  • Publication number: 20060231064
    Abstract: A direct injection fuel injector includes a nozzle tip having a plurality of passages allowing fluid communication between an inner nozzle tip surface portion and an outer nozzle tip surface portion and directly into a combustion chamber of an internal combustion engine. A first group of the passages have inner surface apertures located substantially in a first common plane. A second group of the passages have inner surface apertures located substantially in at least a second common plane substantially parallel to the first common plane. The second group has more passages than the first group.

  • Publication number: 20060112911
    Abstract: A variable compression ratio mechanism for an internal combustion engine that has an engine block and a crankshaft is disclosed. The variable compression ratio mechanism has a plurality of eccentric disks configured to support the crankshaft. Each of the plurality of eccentric disks has at least one cylindrical portion annularly surrounded by the engine block. The variable compression ratio mechanism also has at least one actuator configured to rotate the plurality of eccentric disks.

  • Patent number: 6769635
    Abstract: A fuel injector includes a homogenous charge nozzle outlet set and a conventional nozzle outlet set controlled respectively, by first and second needle valve members. One of the needle valve members moves to an open position while the other needle valve member remains stationary for a homogeneous charge injection event. The former needle valve member stays stationary while the other needle valve member moves to an open position for a conventional injection event. One of the needle valve members is at least partially positioned in the other needle valve member. Thus, the injector can perform homogeneous charge injection events, conventional injection events, or even a mixed mode having both types of injection events in a single engine cycle.

  • Patent number: 6230855
    Abstract: An electrically-operated disc brake assembly for vehicles is disclosed in which a friction member is adapted to be applied to a rotatable brake disc by a brake-applying apparatus including an electric motor, and transmission in the form of a linear actuator comprising a screw device adapted to apply an axially-directed brake-applying force to the friction member in response to operation of the motor. The screw device comprises inner and outer co-operating screw-threaded members, and one of the members is adapted to co-operate with the armature of the electric motor.

  • Patent number: 6205783
    Abstract: A reservoir assembly for a vehicle hydraulic braking system includes two chambers (2, 3) for the storage of hydraulic fluid. The reservoir assembly is provided with a structure for increasing the effective volume of one of the chambers (2), for example a bellows (12) or a bucket (30), and which may be operable in conjunction with the fitting of a filler cap (17) to seal a filler opening (5) for that chamber. This enables a volume of fluid to be accommodated in a chamber of increased volume, thereby substantially eliminating the possibility of volume in excess of a given volume from overflowing from the chamber (2, 3). When the reservoir assembly is installed in a vehicle braking system of a brake-by-wire electro-hydraulic type (EMB) having a first power circuit (51), and a second back-up hydrostatic circuit (60), the one chamber (2) supplies fluid to the hydrostatic circuit, and the other chamber (3) supplies fluid to the power circuit.

  • Patent number: 6145634
    Abstract: In an electrically-operated disc brake assembly for a vehicle in which a friction member (10) is applied to a brake disc by a brake-applying means including an electric motor (5) which forms part of the assembly and a linear actuator (15) in the form of a screw device apply an axially directed brake-applying force to the friction member (10) in response to operation of the motor (5), the linear actuator (15) comprises differential screws (16, 19) which translate rotation of the motor (5) into axial movement of the friction member (10) in a brake-applying, direction.

  • Patent number: 6098763
    Abstract: An electrically operated disc brake assembly for vehicles of the kind in which a friction member (9) is adapted to be applied to a rotatable brake disc (2) by a brake applying mechanism which includes an electric motor (3) and a transmission which is adapted to apply an axially directed brake applying force to the friction member (9) in response to operation of the motor (3) so that the transmission acts on the friction member (9) at circumferentially spaced locations. This produces a substantially even loading across the friction member/disc interface, reducing the magnitude of the reaction torque. In one embodiment, the transmission comprises a pair of axially spaced screw devices (4,5) which are rotatable by the motor (3) acting through a common gear train (6), and the motor may further be provided at the center of mass of the brake.
