    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.

    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-operating device for an internal combustion engine equipped with two cylinder banks each having a variable valve timing and working angle mechanism comprises a drive shaft, a cylindrical hollow camshaft fitted to an outer periphery of the drive shaft to be rotatable relatively about the drive shaft, a non-uniform velocity coupling including an annular disc disposed between the drive shaft and the camshaft for transmitting motion of rotation from the drive shaft to the camshaft, permitting a phase change of the camshaft relative to the drive shaft with non-uniform rotation during eccentric motion of the annular disc, and a control housing rotatably supporting the annular disc. Also provided is a decentering mechanism supporting the control housing rockably to produce the eccentric motion of the annular disc. A locus of eccentric motion of the center of the annular disc arranged in the left bank and a locus of eccentric motion of the center of the annular disc arranged in the right bank are essentially symmetrical with respect to the line perpendicular to a line segment between and including two central axes of said drive shafts of the two cylinder banks. A direction of eccentric motion of the center of the annular disc arranged in the right bank is opposite to a direction of eccentric motion of the center of the annular disc arranged in the left bank.

    摘要: An upper surface of a head part of a valve lifter has a predetermined turn back portion at which, with a valuable valve control device kept controlled to induce a maximum lift of an engine valve, a swing stroke of a rounded cam surface of a swing cam relative to the upper surface of the head part changes a traveling direction from a radially outward direction for opening the engine valve to a radially inward direction for closing the engine valve. An inlet end part of an oil hole formed in the head part is placed at a radially inside position of the upper surface other than a position where side edges of the rounded cam surface of the swing cam are in contact with the inlet end part of the oil hole when the rounded cam surface is placed in the vicinity of the turn back portion.
