摘要： An cylinder valve controlling apparatus comprises a first rocker arm and a second rocker arm cooperating with a middle lift cam and a low lift cam, respectively, to active two cylinder valves arranged for each of the engine cylinders, respectively. The apparatus further comprises a free rocker arm cooperating with a high lift cam. During engine operation at low speeds, the first rocker arm activates one of the cylinder valves in accordance with the profile of the middle lift cam, while the second rocker arm activates the other cylinder valve in accordance with the profile of the low lift cam. During engine operation at middle speeds, a coupling including a first lever establish drive connection between the first and second rocker arms and thus the first and second rocker arms follow the profile of the middle cam. During engine operation at high speeds, with the first-mentioned coupling maintaining the drive connection, another coupling establishes drive connection between the free cam follower and the first rocker arm. Thus, the first and second rocker arms activate the corresponding cylinder valves in accordance with the profile of the high lift cam.

摘要： An intake- and/or exhaust-valve timing control system for an internal combustion engine comprises a ring gear disposed between a rotating member having a driven connection with an engine crankshaft and a camshaft for changing a relative phase angle between the rotating member and the camshaft so as to control intake- and/or exhaust-valve timing of the engine depending on the operating state of the engine. The valve control system includes at least one pair of friction surfaces for creating friction torque between the rotating member and the camshaft so as to suppress a rapid change in relative rotational speed of the camshaft to the rotating member, and a spring for biasing one of the frictional surfaces to the other.

摘要： A valve control apparatus includes a variable mechanism configured to vary operating states of two intake valves by varying a swing range of a single swing cam; a primary swing arm configured to receive swinging force from the swing cam by becoming in contact with the swing cam, and configured to open/close one of the two intake valves; a secondary swing arm configured to open/close another of the two intake valves; and a connection changeover mechanism configured to connect/disconnect the primary swing arm with/from the secondary swing arm in accordance with an operating state of engine. The connection changeover mechanism disconnects the primary swing arm from the secondary swing arm to maintain the another of the two intake valves in a non-lifted state, when the variable mechanism controls a swing amount of the primary swing arm within a range below a predetermined amount. The connection changeover mechanism connects the primary swing arm with the secondary swing arm to open and close both of the two intake valves together, when the variable mechanism controls the swing amount of the primary swing arm within a range greater than or equal to the predetermined amount.
