Effect of Thermal Barrier Coating on Piston Head of 4-Stroke Spark Ignition Engine

Abstract

The internal combustion engine is facing a severe confront to progress automobile energy effectiveness. In the internal combustion engine most of the heat generated during combustion process is absorbed by the piston by the direct heat loss.
Thus, this reduces the indicated power and in turns the performance of internal combustion engine. In this study, the performance of the spark ignition engine was studied before and after the application of the ceramic coating on the piston crown. The experimentation was carried out on four stroke single cylinder computerized spark ignition engine for different load and different spark advance angles. There was an enhancement in thermal efficiency with reduced specific fuel consumption.
