  • Patent number: 6626155
    Abstract: A motorcycle having an improved fuel tank arrangement with an opening in an upper side wall of the fuel tank that is closed by a combined fuel pump, closure plate and return port arrangement. The fuel is supplied to a fuel injection system through an arrangement including a filter and pressure regulator with the filter pressure regulator and opening all being positioned on the same side of the motorcycle and at relatively the same vertical height. The assembly may be removed from the opening without draining fuel due to its high placement in the opening.

  • Patent number: 6626145
    Abstract: An improved method and system for the control of an engine system such as the spark timing. The control senses the speed variations either during a portion of a complete cycle and a complete cycle and/or from cycle to cycle in order to determine the load on the engine from preprogrammed maps based upon the engine characteristics. From this load and the speed reading, it is possible to obtain the desired engine control. This not only reduces the costs of the system by reducing the number of sensors, but also permits adjustments to be made more rapidly.

  • Patent number: 6588529
    Abstract: A motorcycle frame and body cover arrangement that provides a very neat appearance as well as good riding posture for the rider/operator and a co-rider and also for its good leg positioning when the vehicle is stationary. The body cover covers the major portions of the frame and engine assembly but leaves the crankcase of the engine exposed for cooling and to improve the foot area. Also, the body cover pieces are arranged so as to permit changes in styling details. Portions of the body that carry weight are supported by the frame by a sub-frame that encircles the head pipe. Also, the body configuration and seating arrangement is such that a rider can be comfortably seated behind the operator and his feet will be positioned well clear of the muffler and other running components while still maintaining a comfortable position.

  • Patent number: 6590306
    Abstract: A motor scooter embodying an improved electric motor driven wheel. The electric motor for driving the wheel is quite compact and is designed so as to be nested within the disk of the wheel. The motor controller is mounted adjacent the wheel in a protected area but is cooled by airflow across it and by heat transfer to the motor housing. Oil in the motor assembly also will cool the controller. A two speed planetary gear transmission is employed that also is compact and can be nested easily within portions of the electric motor. In addition, an improved brake assembly is also mounted integrally within the motor driving mechanism.

  • Patent number: 6590310
    Abstract: A number of embodiments of rotating electrical machines and methods for winding them that provides a high space utilization and very effective winding with less likelihood of damage to the insulation of the wire of the winding during the winding process. The arrangement basically does not require the winding needle to be moved back and forth in the slot between the poles but rather employs insulating inserts that are positioned on the axial faces of the poles outside of the gaps for guiding the wire from one end to the other so as to provide the high space utilization.

  • Patent number: 6583529
    Abstract: An electrical machine having a plurality of pole pieces surrounded by bobbins and upon which individual coil windings are formed. The bobbins are formed by a insulating material in which are embedded electrical connectors that have terminal ends that afford connection to the coil windings and to an external connection for either deriving electrical power in the case the machine operates as a generator or receiving power in the event the device operates as a motor. In addition the individual coils are arranged in groups that can be connected together through internal connections in such a way to provide different electrical outputs without internal taps or redesign of the machine. Thus, cost is reduced and at the same time the device is more compact and has greater efficiency and wider utility.

  • Patent number: 6566779
    Abstract: An improved armature winding arrangement for a rotating electrical machine such as a specifically illustrated DC motor for driving a vehicle wheel. The assembly is such that the armature core can be formed from two laminated pieces that are rigidly connected to each other and held against axial movement. This eliminates the need for bonding adhesive. In addition, an improved bobbin arrangement is employed for both permitting attachment of a wiring plate directly to the core but also for retaining the ends of the individual windings to prevent them from becoming loose either during assembly or in operation.
