    Abstract: A valve timing gear of an internal-combustion engine is provided, in the case of which a camshaft acts by a timing cam upon a valve by way of a tappet whose cam-side contact path can be changed by a control device for changing the valve opening period. For achieving a small-sized control device, this control device comprises a slider rocker guided in the valve lifting direction by way of a first sliding hinge joint arranged on an engine section side and an additional sliding hinge joint provided on the tilting segment side, with a control opening penetrated with play by a timing-cam-free section of the camshaft. An element, which can be operated in a controlled manner, of an adjusting device is arranged in/on the camshaft, while rotating with it, and being applied such to the circumference of the control opening that the adjustable slider rocker, while the camshaft is rotating, carries out for each valve lift a periodic rocking movement which is used for forcibly controlling the tilting segment.

    Abstract: A variable valve mechanism using a non-uniform coupling in an internal combustion engine is equipped with an axis-supporting member for supporting a cam-side rotation axis in an eccentric state. In the variable valve mechanism, the axis-supporting member is driven while taking account of friction occurring in the axis-supporting member by changing the position of the axis-supporting member so as to align with the direction of a dragging torque generated between the axis-supporting member and an intermediate rotating member or between the axis-supporting member and a rotation axis member.

The system also includes an intake valve gear for the intake valve which incorporates an intake variable valve timing mechanism. A control unit operates responsive to a low-speed/low-load operating range of the engine and a low-speed/high-load operating range of the engine to condition the exhaust variable valve timing mechanism for providing advanced opening and closing timings of the exhaust valve to cause a reduced valve overlap between the intake and exhaust valves, and at the same time condition the intake variable valve timing mechanism for decreasing an opening duration of the intake valve to provide a retarded opening timing thereof after a top dead center and an advanced closing timing thereof. The control unit operates responsive to a low-speed/medium-load operating range of the engine to condition the exhaust variable valve timing mechanism for providing retarded opening and closing timings of the exhaust valve to cause an increased valve overlap between the intake and exhaust valves, and at the same time condition the intake variable valve timing mechanism for increasing the opening duration of the intake valve to provide an advanced opening timing thereof before the top dead center and a retarded closing timing thereof.

    Abstract: An object of the present invention is to obtain a controller device for a variable valve timing apparatus capable of controlling a phase to an arbitrary fixed valve timing from immediately before an internal combustion engine stops until after the internal combustion engine has stopped. The controller device for the variable valve timing apparatus according to the present invention performs, during engine stop processing of the internal combustion engine, normal control of changing the relative rotational phase of a camshaft to a most advanced position or a most retarded position when the rotational speed of a crankshaft is equal to or more than a first threshold, and low-speed control of fixing a current or a voltage supplied to the motor to be constant to maintain the relative rotational phase of the camshaft at the most advanced position or the most retarded position in a period from when the rotational speed of the crankshaft is lower than the first threshold until the rotational speed becomes zero.
