Performance and Emission Characteristics of Diesel Engine using Alternative Fuels

Najeeb Ullah Khan | Dr. M. M. Hasan

Abstract: The purpose of this study is to investigate the performance and emission characteristics of a diesel engine fuelled with diesel and its different blends with WCME biodiesel (15, 20, 25 %). The experiment was performed on single cylinder, four stroke VCR diesel engine at different loads and a speed of 1500 rpm. The compression ratio was kept 181. Exhaust gas emissions were measured by AVL gas analyzer. The parameters used to measure engine performance were SFC, BTE and emission characteristics were CO, CO2, HC and NOx. The results were compared among different biodiesel blends and also with pure diesel. The experimental results showed that the SFC of WCME biodiesel blends was higher than diesel. BTE of diesel was higher than biodiesel blends. CO and HC emissions decreases with addition of biodiesel blends in diesel. Diesel has lowest CO2 emission. NOx emission increases with addition of biodiesel.
