The shortage of fossil fuels is a significant political and economic issue that occurred due to global reliance on fossil fuels. The fuel characteristics of the produced diesel and biofuel (viscosity, density, cloud point, flash point, acid number, lower heating values, and pour point) are then determined. It is anticipated that using biofuel will result in higher fuel usage than using diesel fuel. This scenario also has an impact on the emissions. Biofuel has a higher density than diesel fuel, which has a detrimental impact on emissions and engine performance. It may be inferred that, while using the identical diesel engine for comparison, the effects of waste oil-derived biofuel are distinct from those of diesel fuel. Therefore, in order to achieve the best outcomes, it is crucial to develop new forms of biofuels. Nanomaterials (NMs), like copper oxides, titanium oxides, and aluminium oxides have been developed to be the most promising fuel additives for diesel engines in recent years. A significant amount of laboratory testing has been conducted up to this point to investigate the impact of using nano fuels on several aspects of diesel engine characteristics, particularly on hazardous emissions and engine performance (BSFC, effective power, BTE). This study provides an overview of the findings so far and the current situation regarding the use of nano fuels in diesel engines. Additionally, among the group of the most tested fuel additive nanoparticles, the best NMs/base fuel combinations are found based on two criteria that either involves all diesel engine parameters or simply diesel emissions. There are numerous techniques for improving engine performance. Nanoparticles can be used as catalysts in chemical reactions and feedstock retreatment processes to produce biofuels. According to the overall findings, adding nanoparticles significantly reduced the amount of fuel used for brakes by 20% to 23% when compared to biodiesel-diesel blends with and without the addition of alcohol. In addition to improving the combustion process and boosting the brake power by 2.5% to 4%, nanoparticles have a high thermal conductivity. Emission data revealed that while HC, CO, and PM emissions all dramatically decreased in most reviews, NO emissions increased by up to 55%.

“…There are several studies which revealed the use of different types of metallic oxide NPs as an additive to fuel blend. (Kumar, Dinesha, Bran et al, 2019;Sajeevan & Sajith, 2013;Yaşar et al, 2019). Kumar et al (Kumar, Dinesha, Bran et al, 2017) reported the use of 1% by volume of ferrofluid in B20 biodiesel resulted in maximum efficiency with reduced emissions.…”

Biofuels are one of the most sought-after renewable energy sources to overcome the current energy crisis in the world. Diesel blended with esters derived from oils has shown appreciable results for its use in compression ignition engines. In this work, B20 (20% biodiesel + 80% diesel by volume) fuel blend comprising 80% diesel and 20% biofuel extracted from waste cooking oil is used as a fuel. Two different metallic oxide nanoparticles (NPs), namely, cerium oxide (CeO 2 ) and aluminium oxide (Al 2 O 3 ) each having size of 30 nm, are dispersed in B20 biodiesel blend and used to investigate their combined influence on engine combustion. Experiments are conducted to study the engine exhaust emissions of a single cylinder four-stroke diesel engine running at constant speed of 1,500 rpm with varying engine loads. Experiments are carried out with B20 fuel and adding mixtures of CeO 2 and Al 2 O 3 nanoparticles in 50-30, 40-40 and 30-50 ppm, respectively, to B20 biodiesel blend. Responses recorded are the emissions of CO, HC, CO 2 , NOx and smoke. The results reveal that, on adding the nanoparticles, the engine observed a smooth combustion with reduction in the exhaust emissions compared to neat B20 biodiesel operation. B20 blend with 50 ppm of CeO 2 and 30 ppm of Al 2 O 3 nanoparticles showed lower exhaust emissions compared to other fuel blends. For the best fuel blend, CO, HC, NOx and smoke are reduced by 57.3%, 22.3%, 24.3% and 7.36%, respectively, compared to neat B20 operation.

“…This has been shown in Figure 13a,b for NOME20 and KOME20 respectively. Graphene oxide NPs contain higher oxygen contents that reduce the ignition delay during combustion, which helps in completing the combustion of fuels [44,45]. A maximum of 73.5HSU of smoke was recorded for diesel at full engine condition.…”

In the current research, the biodiesel was prepared from feedstocks of Neem oil and Karanja oil employing a single step direct transesterification method using acid-base catalysts simultaneously. The fuel properties of both Neem and Karanja biodiesel along with different biodiesel-diesel blends were studied and compared. Biodiesel produced from Neem oil was found better in terms of kinematic viscosity, calorific value and cloud point for all its blends with diesel compared to Karanja biodiesel-diesel blends. Experiments were conducted to study the effects of addition of graphene nano particles on fuel properties of biodiesel-diesel blends. The B20 biodiesel-diesel blend was selected, which was blended with graphene nano particles in different proportions (35, 70, 105 ppm) to get different stable and symmetric B20-nano blends. The fuel properties except kinematic viscosity were further improved with higher dosages of nano particles with the biodiesel-diesel blend. The performance and emissions tests were conducted on 4-stroke variable compression ratio diesel engine. Higher concentrated B20-nano blends of Neem (NOME20GO105) and Karanja (KOME20GO105) resulted in 31 and 30.9% of brake thermal efficiency, respectively, compared with diesel of 32.5%. The brake-specific fuel consumption (BSFC) was reduced by 10 and 11% for NOME20GO105 and KOME20GO105, respectively, compared to their respective B20 blends. Similarly, carbon monoxide (CO) was reduced significantly by 27 and 29% for NOME20GO105 and KOME20GO105, respectively.
