    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.

    摘要： A swing cam to actuate engine valves is rotatably disposed about a drive shaft. A first eccentric cam is tightly disposed on the drive shaft. A ring-link is rotatably disposed on the first eccentric cam. A second eccentric cam is tightly disposed on a control shaft which rotates to a given angular position in accordance with an operation condition of an associated internal combustion engine. A rocker arm is rotatably disposed on the second eccentric cam. A rod-link extends between the rocker arm and the swing cam. A first connecting pin pivotally connects a first arm portion of the rocker arm with the ring-link. A second connecting pin pivotally connects a second arm portion of the rocker arm with an end of the rod-link. A third connecting pin pivotally connects the other end of the rod-link with the swing cam. The first connecting pin is fixed to either one of the first arm portion of the rocker arm and the ring-link.
