    摘要： A control device controls intake and exhaust valves of an internal combustion engine. The device comprises a first flange provided by a cam shaft of the engine, which flange has a first radially extending elongate slit. A second flange faces the first flange with a certain clearance therebetween and is secured to a drive shaft to rotate therewith. The second flange has a second radially extending elongate slit. An annular member is disposed within the clearance and rotatable about an axis of the drive shaft. First and second pins are rotatably held by opposed sides of the annular member respectively. These pins are positioned at diametrically opposed positions with respect to a center of the annular member and slidably engaged with the first and second elongate slits respectively. A drive mechanism is employed for pivoting the annular member about a pivot axis eccentric to the axis of the drive shaft in accordance with an operating condition of the engine.

    摘要： An internal combustion engine is provided with a valve lift varying mechanism for intake valves and a valve phase varying mechanism for exhaust valves. A controller performs a control operation in response to a request to pause at least one cylinder while the engine is in operation. The control operation includes: a first operation of setting an intake valve lift to a zero-lift setpoint by the valve lift varying mechanism; and a second operation of setting an exhaust valve phase by the valve phase varying mechanism so as to set an exhaust valve opening timing to a first timing setpoint on an advance side of bottom dead center and set an exhaust valve closing timing to a second timing setpoint on a retard side of bottom dead center. The first and second timing setpoints are closer to top dead center than to bottom dead center.

A lubricating oil passage is formed in the drive cam. The oil passage has one end exposed to an oil feeding passage formed in the drive shaft and the other end exposed to a minute clearance defined between a cylindrical outer surface of the drive cam and a cylindrical inner surface of the circular opening of the link arm.

    摘要： In a valve operating apparatus of an engine capable of varying a valve lift characteristic, rotary motion of a drive cam is converted through a motion-conversion linkage including a rocker arm into oscillating motion of a valve actuation member for operating an engine valve. Also provided is a control shaft whose angular position is adjusted depending on an engine operating condition for changing a linkage attitude. The valve actuation member has an arcuate portion curved to bypass the drive shaft. The control shaft has a coaxial shaft portion and an eccentric control cam. The control cam is a fulcrum of oscillating motion of the rocker arm and the coaxial shaft portion of the control shaft is a fulcrum of oscillating motion of the valve actuation member. The fulcrums are laid out in close proximity to each other.

    摘要： In a variable valve actuation system of an internal combustion engine employing a variable valve actuator capable of variably adjusting at least intake valve closure timing depending on engine operating conditions, a processor of a control unit is programmed to phase-advance the intake valve closure timing to a predetermined timing value after a piston top dead center position and before a piston bottom dead center position on intake stroke during at least one of an engine starting period and an engine stopping period. The variable valve actuator includes a biasing device by which the intake valve closure timing is permanently biased toward the predetermined timing value.
