Impact of Emulsion Fuels on Particulate Surface Morphology and Implications for Air Quality

Abstract

Emulsion fuels have emerged as promising alternatives for cleaner and more efficient combustion technologies. These fuels offer a sustainable pathway to reducing environmental impact through enhanced energy efficiency, improved torque, superior engine performance, and lower pollutant emissions. This study focuses on analyzing the surface morphology of particulates formed during the combustion of emulsion fuels to better understand the mechanisms underlying particulate matter (PM) formation in exhaust emissions. A multifaceted research approach was adopted, including the preparation of materials and experimental equipment, as well as the formulation of fuel blends, namely B5M10, B10M10, B5M10E3, and B10M10E3, where B represents biodiesel, M denotes methanol, E indicates an emulsion fuel, and the numbers correspond to blend ratios. The findings provide critical insights into how different fuel compositions influence particulate characteristics and emission behavior. The results support the viability of emulsion fuels and biodiesel as renewable, environmentally friendly alternatives capable of significantly reducing PM emissions, thereby contributing to improved air quality and sustainable energy solutions.
