Abstract: An engine variable valve actuation mechanism that substantially equally adjusts the valve lift amount in each cylinder. The mechanism includes variable valve lift mechanisms respectively arranged in association with the engine cylinders. A control shaft extends through the variable valve lift mechanisms. An actuator moves the control shaft in the axial direction and drives the variable valve lift mechanisms. Collars are arranged alternately with the variable valve lift mechanisms. Each collar includes a cylindrical sleeve and flanges formed integrally with the sleeve. The flanges directly or indirectly contact the end faces of adjacent variable valve lift mechanisms. This determines the positions of the variable valve lift mechanisms with respect to one another in the axial direction.

Abstract: A valve drive (1) of an internal combustion engine which is used to actuate a gas exchange valve (6) is provided. Displacement of the valve takes place when a cam (9) is lifted and when a hydraulic force applying device (12) is lifted. A piston (13) of the force applying device can be displaced from a first end position (A) to a second end position by feeding a hydraulic medium, which can be pressure-adjusted, from a hydraulic medium line (24) into a pressure chamber (21). The pressure chamber (21) can be connected to the hydraulic medium line (24) via a shut-off element (20) which is open towards the pressure chamber (21) and which is arranged in the housing (15) and also by means of at least one passage (26) in the housing (15). The passage (26) is at least partially blocked by an external casing surface (16) of the piston (13) in the first end position (A) thereof.

Abstract: A valve control system includes a vehicle control module that generates a lift mode command signal to transition one of intake and exhaust valves between N open lift modes. A time module generates a response time signal that indicates a duration of the transition and a lift limit signal that disables the transition. The time module generates the response time and lift limit signals based on current lift mode and status signals. The current lift mode signal indicates a current lift state of one of the intake and exhaust valves. The status signal indicates status of a lift control valve. The lift control valve actuates one of the intake valve and the exhaust valve. The event module generates the current lift mode and status signals based on the lift command signal, the response time signal, and the lift limit signal. One of the time and event modules enables the transition.

Abstract: In an internal combustion engine, an actuator for driving a control shaft of a variable valve-operating mechanism is disposed in a space surrounded by a cylinder head having a plurality of intake ports, an intake manifold having a plurality of branch pipes connected to the intake ports, and a throttle body disposed at one end in a direction of arrangement of the branch pipes. Thus, the actuator can be disposed by effectively utilizing such an unused space surrounded by the cylinder head, the intake manifold and the throttle body, thereby reducing the entire length and the entire height of the internal combustion engine including the actuator.

Abstract: A variable valve drive (1) of an internal combustion engine is provided which is used to actuate a gas exchange valve (5). Displacement thereof takes place via a cam (7) generated lift and via a lift generated by a piston (14, 32) of a hydraulic force applying device (4a, 4b), which is superimposed on the cam lift and which is independent thereof. The hydraulic force applying device is connected to a hydraulic fluid line (S-P) which provides an adjustable hydraulic pressure medium and includes a pressure chamber (24a, 24b) which is limited on one side by the piston (14, 32), in addition to a hydraulic valve lash compensation device (23a, 23b) which includes a working chamber (22a, 22b) which is radially defined by a housing (13a, 13b). The housing (13a, 13b) is also used to radially define the pressure chamber (24a, 24b).
