摘要： 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.

摘要： An electromagnetic drive system for repeatedly opening and closing a valve of an internal combustion engine is comprised of an electromagnetic drive mechanism and a damper mechanism. The electromagnetic drive mechanism comprises a pair of electromagnets, an armature disposed between the electromagnets and a pair of springs setting the armature at a neutral position between the electromagnets when both the electromagnets are de-energized. The electromagnets are alternately energized and de-energized according to a control signal. The damper mechanism is interlocked with the electromagnetic drive mechanism and functions to decrease a speed of displacement of the valve at a terminating period of each of a valve-closing stroke and a valve-opening stroke of the valve.

摘要： A drive shaft is synchronously rotated with a crankshaft of an internal combustion engine. A cylindrical hollow cam shaft is rotatably disposed about the drive shaft keeping a first cylindrical clearance therebetween. The cam shaft is formed with at least one cam that actuates an engine valve for opening and closing the same. A bearing bears a given portion of the cam shaft keeping a second cylindrical clearance therebetween. A movement transmitting mechanism transmits a torque of the drive shaft to the cam shaft while converting a rotation movement of the drive shaft to a swing movement of the cam shaft. The thickness of the first cylindrical clearance is smaller than that of the second cylindrical clearance.

摘要： A variable valve gear for an internal combustion engine includes: a cam base portion integrally or separately provided in a camshaft, and immovably fixed to the camshaft; a cam lobe portion connected to the cam base portion so as to swing and shift between a first state where the cam lobe portion is positioned to project from an outer circumference of the base portion and a second state where the cam lobe portion is positioned to be lower than the cam base portion in the first state; a lock mechanism locking the cam lobe portion in the first and second state; and a biasing member biasing the cam lobe portion to be shifted to the first state, to such an extent that the cam lobe portion is shifted to the second state by reaction force from a cam follower when the locking mechanism is unlocked.

摘要： A variable valve actuation device for an internal combustion engine includes a variable valve timing mechanism and a valve timing restricting mechanism. When the operating state of the variable valve timing mechanism is in the phase restricting state and the operating state of the variable valve timing mechanism is changed to the phase releasing state on the basis of pressing the accelerator pedal, a torque limiting control is then performed to limit an increase in the torque of the internal combustion engine. With this control the rate of increase of the torque is set less than the rate of increase of the torque corresponding to the operation of pressing the accelerator pedal by retarding and correcting the ignition timing. Thus, when the operating state of the variable valve timing mechanism is changed from the phase restricting state to the phase releasing state, thereby reducing discomfort experienced by the driver.
