Abstract:
Biodiesel has been gaining increased attention from engine researchers in view of the energy crisis and increasing environmental problems. The present work is aimed at experimental investigation of exhaust emission characteristics of ethanol – diesel blends tested in four stroke CI engine. The Diesel Engine Test Bed (Petter: PJ2W-type, 7227/22.5 BS) was used with varying percentages by volume of ED blends having 5, 10, 15, 20% ethanol and 95, 90, 85, 80% diesel respectively. The effect of the blends on exhaust emissions was studied. It was found that at all loads conditions, carbon dioxide emissions increased, while hydrocarbon emissions decreased with increased amount of ethanol in the fuel blends, with ED20 showing the least emissions levels. Also, at all loads conditions, NOX emission of the blends was found to be higher than that of standard diesel due to the oxygen concentration and combustion timing. The results found showed that the ED20 (20% ethanol and 80% diesel) can be used in CI engine without any modification.
