Impact of Oxygenated Fuels on Dry Soot Emissions in Diesel Engines

Abstract

Dry Soot emissions pose a significant challenge for diesel engines, as they can severely impact human health and the environment. This study investigates the impact of oxygenated fuels on Dry Soot emissions from a TF120 YANMAR direct injection compression ignition diesel engine. Tests were conducted at engine speeds ranging from 1200 to 2400 rpm under no load, 50% of load, and 100% of load conditions. Diesel fuel was used as a comparison between two types of biodiesel blend fuels and two types of water-in-biodiesel blend fuels. The biodiesel blends included 5% biodiesel with 10% methanol (B5M10) and 10% biodiesel with 10% methanol (B10M10). The water-in-biodiesel blends included 3% water in the B5M10 blend (B5M10E3) and 3% water in the B10M10 blend (B10M10E3). The results indicate that the water-in-biodiesel blend fuel produced lower dry soot emissions than biodiesel blends and conventional diesel, highlighting their potential as environmentally friendly fuel alternatives.
