Abstract
The purpose of this research work is to find the performance of bio -diesel fueled compression ignition engine with and without Zirconia ceramic powder as a thermal barrier coating on the piston head by using plasma spray technique. Experiments were carried out on water cooled engine at constant speed and fixed loaded compression ignition engine, to find the brake thermal efficiency, brake specific fuel consumption and brake power for various injection operating pressures and compression ratios. With an increased compression ratio from 13.99 to 17.5 the brake power, brake specific fuel consumption and brake thermal efficiency were found to improve by 2.55%, 20.75% and 9.23% respectively, similarly as injection operating pressure was increased from 160 to 190 bar the brake power, brake specific fuel consumption and brake thermal efficiency were found to be improved by 1%, 9% and 3.26% respectively.
