“…The smoke emission is an important factor in evaluating a biofuel blend, and using S biofuel in the diesel engine with diesel fuel has greatly reduced smoke emission, improving combustion kinetics (Afzal et al 2023 ). The current study shows a significant reduction in smoke emissions compared to Santhosh et al, who found that adding diesel, biodiesel and ethanol to diesel fuel increases emissions and decreases CI engine performance (Effendy et al 2021 ).…”

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

“…Instead of using an empirical calculation, the artificial neural network model learns from a large amount of input and output data. Remember that the activation function decides what the result is (Afzal et al 2023 ; Elumalai et al 2022 ; Veza et al 2022 ). The input value and the cut off value are both shown in the functions output.…”

“…Non-renewable energy sources, such as fossil fuels, are rapidly depleting, necessitating a transition to renewable energy sources for the benefit of humanity [1,2]. The depletion of fossil fuel resources, rising environmental pollution, and fluctuating fuel prices have motivated the adoption of biofuels such as biodiesel and bio-alcohol as promising renewable energy sources [3,4]. These fuels are considered clean, inexpensive, and abundant [5,6].…”

The global automotive industry is facing significant challenges, including dwindling fossil fuel reserves, rising crude oil prices, and increasingly strict emission regulations. To address these concerns, this study investigates the impact of the compression ratio (CR) and exhaust gas recirculation (EGR) on the performance and emissions of a common rail direct injection (CRDI) diesel engine fuelled with a 20% blend of tamarind seed methyl ester (TSME 20) biodiesel. The study employed an open-type electronic control unit to implement pilot fuel injection at a rate of 30%, 23° before the top dead centre (TDC), and at a higher pressure of 600 bar. Three CRs (16:1, 18:1, 20:1) and two types of EGR (hot and cold EGR at 10%) were evaluated. Diesel fuel at CR 18 was used as a baseline for comparison. The experimental procedure involved conducting tests with TSME 20 at CR 16, 18, and 20. Subsequently, TSME 20 at CR 20 + Hot EGR 10% and TSME 20 at CR 20 + Cold EGR 10% were examined. The results showed that TSME 20 operated at a higher CR (CR 20) exhibited improved diesel engine performance and significant reductions in harmful exhaust emissions. Additionally, cold EGR at 10% was more effective in reducing CO, CO2, and NOx emissions from TSME 20 than hot EGR. The findings of this study provide valuable insights into optimizing diesel engine operation to achieve a balance between performance enhancement and emission reduction through tamarind seed biodiesel blends and different EGR techniques. The implementation of these strategies holds considerable potential in addressing the automotive industry’s challenges, including ecological considerations and fuel price fluctuations.

“…Being one of the potential alternative fuel sources, biodiesel is often regarded as the most viable renewable fuel, owing to its biodegradable, ecologically benign, and toxic-free properties. − However, biodiesel has a few drawbacks over petro-diesel, in which a significant impediment is the high cost of feedstock that could account for 75–88% of overall manufacturing expenses . Due to this reason, discovering alternative raw materials for biodiesel synthesis that do not compete with food sources is crucial, necessitating a shift away from traditional vegetable oils or animal fat. , The fact shows that biodiesel could be produced from an extensive range of raw sources like fatty acids, animal fats, waste oils, microalgae, or vegetable oils. − However, the food-energy debate has been addressed in poorer nations concerning edible oils. Low-quality oil with a high free fatty acid (FFA) level is expected to be utilized as a feasible feedstock to boost biodiesel’s competitiveness pricing. , Low-quality oils, such as waste oils, animal fats, and nonedible crop oils, have higher FFA and water content, which may impair biodiesel output and quality owing to adverse reactions.…”

The rapid depletion of fossil-derived fuels along with rising environmental pollution have motivated academics and manufacturers to pursue more environmentally friendly and sustainable energy options in today's globe. Biodiesel has developed as an ecologically favorable alternative. However, the mass manufacturing of biodiesel on an industrial scale confronts substantial cost and pricing challenges. To address this issue, highefficiency catalysts with a large number of active sites are needed, resulting in increased biodiesel output and quality. Metal−organic frameworks (MOFs) have received a lot of interest as a catalyst for converting oils/fats or fatty acids into biodiesel. MOFs are polyporous materials that can alter pore size as well as topological structure. They serve as a versatile foundation for designing active sites to satisfy the unique needs of catalytic reactions and conversion pathways. The purpose of this current work is to shed light on the underlying mechanisms and essential properties of MOF-based catalysts used in biodiesel synthesis. In addition, several methods for connecting active sites inside MOFs are scrutinized, while the properties and usability of MOF-based catalysts for the biodiesel production process are completely compared to other catalysts. More importantly, limits and future research directions about the utilization of MOFs in the biodiesel synthesis route are also critically presented. In general, this review contributes to improved awareness about the potential of MOFs in the biodiesel production sector by investigating the primary mechanism and characteristics of MOF-based catalysts.
