Publication number: 20090130928Abstract: A cooling system for a marine engine having a turbocharger provides for the flow of coolant through heat emitting objects prior to flowing through a coolant jacket of the turbocharger itself. This avoids the potentially disadvantageous circumstance of directing cold water directly from a body of water through the cooling jacket of the turbocharger. Both open loop and closed loop versions of the invention are illustrated and described.Type: ApplicationFiled: July 20, 2007Publication date: May 21, 2009Inventors: Christopher J. Taylor, Timothy S. Reid, Richard A. Davis, David J. Belter, Klaus Fuoss

Patent number: 7264520Abstract: A cooling system for an outboard motor pumps water from a body of water through certain selected portions of the outboard motor and through a heat exchanger which, in turn, comprises a coolant conduit that is directed to conduct the coolant in thermal communication with various portions of the outboard motor. The engine block is cooled by a flow of the coolant and an engine head is cooled by a flow of water from the body of water. Other heat emitting devices are connected in thermal and fluid communication with the water and coolant conduits.Type: GrantFiled: October 24, 2006Date of Patent: September 4, 2007Assignee: Brunswick CorporationInventors: Christopher J. Taylor, David J. Belter, Klaus Fuoss, Scott M. Westpfahl, Daniel J. Balogh

Patent number: 7021268Abstract: A crankshaft is provided with a plurality of counterweights which are asymmetrically formed so that one surface has a shape which induces a flow of air and oil mist in a preselected and preferred direction. This shape also improves the aerodynamic characteristic of the counterweight and reduces the friction that the counterweight would otherwise experience as it rotates about the rotational axis of the crankshaft. A tapered surface is provided on a lower surface of each crankshaft and the tapered surface is positioned at a leading edge of each counterweight.Type: GrantFiled: October 29, 2004Date of Patent: April 4, 2006Assignee: Brunswick CorporationInventor: Klaus Fuoss

Patent number: 6701884Abstract: An overhead cam motorcycle engine includes a cylinder head, a cam cover coupled to the cylinder head, a sealing gasket, and a substantially rigid insert. The cylinder head includes an aperture that is substantially axially aligned with an engine camshaft axis. The resilient gasket includes a sealing jacket that defines an opening. The gasket is positioned between the cylinder head and the cam cover such that the sealing jacket occupies the aperture. The insert is positioned in the opening in the sealing jacket to seal the cylinder head and cam cover interface.Type: GrantFiled: May 3, 2002Date of Patent: March 9, 2004Assignee: Harley-Davidson Motor Company Group, Inc.Inventors: Andreas Schneider, Klaus Fuoss, Jeffrey P.

Patent number: 6702054Abstract: A thermostat housing assembly for a motorcycle engine includes a body portion defining a cavity and an inlet port communicating with the cavity. The inlet port is configured to be directly connected to a water jacket outlet. The thermostat housing assembly further includes a return port communicating with the cavity and configured to be coupled to a return line. A thermally-responsive valve in the cavity selectively prevents and allows communication between the cavity and the return port. Preferably, the thermostat housing assembly further includes a second inlet port communicating with the cavity and configured to be directly connected to a second water jacket outlet. Further preferably, the first and second inlet ports are substantially parallel to each other and the first inlet port is longer than the second inlet port. Each inlet port includes a connector for connecting the inlet port to a water jacket outlet.Type: GrantFiled: December 20, 2001Date of Patent: March 9, 2004Assignee: Harley-Davidson Motor Company Group, Inc.Inventors: Andreas Schneider, Klaus Fuoss, Stefan Fegg

Patent number: 6612270Abstract: An coolant pump for an internal-combustion engine including a housing, a cover sealingly coupled to the housing, an impeller assembly located between the housing and the cover, the impeller assembly defining a longitudinal axis and being rotatable about the longitudinal axis; and a flange positioned between the housing and the cover adjacent the impeller assembly such that the flange and the cover define a first cavity, the flange and the housing define a second cavity, and the flange includes an opening fluidly connecting the first and second cavities, the flange being contoured to at least partially surround the impeller assembly. Preferably, the pump also includes a nozzle contoured to direct a coolant from the first cavity toward the second cavity and onto the impeller assembly, and wherein the nozzle has an intake side communicating with the first cavity and a discharge side communicating with the second cavity.Type: GrantFiled: December 19, 2001Date of Patent: September 2, 2003Assignee: Harley-Davidson Motor Company Group, Inc.Inventors: Stefan Fegg, Klaus Fuoss

Patent number: 6591930Abstract: A motorcycle engine capable of being supported within a frame. The engine includes a cylinder head having an upper peripheral edge and a valve cover having an assembled width and a lower peripheral edge substantially corresponding in shape to the upper peripheral edge of the cylinder head. The valve cover includes first and second portions coupled together along an engagement surface that does not extend across the entire assembled width of the valve cover. The second portion is separable from the first portion along the engagement surface to facilitate removal of the first portion from the engine. In one aspect of the invention, the first and second portions are separate castings.Type: GrantFiled: July 6, 2001Date of Patent: July 15, 2003Assignee: Harley-Davidson Motor Company Group, Inc.Inventors: Jeffrey P. Coughlin, Brent Lincoln Reid Thompson, Brian Scott Kennedy, Andreas Schneider, Klaus Fuoss

Patent number: 6494177Abstract: An oil-pump drive for an internal-combustion engine, in particular for a motorcycle. The drive includes an oil pump, in the housing of which is arranged at least one rotor member for supplying a volumetric flow of oil, wherein the rotor is driven via the crankshaft of the internal-combustion engine. It is proposed that the rotor of the oil pump is connected to a shaft driven directly by the crankshaft. In this way, the oil pump is directly driven in a simple manner.Type: GrantFiled: March 15, 2001Date of Patent: December 17, 2002Assignee: Harley-Davidson Motor Company Group, Inc.Inventors: Klaus Fuoss, Stefan Fegg

Patent number: 6012745Abstract: In the case of the pipe connection of two overlapping pipes a flexible ring is arranged between the interior pipe and the exterior pipe and, before the bracing, is axially displaceable on the interior pipe. The flexible ring and the exterior pipe have a spherical interacting outer and inner contour which ensures the angular mobility. The fixing of the pipe connection after the adjustment takes place by two tensioning bows which are fixedly mounted on the exterior pipe. This permits a particularly easy handling during the adjustment and the fixing of the pipe connection.Type: GrantFiled: July 6, 1998Date of Patent: January 11, 2000Assignee: Dr. Ing. h.c.F.
