Analysis of Thermal Loading in a Turbocharged Gasoline Engine

The design and development of a turbocharged engine requires an understanding of the characteristics of engine performance and thermal flow. In this study a naturally aspirated gasoline engine was equipped with a turbocharger. A thin-film temperature probe was manufactured and was installed into the combustion chamber wall to measure the unsteady temperature. The unsteady heat flux at the combustion chamber wall was evaluated by a one dimensional unsteady conduction equation with the wall temperature and temperature gradient.
