A Novel Investigative trade-off Analysis of various Undi Methyl Ester blends with n-butanol Additive in a Prechamber Engine at Varying Loads

Abstract

This study exhibits the experimental result of different bio diesel blends with additive(butanol) in a CI engine at varying loads from 25% to 100%.The bio diesel used in this work was Undi bio diesel which was blended in various ratios with butanol additive and diesel. From the results it was found that the bio diesel butanol blends showed better CO,UHC results compared to diesel. But <em>bsfc</em> was higher and BThE was lower for the blends. On the other hand the bio diesel and diesel blends resulted higher CO, UHC and NO_x emissions. But D50U50 showed better <em>bsfc</em> and BThE results than diesel. The significant finding from the experimental work was the NO_x emission was reduced by the bio diesel diesel butanol blends. Trade-off analysis of <em>bsfc</em>, Equivalence Ratio and NO_X was evaluated where the butanol blends showed better emission results at higher cost of <em>bsfc</em> and BThE.
