“…But still, when the properties of pure esters are compared to conventional diesel fuel they factor out the possibility to be used as an alternative fuel to diesel engines [11,12]. To address this issue, Esterified oils or Biodiesel are blended with diesel fuel and by doing so, the properties of the Esterified oil-diesel blend have in-line fuel properties [13,14]. When these blends are combusted in regular diesel engines, the thermal performance is good and emissions like CO and HC are limited [15,16,[1][2][3].…”

“…Also, denser fuels when injected at higher pressure show higher fuel combustion pockets thereby exhibiting, a higher amount of uncontrolled combustion activity [16,17]. In recent years, a lot of work is done to challenge this malfunction and one of the ways seems to be the use of nano metal oxides [13][14][15]. Nano metal oxides have a higher surface area than volume ratio, which tends to absorb the heat of combustion and retard the ignition delay of fuel [12].…”

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%.

“…Campli et al 27 presented at the effect of nickel oxide nano-additives in Azadirachta indica biodiesel-diesel blend on engine performance and emission characteristics by varying compression ratio. Srinidhi et al 28 Therefore, the current research is trying to explain how to use biofuel optimally in the power generation process cycle in combined power generation systems for Iran in a way where all the effective elements such as reducing greenhouse gas emissions by applying social costs and determining the permissible limit of their emission as well as creating a sustainable electric energy supply chain in comparison with fossil fuel-based systems should be investigated and technical, financial and environmental evaluation tables for each of the models to provide a clear picture for decision-making based on the economic justification of choosing the optimal plan should be presented. For this purpose, the case study strategy was used in the research.…”

Today, using systems based on renewable resources is a suitable alternative to fossil fuels. However, due to problems such as the lack of access in all the times needed to supply cargo and high‐investment cost, it has not been well‐received. In this research, in addition to maintaining the technical specifications and increasing the reliability of the system due to the addition of the hydroelectric power plant to other wind and solar systems, it has been tried to use biodiesel fuel (biofuel) as an alternative to fossil fuel in the diesel generator. To identify the most economical combination of the system with the application of social costs and the limit of pollutant and greenhouse gas emission in independent mode with the help of Homer software. the results showed that adding biodiesel to the designed system, the investment costs will increase by $282,038, which has a direct impact on the cost of energy and causes an increase of 0.0115 $/kWh. While the use of biodiesel reduces the emission of carbon dioxide by 28,947 kg/year.

“…Based on various biodiesel–diesel (BDD) blend thermophysical properties, the BDD is a heavier and thicker fuel, which will require more time for combustion and higher fuel injection pressure also. Varying fuel injection timing plays a pulsating role as most researchers have found that advancement in fuel injection leads to higher NOx emissions and a slight rise in fuel economy 5,6 . On the contrary, higher fuel injection does lead to better fuel atomization and does result in higher combustion pressure and temperatures, thereby NOx levels are high in emission.…”

The current exploration of alternative fuels to conventional engines is tested on two fronts: the thermophysical property assessment and the other, real-time evaluation using engine testing using the fuel. The engine testing fueled with modified oils/esterified blends does give real-time analysis but at the cost of harmful emissions dumped into the polluted environment. The current work describes the use of possible simulations and the validity of simulation confirmed from real-time experimentation at varying engine compression ratios (CRs). Engine parameters were kept the same for simulations that were performed on the Diesel RK module and experimental analysis.Neem oil blends were prepared and tested for the composition of FFA and later the required properties were supplemented to software for possible thermal performance and emission detections. The thermal efficiency deviation observed between RK model and experimental values for CR 18 for Diesel, B20, B40, and Heat Transfer. 2022;51:7990-8004. wileyonlinelibrary.com/journal/htj B100 was 5.8%, 1.9%, 3.4%, and 2.1%, respectively, and for NOx, the deviation observed for Diesel, B20, B40, and B100 was 8.9% and 13.7%, 12.2% and 14.1%, and 9.4% and 11.1%, respectively. The peak HRR and cylinder pressures observed for software simulations and real-time experimental approaches did not vary much, but the peak values do differ by 6.7% and 4.7%, respectively.
