ABSTRACT:
An engine includes a camshaft with outer and inner elongate members. The outer elongate member can include a lobe that actuates a valve. The inner elongate member can be axially disposed within a passageway defined by the outer elongate member. The inner elongate member can be movable relative to the outer elongate member. A tab can be attached to the inner elongate member and can extend into an aperture defined by the outer elongate member. Crankshaft and camshaft pulleys can be respectively attached to the crankshaft and camshaft. A flexible transmitter can be routed over the camshaft pulley, a first deflection member, the crankshaft pulley, and a second deflection member. A first deflection actuator can be engaged with the first deflection member and can facilitate variation in a phase relationship between the camshaft and crankshaft pulleys. A vehicle may also be provided.
