Internal combustion engine with cylinder head and turbine

摘要

The disclosure relates to an internal combustion engine which is optimized with regard to the cooling of a turbine. The engine has at least one cylinder head and block, forming at least one cylinder, and at least one turbine. Each cylinder has at least one exhaust opening for discharging the exhaust gases from the cylinder. An exhaust gas line is connected to each exhaust opening, the exhaust gas lines converging to produce at least one combined exhaust gas line, thereby forming at least one exhaust manifold, which opens into the at least one turbine having a turbine housing. The turbine has at least one flow channel conducting exhaust gas through the turbine housing, and at least one coolant passage integrated in the housing forming a cooling facility. At least one chamber is arranged between the at least one coolant passage and the at least one flow channel conducting exhaust gas.

主权项

1. A method of cooling a turbine of an engine comprising:
directing exhaust gas through a flow channel of a turbine housing; and directing coolant through a coolant passage integrated in the turbine housing, a chamber arranged between the coolant passage and the flow channel providing a gap in the housing material between the coolant passage and the flow channel, wherein at least two chambers are arranged between the coolant passage and the flow channel conducting exhaust gas, a common dividing wall of the at least two chambers extending between the coolant passage and the flow channel and serving as a thermal bridge.
