Patent number: 8925317Abstract: An exemplary turbocharger system for an internal combustion engine is provided. The turbocharger system includes a first turbine and a second turbine. The first turbine is in fluid communication with the internal combustion engine. The first turbine receives a first portion exhaust gas discharged from the internal combustion engine and provides a first turbine exhaust gas. The second turbine is in fluid communication with the first turbine via an inter-stage channel. The inter-stage channel transports the first turbine exhaust gas from the first turbine to the second turbine. The inter-stage channel is in thermal connection with an exhaust gas recirculation channel defined between an inlet and an outlet of the internal combustion engine. The first turbine exhaust gas flowing through the inter-stage channel is capable of being heated by a second portion exhaust gas discharged from the internal combustion engine and flowing through the exhaust gas recirculation channel.Type: GrantFiled: July 16, 2012Date of Patent: January 6, 2015Assignee: General Electric CompanyInventors: Rodrigo Rodriguez Erdmenger, Cathal Clancy, Daniel Edward Loringer, Jassin Marcel Fritz, Neil Xavier Blythe, Lukas William Johnson, Sebastian Walter Freund, Pierre Sébastien Huck, Jonathan Edward Nagurney, Yu Du, Matthias Lang, Rudolf Konrad Selmeier, Elisa Jubany Arribas
