Abstract

This paper aims to study the effect of different fuel blends that were used to enhance combustion of main fuel in a diesel engine. Performance tests were conducted on a four stroke, single cylinder, 3.7 kW/5BHP diesel engine. Pilot fuel blends were directly introduced through a gravimetric fuel introduction system into the intake manifold of the engine. Based on the result obtained, it was found that, pilot fuel blends have resulted in enhanced combustion of diesel fuel. The pilot fuel blends 70 (DEE): 30 (Methyl Alcohol) and 50 (DEE): 50(Ethyl Alcohol) have shown significant increase in performance and hence can be used as effective combustion enhancers. Inferences drawn from the performance graphs shows and validate that using pilot fuel blends significantly improves the performance of the diesel engine.
