Patent number: 11554334Abstract: Systems and apparatuses include a generator set including a chassis, an engine mounted to the chassis, an inverter coupled to the engine, and a housing coupled to the chassis. The engine and inverter are contained within the chassis and the housing. An air cleaner is sized to fit within the housing and includes an air cleaner housing defining an inlet and an outlet, and a sealing surface positioned between the inlet and the outlet, and a cover pivotably coupled to the air cleaner housing and including a carrier sized to be received within the air cleaner housing. The cover includes an air filter receiving feature structured to support an air filter and position the air filter between the inlet and the outlet, and a carrier flange structured to seal a portion of the air filter between the sealing surface and the carrier flange when the cover is arranged in a closed position.Type: GrantFiled: November 26, 2019Date of Patent: January 17, 2023Assignee: Cummins Power Generation IP, Inc.Inventors: Hans L.

Patent number: 8459216Abstract: An apparatus is disclosed including a fan producing an outlet fluid flow, and an inlet receiving an inlet stream and operably coupled to the fan. The apparatus further includes a divider separating the outlet flow into a first outlet stream and a second outlet stream, a first flow path directing the first outlet stream to a first heat transfer device thermally coupled to a first heat generating device, and a second flow path directing the second outlet stream to a second heat transfer device thermally coupled to a second heat generating device. In certain embodiments, the first and second heat transfer devices are a radiator and a surface of a generator, and the first and second heat generation devices are an internal combustion engine and the generator.Type: GrantFiled: April 5, 2010Date of Patent: June 11, 2013Assignee: Cummins Power Generation IP, Inc.Inventors: Anthony T. Klejeski, Benjamin J. Kirchoff

Patent number: 8365520Abstract: A system is disclosed including a primary engine that provides vehicle propulsion and a secondary engine that drives a generator to provide auxiliary power. The system further includes a first exhaust gas passageway from the primary engine and a second exhaust gas passageway from the secondary engine. The system further includes an emission treatment device including an exhaust inlet to treat exhaust from the primary and secondary engines. The system further includes an exhaust routing device that selectively routes exhaust from the first passageway or the second passageway to the exhaust inlet. The exhaust routing device at least partially blocks the first passageway or the second passageway from fluid communication with the exhaust inlet.Type: GrantFiled: February 13, 2009Date of Patent: February 5, 2013Assignee: Cummins Power Generation IP, Inc.Inventors: Anthony T. Klejeski, Ronald J. Mellum, Lowell K. Siewert

Patent number: 5193501Abstract: A method for assembling and preloading shaft assemblies that are supported by bearings in reciprocating internal combustion engines and the resulting improved shaft assembly. The method is comprised of the steps of: placing a spring element (21) on one end of the shaft (10) wherein said spring element (21) is arranged and configured to fill any gap between the shaft (10) and the bearings (14, 15) that could arise from the accumulation of design tolerances in the shaft assembly components and arranged and configured to always exert a positive load on the shaft (10) to reduce the axial movement of the shaft (10); and securing the shaft (10) between the bearings (14, 15).Type: GrantFiled: January 31, 1992Date of Patent: March 16, 1993Assignee: Onan CorporationInventors: Anthony T. Klejeski, Curtis D. Leaf, James I. R. Butcher
