Performance and Emissions Characteristics of VCR Engine Fueled with Mixed Biodiesel Blends

Abstract

In recent years, research on alternative fuel which is an environmental friendly in nature has been carried out thoroughly by many researchers through their enormous experimental work. An experimental study was performed on VCR engine using neat diesel and mixture of JME and SME biodiesel-diesel blends. The performances of biofuels attained from the binary biodiesel and its different proportions with full load condition of the engine are analyzed in this paper with few fuel properties. The experimental work is conducted for different load conditions (No load, 30%, 60% and 90% at constant speed (1500 rpm). Engine performance (BSFC, BTE) and emissions (Hydrocarbon, CO & NOx) is measured to find out the nature of the engine running condition with two mixed biofuels. According to the results indicate the two mixed biodiesel Blend A (Diesel 80%, SME10% and JME 10% by vol ); Blend B (Diesel 60%, SME20% and JME 20% by vol) is a appropriate alternative fuel for pure diesel and minimized air pollution in the atmosphere.
