Evaluation of a Novel Biofuel Blend using Diesel-Biodiesel-Ethanol on Light Commercial Vehicle

Investigation on the combustion characteristics and particulate emissions from a diesel engine fueled with diesel-biodiesel-ethanol blends

“…They are also effective in reducing BSPM emissions, compared with ULSD, due to the increasing displacement of diesel fuel by ethanol which has higher oxygen content and lower fuel aromatics and fuel sulfur, all of which are favorable for reducing soot formation. The results are similar to the findings reported by Muralidaharan et al [18] in their study of DBE blends on light commercial vehicle.…”

“…Their study involved a DBE blend with 80% diesel-15% biodiesel-5% ethanol and they found that the DBE blend was much more effective in reducing particle number and particle mass when compared with B20 (80% diesel-20% biodiesel). Muralidharan et al [18] also investigated DBE blends with 5% ethanol. They concluded that the particle size and number reduced with DBE blends.…”

“…As such, DBE (diesel-biodiesel-ethanol) blended fuel has been studied in recent years so that the disadvantages of either diesel-biodiesel or diesel-ethanol blended fuels can be overcome [13e17]. For example lubricity and cetane number of diesel fuel will be degraded by ethanol due to its lower density and viscosity while biodiesel has good lubricity and high cetane number which could enhance the lubricity and cetane number of diesel-ethanol blends [14,18]. Investigations on DBE for diesel engines can be traced back to as early as 1995.…”

Performance and Emission Analysis of Diesel Engine Using Oxygenated compounds

“…Smoke or particulate matter emissions are mainly due to the lack of oxygen during the combustion process. [1,2,8] In addition to that a slight increase of bsfc is observed due to the slight decrease of fuel heating value with the increase of the oxygen content Brake thermal efficiency increased when the oxygen content was increased. [4]When taking into consideration the production potential of bio-diesel brake specific fuel consumption and NO x emissions the ratio of the biodiesel in the bio-diesel-diesel fuel blend should be kept at low ratio.…”

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

“…Biodiesel can be used as an additive in preventing the separation of ethanol from diesel. As such, diesel-biodiesel-ethanol (DBE) blended fuel has been investigated in recent years so that the disadvantages of either diesel-biodiesel or diesel-ethanol blended fuels can be overcome while maintaining the engine performance close to standard diesel with reduced emissions [1,4]. Shi et al [5] studied the emission characteristics of DBE (75% diesel, 20% methyl soyate and 5% ethanol) on a Cummins-4B diesel engine and found a significant reduction in PM emissions and 2-14% increase of NOx emissions.…”
