Performances, Emissions and Soot Properties from a Diesel-Biodiesel- Ethanol Blend Fuelled Engine

Tse H, Leung CW and Cheung CS

The aim of this study is to provide experimental results for assessing diesel-biodiesel-ethanol (DBE) blended fuels as future technology for efficiently using these three fuels and for reducing engine emissions. The results included engine performance, brake specific emissions and soot properties for diesel-biodiesel blended with 0%, 5%, 10% and 20% ethanol tested at steady speed of 1800 rev/min under different engine loads. It was found that DBE blends can reduce NOx, CO2, volatile organic fractions and particulate mass-number concentration with improved thermal and combustion efficiency while slightly decreasing the particle size.
