摘要： A variable valve timing mechanism comprises a drive shaft including a rocker arm, a control shaft, a stopper, a first spring member and a second spring member. The rocker arm opens and closes at least one of an intake/exhaust valve in response to rotation of the drive shaft. The control shaft changes a position of the rocker arm to continuously change valve lift characteristics of the intake/exhaust valve in response to rotation of the control shaft by driving a control shaft actuator. The stopper regulates an operating range of rotation of the control shaft between upper and lower limits. The first and second spring members urge the control shaft towards the upper and lower limits, respectively. The first and second spring members return the control shaft to a balance position between the upper limit position and the lower limit position when the internal combustion engine stops.

摘要： Rotating drive shaft is connected to a crankshaft and valve cam. Valve cam lifts intake and exhaust valves that are linked by a plurality of links. The amount of lift of intake and exhaust valves is adjusted by adjusting the position of a connector pin, that passes through two links and allows for their relative rotation. The adjustment of the connector pin is configured so that it is performed from single adjustment direction using prescribed adjustment tools.
