Abstract: A VVA apparatus includes a control shaft arranged rotatable in accordance with the engine operating conditions, an alteration mechanism for changing a lift amount and an operating angle of an engine valve in accordance with rotation of the control shaft, and a drive mechanism for rotating the control shaft and including an electric motor and a reduction mechanism. The reduction mechanism has a reduction ratio set to be larger when the valve is under small lift-amount and operating-angle control than when the valve is under large lift-amount and operating-angle control.

Abstract: In a valve operating apparatus, torque is transmitted from an eccentric drive cam attached to a drive shaft through a multinodular-link motion-transmission mechanism including a link arm, a rocker arm, and a link rod to a rockable cam to cause an engine valve to open and close. Also provided is a control cam whose geometric center is displaced from a control shaft. By way of eccentric rotary motion of the control cam, a valve lift of the engine valve is variably controlled. Lubricating oil supplied from an oil passage formed in the drive shaft via a first communicating passage formed in the drive cam into a clearance between the link arm and the drive cam, is forcibly fed via a second communicating passage into a pivotally linked portion between the link arm and the rocker arm by oscillatory pumping action created by eccentric rotary motion of the drive cam.

Abstract: In an internal combustion engine with two cylinder banks, each cylinder bank having a cylinder head mounting thereon a valve operating device enabling both valve timing and valve lift characteristic to be varied, each valve operating device drives an engine valve through an eccentric cam, a substantially ring-shaped link, a rocker arm, a rod-shaped link, and a rockable cam, by rotation of a drive shaft. A control shaft varies the attitude of the rocker arm via a control cam by rotary motion thereof, in order to change a valve lift characteristic of the engine valve. As viewed in the same axial direction, a lifting direction of the rockable cam relative to a rotational direction of the drive shaft is the same in the two cylinder banks.

Abstract: In a VVA apparatus for an internal combustion engine wherein the position of contact of a cam face of a VO cam with respect to the top face of a valve lifter is changed in accordance with a change in a rocking fulcrum of a rocker arm to alter the valve lift, the maximum valve lift is obtained in a first rotated position of a control shaft where an axis of a control cam is adjacent to a driving shaft. The minimum valve lift is obtained in a second rotated position of the control shaft where the axis of the control cam is positioned near a first pivotal point of the rocker arm and a crank arm with respect to a first line connecting the axis of the control shaft and the axis of the control cam upon the maximum valve lift.
