摘要： Each cylinder is provided with a first intake valve and a second intake valve, and a first intake cam for driving the first intake valve and a second intake cam for driving the second intake valve are coaxially pivotally supported on an intake camshaft. A first cam phase change mechanism which varies respective phases of the first and second intake cams relative to a crankshaft of the internal combustion engine is combined with a second cam phase change mechanism which varies a phase of the second intake cam relative to the first intake cam. The second cam phase change mechanism is set to have a variable-phase angular range wider than that of the first cam phase change mechanism.

摘要： A valve drive for activation of gas exchange valves of internal combustion engines, with which valve stroke switching is accomplished with little effort, a low construction height, and at low switching forces. Incorrect switching and damage to the camshaft during valve stroke switching are avoided, even at high engine speeds of rotation. An adjustment shaft that is rotatable by the camshaft and parallel to the camshaft has two adjustment devices rotatably disposed on it, along with two tappets between the adjustment devices. The tappets are connected with a shift gate for valve switching between two different cam profiles of a cam package that is axially displaceable on the camshaft. The tappets each have a contour that contacts the adjustment devices via a guide pin. A gear wheel engages with a gear segment on the camshaft, via a drive on the adjustment shaft, to rotate the adjustment shaft.

摘要： A hydraulic control system to provide an oil or pressurized fluid supply to a variable cam phasing system in an engine is provided. The hydraulic control system includes a valve housing attachable to a front cover assembly of the engine; a first valve installed in the housing; and an inlet passage defined by the front cover assembly hydraulically communicating with the first valve in the housing to carry pressurized fluid from a fluid source to the first valve. A first and a second outlet passage defined by the housing hydraulically communicates with the first valve to allow the pressurized fluid to flow to the cam phasing system, thereby variably moving a camshaft assembly operatively connected to the cam phasing system.
