    Abstract: The valve opening/closing timing control device includes: a driving rotating body; a driven rotating body; a fixed shaft portion; a fluid pressure chamber; a partitioning portion; and a phase control unit for controlling a rotation phase by supplying/discharging pressurized fluid to/from an advancing chamber or a retarding chamber via an inside of the fixed shaft portion. The driven rotating body has: an inner circumferential member with a cylindrical portion, and a coupling plate portion of the camshaft, the cylindrical portion and the coupling plate portion being integrated with each other; and an outer circumferential member provided with the partitioning portion. The outer circumferential member includes the inner circumferential member in a unified manner so as to have the same rotational axis. The inner circumferential member is formed with an iron-based material. The outer circumferential member is formed with a material that is lighter in weight than the iron-based material.

    Abstract: An engine accessory retards or advances one or more cam shafts of an engine relative to the crankshaft during engine operation. The accessory acts upon the timing chain that engages wheels on cam shafts and crankshaft. The accessory includes a rod translatably mounted to the engine, wherein a hydraulic cylinder or an electric motor translates the rod in accordance with signals from an electronic controller. The signals from the controller are in response to values of selected variables related to engine condition or are in response to manual input. Chain engagement wheels are journalled on either end of the rod. One chain engagement wheel mates with the part of the timing chain approaching the crankshaft wheel. The other chain engagement wheel mates with the part the chain travelling away from the crankshaft wheel. Translation of the rod affects the chain length between the crankshaft wheel and the camshaft wheels which are driven by the crankshaft wheel, whereby the rod's translation retards or advances the cam shafts relative to the crankshaft.

    Abstract: A variable camshaft drive system for an internal combustion engine includes a primary camshaft phaser interposed between the engine crankshaft and a first camshaft. A secondary camshaft phaser determines the phase relationship between the first camshaft and a second camshaft driven by the first camshaft and which is located on the same bank of cylinders as the first camshaft. The operation of each phaser is controlled by an electronic controller which samples one or more engine operating parameters.

    Abstract: A system for controlling the timing of poppet-type intake and/or exhaust valves in internal combustion engines of the four-cycle spark or compression ignition and two-cycle compression ignition type that may be normally aspirated, supercharged or turbocharged, wherein the timing is adjusted automatically or manually in relation to the speed of the engine to obtain optimum efficiency at any given speed. Dual camshafts are utilized, one for opening the valves, and one for closing the valves. An adjustable timing mechanism between the crankshaft and the camshafts simultaneously adjusts the opening and closing cycles of the valves.
