“…Production of CO emission in VCR CI engines is affected by a variety of factors including engine running conditions, type of fuel used, and so on. CO emission indicates incomplete combustion its formation takes place when the burning of fuel takes place at low temperatures and with insufficient air 48–52 from Figures 9A–C and 10A–C it has been discovered that when load increases Co emission reduces regardless of IT or CR. Figure 9A–C shows a graph of CO emission versus load at various ITs from Figure 9B it has been found that increasing the CR reduces CO emission regardless of IT, whereas minimum CO emission 0.026 vol% was observed with standard IT, that is, 23° bTDC at CR21 with B20 biodiesel and it is 40.90% lower than that of diesel.…”

The manuscript addressed experimental work related to microalgae‐based biodiesel blend B20, that is, 20% algae biodiesel and 80% diesel, as an alternative fuel as a possible source to power diesel engines. The physiochemical characteristics of this B20 blend were almost in line with diesel fuel as per American Society for Testing and Material standards. Coupled experimentation related to variations in compression ratio (CR) 17, 19, and 21 and fuel injection timing (IT) of 21°, 23°, and 25° before top dead center (bTDC) with load variations noted on diesel engines. We observed that, at full load, CR21 and 23° bTDC fuel IT, the brake thermal efficiency parameters rose significantly, whereas brake‐specific fuel consumption, and combusted flue gas temperatures also plummeted. The CO, HC, and smoke opacity emission for the B20 blend at CR21 and FIT23 has decreased by 30.52%, 33.33%, and 32.96%, respectively. At full load conditions, NOx emission for B20 biodiesel at CR21 was increased compared with the standard setting and compared with diesel it was increased by 6.46%.

“…It shows that by decreasing the value of speed and increasing the value of load, 0.25em Q i increases. This can be attributed to by as increasing the load on the engine means that it is working harder, which results in better combustion and more complete fuel utilisation (Atmanli et al, 2016; Chatur et al, 2023; Yilmaz et al, 2018). This leads to higher BTE and lower BSFC, which are desirable outcomes.…”

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.

“…Increasing the fuel inlet pressure does push the fuel further in the compressed air and thereby enhancing the fuel-air mixing process [31,32]. But by doing so, the fuel pump and injector need to be changed https://doi.org/10.17993/3ctecno.2023.v12n1e43.202-223 [31][32][33][34][35]. Also, denser fuels when injected at higher pressure show higher fuel combustion pockets thereby exhibiting, a higher amount of uncontrolled combustion activity [16,17].…”

Fuel Injection is a significant factor when biodiesel-diesel blends are fired in diesel engines as they have very diverse property when related to diesel. The current work describes unusual experimental study of CI engine fuelled with Waste cooking methyl ester with copper oxide nano additives at varying fuel injection pressures. The Copper oxide nano additives were manufactured using homogenous addition method and were subjected to studies such as XRD and SEM characterization. These synthesized nanoparticles were later added in waste cooking oil biodiesel blend (WCO20) with levels of 10 ppm, 20 ppm, 30 ppm, and 40ppm. The results were noted from a DI-CI VCR engine coupled with an eddy current dynamometer. The addition of CuO particles reduces the ignition delay of WCO20 and raises the thermal efficiency of the engine by an average of 3.9% and limits HC emission by 15.6%.
