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： A main rocker arm which is pivotally mounted on a rocker shaft has one or more sub-rocker arms pivotally mounted thereon. The main rocker arm is arranged to synchronously open and close two poppet valves. Each of the sub-rocker arms can be selectively locked to the main one by way of hydraulically operated plunger arrangements. The main rocker arm is provided with a roller type cam follower which follows a low speed cam. The sub-rocker arms are provided with followers which engage high or very high speed cams. Lost motion springs which maintain the sub-rocker arms in contact with the cams are mounted on the main rocker arm.

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.

摘要： A variable valve actuating apparatus for an internal combustion engine includes an intake valve operating angle varying mechanism, and an intake valve timing varying mechanism. The intake valve timing varying mechanism includes a housing rotating in synchronization with a crankshaft, and a vane member coupled to a drive shaft for intake valve operation, and movably mounted in the housing. The vane member includes a vane defining first and second fluid pressure chambers on first and second opposite sides of the vane. A hydraulic circuit is arranged to rotate the vane member relative to the housing by supply and return of a brake fluid to and from the first and second fluid pressure chambers so as to change the intake valve maximum lift phase. Coil springs are arranged to bias the vane member relative to the housing in a direction to retard the intake valve maximum lift phase.
