Experimental Investigation on the Performance, Emission and Combustion Characteristics of a Diesel Engine Fuelled with Polymer Oil - Ethanol Blends

Abstract

This paper describes an experimental study of using polymer oil obtained from the plastic waste as a fuel in diesel engine. In this study, the effects of using polymer oil – ethanol fuel blends [PE10, PE20] on the engine performance, exhaust emissions and combustion characteristics have been experimentally investigated. In the present work, 10% ethanol and 90% polymer oil, called here as PE10 and 20% Ethanol and 80% polymer oil called here as PE20 were used in a single cylinder four stroke, water cooled diesel engine. The engine fuelled by the blends is comparable with that fuelled by diesel. The experimental result showed that the carbon monoxide, carbondioxide, Oxides of nitrogen and smoke were significantly reduced.  Unburned hydrocarbon, brake specific fuel consumption and brake thermal efficiency were found to have increased with ethanol-polymer oil blends.
