WOPOBDE2 was 12.2% lower than that of WOPOBD and 16.3% lower than that of diesel. The overall CO emission of WOPOBDE2 was 17% lower than that of base fuel (WOPOBD) and 21.8% lower than that of diesel. Experimental results revealed that modified fuel had higher brake thermal efficiency and lower brake specific fuel consumption than that of base fuel at all engine brake power levels.

“…Therefore, carbon monoxide emissions were reduced to a low level in all load conditions of TBC engine compared with base engine. indicates neat palm biodiesel used in TBC engine producing higher NO x emission compared to the uncoated engine (Arul Gnana Dhas et al, 2018). It is due to TBC engine maintaining higher combustion temperature restricted to dissipation of heat energy to cooling water.…”

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.
