Assessment of Combustion, Performance and emission Features of Biodiesel in a Thermal Barrier Coated Diesel Engine

Thermal Barrier Coating technique was used to coat the piston crown with Alumina. The test was conducted in a single cylinder DI diesel engine. In common, the coating acts as a thermal barrier which improves the efficiency by dipping energy losses. In the first phase of the investigation, baseline reading of diesel was taken. The second part of the investigation, engine components was coated. And the third phase of investigation has carried the performance, combustion and emission of biodiesel in thermal barrier coated diesel engine. Thus the coating and testing were done successfully. As per our aim of improving the burning, performance and pollutant features of CI engine by Coating the Piston head with a Ceramic Coating of Alumina (Al O ) Up to 250 microns have improved the burning characteristics 2 3 like cylinder pressure and heat release rate considerably, As well as the performance characteristics like Brake Thermal Efficiency is enlarged up to 15.69 %, Mechanical Efficiency is increased up to 67.9% for TBC coated piston with Biodiesel when compared to others and Other Performance Characteristics were also increased. Notably, the Exhaust Emission like CO, Hydrocarbons ,and Oxygen were also reduced. Thus the project conducted by implementing the Thermal Barrier Coating in the Piston Head had given a good improvement in all burning, performance and pollutant features of the tested CI Engine.
