“…NO x emissions from biofuels are higher than that of diesel at all brake powers. The inbuilt oxygen present in biofuels is the major cause for higher NO x emissions (Devarajan et al 2017c). NO x emission was significantly lower for WOPOBDE1 and WOPOBDE2 than that of WOPOBD at all conditions.…”

“…Smoke value for WOPOBDE1, WOPOBDE2, and WOPOBD was lower than that of diesel. This is owing to the higher oxygen present in biofuel, which enhances the oxidation process (Joy et al 2017;Devarajan et al 2017cDevarajan et al , 2018. Further, the smoke emissions of WOPOBDE1 and WOPOBDE2 are lower than WOPOBD at all conditions.…”

“…HC emission for the base and modified fuels is lower than that of diesel at the same brake power. Surplus oxygen present in biofuels and water blends facilitates the combustion and reduce HC emissions (Devarajan et al 2017c;Joy et al 2017). Addition of water into orange peel oil biodiesel (WOPOBDE1 and WOPOBDE2) has reduced the unburned hydrocarbon emissions.…”

“…BTE of all test fuels increases with an increase in brake power. At higher brake power, the frictional and other unaccounted losses are lower which in turn contributed to the increasing trend of BTE, by minimizing exergy destruction (Devarajan et al 2017c(Devarajan et al , 2018. The brake thermal efficiency of diesel was higher than other test fuels (WOPOBDE1, WOPOBDE2, and 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.

“…shortened delay period which results in combustion getting more uniform followed by lessened peak pressure [5,6]. Moreover, from Table 2, we can observe that DIESEL fuel has improved calorific value which is responsible for consuming lowered fuel at combustion and high combustion efficiency of DIESEL is also a factor for shortened peak pressure [7,8].…”

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.

Biodiesel has emerged as a promising renewable fuel, which can help reduce dependency on fossil fuel and has potentiality to replace petrodiesel partially. Usage of biodiesel results in decreased carbon monoxide, hydrocarbon, and particulate matter emission. However, it has some drawbacks such as increased nitrogen oxides (NOx) emission, lower calorific value, and poor engine performance, which restrict wide usage of biodiesel as a potential substitute in compression ignition engine. There is a scope to overcome these problems by applying metal based nanoparticles (NPs) as fuel additive. This article reviews the preparation and stability of nanofluid and the effect of metal based NPs on fuel properties, combustion, performance, and emission characteristics. It has been concluded that inclusion of nanoadditives increases cetane number and calorific value of blended fuel. According to the most authors, metal based NP doped biodiesel blend enhances ignition characteristics, improves engine performance, and reduces emissions including NOx compared to biodiesel blend without additive. However, some concerns and challenges identified in this article need to be addressed to make this technology feasible for commercial application in near future.
