Variable Valve Lift System: Notes

NOTE: Variable Valve Lift (VVL) system may also be referred to as Variable Valve Timing Lift Intelligent (VVTL-I or VVTL-i) system. This system is based on the VVT-i system. A cam changeover mechanism has been adopted in order to vary the extent of the lift of the intake and exhaust valves. As a result, it has achieved high power output during normal operation without affecting fuel economy or emission performance.
