Patent number: 10550800Abstract: Various methods and systems are provided for reducing cylinder-to-cylinder variation in exhaust gas recirculation. In one embodiment, a system comprises a first cylinder group of an engine having a first number of cylinders, a second cylinder group of the engine having a second number of cylinders that is not an integer multiple of the first number of cylinders, and an exhaust system coupled to the first cylinder group and the second cylinder group. In at least one mode of operation, the exhaust system has exhaust ports of the first cylinder group fluidly coupled to an intake of the engine and exhaust ports of the second cylinder group fluidly decoupled from the intake.Type: GrantFiled: October 18, 2016Date of Patent: February 4, 2020Assignee: Transportation IP Holdings, LLCInventors: Vijayaselvan Jayakar, Amit Kumar Sharma, Jennifer Anne Lachapelle, Trideep Singh

Patent number: 9702323Abstract: A charge air cooling chamber has a lower wall with an orifice in the lower wall. A condensate pipe is fluidly connected to drain exhaust fume condensate from the orifice into a collection tank. A vent pipe is fluidly connected to vent fumes from an upper opening of the collection tank to an exhaust stack. A loop seal is fluidly connected to drain condensate from a lower opening of the collection tank. Exhaust gas moisture condensate drains from the cooling chamber into the collection tank, via the continuously open orifice. Exhaust gas moisture condensate fumes vent from the collection tank to the exhaust stack.Type: GrantFiled: March 17, 2015Date of Patent: July 11, 2017Assignee: General Electric CompanyInventors: Derek Paschal, Charles Bernard Atz, Vijayaselvan Jayakar, Laus Lynd Deo
