    摘要: Intake camshafts 10, 14 for driving valve bodies 32 (intake valve) are positioned in right- and left-hand banks, respectively. A variable valve mechanism 30 is positioned in each of the right- and left-hand banks in such a manner as to form mirror-image symmetry. The variable valve mechanism 30 includes a control shaft 60 for controlling the operating angle of the valve body. The respective control shafts in the right- and left-hand banks are controlled in symmetrical directions. The right- and left-hand intake camshafts 10, 14 rotate in opposite directions and at a speed that is synchronized with the speed of a crankshaft.

    摘要: Disclosed is a variable valve mechanism for an internal combustion engine. The variable valve mechanism accurately adjusts the valve operating angle although its structure is simple. The variable valve mechanism includes a control pin 48, which is inserted into a pin insertion hole 38 in a control shaft 16; a bearing hole 44, which is formed in a control member 26; and an adjustment pin 50, which is rotatably supported by the bearing hole 44. The adjustment pin 50 comes into surface contact with the control pin 48 to inhibit the control member 26 from rotating relative to the control shaft 16. The valve operating angle is adjusted by replacing the adjustment pin 50 with another having a different dimension B. Such adjustment pin replacement changes the distance A between the center line of the bearing hole 44 and the center line of the control pin 48, thereby changing the relative angle θ between the control shaft 16 and control member 26. When the adjustment pin 50 rotates within the bearing hole 44, the surface contact between the adjustment pin 50 and control pin 48 is maintained irrespective of the magnitude of the relative angle θ.

    摘要: The rotary motion of a camshaft is transmitted from a first drive cam to a slide surface of a swing cam arm via intermediate members so that the swing cam arm lifts a valve. In this instance, the operating characteristic of the valve changes when the rotation position of a control shaft changes to change the positions of the intermediate members on the slide surface. When the operating characteristic control mode for the valve is to be changed from variable control to fixed control, coupling means couples the swing cam arm and input arm, thereby causing a second drive cam to swing the swing cam arm. The setting for the lift amount of the valve that is obtained when the second drive cam swings the swing cam arm is not smaller than a maximum lift amount setting for a situation where the first drive cam swings the swing cam arm.

    摘要: The present invention provides a compact variable valve operating device that is capable of mechanically changing the operating characteristic of a valve. The rotation motion of a camshaft is input to the valve via a swing member. A slide surface is formed on the swing member. Intermediate members are positioned in contact with both the slide surface and drive cam surface. A support member for supporting the intermediate members is mounted on a control member. The control member can rotate in relation to the camshaft and is interlocked with a control shaft via rotation interlock mechanisms. When the control member rotates in coordination with the rotation of the control shaft, the intermediate members move along the drive cam surface and slide surface. The operating characteristic of the valve then changes in coordination with a positional change of the intermediate members.
