摘要： A lift and operating angle varying mechanism is arranged to vary an intake valve operation angle and an intake valve lift of the engine continuously by rotating a control shaft with an actuator disposed at an end of the control shaft which is rotatably supported by a plurality of bearings. A lubricating oil is supplied to the bearings so as to reduce nonuniformity in temperature distribution of the control shaft in the longitudinal direction.

摘要： A valve operating device that opens and closes a valve of an internal combustion engine by driving a valve stem in an axial direction includes a rocker cam that rocks in accordance with a rotation of a drive shaft and has a driving cam portion and a lift restricting cam portion; a cam follower that lifts the valve by contacting the driving cam portion slidingly; and a restricting member that prevents the cam follower from separating from the driving cam portion in cooperation with the lift restricting cam portion. A gap is formed between the restricting member and the rocker cam in a state where the cam follower is in contact with the driving cam portion and disappears such that the restricting member and the rocker cam come into contact with each other only when the cam follower separates from the driving cam portion.

摘要： In a crankshaft of an internal combustion engine wherein a crankthrow is shortened by the use of a multi-link mechanism, the crankthrow from the axis of a main journal to the axis of a crankpin is set shorter than one-half of a piston stroke, and an oil passage is formed to supply lubricating oil to a bearing portion of the crankpin. The pin-side opening of the oil passage, which is open at the outer peripheral surface of the crankpin, is formed in ranges other than angular ranges of 0°, 90°, 180°, and 270° with respect to a reference line extending from the axis of the main journal toward the axis of the crankpin in a decentering direction of the crankpin, thereby alleviating a stress concentration caused by a torsional torque in the vicinity of the pin-side opening of the oil passage.
