Assessment of the effects of microwave‐produced biodiesel blends on electric generator performance and emissions

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Biodiesels are emerging as alternatives to diesel fuel. However, to be a feasible solution, biodiesels must meet strict criteria including high efficiency and minimal environmental impact. The current study focuses on evaluating ethyl ester biodiesel and its blends with diesel fuel to assess their potential.

Effects of hybrid metal oxide nanoparticles on the tribological and emission attributes of algae‐derived biofuel in compression ignition engines

Environmental Progress &Sustainable Energy, EarlyView.
Abstract The growing demand for sustainable fuels has accelerated the development of algae‐derived biodiesel for compression‐ignition engines. In this study, Chlorella vulgaris methyl ester (AME) exhibited physicochemical properties comparable to diesel and satisfied ASTM D6751 fuel quality requirements, making it suitable for blending.

Multi‐Objective RSM Optimization of Emission and Performance Characteristics in a Diesel Engine Fueled With BaTiO3 Nano‐Enhanced Jojoba Biodiesel

Energy Science &Engineering, EarlyView.
This study uses response surface methodology to optimize Jojoba biodiesel blended with BaTiO3 nanoparticles in a single‐cylinder diesel engine. Results show that ~48.95–51.31 ppm of BaTiO3 achieves balanced performance and emission, decreasing CO and NOx while increasing torque and brake thermal efficiency.
