Abstract

Embodiments for cooling a turbine of an engine are provided. In one example embodiment, an internal combustion engine comprises a turbocharger including a turbine having a coolant jacket integrated in a housing of the turbine, and an oil circuit coupled to the coolant jacket of the turbine. By cooling the turbine with the oil circuit, the turbine may be constructed from less-heat resistant materials.
