Abstract
Various methods and systems are provided for removing fluid from a turbocharger turbine. In one example, a turbocharger comprises a turbine including a casing housing a rotor, a drain passage coupled to the casing, and an air jet coupled to the drain passage, the air jet supplying intake air from a high-pressure compressor outlet to the drain passage.
Claims20
A turbocharger, comprising:
- a turbine including a casing housing a rotor;
- a drain passage coupled to the casing;
- and
- an air jet coupled to the drain passage, the air jet configured to supply intake air from a high-pressure compressor outlet to the drain passage.
1 more element
A system, comprising:
- an engine;
- a first turbocharger including a first turbine mechanically coupled to a first compressor;
- a second turbocharger including a second turbine located downstream of the first turbine in an exhaust flow path, the second turbine mechanically coupled to a second compressor, the second compressor located upstream of the first compressor in an intake flow path;
- a drain passage coupling the second turbine to atmosphere;
- and
- a compressed air line coupling the drain passage to an outlet of the first compressor.
3 more elements
A method, comprising:
- when a pressure of intake air at a high-pressure compressor outlet is greater than a pressure of exhaust gas downstream of a low-pressure turbine, sealing a flow of exhaust gas from the low-pressure turbine through a drain passage to atmosphere;
- and
- when the pressure of intake air at the high-pressure compressor outlet is not greater than the pressure of exhaust gas downstream of the low-pressure turbine, draining fluid from the low-pressure turbine through the drain passage.
