Abstract: A combustion air filtration apparatus for filtering combustion air for an engine is disclosed. The combustion air filtration apparatus comprises a combustion air source and a filter system fluidly coupled to the combustion air source and to the engine to receive combustion air from the combustion air source and to supply filtered combustion air for the engine. The filter system comprises a first combustion air filter, a second combustion air filter flow-parallel to the first combustion air filter, and a flow control system fluidly coupled to the first combustion air filter and the second combustion air filter to direct flow of combustion air selectively between the first combustion air filter and the second combustion air filter.

Abstract: Cooling and debris mitigation systems for use with work vehicle powertrains include a pressurized air source, a plurality of impingement outlets positioned proximate the work vehicle powertrain, and a flow network fluidly coupling the pressurized air source to the impingement outlets. A first vortex tube is positioned in the flow network and configured to separate pressurized airflow received from the pressurized air source into a hot stream and a reduced temperature stream. The first vortex tube includes a vortex tube inlet fluidly coupled to the pressurized air source, an exhaust port through which the hot stream is discharged, and a nozzle through which the reduced temperature stream is discharged. The reduced temperature stream impinges upon at least one of the targeted exterior regions of the work vehicle powertrain to provide cooling thereto and reduce debris accumulation thereon.

Abstract: An apparatus for mounting a printed circuit board within a potted member and enhancing the environmental isolation of the circuit board includes a first rigid tubular member and a second elastomeric tubular member. The elastomeric member is positioned about the rigid member and bonded thereto. The tubular members are inserted through openings in the circuit board to support the circuit board at a preselected height and provide bolt hole openings through the first rigid member for mounting the assembly at a desired location. A potting compound is applied in enveloping relation to the circuit board and elastomeric member while maintaining a clear passage through the bolt hole openings. The potting compound chemically bonds to the elastomeric member virtually eliminating water intrusion at the interface between the elastomeric member and the potting compound.
