Performance and Emission Characteristics of Dual Fuel CI Engine

Abstract

The present concern on energy demands, cause a growing interest on different fuels, for a sustainable solution, typical engines befittingly changed and experimented for favorable results. This context the present work dealt a newer approach as LPG as primary fuel and diesel DEE as pilot fuel. LPG gas presents a very promising alternative to diesel oil since they are having similar properties. The LPG has a low cetane number, therefore DEE added to the LPG to enhance cetane number. With the cetane improver, stable Diesel engine operation over a good range of the engine loads was possible. In this work, we studied the emissions of Diesel-LPG-DEE blends at completely different mixture and different loads. Experimental result showed that the thermal potency of LPG powered Diesel engine was equivalent to Diesel fuel operation. Exhaust emissions measurements showed that NOX and smoke could be significantly reduced with the blend of LPG, and DEE.
