Abstract: A camshaft adjuster (1) having a variable ratio gear unit (2). Usually, a drive movement of an electrical actuating assembly (7) is transmitted into a variable ratio gear unit (2) of a camshaft adjuster (1) on the side which faces away from the camshaft (6). According to the invention, the abovementioned drive movement is transmitted in from the side of the variable ratio gear unit (2) which faces the camshaft (6). As a result, a further assembly, for example a vacuum pump, can be driven by the variable ratio gear unit (2) on the side of the variable ratio gear unit (2) which has become free and faces away from the camshaft (6). An actuating shaft (4) of the actuating assembly (7) is preferably mounted via a bearing (34) which is supported on a circumferential face of the camshaft (6). This results in a reduced axial overall size of the camshaft adjuster and extended possibilities for the arrangement of an actuating assembly and the connection of additional assemblies.

Abstract: A camshaft phaser comprising a differential bevel gear arrangement to vary the phase relationship of a camshaft to a crankshaft in an internal combustion engine. In the differential gear system, a 45° beveled input gear is mounted parallel to and coaxial with a 45° beveled output gear. One or more 45° beveled spider gears is disposed in meshed relationship with the input and output gears in a gear pattern having a rectangular cross-sectional appearance. Rotation of the input gear causes an opposite rotation of the output gear. The phase relationship between the input and output gears may be varied by varying the position of the spider gear. The input gear and spider gears may be driven via a sprocket in time with the crankshaft in a plurality of arrangements.

Abstract: A valve timing control device includes a drive pulley driven by a crankshaft of an engine, and a driven camshaft. The camshaft has a cam that serves to open and close an intake port. An engine valve is spring-loaded by a valve spring, whereas the cam opens or closes the engine valve against the bias of the spring. Torque is transmittable between the drive pulley and the camshaft, and a rotation angle adjusting mechanism is provided therebetween. The rotation angle adjusting mechanism has a movable operating member being movable in a substantially radial direction.

Abstract: A variable valve timing mechanism 9 includes an electric motor 10 coupled to an intake camshaft 7. A plurality of rotation sensors 18 to 20 are located about the rotor 17 of the electric motor 10. Each of the sensors 18 to 20 outputs a signal corresponding to induced voltage generated by rotation of the rotor 17. Based on the signals form the rotation sensors 18 to 20, reverse rotation of an engine is detected. A counter C is decremented every time a crank signal is output after the occurrence of reverse rotation is detected. Further, a subtraction value Y is computed that corresponds to a discrepancy between the counter C and the actual crank angle caused by a discrepancy between the actual point in time of the occurrence of reverse rotation and the point in time of the detection of the reverse rotation. The counter C is reduced by the subtraction value Y. As a result, reverse direction of the engine is readily detected without providing a dedicated sensor, and the counter is reliably caused to correspond to the actual crank angle.

Abstract: A valve timing controller is provided with a first rotary element that rotates in response to a crankshaft, a second rotary element that rotates in response to a camshaft. Multiple link mechanisms are arranged adjacently in the rotational direction of the first rotary element to change a relative rotation phase between the first and second rotary elements. The link mechanism in each group is constituted by combining the first link linked to the first rotary element by a revolute pair with the second link linked to the second rotary element and the first link. The second link of the link mechanism in each group retains the first link of each of the link mechanisms in the same group and the other group in the rotational axis direction of the first rotary element between the second link and the first rotary element.

Abstract: In a system for controlling an engine having an input u, there are provided with applying means (vibration signal) for applying a component p that changes at a predetermined cycle to the plant, a Washout Filter for calculating a parameter h based on an output y of the plant, a finite interval integrator for integrating a value j obtained by multiplying the calculated parameter h by the applied component p in an interval of integral multiple of a cycle of the component p, and an infinite interval integrator, etc. for calculating the input u based on the integrated value g obtained by the integration. Owing to this configuration, it becomes possible to provide a system that can optimize the output y, while preventing the resonance of the control system.

Abstract: Rotary valve system for controlling communication with a port in an internal combustion engine which, in one disclosed embodiment, has a crankshaft, compression and expansion pistons connected to the crankshaft for reciprocating movement within compression and expansion chambers, a combustion chamber in which air from the compression chamber is combined with fuel and burned to produce an increased gas volume. The valve system has an outer valve member which is rotatively mounted in a bore and has an opening which moves into and out of communication with the port as the outer valve member rotates, an inner valve member rotatably mounted within the outer valve member with an opening at least partly overlapping the opening in the outer valve member, a flange extending along one edge of the opening in the inner valve member and through the opening in the outer valve member for sealing engagement with the wall of the bore, and means for effecting rotation of the valve members to change the degree of overlap between the openings and thereby control the timing and duration of communication between the openings and the port.
