ABSTRACT:
A mechanism for controlling the duration of the opening of the intake valve of an internal combustion engine which includes a split cam having a first lobe which is fixed to a primary cam shaft that is drivingly connected to the engine's crankshaft and a second lobe which is freely mounted to the primary cam shaft and which is driven by gears of an auxiliary cam shaft which is axially shiftable, or a segment thereof shiftable, to rotate the second cam lobe relative to the first lobe of the split cam to thereby change the angular relationship between the first and second lobes to advance or retard the closing of the intake valve.
