To clear difference among each, this is the simplest definition of each:
VVT-i has variable valve timing only on intake valves (accomplished through constant cam phasing).
Dual VVT-i has variable valve timing on both intake and exhaust valves (accomplished through constant cam phasing of both intake/exhaust).
VVTL-i has variable valve timing only on intake valves + variable cam lift on both intake and exhaust cams.

what's variable cam?
