Experimental Investigation on Performance and Emission Analysis of a Modified CI Engine Using Tobacco Seed and Cotton Seed Methyl Ester Blends

Abstract

Present study explores the emission and performance characteristics of a conventional and modified i.e., adiabatic (LHR) CI engine with biofuels derived from tobacco seed and cotton seed methyl esters. The primary objective is to assess the viability of these biofuel blends as sustainable alternatives to conventional fuel, focusing on their effects on engine performance parameters such as BTE, SFC and BP output, as well as on key emission factors including carbon CO, HC, ???????????? and Smoke opacity. The conventional and modified CI engine was examined with CSOME, TSOME and TCOME. The results demonstrate that the conventional CI engine with TCOME enhanced brake thermal efficiency and highest value is 25.65% at 80% load which is 80% and 37.3% higher compare to TSOME and CSOME, with substantial reductions in CO, HC, ???????????? and smoke opacity emissions and for LHR engine configuration showed improved BTE by 8.8% and CO, HC, Smoke opacity and ???????????? reduced by 5.9%, 4.9%, 15% and 11% at 80% load compare to conventional engine with TCOME. Overall, the study indicates that tobacco seed and cotton seed methyl ester blends offer a promising alternative with LHR CI engines, contributing to improved performance and a reduced environmental footprint.
