Abstract: An embedded-component-type actuator is provided. The actuator includes an output shaft that is rotated, a planetary gear set that forms an overlapping section coaxially with the output shaft, and a motor that is coupled to the overlapping section of the planetary gear set. A sensing controller detects a rotation angle of the output shaft. The output shaft passes an actuator housing and the planetary gear set, the motor, and the sensing controller are arranged in series, thus minimizing a package. Additionally, the actuator is applied as the power source of a CVVD system to improve mountability to a complex engine room due to the space occupancy minimization.

Abstract: A fixture assembly includes a primary gage member, camshaft gages, a crankshaft gage and an engine gage, all of which have planar datum surfaces that are each dimensionally located relative to the primary gage member planar datum surface. The engine gage includes an engine datum surface, and is sized and shaped to receive, support and dimensionally locate the engine. An engine block datum surface is configured to be positioned on the engine datum surface thereby locating the engine relative to the primary gage member datum surface. The primary, first, second and engine datum surfaces are fixed in a parallel relationship to each other so as to form a parallel alignment system such that when the fixture assembly datum surfaces engage and form parallel alignment with the corresponding engine datum surfaces, the camshafts and crankshaft are angularly located in a predetermined angular orientation for proper timing of the engine assembly.

Abstract: The variable valve actuating device (20) comprises a switch pin (53) slidably received in the valve lifter (24) so as to selectively abut the end surface of the valve stem as the valve lifter is actuated by the cam. The device further comprises a first spring retainer (36) attached to an intermediate part of the valve stem (32) to engage a first valve spring (35), and a second spring retainer (44) slidably engaged by an end part of the valve stem to engage a second valve spring (43). The valve stem is provided with a stem end (39) which is enlarged with respect to a part of the valve stem slidably engaging the second spring retainer so as to define a shoulder surface (40a) that engages the second spring retainer against a spring force of the second valve spring.

Abstract: An internal combustion engine has a valvetrain that includes a rocker arm assembly on which is mounted an electronic device and at least a part of a generator. The generator converts some of the mechanical energy that is transmitted through the rocker arm assemblies into electricity. That electricity may be used to power an electric latch, a transmitter, or another type of rocker arm assembly-mounted electrical device. Various generator configurations are described. In some configurations, the generator is piezoelectric. In other configurations, the generator is electromagnetic. In some configurations, the generator is driven by force transmitted by the rocker arm assembly from a cam. In some configurations, the generator is driven by vibrations.

Abstract: A camshaft may include a shaft as well as a sliding element that is disposed on the shaft such that the sliding element is axially displaceable along a shaft axis. The shaft may comprise an external tooth for transmitting torque between the shaft and the sliding element. The external tooth may engage a mating tooth geometry formed in a passage of the sliding element. The sliding element on its axial end faces may comprise bearing collars that with the shaft form radial supporting bearings of the sliding element on the shaft. Further, the shaft may comprise cylindrical bearing portions for forming the radial supporting bearings, wherein the bearing portions can be configured with a diameter that is smaller than a diameter circumscribed by tips of the mating tooth geometry that protrude into the passage of the sliding element.
