“…Reduction in UHC emissions by 9.07% at maximum load for B20T50DMC10 blend than diesel fuel. The reduction in UHC emissions is owing to the higher surface to volume ratio of nano additives, higher oxygen content in the blend, and shorter ignition delay [31,34]. Similar results are shown in other studies [43,44].…”

“…It is noticed from the graph that maximum BSFC is seen for B20 blend owing to higher viscosity, lower calorific value, and oxygenated nature of biodiesel blend [31,37]. In contrast, the dispersed nano additives and oxygenated additives showed reduced BSFC due to modified fuel properties [34]. Maximum reduction in BSFC is observed as 17.64% at full load for B20T50DMC10 blend compared to B20 sample.…”

“…Whereas, B20 with the addition of nano and DMC additives showed higher values against diesel and B20 blend, which is mainly attributed to micro explosion phenomenon and higher thermal conductivity of nano additives that causes maximum heat transfer during ignition delay. Moreover, the surface-tovolume ratio of nano additives improves BTE [31,34]. Nevertheless, the addition of DMC oxygenated additives reduced viscosity which 6.13% at maximum load condition for B20T50DMC10 blend compared to B20 blend.…”

“…and other blends due to the combustion temperature, accessibility of oxygen in the combustion zone. NOx emissions can be minimized with the addition of nanoparticles which improves catalytic action and the ability of nano additives to carry away the nitric oxide [31,34]. Maximum reduction in NOx is observed as 6.53% at full load for B20T50DMC10 than B20 blend.…”

In the current research, the engine performance, combustion, and emission parameters of biodiesel mixture 20% Tamarind oil methyl ester and 80% Diesel (B20) with the inclusion of titanium dioxide (TiO2) in different concentrations (25.50 and 75 ppm) and 10% v/v dimethyl carbonate (DMC) as fuel additive investigated using a single-cylinder, 4-stroke, direct injection (DI), compression ignition (CI) engine. The nano fuel blends were prepared through the ultrasonication process. The ratio of 1:4 TiO2: QPAN80 was produced higher stability and consistency out of five trials. TiO2 were characterized using FESEM, HR-TEM, Fourier Transform Infrared (FTIR), and X-Ray diffraction. Fuel properties were determined as per the ASTM standards. Engine tests were carried out to determine the engine performance under varied loads such as 25, 50, 75, and 100% while keeping a uniform speed of 1500 rpm. The maximum reduction in BSFC, CO, HC, and NOx were found to be 17.64%, 9.49%, 7.81%, and 6.53%, and the increased BTE was observed to be 6.13% for B20T50DMC10 compared to B20 blend at full load. Thus, the combined effect of TiO2 and DMC served excellent engine performance, combustion, and emission characteristics in CI engine operation.

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.
