TURBINE HOUSING FOR A TURBOCHARGER COMBUSTION ENGINE, TURBOCHARGER INTERNAL COMBUSTION ENGINE AND METHOD FOR COOLING A TURBOCHARGER INTERNAL COMBUSTION ENGINE

摘要

Turbine housing for a turbocharger internal combustion engine for marine applications with an integrally formed with the turbine housing exhaust manifold (12, 14) and a both turbine (16) and exhaust manifold (12, 14) surrounding cooling means (18, 20, 22). The cooling device is formed by a double wall (18, 20) formed, with coolant acted upon cavity (22) wherein the coolant is preferably seawater. For cooling a bearing housing (32) serving to receive a turbine bearing, a cooling circuit separate from the cooling device (18, 20, 22) of the turbine housing (10) is provided.
