摘要： The adjustment device for continuously adjusting an angular orientation of a camshaft of an internal combustion engine relative in relation to a drive wheel of the engine, has a servomotor including a rotary piston nonrotatably attached to the camshaft and a plurality of adjusting segments between the rotary piston and the drive wheel equally spaced around the outer peripheral surface of the rotary piston and alternately attached to the rotary piston and the drive wheel so as to form a plurality of volume-adjustable working chambers connectable in pairs in operation; a pump located in the drive wheel and connected with the servomotor to receive an adjustably pressurized medium and to feed the adjustably pressurized medium to the servomotor means; a first control valve device connected to the pump for controlling supply of the adjustably pressurized medium to the pump to activate and deactivated the pump; and a second control valve device connected to the working chambers to select working chamber pairs and to connect the working chambers of the selected working chamber pairs to provide a flow of pressurized medium between those working chambers and thus to adjust the angular orientation of the camshaft relative to the drive element. Advantageously four pair of working chambers are provided including a third and fourth pair arranged diametrically opposed to each other on opposite sides of the rotary piston.

摘要： A variable valve timing control device includes a valve unit including a spool having a plurality of land portions at an outer circumference of the spool, and being formed with a drain flow path inside the spool. The valve unit allows a second pump port and a lock port to communicate with each other in a case where the spool is set at an unlock position where a lock state of a lock mechanism is released, and the valve unit closes the second pump port with the land portion of the spool and allows the lock port to communicate with the drain flow path in a case where the spool is set at a lock position where the lock mechanism is allowed to be shifted in the lock state.

摘要： Methods and systems are described for an engine with a cam torque actuated variable cam timing phaser. Phaser positioning control is improved by reducing inaccuracies resulting from inadvertent spool valve and/or phaser movement when the spool valve is commanded between regions. In addition, improved spool valve mapping is used to render phaser commands more consistent and robust.

摘要： A valve opening and closing timing control apparatus includes a drive-side rotational member, a driven-side rotational member, an intermediate member abutting the driven-side rotational member, a mounting member connecting the driven-side rotational member and the intermediate member to the camshaft in a state being mounted at the camshaft, and a control valve mechanism arranged with a same axis as a rotation axis of the drive-side rotational member. The intermediate member includes an inner peripheral surface in contact with the outer peripheral surface of the mounting member. The flow passage includes an outlet flow passage provided at the intermediate member and positioned along a radial direction for sending out a fluid which is supplied to an inner peripheral surface of the intermediate member to an advanced angle chamber or a retarded angle chamber provided between the drive-side rotational member and the driven-side rotational member.

摘要： A valve opening/closing timing control device includes a driving rotary body rotatable in synchronism with a crankshaft of an internal combustion engine, a driven rotary body rotatable in unison with a cam shaft of the internal combustion engine and rotatable also relative to the driving rotary body within this driving rotary body, a fluid pressure chamber formed by the driving rotary body and the driven rotary body, and a partitioning portion that partitions the fluid pressure chamber into an advance chamber and a retard chamber. The driving rotary body includes an aluminum housing having a pulley that receives a drive force of the crankshaft via a drive belt and a plate attached to at least one face of the housing. Between the housing and the plate, there is provided a gap allowing outflow of fluid.

摘要： A method for controlling continuously variable valve timing (CVVT), may include determining whether a CVVT control is started, detecting a position of a cam and a position of a crankshaft when the CVVT control is started, determining whether the cam is positioned at a locking position based on the positions of the cam and crankshaft, determining whether the cam is controlled to be positioned from the locking position to an advancing position or a holding position, when the cam is positioned at the locking position, and when the cam is controlled to be positioned from the locking position to the advancing position or the holding position and when a condition for performing the CVVT control is satisfied, determining whether a cam torque is negative and performing predetermined CVVT control after waiting a predetermined time when the cam torque is negative.
