The fuel blends contained; Diesel mixed with Bio-diesel made from WFO in a ratio of 90-10% by volume; Diesel mixed with procured Bio-diesel in a ratio of 90-10 %; Diesel mixed with HGK in a ratio of 60-40% by volume and Diesel mixed with VO and HGK in a ratio of 50-10-40 % by volume. The experiments were performed in a four cylinder DI PIZZO diesel engine at six different engine-loading conditions (15N, 25N, 35N, 45N, 55N and 65N load). During experiments, the engine speed varied from 1450 rpm to 1700 rpm in steps of 50 rpm for each load condition. Several engine parameters i.e. power, brake specific fuel consumption, and brake thermal efficiency were investigated. As a complement of the experiment, the exhaust emission characteristic of CO and HC were also investigated. August - October 2014 Copyright © 2014 i-manager publications.
