The Behavior of Temperature on Insulated(MgZrO3) Diesel Engine Piston With ANSYS

In an internal combustion engine, the heat energy approximately one third of total fuel input energy is converted to useful work. Since the exhaust gas temperature is not equal environmental temperature, so lot of heat energy lost with hot gases. Also heat energy is lost in cooling of engine. If we recovered heat energy which lost in cooling instead on crankshaft as useful work, then increase the efficiency of engine and improvement in fuel economy. Many researchers have done work on design improvement to increase efficiency of engine. Some researchers worked on other alternative which is thermal barrier coating on different parts of engine like as piston, liner, valves and head of cylinder. In this paper ceramic material (MgZrO3) with different coating thickness 0.35 mm and 0.50 mm are used to reduction of heat losses through conduction in piston of engine. With the application of thermal barrier coating on engine parts increase thermal efficiency, fuel combustion process and emissions controls. Here thermal barrier coating is to be done on selected piston of diesel engine with NiCrAl is bond coat material and MgZrO3 as a top ceramic coating, and in this paper conclude that increases thickness of coating causes increase top piston surface temperature.
