Compression ignition engines are ubiquitous and quite popular in the automobile industry today. Many vehicles used today run on compression ignition engines. Considering the significant market presence of CI engines, this experiment aims to looks to investigate and possibly improve the effect a certain fuel blend has on CI engine parameters. In particular, the endeavor of this project is to study the effect on various loading conditions of a CI engine running on palm oil blended (D90A10, D60A40, D80A20, D70A30, D50A50, D40A60) with conventional diesel. The comparative measurements of CO2 and NOX have been stated and analyzed, along with BSFC and brake power. The results showed that blend of biodiesel D90A10 showed average increase in brake power than diesel.
