Publication number: 20030164689Abstract: The present invention relates to a method for the automatic control of lighting devices (16), particularly of a motor vehicle, and a device for implementing the method, the brightness in a specific direction being detected by at least one directional sensor (14) which emits direction signals (SR) to a control device (10), the control device (10) switching on the lighting devices (16) after a minimum time (tb) has elapsed. The minimum time (tb) begins when the direction signals (SR) exceed or drop below a switch-on threshold (SE). The lighting devices (16) are only switched on when the direction signals (SR) lie above or below the switch-on threshold (SE) during the entire minimum time (tb). To that end, the control device (10) is connected to a timer (T).Type: ApplicationFiled: February 11, 2003Publication date: September 4, 2003Inventors: Patrick Schmitt, Norbert Hog, Bruno Hodapp, Gebhard Michenfelder, Hans Meier, Henry Blitzke, Andreas Schneider, Pierre Nonnenmacher

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.

Publication number: 20030089338Abstract: In internal-combustion engines with large numbers of cylinders, the rotational speed fractions of the cylinders are superimposed such that, when considering a rotational speed curve, no conclusions are possible any longer with respect to rotational speed fractions of individual cylinders. This requires new analyzing methods. According to the invention, contributions of individual cylinders of the internal-combustion engine to the rotational acceleration are determined by the rotational speed course of the crankshaft by individually cutting off the cylinders successively. From the thus obtained rotational speed course curves, a pulse response spectrum {right arrow over (I)} of an operating cycle is formed at least for the harmonic of the 0.5th order. In normal operation, the rotational speed course of the crankshaft is then continuously recorded above the angle of each operating cycle.Type: ApplicationFiled: October 22, 2002Publication date: May 15, 2003Inventors: Joerg Remele, Andreas Schneider, Albrecht Debelak

Patent number: 6536394Abstract: A fuel supply device is mounted to a motorcycle engine between two substantially identical air intake connections. The air intake connections each include a body portion with a projection and a flange, each extending radially from the body portion. Fasteners inserted through apertures in the flanges hold the air intake connections to the engine. The protrusion is preferably made of a resilient material, such as rubber. The flange is preferably made of a non-resilient material, such as aluminum. An aperture having an annular recess extends through the projection. The aperture is adapted to receive an internally threaded metal sleeve having an annular protrusion that surrounds the metal sleeve. A threaded fastener preferably extends through the metal sleeve and couples the fuel supply device to the projection. In the event that the fastener is excessively torqued during tightening the metal sleeve can spin in the aperture without damaging the projection.Type: GrantFiled: July 19, 2001Date of Patent: March 25, 2003Assignee: Harley-Davidson Motor Company Group, Inc.Inventor: Andreas Schneider

Patent number: 6412464Abstract: This invention relates to a chain guide rail for an internal-combustion engine, having a body portion and a pin, both made with a first material, an overmolding of a second material which covers both the pin and the body portion, and a longitudinal axis through the length of the guide rail. The pin, inserted into a housing recess in the internal-combustion engine, is restrained from moving perpendicular to the first longitudinal axis but is free to move parallel to the axis. Preferred embodiments of the present invention utilize a fastener to hold the guide rail to the housing. Preferred embodiments also utilize raised portions spaced along the guide rail which reduce the longitudinal shrinkage during cooling of the second material.Type: GrantFiled: November 10, 2000Date of Patent: July 2, 2002Assignee: Harley-Davidson Motor Company Group, Inc.Inventors: Andreas Schneider, Volker Diehm
