“…Using oxygenated soybean enhances fuel properties, resulting in decreased residence time and reduces delay duration. Soybean biofuel helps produce a lower adiabatic flam temperature, minimizes temperature rise in the surrounding area and promotes low-temperature combustion (Mirhashemi and Sadrnia 2020 ; Kalyani et al 2023 ; Masera and Hossain 2023 ). As a consequence of this, the additive in the D80S20 mix demonstrates significantly reduced levels of emissions.…”

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

“…Moreover, the emissions from the engine running on ABD40 with 4% triacetin were significantly lower than those from pure diesel fuel. Specifically, there was a reduction of 25.51% in CO emissions, 12.81% in NOx emissions, 70.53% in unburned hydrocarbons, and 14.85% in smoke emissions at 100% load compared to diesel [66]. Researchers examined the use of algae biodiesel blended with methanol in three different proportions: B10 (10% diesel + 90% algae oil + 2.5% methanol), B20 (20% diesel + 80% algae oil + 5% methanol), and B30 (30% diesel + 70% algae oil + 7.5% methanol).…”

“…An oxygenated additive called triacetin is used with a blend of spirogyra algae oil biodiesel and diesel fuel (ABD40) to investigate its impact on combustion, engine performance, and exhaust emissions in a single-cylinder 3.5 kW diesel engine [66]. Researchers tested different concentrations of triacetin (2%, 4%, 6%, and 8% by volume) mixed with ABD40 while maintaining a constant engine speed and varying engine loads.…”

The production and utilization of biodiesel derived from microalgae have gained significant attention as a sustainable alternative to fossil fuels. However, the intrinsic properties of microalgae biodiesel can limit its performance and lead to undesirable emissions. This paper summarizes the impact of additives on microalgae biodiesel, focusing on their influence on performance and emissions. Additives play a crucial role in improving the overall quality and efficiency of microalgae biodiesel. They encompass a range of compounds, including antioxidants, stabilizers, and combustion enhancers. These additives have been studied extensively to elucidate their effects on fuel properties, engine performance, and exhaust emissions. By modifying the physicochemical properties of microalgae biodiesel, additives can enhance its stability, cetane number, and oxidative resistance, thereby promoting efficient combustion and reducing emissions of harmful pollutants. This review concludes that the usage of additives to the algae biodiesel leads to improved combustion performance and emission reduction.

Biodiesel produced from different edible and non‐edible feedstocks is a viable alternative option for fueling a combustion engine. However, the widespread use of edible sources for biodiesel production may lead to food versus fuel controversy. Oil from non‐edible feedstock is best possible solution for problems that inhibits biodiesel production on commercial scale. This study presents the potential of different non‐edible feedstock for biodiesel production. Several aspects such as extraction technologies used for extracting oil from non‐edible sources and biodiesel production pathways from non‐edible feedstocks are discussed. The quality of biodiesel should be assured before its commercialization by different physical and chemical characterization techniques are used. In particular, the emission comparison of biodiesel derived from the different non‐edible feedstocks is discussed. Based on this study, the non‐edible feedstocks have the potential to produce biodiesel but still it has a long way to go. This is due to non‐edible feedstock is in the R&D phase and needs more research to eliminate additional treatment steps compared to edible feedstock for economic aspects. Furthermore, there has been a trade off in emission properties of biodiesels produced from non‐edible feedstocks which must be removed or evaluated for pilot scale investigations before commercialization.
