Abstract
A camshaft assembly for an internal combustion engine is provided. The camshaft assembly includes a first gear; a second gear; a hydraulically driven phasing assembly configured for varying the relative phasing of the second gear with respect to the first gear; and an idler shaft supporting the first gear. A method of constructing a camshaft assembly for an internal combustion engine is also provided. The method includes fixing a first gear and a second gear together via a hydraulically driven phasing assembly configured for varying the relative phasing of the second gear with respect to the first gear; and providing the first gear on an idler shaft.
