Exergy and Energy Analysis of α-Fe2O3-Doped Al2O3 Nanocatalyst-Based Biodiesel Blends-Performance and Emission Characteristics

A. Anderson et al.

Summary: The study focuses on the engine performance and emission characteristics of rapeseed and soya biodiesel dispersion on a novel nanocatalyst at different concentrations, showing that the incorporation of nanoparticles in biodiesel enhances performance by reducing the content of lignin and unsaturated fatty acids. Emissions of NOx, hydrocarbon and carbon monoxide increased significantly with higher nanoparticle concentrations, while the addition of nanoparticles reduced CO emissions and improved engine performance in soya seed biodiesel blends with 50 ppm nanoparticles compared to other blends.

Experimental assessment of performance, combustion and emission characteristics of diesel engine fuelled by combined non-edible blends with nanoparticles

Abdulaziz A. Al-Kheraif et al.

Summary: This study focuses on utilizing Candle nut and Soap nut biodiesel as an alternative to conventional fuel, incorporating nanoalumina at a concentration of 25 ppm to analyze emission characteristics and engine performance. The results show that the nanoparticles improve engine performance significantly due to the increased surface area to volume ratio of Al2O3, leading to reductions in nitrous oxide, carbon monoxide, and hydrocarbon emissions at higher concentrations. Among the various biodiesel blends, 30B samples demonstrate the best results in reducing emissions.
