Abstract
Conservation of energy and improvement of efficiency has always been the major area of concern for the automobile engineering. During the combustion stroke on an IC engine, a lot of heat is generated inside the combustion chamber, nearly thirty three percent of heat is absorbed by the cylinder walls, valves, piston, and etc. thirty three percent goes to the surrounding buy exhaust gases, the rest thirty four percent is used for the shaft work. By this study we aim to minimize the emission to the surrounding from the combustion chamber. The transfer of heat can be minimized by applying Thermal barrier coating on the various components of I.C. engine. A TBC is a ceramic material usually consisting of duplex structure the top coat and the bond coat. After studying various journals, we have found some TBC material candidate which could be used in our experiment. To find the optimal material, the method called as Simple Additive Weighted (SAW) method is used which is a non-traditional optimizing method under the category of Multiple Attribute Decision Making method.
