Experimental investigation on diesel engine through n-Butanol blend biodiesel

Abstract

N-Butanol may be considered as the future replacement to ethanol due to its lower latent heat of vaporization, low level of impurities and higher heating value than diesel. These properties motivated researchers to perform the experiments in this field in the search of alternative fuels. In the current work an experimental investigation on single-cylinder four stroke diesel engine charged up with n–Butanol blends and pure diesel were used to predict the performance parameter without modification in the engine. In this experimental investigation, N-Butanol was added to diesel with known percentages to enhance the performance of a diesel engine. The blends of n- Butanol biodiesel and diesel fuel were mixed as in the percentage of 95% diesel with 5% n-Butanol as B5, 90% diesel with 10% n-Butanol as B10, 85% diesel with 15% n-Butanol as B15 and 80% diesel with 20% n-Butanol as B20 respectively. Results showed that when the percentage of the blend of n-butanol blend increased to 20% at 16 kg load then Brake thermal efficiency were increased to 30.33% and Brake specific fuel consumption were deceased 16.7% at 16 kg load simultaneously. The results of the experimental study can be further utilized to carry out a similar investigation with various blends of Biodiesel.
