“…As a result, it is possible to create an appropriate regression equation that will offer a highly accurate and precise prediction of the Q i from the chosen combinations of the control factors. The non-symmetric bell-shaped histogram uses normal distribution for the analysis and gives the fit of the data available (Hasnain et al, 2023; Li et al, 2023; Thejas et al, 2022). The versus fits show that the residuals are randomly distributed having constant variance and the same has been in accordance with (Singh, Sharma, et al, 2021).…”

The excessive use of single-use plastic products in modern life has caused severe environmental, social, economic, and health consequences globally. Mostly all plastics manufactured are one-time-use materials that end up in landfills or as unmanageable garbage. This situation has led to the production of around 400 million tonnes of plastic waste per year, and if this trend continues, global production will reach up to 1100 million tonnes by 2050. India alone produced over 34.7 lakh tonnes per annum (TPA) of plastic waste, with only half of it being recycled or co-processed. As such, there is an urgent need to develop ways to reduce plastic waste. One possible solution is the use of waste plastic biofuel in engines, which has been shown to have promising results. The study aimed to analyse waste plastic oil using (Gas Chromatography Mass Spectrometry) GC-MS and (Fourier Transform Infrared Spectroscopy) FTIR analysis to identify its chemical composition. The findings of the study revealed the presence of various chemical compounds, such as alcohol, hydroperoxide, carbonyl acid groups, ester, carboxylic acid, ketones, aldehyde groups, and others. FTIR analysis confirmed the presence of alcohol, hydroperoxide, carbonyl acid groups, methyl and methylene groups, ester, carboxylic acid, ketones, aldehyde group, symmetric and asymmetric C-H bending, C-O stretch for ethers, carboxylic acids, and esters, and=C-H bending out for alkenes. The study further explains that primary plastic consumption and packaging lifetime have a significant impact on plastic waste generation. The research indicates the need to explore alternative ways to recycle and dispose of single-use plastics to mitigate its negative impact on the environment. Furthermore, this study analyses the statistical optimisation method to develop a model fit for engine behaviour using waste plastic biofuel on a single-cylinder (common rail direct injection engine) CRDi diesel engine using the (weighted aggregated sum product assessment) WASPAS approach. Additionally, the objective is to develop a model that can optimise the engine's performance while using waste plastic biofuel. The uncertainty analysis demonstrated that the experiment was carried out with a high degree of accuracy and the results were reliable. The study employed the WASPAS methodology to evaluate the performance of different (waste plastic oil) WPO samples, and the results showed that the optimal parametric setting to obtain the desired responses can be achieved with a fuel blend of 5%, load of 21 bar, and speed of 2000 RPM. However, the results demonstrate that the use of waste plastic biofuel can significantly improve engine performance, and the proposed optimisation model can accurately predict the engine's behaviour. The regression equation that was formulated showed a reasonable degree of agreement between the actual experimental results and the predicted values, thereby indicating the reliability of the experiment. Significant effects were observed from fuel blend, and speed, whereas load did not make a substantial contribution. The findings regarding the effect of parameters suggest that a reduction in fuel blend, and engine speed resulted in a decline in the performance index, while variations in load had little impact. The relationship between load and speed demonstrates that a rise in load and a reduction in speed contributed to enhanced combustion and a higher performance index. The interaction among fuel blend and speed, with a particular emphasis on the significance of reduced fuel blend and speed values in order to optimise the performance index. The findings of the analysis underlined the vitality of process parameters, specifically fuel blend and speed, wherein speed exhibited a significant impact on the outcomes. The study concludes that the use of waste plastic biofuel in engines can be an effective way to reduce plastic waste while improving engine performance. This study's findings can be applied to various engines to improve their performance while reducing plastic waste. All in all, the outcomes of the study make a substantial contribution to the advancement of scientific information regarding the properties of waste plastic oil as well as its combustion characteristics. This expands the potential for advanced breakthrough innovations in sustainable energy solutions and the conservation of the environment.

“…Additionally, using an ultrasonicator and a mechanically controlled conventional homogenizer, nanoparticles were combined with diary scum oil methyl ester (DiSOME) in the mass fraction range of 10 to 30 parts per million (ppm) in increments of 10 [109]. The effects of Al 2 O 3 NP on the ignition characteristics and engine outgas levels of a single cylinder, four-stroke, directinjection diesel engine operating in dual fuel mode with producer gas (PG) [112] have been studied in the following section of the work [113]. Engine testing revealed that Al2O3based NF and PG operation trials increased brake thermal efficiency by 11.5%, reduced smoke by 23.2%, and reduced hydrocarbon (HC) and carbon monoxide emissions by 18.2-21.4% (CO).…”

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%.

One of the main motivations behind the development of alternative fuels is to protect the environment and advance sustainability. Biodiesel, a specific potential substitute, improves the overall performance of diesel engines. Therefore, this work examines how well biodiesel performs in terms of engine fuel consumption and emission efficiency. In the proposed work, diesel and soup nut oil are combined at B30, B60, and B90 ratios. To boost thermal stability, the TBC is also used over the piston.Additionally, Di-Tertiary Butyl Peroxide, an ignition promotor, is introduced. Different coatings, including yttria-stabilized zirconia (A2), magnesium-stabilized zirconia (A1), and gadolinium zirconate, were used in the experimental process (GD). The experimental process is performed with the help of an experimental setup. The results are showed the performance of the proposed biodiesel along with the ignition promoter. The validation of the proposed biodiesel is performed in terms of estimating the parameters such as indicated mean effective pressure (IMEP), brake thermal efficiency (BTE), and specific fuel consumption (SFC). Furthermore, the emission level of carbon monoxide (CO), hydrocarbon (HC), and oxidization of nitrogen (NO x ) are also measured to validate the performance of the proposed bio-diesel.
