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： According to a control strategy, a cylinder valve control device is monitored and operation of the engine is modified. The cylinder valve control device includes a driving shaft driven by the engine to drive an intermediate member which in turn drives a cam arranged to open an engine intake valve, and a driver which is operative in response to a command to vary an amount of eccentricity of the intermediate member with respect to a shaft axis of the driving shaft. During one mode of engine operation, the intermediate member is supported in a support for rotation about an axis in eccentric condition with respect to the shaft axis to accelerate and decelerate the cam with respect to rotation of the driving shaft. During another mode of engine operation, the intermediate member is in concentric condition with respect to the shaft axis to provide a synchronous motion of the cam with rotation of the driving shaft. In response to the eccentricity of the intermediate member, the engine operation is modified.

摘要： A valve drive for an internal combustion engine, comprises a valve train which is operable in a first state to transfer the rotational motion of a low lift cam lobe to the reciprocating motion of a cylinder valve against a valve spring. The valve train is also operable in a second a sate to transfer the rotational motion of a high lift cam lobe to the reciprocating motion of the cylinder valve against the valve spring. The valve train includes a cam follower arranged to move between a first position in which the cam follower is driving relation with the low lift cam lode and a second position in which the cam follower is in driving relation with the high lift cam lobe.

摘要： A cam shaft assembly comprises a first coupling between a drive collar rotatable with a driving shaft and an annular disc at a first position spaced from the shaft axis, and a second coupling between the disc and said hollow cam at a second position angularly spaced from said first position with respect to the shaft axis. The first and second couplings are so spaced from the shaft axis that they are at varying distances from the axis of the disc during operation. Each of the first and second couplings has a movable connection with the disc to permit the variation in its distance from the axis of the disc. The disc is rotatably supported in a disc housing. A control rod is mounted for rotation and has an eccentric control cam which controls movement of the disc housing. A pivot shaft extends through the disc housing for allowing movement of the disc housing following the eccentric control cam in which said plurality of hollow cams are disposed.
