Variable cam timing

[Paul Beam]

Based upon Ed's explanation, it seems to me that what is needed is a
magnetic coupler or clutch on both the crank and and cam(s).  Under computer
control, you could allow the cam or the crank to slip momentarily thus
changing the phase of the cam.  With a DOHC, you could completely adjust the
phase of both the intake and exhaust.  

Just an observation from a dumb EE.
