Abstract: Paper A comparative experimental analysis was carried out on a 4-stroke single cylinder, vertical, water cooled, Compression Ignition engine with combustion chamber coated with Yttria Stabilized Zirconia(YSZ) of two different thickness like 0.05mm and 0.2mm with hazelnut Bio-Diesel blend HBD20(20% hazelnut Bio-Diesel and 80% Diesel by volume)as fuel. Experimental trials were carried out with the above bio-diesel blend as fuel operated in the ceramic coated engine working at all loads from minimum to maximum. A comparative analysis was made with the results obtained from experimental trials conducted on ceramic coated engine with two different thickness fuelled with HBD20 as fuel and conventional engine with normal diesel as fuel. Parameters selected for comparison are, exhaust emission characteristics like NOx emissions, CO emissions, smoke density, and total and partially unburned HC emissions and performance parameters like brake specific fuel consumption (BSFC), brake Thermal efficiency (BTHE), and exhaust gas temperatures (EGT). In this work engine coated with Yttria Stabilized Zirconia(YSZ) of 0.2mm thickness is showing better performance than engine with combustion chamber coated with 0.05mmthickness and also showing almost equal performance when compared with conventional engine with normal diesel as fuel in performance parameters and considerable decrease in exhaust emissions like carbon monoxides (CO), hydro carbons (HC) and slight increase in oxides of nitrogen (NOx). Yttria Stabilized Zirconia(YSZ) ceramic coated engine with 0.2mm thickness fuelled with Bio-diesel blend HBD20 prepared from hazelnut bio-diesel showing almost equal performance when compared with conventional engine with diesel as fuel in the present work.
