With the continuous growth of global energy demand and increasingly prominent environmental issues, research utilization renewable as a substitute for traditional fossil fuels have gained significant importance. Biofuels, recognized key source, are widely considered viable alternative to fuels. The primary component biodiesel is fatty acid methyl esters (FAMEs), which prone oxidative degradation due their unsaturated nature during storage transportation. Various studies identified several factors influencing stability biodiesel, including oxygen, temperature, light, water content, microbial growth, corrosion metal tanks. This article provides comprehensive summary effects different on explores interrelationships between these factors. To enhance strategies been proposed, such optimizing production processes, adding antioxidants, controlling environments, conducting regular inspections. review aims provide theoretical basis long-term promote its widespread application in practical scenarios.

This research explores the performance, exhaust emissions, and combustion properties of a Premixed Charged Compression Ignition (PCCI) engine using combinations Andropogon narudus (AN) Sapota Oil Methyl Ester (SOME) blended as substitute fuels. A split-fuel injection system was used, supplying 70% fuel with direct 30% through intake air manifold. The test fuels considered were D100 (commercial diesel), AN20 + D80, SOME20 their corresponding mixture nano-additives CeO₂ Al₂O₃ (10 ppm).Performance analysis showed that highest brake thermal efficiency (BTE) attained by D80 Al₂O₃, which rose 2.5% respect to diesel, 2.3% rise in BTE. Brake-specific consumption (BSFC) reduced 0.10 g/kWh for diesel due its lower viscosity. Emission hydrocarbon (HC) emission decrease up 7 ppm all blends tested, although CO₂ NOx emissions higher AN SOME nano-additives. Combustion studies revealed had maximum peak pressure net heat release rate, supports effect on behavior. For improving predictive accuracy, machine learning-augmented modeling utilized Multiple Linear Regression (MLR), Random Forest (RF), Support Vector Machine (SVMR). RF model performed better efficiency, giving R² = 0.97 NOx, 0.99 Smoke, 0.95 CO, capturing nonlinear relationships well. MLR good fits BTE (R² 0.99) BSFC 0.94), whereas SVMR poorer predictions (e.g., Smoke: 0.19, CO₂: 0.30).A sustainability ranking situated at most viable biofuel position, particularly addition Al₂O₃. Predictive analytics derived from ML study focus role achieving maximal alternative mixtures, less reliance huge experimental trials, more cleaner efficient burning systems.
