VarioCam

VarioCam is an automobile variable valve timing technology developed by Porsche. VarioCam varies the timing of the intake valves by adjusting the tension on the timing chain connecting the intake and exhaust camshafts. VarioCam was first used on the 1992 3.0 L engine in the Porsche 968.

Porsche's more recent VarioCam Plus uses two sets of cam lobes 's to vary lift and siccor gear hydraulic phasing actuator to vary timing. This system debuted on 996 turbo.^[1]
