    Abstract: A control method using a continuous variable valve duration apparatus implements a continuous variable valve duration apparatus which includes a wheel mounted on a camshaft and having a wheel key so as to control duration of an intake valve of an engine, a cam unit having a cam and a cam key, adapted such that the camshaft is inserted thereinto, and being disposed so as to vary relative phase of the cam with respect to the camshaft, an inner bracket connected with the wheel key and the cam key, a slider housing being adapted such that the inner bracket is rotatably inserted thereinto and disposed so as to move vertically with respect to the engine, a controller varying a position of the slider housing so as to adjust rotation center of the inner bracket, and a guide unit guiding motion of the sliding housing. The control method includes calculating a required air amount for maintaining idle rotation speed of the engine by the controller when the engine is an idle state; mapping a supplied air amount in accordance with duration of the intake valve or the exhaust valve by the controller; setting a target valve duration for supplying the required air amount of the engine by the controller; and controlling duration of the intake valve or exhaust valve according to the set target valve duration by the controller.

    Abstract: A valve opening and closing timing control apparatus includes a drive-side rotational body, a driven-side rotational body, an intermediate lock mechanism which selectively switches between a lock state where displacement of a relative rotational phase of the driven-side rotational body relative to the drive-side rotational body is restrained in an intermediate lock phase and an unlock state where the lock state is released, and an electromagnetic valve. At a time of predetermined operation of an internal combustion engine, a value of the drive current is set as a boundary current, and the value of the drive current to be set as the boundary current differs, by a predetermined value, from a value of the drive current at a time when the unlock state was switched to the lock state due to the change of the drive current.

    Abstract: A valve timing controller includes a driving rotor, a driven rotor, a planetary rotor, a planetary carrier, and an elastic component to produce a restoring force biasing the planetary rotor to an eccentric side such that the driving rotor is inclined to the driven rotor. The driving rotor has an inclination angle θ1 relative to the driven rotor in a first inclination state where the driving rotor is in contact with the driven rotor on both sides in the axial direction. The inclination angle θ1 is smaller than an inclination angle θ2 in a second inclination state where the driving rotor is in contact with the driven rotor on both sides in the radial direction, and is smaller than an inclination angle θ3 in a third inclination state where the driving rotor is in contact with the camshaft on both sides in the radial direction.

    Abstract: Provided is an electric-motor-driven valve timing control device for an internal combustion engine with which the valve timing control device can be operated even when a portion of coils of an electric motor has broken. The electric motor has two systems of switching brushes, each system being constructed by a set of positive-electrode and negative-electrode switching brushes. When an electricity-feeding line used for electricity-feeding to one system of the two systems has broken, the valve timing control device is configured to stop energization to the other system or reduce an energization amount to the other system, after having energized the other system of switching brushes until such time that a predetermined time has expired from a start of the engine, thus enabling the relative rotational phase of a camshaft to be converted to a phase suitable for starting.

    Abstract: A variable cam timing system for an engine with at least one camshaft comprising: a housing, a rotor, and a controlled bypass. The housing has an outer circumference for accepting drive force and chambers. The rotor has a connection to a camshaft coaxially located within the housing. The housing and the rotor define at least one vane separating a chamber in the housing into advance and retard chambers. The vane is capable of rotation to shift the relative angular position of the housing and the rotor. The controlled bypass provides fluid communication between the chambers. When the valve is closed, the valve blocks passage between the chambers and when the valve is open fluid flows through the passage extending between the advance chamber to the retard chamber. A method for reducing the valve event is also disclosed.
