Abstract: The invention relates to an internal-combustion engine with a hydraulic device (1) for rotation angle adjustment of a camshaft (3) relative to a crankshaft thereof, which is arranged on the drive-side end (2) of the camshaft (3) supported in several radial bearings (4) in the cylinder head (5) of the internal-combustion engine. The device essentially includes a drive unit (6) drivingly connected with the crankshaft and also of a driven unit (7) rotationally fixed to the camshaft (3). The drive unit (6) is in force-transfer connection with the driven unit (7) through at least two pressure chambers (12, 13), which are formed within the device (1) and which can be charged with a pressurized medium, wherein the pressurized medium is fed from one of the radial bearings (4) of the camshaft (3) and supplied to the pressure chambers (12, 13) of the device via first and second radial bore holes (14, 15) and via first and second axial channels (16, 17) in the camshaft (3), and also via first and second axial channels (19, 20) and via first and second radial bore holes (21, 22) into the driven unit (7). At least the first axial channels (16) formed as coaxial bore holes in the camshaft (3) and the first axial channels (19) in the driven unit (7) of the device (1) are connected to each other via a ring-shaped pressurized medium adapter (23) arranged between the end (18) of the camshaft (3) and the driven unit (7) of the device (1).

Abstract: A controller for controlling valve timing imbalance between cylinder groups of an engine. For each cylinder group, the controller has a variable mechanism for varying the valve timing. A lock mechanism locks the variable mechanism so as to maintain the valve timing of the cylinder group at a lock value. An ECU sets a valve timing target value based on the operating condition of the engine. The ECU and an oil control valve drive the variable mechanism. The ECU restricts the valve timing target value of at least one of the variable mechanisms of which operation is unlocked when the operation of at least one of the variable mechanisms is locked so that difference between the target value and the lock value decreases.

Abstract: In an oil flow control valve (OCV) according to the present invention, a first volume varying chamber is adapted to communicate with a second volume varying chamber through a second plunger breathing path, and the second volume varying chamber is adapted to communicate with a first breathing hole through an intra-plunger breathing path, an intra-shaft breathing path, and a third volume varying chamber. That is, the breathing path to the second volume varying chamber is long and the volume thereof is large, and the breathing path to the first volume varying chamber is still longer and larger in its volume. Consequently, the amount of foreign matters getting into the first and second volume varying chambers can be decreased and therefore it is possible to prevent the occurrence of an operation defect of the OCV.

Abstract: An engine includes an engine body that defines first and second banks arranged in a V-shape. A crankshaft extends within the engine body. First and second camshafts extend within the first bank, and third and fourth camshafts extend within the second bank. The first, second, third and fourth camshafts are generally disposed parallel to each other and parallel to the crankshaft. The first and third camshafts are placed next to each other. A first flexible transmitter surrounds the crankshaft and the first and third camshafts. The crankshaft drives the first and third camshafts through the first transmitter. A second flexible transmitter surrounds the second and fourth camshafts and either the first or third camshaft. The first or third camshaft drives the second and fourth camshafts through the second transmitter. The engine also includes VVT mechanisms to change an angular position of the camshafts relative to the crankshaft. The VVT mechanisms are disposed at the camshafts. Each VVT mechanism at least in part overlaps with either the first or second transmitter in a direction of an axis of the associated camshaft.

Abstract: A precontrol is carried out for the control of the position of the camshaft via a camshaft actuator especially in internal combustion engines and preferably in such engines of motor vehicles. For this purpose, a control for the position of a camshaft is carried out by a camshaft actuator with reference to a reference position in dependence upon the actual position of the camshaft and in dependence upon a determined desired position for the camshaft. An actuating signal for driving the actuator for the camshaft is determined from the desired position and the actual position of the camshaft actuator. In the determination of the actuating signal, a precontrol component is considered which is determined based on state quantities characterizing the operation of the camshaft actuator.
