Comparison of Performance of Internal Combustion Engine Fuelled with Diesel and Biodiesel (used Vegetable Oil) Blends

Abstract

Due to the rising mechanical requirements, the cost of customary powers is becoming more expensive. Rough oil use contributes to increasing environmental pollution; hence it is necessary to look into alternative fuel sources with little to no environmental impact before using them for vehicles and other purposes. The combustion characteristics and thermal performance of the diesel fuel-burned internal combustion engine (DICE) were explored in this paper after employing biodiesel (containing a blend of used vegetable oil and diesel) in steady-state operation using vegetable oil utilised as biodiesel. They were mixed with diesel fuel in varying used vegetable oil concentrations of 5 %, 10 %, 15%, and 20 %, respectively. The DICE utilised in this study was a single-cylinder, four-stroke, water-cooled diesel engine. The analysis revealed that biodiesel blends (UBF20) showed 49% higher indicated power than diesel at 1498 rpm. Generated torque of biodiesel blends (UBF5, UBF10, UBF15, and UBF20) was nearly similar to that of diesel at different loads and speeds.
