ABSTRACT – Piston is the a crucial part of an ic engine as its responsible for converting the chemical energy in to a mechanical energy. The mechanical efficiency of the piston is dependent on how conveniently and effortlessly does the piston transfer the energy. As piston bares both high level of thermal as well as mechanical stresses, it is important to learn about the allowable limits of the material used to make the piston. This work is an attempt to determine whether it is possible to reduce the thermal stresses on the piston and thus improving its life expectancy. The ultimate success of an ceramic engine would be eliminating the cooling systems and hence decreasing the cost of the engine. The objective is to create a coating of appropriate thickness and subject it to thermal and structural loads and the study the variations obtained on a coated pistons compared to an uncoated piston. SOLIDWORKS software is used to model the components and the analysis is done using ANSYS software. The results obtained and used to determine whether the ceramic material under investigation is fit for the purpose or not.
applied to the internal chamber are aimed to reduce heat which passes from the in-cylinder to the engine cooling system, so that the cooling system can be removed. If the deletion of the cooling system takes place, then there will be increase in the engine efficiency, the cost of engine is also being reduced. If the engines are coated with the heat resistant materials then it would increase the temperature and pressure inside the combustion chamber and thus it would become easy to ignite the charge during a power stroke of the engine. This would eliminate the problems caused by thermal stresses on the components of the materials as they all are shielded by ceramic coating like a cap over head on a scorching afternoon. A.
Ceramic are known for its high temperature resisting properties. A ceramic engine is an ambitious project to use these materials to reduce damages caused by thermal stresses on the engine components. This should increase performance, decrease fuel consumption and reduce pollution. This should also enable various fuels to be used (i.e. multi-fuel capability).
Index Terms: Piston, Coating, Ceramic, Analysis, thermal stress, structural loads I. INTRODUCTION The innovative studies and research will continue as long as there is a scope to improve the performance and cost of an ic engine. Ceramic engine is one among such ambitious studies. These innovative studies have been continuing and now a days there is a rapid increase in the study of ceramic engines for converting the fuel energy into the mechanical energy at the most possible rate by coating the internal combustion chambers with the low heat conducting materials, there is a rapid increase in the temperature and pressure in the internal combustion chamber, so the efficiency of the engine should be increased.

Ceramic Coating of Automotive Components
With the evolution of technology and our knowledge of materials a wide varieties of materials have been used to improve the output of automotive components. Using ceramic coating we expect to regulate the temperature variations in and out of the components. Regulating these temperature fluctuations among both internal and external engine parts can improve horsepower and performance characteristics, leading to more efficient vehicle operation. Ceramic coatings are increasingly used to provide protection between different engine parts, helping to increase wear resistance, reduce friction, and improve heat shielding. These factors have a significant influence on horsepower
By using the ceramics there is a possibility of removing the cooling systems. This happens when the ceramic coating
