Investigated kerosene-diesel fuel performance in internal combustion engine

Abstract

This work aims to identify the impact of blending diesel fuel with kerosene on the engine performance and fuel consumption. In addition, this work aims to find the optimum blending ratio that would not notably drawback the engine performance. Blended diesel fuel with kerosene in volume percentages between 7 and 20% was investigated in a four-strokes, single-cylinder, and internal combustion engine to evaluate the engine performance and fuel efficiency at three torques (2, 4, and 6 N m) and constant speed (2000 rpm). The study involved determining several operational parameters, which are the brake-specific fuel consumption (BSFC Kg/kW.h), brake-specific energy consumption (BSEC MJ/kW.h), brake thermal efficiency (BTE), engine effective power (Ne kW), and the noise intensity (measured in dB). The results show that small volume percentages (up to 14%) do not significantly lower the engine performance and fuel consumption. Specifically, the losing in BSFC from blending ratios of 7% and 14% are only 3.8% and 9.6%, respectively. The blending of diesel fuel with kerosene can help minimizing the pollutant emission and decrease the engine noise intensity. Thus, this work concluded that diesel fuel could be blended with kerosene up to 14% without significantly reducing engine performance and fuel efficiency.
