The main aim of these work is to investigate the effect butanol blending at various EGR and VCR at full load condition, On the emission and performance characteristics the testing results are compared with the pure diesel and rapeseed oil methyl ester (B100). The rapeseed oil methyl ester-butanol blend were 20% butanol by volume basis at EGR rate 0%, 5%, 10%, 15% and VCR 14, 16, 18. The blending result shows that the viscosity and density is decreased and close to the diesel fuel. As compared to biodiesel the butanol blending fuels are showing less nitrogen oxide(NOx) Emission. On the other hand high carbon monoxide(CO) and unburned hydrocarbon emissions. The 20% butanol is a highest concentration of blend in biodiesel causes higher CO and HC emission and lower the NOx emission than biodiesel. The EGR achieves lower NOx as the percentage of EGR is increased. The performance diesel engine increases with the increase in compression ratio.
