Abstract: A variable valve timing device for an engine utilizing hydraulically actuated valves. A cam follower block, complete with radial bores, and cam followers within these bores, is pivotally mounted about a rotating camshaft. The rotating camshaft displaces the cam followers within the bores, causing the followers to displace hydraulic fluid, forcing movement of either, an intake or exhaust valve, by hydraulic force on a secondary hydraulic cylinder. The cam follower block angular position about the camshaft is mechanically adjustable during operation. Separate cam follower blocks are used for intake and exhaust valve operation such that the valve timing of the intake and exhaust valves can be changed independently.

Abstract: A valve timing controller includes: an outer rotor; an inner rotor relatively rotating inside of the outer rotor; a torsion coil spring having a fixed end connected with the inner rotor, and a free end connected with the outer rotor; and a bush rotor coaxially projected from the outer rotor or the inner rotor to support the torsion coil spring in a radial direction. The torsion coil spring biases the inner rotor while being connected with the outer rotor by being torsionally deformed according to a relative rotation of the inner rotor to the outer rotor. A load acting from a first turn of the torsion coil spring adjacent to the free end is smaller than a load acting from a wound part of the torsion coil spring between the first turn and the fixed end.

Abstract: An electric variable valve timing apparatus includes a sprocket unit and an electric motor. The electric motor is fixed to a chain cover with bolts. The chain cover includes plural bosses each having an internal thread to which one of the bolts is threaded. The bosses extend from the chain cover toward the sprocket unit to positions at which the bosses face an outer periphery of the sprocket unit in a radial direction. The bosses are arranged such that, when the sprocket unit moves downward from an attaching position, at which the sprocket unit is attached to the camshaft, at least two bosses are engaged with the sprocket unit to restrict downward movement of the sprocket unit, and that the sprocket unit is allowed to move between a location outside of a space covered by the chain cover and the attaching position.

Abstract: A control device for an internal combustion engine includes a controller. The controller controls the relative rotation phase of the exhaust camshaft in accordance with the relative rotation phase of the intake camshaft. When a request for locking the relative rotation phase of the intake camshaft at an intermediate phase is generated, the controller controls the relative rotation phase of the exhaust camshaft such that the relative rotation phase of the exhaust camshaft is changed to a phase corresponding to the intermediate phase independently from the relative rotation phase of the intake camshaft.
