Patent number: 11421784Abstract: Various systems and methods are provided for utilizing a crankshaft lip seal over the course of a first overhaul life and a second overhaul life. In one example, a method includes installing the crankshaft lip seal between a flywheel housing and a crankshaft of an engine and operating the engine with the crankshaft lip seal. The method further includes removing the crankshaft lip seal, re-machining a floating seal sleeve coupled to the crankshaft or the flywheel housing, and replacing a lip. The crankshaft lip seal is then re-installed between the flywheel housing and the crankshaft and the engine operated with the re-installed crankshaft lip seal.Type: GrantFiled: October 22, 2020Date of Patent: August 23, 2022Assignee: Powerhouse Engine Solutions Switzerland IP Holding GmbHInventors: Sandeep Namadev Kamble, Michael Mendoza, Kamala Hasan Pethuraj, John Stephen Roth

Patent number: 8857156Abstract: In accordance with the embodiments of the present invention, an engine is disclosed. The engine includes at least one donor cylinder and at least one non-donor cylinder coupled to an intake manifold feeding intake air and an exhaust manifold. The exhaust manifold is configured to carry an engine exhaust emission from the donor cylinder and the non-donor cylinder. The engine also includes an exhaust gas recirculation manifold extending from the donor cylinder to the intake manifold for recirculating a donor cylinder exhaust emission from the donor cylinder to the donor, and non-donor cylinders via the intake manifold. The engine further includes an after-treatment system and a sensor configured to sense a temperature of the engine exhaust emission and a device configured to receive a sensing signal from the sensor and to control a parameter of the engine and a component of the engine in response to the sensing signal.Type: GrantFiled: April 27, 2012Date of Patent: October 14, 2014Assignee: General Electric CompanyInventors: Roy James Primus, Luke Michael Henry, Paul Gerard Nistler, James Robert Mischler, John Stephen Roth
