Patent number: 11525419Abstract: An engine power module includes a water jacket, a cylinder liner, and a cylinder head. The water jacket forms a coolant supply conduit arranged in a lower coolant annulus extending around the cylinder liner and an upper coolant annulus extending around the cylinder head. The cylinder head has formed therein an injector bore, and a plurality of drill holes convergent on the injector bore. A lower coolant cavity in the cylinder head forms a coolant flow path extending circumferentially around the injector bore between a cavity inlet opening fluidly connected to the coolant supply conduit, and a cavity connection opening fluidly connected to an upper coolant cavity. The arrangement provides flows of coolant through the drill holes to cool an injector sleeve, and separate coolant flows through the lower coolant cavity and upper coolant cavity.Type: GrantFiled: October 26, 2021Date of Patent: December 13, 2022Assignee: Progress Rail Locomotive Inc.Inventors: Raji Rexavier, Joshua David Schueler, Patricia A McWade

Patent number: 9347367Abstract: A turbocharger is disclosed for use with an engine system. The turbocharger may have a housing at least partially defining a compressor shroud and a turbine shroud. The turbine shroud may form a first volute and a second volute, each having an inlet configured to receive exhaust from an exhaust manifold of the engine in a tangential direction, and an axial channel disposed downstream of the inlet. The turbocharger may also have a turbine wheel disposed within the turbine shroud and configured to receive exhaust from the axial channels of the first and second volutes, a compressor wheel disposed within the compressor shroud, and a shaft connecting the turbine wheel to the compressor wheel. The turbocharger may further have a nozzle ring in fluid communication with the axial channels of the first and second volutes at a location upstream of the turbine wheel.Type: GrantFiled: July 10, 2013Date of Patent: May 24, 2016Assignee: Electro-Motive Diesel, Inc.Inventors: Shakeel Nasir, Joshua David Schueler

Patent number: 9228485Abstract: An air handling system having a cooling assembly is disclosed. The air handling system may include a first turbocharger having a first compressor, a second turbocharger having a second compressor connected in parallel with the first compressor, and a third turbocharger fluidly connected to the first and second turbochargers. The third turbocharger may have a third compressor connected downstream of the first and second compressors. The air handling system may also include a cooling assembly connected to the first, second, and third turbochargers. The air handling system may further include a first passage fluidly connecting the first turbocharger to a first side surface of the cooling assembly, and a second passage fluidly connecting the second turbocharger to a second side surface of the cooling assembly opposite the first side surface. The first and second passages may be configured to direct compressed air into the cooling assembly in generally opposite directions.Type: GrantFiled: April 25, 2013Date of Patent: January 5, 2016Assignee: Electro-Motive Diesel, Inc.Inventors: Gary Robert Svihla, Joshua David Schueler

Patent number: 9222404Abstract: A cooling assembly having multiple coolers is disclosed. The cooling assembly may include a housing at least partially defining a first chamber and a second chamber adjacent to the first chamber and substantially isolated from the first chamber. The housing may also at least partially define first and second inlets configured to direct air into the first chamber in parallel, and first and second outlets configured to direct air out of the second chamber in parallel. The cooling assembly may also include a first cooler disposed in the first chamber, and a second cooler disposed in the second chamber.Type: GrantFiled: April 25, 2013Date of Patent: December 29, 2015Assignee: Electro-Motive Diesel, Inc.Inventors: Gary Robert Svihla, Joshua David Schueler, Jeffrey Paul Nowak
