This study presents the development of a new sheet metal turbine housing for a turbo diesel engine that improves diesel vehicle emission and fuel economy. Compared to a conventional solid casting housing, it can realize earlier catalyst light-off using less heat mass and has a longer engine stop period due to higher heat retention through its unique hollow structure constructed with sheet metal. For anticipated thermal deformation, a casting and sheet metal hybrid structure is adopted as a countermeasure to ensure concentricity of the turbine shaft. Consequently, this sheet metal turbine housing shows high environmental performance and reliability.
