An Empirical Investigation of Biodiesel Engine Fuelled with Palm Oil Methyl Ester Biodiesel Blends
Main Article Content
Abstract
Compression ignition, single zone biodiesel engine model has been established based on engine geometries (stroke, cylinder diameter, connecting rod length and diameter of crank). Deviation in specific heat ratio of engine cylinder charge and burned gases has been established to anticipate the pressure fluctuation relative to the crank angle, engine output and mean effective pressure relevant for Palm Oil Methyl Ester (POME) biodiesel. Predicted model for biodiesel engine has been verified using diesel and POME blended biodiesel (B5 and B10). In order to find out the performance results and combustion nature, constant engine speed (1500 rpm) is maintained during the experiments under 0%, 25%, 50% and 100% loading. It has been observed that when the experimental engine setup was fuelled with POME B10, the performance is depleted for loading other than 50% to 75% load condition and combustion aspect of B5 and B10 POME is slightly changed in comparison with diesel.
