摘要： A variable valve system has a drive shaft having a drive cam, a rockable cam opening/closing an engine valve, a transmission mechanism converting torque of the drive cam into a rocking motion and transmitting it to the rockable cam, a control shaft, and a control cam. When the variable valve system varies a valve lift amount of the engine valve by changing the rocking fulcrum of the transmission mechanism, the rocking fulcrum during a small valve lift control is set in an area outside an arc locus drawn with the drive shaft being a center of the arc and passing through a rocking fulcrum position positioned at a maximum valve lift and also inside an arc locus drawn with a pivot of the one end side of the transmission mechanism being a center of the arc and passing through the rocking fulcrum position positioned at the maximum valve lift.

摘要： An improved control device for intake and/or exhaust valves of an internal combustion engine includes a small circumference portion defined in a drive shaft at a location corresponding to that of an annular member which is eccentrically displaced for changing a rotational phase of the cams. According to this a degree of displacement of the annular member may be increased and control the cams, and thereby the engine valves, may be enhanced. Further, the cam lobe of each cam is formed such that side portions thereof are asymmetrical with respect to a center line of the cam for favorably affecting valve opening and closing timings. In addition, an improved lubricating arrangement for enhancing smooth operation and improved engine performance.

摘要： A camshaft supported in an engine cylinder head structure has a low speed (lift) cam lobe and a high speed (lift) cam lobe. A rocker arm is supported by a hydraulic lash adjuster or a rocker shaft for pivotal motion and has a sub-rocker shaft and a pin. The rocker arm is drivingly engages the low lift cam lobe. A free cam follower is supported by the sub-rocker shaft and drivingly engages the high lift cam lobe. A latch lever supported by the pin has a latch position wherein one end portion of the latch lever is in locking engagement with the free cam follower and a latch release position wherein the one end portion of the latch lever is out of engagement with the free cam follower. A hydraulic piston received in bore is in driving engagement with the opposite end portion of the latch lever to urge the latch lever against a latch lever release spring towards the latch position thereof. Hydraulic fluid communication between the bore and a hydraulic fluid passage of the cylinder head structure is established through the hydraulic lash adjuster or the rocker shaft.
