INTERNAL COMBUSTION ENGINE WITH COOLED TURBINE

摘要

An internal combustion engine has a cylinder head with at least one cylinder and a cooled turbine. Each cylinder has at least one outlet opening adjoined by an exhaust line for discharging exhaust gases from the cylinder. The exhaust line issues into an inlet region transitioning into an exhaust gas-conducting flow duct of the turbine. The turbine has at least one rotor mounted on a rotatable shaft in a turbine housing. The turbine has at least one coolant duct which is integrated in the housing and which is delimited and formed by at least one wall of the housing to form a cooling arrangement. The at least one wall of the turbine housing that delimits the at least one coolant duct is provided, at least in regions, with a thermal insulation.

1. An internal combustion engine having at least one cylinder head with a cooled turbine, the internal combustion engine comprising:
at least one cylinder head having at least one cylinder, each cylinder having at least one outlet opening for discharging exhaust gases from the cylinder and each outlet opening being adjoined by an exhaust line; and a turbine having at least one rotor mounted on a rotatable shaft in a turbine housing, the turbine having, to form a cooling arrangement, at least one coolant duct integrated in the turbine housing being delimited and formed by at least one wall; wherein the at least one exhaust line of at least one cylinder issues into an inlet region, which transitions into an exhaust gas-conducting flow duct, of the turbine; and wherein the at least one wall that delimits the at least one coolant duct is provided, at least in regions, with thermal insulation.
