“…Also, the brake thermal efficiency increased by 15.05% with the addition of nano-Fe 2 O 3 at a concentration (100 ppm) wt% for fuel (D80:B20), compared to diesel fuel, this is due to the improvement of the cetane number and calorific value of fuels. The brake thermal efficiency for fuel (D80:20:N100 ppm) increased with changing air humidity of the intake into the engine of (RH65%) by 17.63%, compared to pure diesel, due to that the increased humidity of the air into the intake of combustion chamber leads to a delay in the ignition period, as the longer the ignition period leads to the formation of a homogeneous air-fuel mixture increasing the rate of heat release [17,18].…”

“…The unburnt hydrocarbon decreased by 73.72% for fuel (D80:20:N100 ppm) with changing the air humidity of the intake into the engine of (RH65%), compared to pure diesel. This is due to increasing the humidification of the inlet air which causes the increase of the percentage of oxygen atoms in the cylinder and obtaining a homogeneous concerning fuel, hence more complete combustion occurs [16][17][18].…”

This is due to that increasing the humidification of inlet air causes the water droplet to absorb some heat it leads to lower peak temperatures in the combustion zone that reduce the formation rate of NO x [16,17,18].…”

The effect of humidification of the air on the performance of a compression ignition engine operating on diesel, biodiesel with nano additives was investigated. The experiment was carried out on a single-cylinder, four-stroke, naturally aspirated water-cooled, direct injection Ricardo (E6/US) diesel engine at a constant speed of 1800 rpm, and varying loads. A mixture of Biodiesel (waste cooking oil) and diesel fuel by four ratios (B5, B10, B15, and B20) was used in the experiment. Besides, five concentrations of Iron oxide nanoparticles (Fe2O3, with particle size 20 nm) as fuel-additives were prepared (10 ppm, 30 ppm, 50 ppm, 70 ppm, and 100 ppm), and added to the test fuels (Bio-Diesel). Taguchi Method by DOE was used for the optimization in this investigation. The results of Taguchi Method experiments identified the biodiesel (B20), nano additive (100 ppm), relative humidity (65%). The experimental results manifested that BTE improved by 17.62% and BSFC decreased by 12.72%, while NOx and PM reduced by 8.45%, 24.17%, respectively.

“…Feedstocks for biofuel undergo a transesterification reaction to produce biodiesel along with a byproduct, glycerine ( Figure 1) Shahabuddin et al, 2013;Mofijur et al, 2014;Mofijur et al, 2016;Rizwanul Fattah et al, 2020). Biodiesel fuels effectively contribute to reducing emissions like carbon dioxide (CO 2 ), carbon monoxide (CO), particulate matters (PM), and total hydrocarbons (THC) when used in diesel engines at acceptable diesel-biodiesel blend ratios (Abdollahi et al, 2020;Mahlia et al, 2020). Although biodiesel typically reduces a variety of emissions, the general trend of combustion of this fuel shows an increase in the emission of oxides of nitrogen (NOx) at all loads of engine operation (Szybist et al, 2007;Lapuerta et al, 2008;Palash et al, 2013;Sahu et al, 2013;Lanjekar and Deshmukh, 2016).…”

Biodiesels are renewable fuel that may be produced from various feedstock using different techniques. It is endorsed in some countries of the world as a viable substitute to diesel fuel. While biodiesel possesses numerous benefits, the cold flow properties (CFP) of biodiesel in comparison with petro-diesel are significantly less satisfactory. This is due to the presence of saturated and unsaturated fatty acid esters. The poor CFP of biodiesel subsequently affects performance in cold weather and damages the engine fuel system, as well as chokes the fuel filter, fuel inlet lines, and injector nozzle. Previously, attempts were made to minimize the damaging impact of bad cold flow through the reduction of pour point, cloud point, and the cold filter plugging point of biodiesel. This study is focused on the biodiesel CFP-related mechanisms and highlights the factors that initialize and pace the crystallization process. This review indicates that the CFP of biodiesel fuel can be improved by utilizing different techniques. Winterisation of some biodiesel has been shown to improve CFP significantly. Additives such as polymethyl acrylate improved CFP by 3-9 ° C. However, it is recommended that improvement methods in terms of fuel properties and efficiency should be carefully studied and tested before being implemented in industrial applications as this might impact biodiesel yield, cetane number, etc.

The automotive sector is one of the top energy consumers globally compared with any other sector where oil plays the main role. According to http://statista.com (an online platform that displays the stats on oil consumption and reserves), in 2016, the demand for crude oil was about 85.3 million barrels per day worldwide. In 2019, the demand almost reached 100 barrels per day, and then it was reduced to 91 million per day during the 2020 global COVID‐19 crisis. However, it was predicted that the global crude oil requirements will exceed 100 million barrels per day by 2023 and will continue to raise. Also, geographically, not all countries worldwide have the oil reservoirs or the technology to extract oil from the reservoirs. Although the oil demand worldwide is increasing every year, researchers have estimated that there are only 47 years of oil left on the planet earth if the current oil consumption will raise this way. Researchers are looking for finding alternative fuels, such as electrochemical energy (electric vehicles), biodiesel, electricity, ethanol, hydrogen, natural gas, propane, emerging fuels, or the use of such fuels in the existing engines to minimize the use of nonrenewable energy resources. However, researchers are also looking more at fuels based on hybrid nanoparticles added to emulsified fuels. Due to the limitations of utilizing electrochemical energy or biofuels include high charging time, limited millage, harmful exhaust emissions, complicated production process, engine efficiency, the cost of fuel, and the advantages over hybrid nanoparticles added emulsified fuels than biofuels. Hence, after going through numerous researches, in this present experimentation, “hybrid nanoparticles (MgO and Al2O3) added water‐in‐diesel emulsion” are formulated to enhance the quality of emission and improve the performance of the compression ignition engine. The best combination of diesel, MgO, and Al2O3, a water‐in‐diesel (W/D) emulsion blend, is proposed. The results were further validated using deep neural network‐based spotted hyena optimization (DNN‐SHO) prediction and compared with traditional machine learning approaches artificial neural network (ANN), convolution neural network (CNN), regression‐based network (RBN), recurrent neural network (RNN), and DNN. As a result, the best proportions of the proposed nanoparticles added into the W/D bend are identified to be 10% W/D, 50 ppm of MgO, and 50 ppm of Al2O in terms of engine performance and emission characteristics brake thermal efficiency 30.7%, brake‐specific fuel consumption 0.29 kg/kW‐h, CO 0.027 vol%, NOx 855 ppm vol, and HC 12 ppm vol. Besides this, the DNN‐SHO‐based validated outcomes are in good agreement with the experimental values and outperformed other traditional approaches ANN, CNN, RBN, RNN, and DNN used in this study.
