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： A low speed cam is disposed on a cam shaft. A low speed sub-rocker arm actuated by the low speed cam is pivotally connected to a main rocker arm. A connecting member is supported by the main rocker arm. The connecting member has both a first condition wherein the sub-rocker arm and the main rocker arm are fixed to each other to constitute a single unit and a second condition wherein the sub-rocker arm and the main rocker arm are disengaged from each other. A hydraulically actuating mechanism has a hydraulic work chamber. The mechanism induces the first condition of the connecting member upon discharge of hydraulic fluid from the work chamber and induces the second condition upon feeding of hydraulic fluid to the work chamber. A control unit causes the hydraulically actuating mechanism to induce the first condition of the connecting member when the engine stops.

摘要： A variable valve actuation apparatus of an internal combustion engine has a multinodular-link motion converter, to vary at least a working angle. A position of rotation of a control shaft, variably adjusting the attitude of the motion converter, is set, so that, at a peak lift during a valve opening period, an angle γ2 between an extension line of a line segment connecting a first fulcrum corresponding to a drive-eccentric-cam center and a second fulcrum provided on a rocker arm and a line segment connecting the second fulcrum and a third fulcrum provided on the rocker arm at a position different from the second fulcrum at a middle working-angle control mode is less than both an angle γ1 between the two line segments at a minimum working-angle control mode and an angle γ3 between the two line segments at a maximum working-angle control mode.

摘要： A valve timing adjusting system includes mutually parallel axial fluid paths both formed about a fastening bolt which engages with an axial bore formed at the end of a camshaft. One of the axial paths if formed through the fastening bolt and the other axial path is formed between the outer periphery of the fastening bolt and the inner periphery of the axial bore of the camshaft. This avoids necessity of formation of axial fluid path through the camshaft and thus redudes mashing step in production line to lead lower cost.
