摘要： A rocker arm is swingably supported by a control shaft that has an eccentric control cam formed thereon. The rocker arm is swung by a torque of a crankshaft of the engine. Two swing cams are swingably supported by a drive shaft and actuate respective engine valves to make an open/close operation of the same by receiving the swinging movement from the rocker arm. The rocker arm comprises a cylindrical base portion through which the control shaft passes; a first projected end that is provided at a first radially outside part of the cylindrical base portion in the vicinity of one axial end of the cylindrical base portion, the first projected end receiving the torque from the crankshaft for carrying out the pivotal movement of the rocker arm; and two second projected ends that are spaced from each other and provided at a second radially outside part of the cylindrical base portion, the second projected ends actuating the two swing cams when the rocker arm is swung. The first and second radially outside parts are opposite with respect to an axis of the cylindrical base portion.

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 system has a drive shaft having a drive cam, a rockable cam opening/closing an engine valve, a transmission mechanism converting torque of the drive cam into a rocking motion and transmitting it to the rockable cam, a control shaft, and a control cam. When the variable valve system varies a valve lift amount of the engine valve by changing the rocking fulcrum of the transmission mechanism, the rocking fulcrum during a small valve lift control is set in an area outside an arc locus drawn with the drive shaft being a center of the arc and passing through a rocking fulcrum position positioned at a maximum valve lift and also inside an arc locus drawn with a pivot of the one end side of the transmission mechanism being a center of the arc and passing through the rocking fulcrum position positioned at the maximum valve lift.

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.
