Combustion and Emission Characteristics of Diesel Engines Using Diesel, DMF/Diesel, and N-Pentanol/Diesel Fuel Blends
Publication: Journal of Energy Engineering
Volume 144, Issue 3
Abstract
In recent years, researchers around the world have focused on biofuels such as 2,5-dimethylfuran (DMF) and n-pentanol because of their potential for reducing harmful emissions. Studies show that oxygenated biofuels can decrease soot emissions from the exhaust gas recirculation (EGR) engine. This study compared the combustion and emission characteristics of diesel, D20, and P20 fuels on HD diesel engines without EGR. Results show that D20 and P20 fuels show no obvious advantage in emissions compared with diesel fuel. For some load conditions, D20 and P20 have relatively better fuel economy, but overall fuel economy has little difference for the three fuels. Although D20 and P20 can be used without any engine modifications, the performance and emission characteristics of P20 fuel are closer to those of diesel fuel than to D20 fuel. These results can be used in the development of alternative bio-fuels for use in the auto industry.
