摘要： The present invention relates to a variable valve operating device and a valve opening amount adjustment method, and can accurately control the amount of in-cylinder air and the strength of a swirl flow. The variable valve operating device according to the present invention includes a valve mechanism that can select a dual valve variable control mode in which the valve opening amounts of a first valve and a second valve, which are of the same type and provided for the same cylinder, can be varied continuously or in multiple steps. A valve opening amount difference is provided when the valve opening amounts are minimized in the dual valve variable control mode so that the valve opening amount of the first valve is larger than that of the second valve. In addition, adjustments are made so that the minimum valve opening amount of the first valve does not vary from one cylinder to another.

摘要： A valve drive system comprises a power transmitting mechanism (13) that converts rotary motion of an electric motor (12) into opening and closing motion of an intake valve (3) provided in a cylinder (2) of an internal combustion engine (1) to transmit power from the electric motor (12) to the valve (3) via a cam (152); and a rotational angle restricting mechanism (16) that is provided in a motion transmission path that extends from the electric motor (12) to the cam (152) and restricts rotation of the cam (152) within a predetermined angular range that is set so that a piston (5) of the engine (1) and the intake valve (3) do not interfere with each other. The rotational angle restricting mechanism (16) comprises a flange (161) that rotates as a unit with a camshaft (151) and forms a slotted groove hole (161a) thereon; and a stopper pin (162) that is inserted into and retracted from the groove hole (161a).

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.

摘要： A variable valve operating device that makes it possible to reduce the loss in driving force transmission from a camshaft to a valve during a valve lift is provided. The rotary motion of a drive cam is transmitted to a swing member via intermediate rollers. A coupling member couples the intermediate rollers, to a swing fulcrum that is fastened to a control shaft. The swing fulcrum is positioned eccentrically to the center of the control shaft. Further, when the control shaft is positioned at a predetermined rotation position, the swing fulcrum is positioned so that the control shaft is placed between the swing fulcrum and the intermediate rollers. Preferably, the swing fulcrum, the control shaft, and the intermediate rollers are aligned.

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.
