“…There is an explosive increase in the concentration of active reaction centers associated with the decay of intermediates and intensive branching of chains. Shortly after ignition, the concentration of active centers and the rate of combustion reach a maximum, after which they also decrease sharply due to the burnout of fuel vapors formed during the period φi [12][13][14][15][16].…”

Modeling of in-cylinder processes occurring in a dual-fuel engine is necessary to obtain the ignition delay period as a function of the angle of rotation of the crankshaft and the subsequent calculation of its effective and environmental indicators. There is a need to identify the theoretical dependence of the fuel combustion process on the parameters that determine the operating modes of a dual-fuel engine, which leads to the need to create a mathematical model that allows the most accurate description of the combustion process, taking into account the maximum possible number of factors. The paper considers the optimization of the parameters of the workflow and the prediction of the performance of the projected and existing dual-fuel engines.

“…CO emissions are created by the incomplete oxidation of carbon atoms in the combustion chamber's rich mixture sections at temperatures less than 1180°C (Deheri et al, 2020;Sarıdemir et al, 2024). In a study by Zhang et al (Zhang et al, 2022) it was reported that hydrogen incorporated with nanoparticles results in a decrease in CO levels. Because the quantity of biofuel utilized raises the oxygen concentration, this is the case.…”

As a sustainable replacement for fossil fuels, biodiesel is a game-changer in the energy sector. There is no strategy to minimize biodiesel's significance as a sustainable, clean fuel source in light of the increasing climate change and environmental sustainability concerns. Nevertheless, conventional biodiesel production methods often run into problems like inadequate conversion efficiency and inappropriate fuel properties, which impede their broad adoption. The revolutionary potential of nanotechnology to circumvent these limitations and revolutionize biodiesel consumption and production is explored in this review paper. There are new possibilities for improving biodiesel output and engine efficiency, thanks to nanotechnology, which can alter matter at the atomic and molecular levels. Using nano-catalysts, nano-emulsification processes, and nano-encapsulation procedures, researchers have made significant advances in improving biodiesel qualities such as stability, combustion efficiency, and viscosity. Through a comprehensive analysis of current literature and research data, this article elucidates the crucial role of nanotechnology in advancing biodiesel technology. By shedding light on the most current advancements, challenges, and potential future outcomes in nano-based biodiesel manufacturing and consumption, this review hopes to add to the growing corpus of knowledge in the field and inspire additional innovation. In conclusion, there is great hope for a sustainable energy future, increased economic growth, and reduced environmental impacts through the application of nanotechnology.

“…For instance, while the fuel consumption related to brakes was reduced, the power, torque, and thermal efficiency of the brakes all improved. While the major goal of lowering CO, CO2 and other UHC emission was achieved, the NO emission increased marginally [87][88][89][90].…”

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%.
