In one example, a system includes a first turbine having an exit for discharging a main fluid flow and a second turbine having an inlet for receiving at least a portion of the main fluid flow. A main conduit fluidically couples the exit of the first turbine to the inlet of the second turbine. A transition conduit is coupled with the main conduit and includes a volute passageway curving around the main conduit. The volute passageway includes a slot that follows a route around the curving volute passageway and opens into an interior of the main conduit.

Publication number: 20140013740Abstract: 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 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: ApplicationFiled: July 16, 2012Publication date: January 16, 2014Applicant: 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

Patent number: 7878172Abstract: Various embodiments of the invention relate to an intake channel of an internal combustion engine in which an adjustable position guide vane is configured to modify the velocity distribution inside the intake channel in order to vary the mean swirl number generated by the channel. The intake channel may comprise a combination of two or more ports, which can be helical or tangential, depending on their shape. By varying the velocity distribution inside the intake channel it is possible to vary the mean swirl number in an internal combustion engine. Contrary to existing systems to vary the swirl in internal combustion engines, the invention proposed does not require the separation of both ports inside the intake channel by a wall in order to achieve a variation in the swirl.Type: GrantFiled: June 3, 2009Date of Patent: February 1, 2011Assignee: General Electric CompanyInventors: Jassin Fritz, Rodrigo Rodriguez Erdmenger
