- Thermal barrier coating (TBC) have the potential to reduce the in-cylinder heat transfer through walls by achieving wall temperatures that track the in-cylinder working-gas temperature. The aim of this paper it to evaluate novel TBC performance in a gasoline direct injection (GDI) engine by carrying out heat transfer analysis of coated components. This heat transfer analysis is given by the solution of a 3D finite element analysis (FEA) of the coated components. The combustion side boundary conditions for the FEA are obtained from the 3D CFD simulations based on a light duty, experimental, single-cylinder GDI engine. The CFD models for coated and uncoated components are validated against experimental data collected on the single cylinder engine. This routine of using CFD and FEA to determine the local surface temperatures of the coated components provides the great level of detail in terms its spatial distribution, and also allows a greater insight in understanding how do TBCs affect the spark ignition combustion process.
