Patent number: 11181032Abstract: A cylinder head for use with an internal combustion engine, the cylinder head including a body having a fire deck and defining a water jacket in fluid communication with a cooling system, a first runner defined by the body and open to the fire deck to at least partially form a first valve seat, a second runner defined by the body and open to the fire deck to at least partially form a second valve seat, and a channel defined by the in fluid communication with the water jacket and positioned between the first runner and the second runner. The channel, in turn, includes a first inlet through which a first flow enters the channel, a second inlet through which a second flow enters the channel, and where the first inlet and the second inlet are oriented such that the first flow and the second flow interact with one another to create a turbulent region within the channel.Type: GrantFiled: September 18, 2018Date of Patent: November 23, 2021Assignee: DEERE & COMPANYInventors: Jeremy M.

Patent number: 11028799Abstract: An anti-cavitation engine block includes a first cylinder having a first cylinder centerline, a second cylinder having a second cylinder centerline, and a first inter-cylinder wall section located between the first cylinder and the second cylinder along an axis perpendicular to the first and second cylinder centerlines. A first plurality of anti-cavitation channels is formed in the first inter-cylinder wall section. A cylinder liner is inserted into the first cylinder and has an outer circumferential surface toward which the first plurality of anti-cavitation channels open. A water jacket extends at least partially around the outer circumferential surface of the cylinder liner. The first plurality of anti-cavitation channels increase local radial thicknesses of the water jacket to deter cavitation within the water jacket and adjacent the cylinder liner during engine operation.Type: GrantFiled: August 30, 2019Date of Patent: June 8, 2021Assignee: DEERE & COMPANYInventors: Robert J. Reding, Douglas S. Brocco, Terry W. Schwickerath, Umesh A. Tol, Craig W. Lohmann

Patent number: 10001078Abstract: A cooling jacket is formed at least in part within the cylinder head mounted on an engine block defining one or more piston cylinders and one or more intake and exhaust ports in communication with each piston cylinder. The cooling jacket includes a first passageway, a second passageway and a turbulence chamber. The first passageway extends from a first flow passage and intersects the turbulence chamber at a first angular position, and the second passageway extends from a second flow passage and intersects the turbulence chamber at a second angular position different from the first angular position. A swirling action is imparted to fluid media passing through the turbulence chamber.Type: GrantFiled: September 22, 2014Date of Patent: June 19, 2018Inventors: Gerald W. Green, Richard R. Winsor, Douglas S. Brocco, Craig W. Lohmann, Alok N. Pandey, Clifford Arnold
