“…The pressure that builds up in an engine’s cylinder during a power stroke is called “in-cylinder pressure.” This pressure equals the observed fuel burn rate for effort. The fuel–air mixture, ignition delay time, premixed combustion fuel burning, atomization, viscosity, evaporation and thermal energy also affected in-cylinder pressure (Gavaskar et al 2023 ; Musthafa et al 2023 ). Compared to the figure, complete fuel mixes and basic diesel fuel will have varied cylinder maximum cylinder pressure (MCP) and engine rpm.…”

This article presents the outcomes of a research study focused on optimizing the performance of soybean biofuel blends derived from soybean seeds specifically for urban medium-duty commercial vehicles. The study took into consideration elements such as production capacity, economics and assumed engine characteristics. For the purpose of predicting performance, combustion and emission characteristics, an artificial intelligence approach that has been trained using experimental data is used. At full load, the brake thermal efficiency (BTE) dropped as engine speed increased for biofuel and diesel fuel mixes, but brake-specific fuel consumption (BSFC) increased. The BSFC increased by 11.9% when diesel compared to using biofuel with diesel blends. The mixes cut both maximum cylinder pressure and $${{\text{NO}}}_{{\text{x}}}$$ NO x emissions. The biofuel-diesel fuel proved more successful, with maximum reduction of 9.8% and 22.2 at rpm, respectively. The biofuel and diesel blend significantly improved carbon dioxide ($${{\text{CO}}}_{2}$$ CO 2 ) and smoke emissions. The biofuel blends offer significant advantages by decreeing exhaust pollutants and enhancing engine performance. Graphical Abstract

Diesel engines may run on biodiesel, a sustainable fuel that can be made from a variety of feedstocks using various alcohols and catalysts. The type of alcohol has a direct impact on the biodiesel’s fuel qualities. Variations in fuel qualities can lead to variations in diesel engine performance, combustion, and injection characteristics. Using blends of 10%, 20%, 30%, and 40% with Karanja oil and regular diesel fuel separately, experimental tests were conducted to assess the performance and emissions of a direct injection, water-cooled Kirloskar diesel engine at 1500 rpm with variable load. The 3-hole and 5-hole fuel injectors are the subjects of this investigation. Because Karanja methyl esters (KME) have a lower calorific value than diesel, their value increases with the proportion of KME in the mix. For a 20% blend, this means that brake-specific fuel consumption increases. As the amount of KME in the gasoline increases, the brake thermal efficiency falls. At a 20% mix, Brake thermal efficiency is almost identical to diesel fuel. For all blends, CO and HC emissions rise with load and fall with the fraction of KME in the mix. For every combination of KME, the density of smoke rises as the load increases. Smoke density falls as the fraction of mixes containing KME rises. It has been observed that when nozzle holes are increased from three to five, brake thermal efficiency rises with load. When comparing a 5-hole to a 3-hole with load, the Brake-specific fuel consumption (BSFC) will fall. Nozzles have an influence on emissions in that as nozzle holes grow, so do CO, HC, and smoke opacity. According to the findings, a 20% KME blend for a 5-hole fuel injector nozzle is a good substitute for diesel.

“…The mixtures with the alcohol showed better brake efficiency, lower emissions with higher cylinder pressure and a peak heat release rate when tested in terms of engine characteristics. Musthafa et al [ 10 ] also discovered that the main advantage of adding alcohols (in particular ethanol, propanol and butanol) to fuels is the decrease in emissions. In this regard, the role of alcohol additives consists not only of improving the energy efficiency and engineering properties of fuels but also of making them more eco-friendly and less toxic.…”

This study addresses the pressing issues of energy production and consumption, in line with global sustainable development goals. Focusing on the potential of alcohols as “green” alternatives to traditional fossil fuels, especially in biofuel applications, we investigate the thermochemical properties of three alcohols (n-propanol, n-butanol, n-pentanol) blended with sunflower oil. The calorimetric analysis allows for the experimental determination of excess enthalpies in pseudo-binary mixtures at 303.15 K, revealing similarities in the trends of the curves (dependence on concentrations) but with different values for the excess enthalpies for each mixture. Despite the structural differences of the alcohols studied, the molar excess enthalpy values exhibit uniformity, suggesting consistent mixing behavior. The peak values of excess enthalpies for systems with sunflower oil and n-propanol, n-butanol and n-pentanol are, respectively, 3255.2 J/mole, 3297.4 J/mole and 3150.1 J/mole. Both the NRTL and Redlich–Kister equations show satisfactory agreement with the obtained values.
