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.

“…confirmed that pentanol addition lowered biodiesel HC and CO emissions. Kishore Pandian et al (2017) also agreed with the result stating that the addition of pentanol to biodiesel fuel lowers its NO x emissions. Radhakrishnan et al (2018) evaluated the impact of adding different volumes of pentanol to palm biodiesel in a research engine.…”

This work examines the effect of butanol as an oxygenated additive to lower carbon monoxide, smoke, nitrogen oxide and hydrocarbon emissions and to improve the performance aspects of Calophyllum inophyllum (Punnai) biodiesel. Singlecylinder, oil-cooled compression ignition engines are employed in this work. Neat Punnai biodiesel (P100) is blended with butanol at 10% and 20% by volume and labelled as B10P90 and B20P80, respectively. Methanol and alkaline catalyst (KOH) were used for the transesterification process for biodiesel production. The transesterification technique yielded 88% biodiesel from raw Punnai oil. Engine tests resulted in lower CO, smoke, NO x and HC emissions when fuelled with both butanol blends when compared to P100. In addition, BSFC (brake-specific fuel consumption) reduced and BTE (brake thermal efficiency) increased with the inclusion of butanol blends (B10 and B20) to neat Punnai biodiesel.

“…BSFC of diesel was lower than other test fuels (WOPOBDE1, WOPOBDE2 and WOPOBD). This is due to the higher calorific value of diesel (Kishore Pandian et al 2017;Devarajan et al 2018). BSFC for WOPOBDE1 and WOPOBDE2 was lower than neat WOPOBD.…”

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.
