Patent number: 11359536Abstract: A control system for controlling a work machine includes an engine for producing power to propel the work machine during a normal operating mode, a cooling system for cooling at least the engine during the normal operating mode, and a controller for controlling the cleaning system during the normal operating mode and a clean operating mode. During the normal operating mode, the engine is running and the controller operably controls a cooling fan of the cooling system to rotate in a first rotational direction to produce a first air flow in a first direction. During the clean operating mode, the engine is not running and the controller operably controls the cooling fan to rotate in a second rotational direction to produce a second air flow in a second direction. The first rotational direction is opposite the second rotational direction, and the first direction is opposite the second direction.Type: GrantFiled: October 30, 2019Date of Patent: June 14, 2022Assignee: DEERE & COMPANYInventors: Sean P West, Steven R Sass, James A Schwalb, Paul A Wantschik, Daniel L Lucas, Jason G Knipper, Jeffrey Flippin, Jacob Henderson

Patent number: 10465595Abstract: An apparatus and method of cooling an engine exhaust generated by an engine of a work machine having a hydraulically operated implement. The work machine includes an emission control system and a cooling system having an oil cooling system configured to cool an oil of a hydraulic system and an engine cooling system configured to cool an engine coolant circulating through the engine. An exhaust pipe, coupled to the emission control system and configured to direct engine exhaust, includes an outlet disposed in a space located between an oil cooler of the oil cooling system and a radiator of the engine cooling system. An air displacement device is configured to draw air into and away from the oil cooler and the radiator and to draw the exhaust from the exhaust pipe. Exhaust from the exhaust pipe is drawn past the oil cooler and the radiator to cool the exhaust.Type: GrantFiled: April 10, 2018Date of Patent: November 5, 2019Assignee: DEERE & COMPANYInventors: Thomas Kennedy, Kevin W. Campbell, Paul A. Wantschik, Travis Graber, Kal J. Airey

Patent number: 9518499Abstract: A DEF injector cooling system may include a mechanical pump, an electric pump, and a controller. The mechanical pump may be rotatably coupled to an engine so as to be driven by the engine. The mechanical pump may be fluidly connected to the engine, a DEF injector, and a heat exchanger, and configured to pump coolant through these components. The electric pump may be fluidly connected to the DEF injector and configured to pump coolant through it. The controller may be configured to receive an ambient temperature signal indicative of an ambient temperature and power the electric pump after a shutdown of the engine for a period of time, the duration of the period of time based on the ambient temperature signal.Type: GrantFiled: January 21, 2015Date of Patent: December 13, 2016Assignee: DEERE & COMPANYInventors: Jonathan A. Dylhoff, Brent M. Hunold, Paul A. Wantschik, Mark D. Anderson
