COMPARISON OF THE PERFORMANCE AND EMISSIONS OF DIFFERENT BIODIESEL BLENDS AGAINST PETROLEUM DIESEL

Abstract

Biodiesel, a petroleum diesel replacement, is utilised to lower emissions without changing engines. Using an internal combustion engine (Kubota V3300) and ISO 8178 criteria, this research compares the performance and emissions of various biodiesel mixes with petroleum diesel. This research examined two forms of biodiesel: type A (80% tallow/20% canola oil methyl ester) and type B (80% chicken tallow/30% waste cooking oil methyl ester). The performance (primarily torque and braking power) of both biodiesel fuels decreases with increasing mix ratio, perhaps due to biodiesel's reduced energy content. As predicted, both biodiesels have higher specific fuel consumption than diesel. Some of the emissions were greater than petroleum diesel, while others were lower. Overall, Biodiesel A has fewer emissions than diesel and Biodiesel B.
