PRACTICAL INVESTIGATION OF PERFORMANCE OF SINGLE CYLINDER COMPRESSION IGNITION ENGINE FUELED WITH DUEL FUEL

Abstract

This paper studies the performance of a single cylinder compression ignition engine Ricardo E6, fueled with different blends of ethanol added to diesel.The brake specific fuel consumption for dual fuel, in general, is higher than that for the diesel engine for low and medium loads; however, it becomes less than the diesel engine for high loads. The increase in the proportion of the ethanol in the mixture improves the specific fuel consumption at any specific load. The brake thermal efficiency for diesel engine is higher than that for dual fuel engine for low and medium loads, while it becomes lower for high loads. In general, the addition of ethanol in the mixture improves the efficiency. Retarding the injection timing of diesel fuel caused the specific fuel consumption to increase steadily to about 40% when the timing is too late. The thermal efficiency of dual fuel is lower, in general, than that of the diesel engine when retarding the injection timing.
