The last bit of Tripower technology is the intake valve lift control.

The invention relates to a control device for an engine able to control at least one of an intake valve and an exhaust valve via a driving mechanism actuated without a torque from an output shaft of the engine, and a transmission connected to the engine.

N.E.V.I.S. stays for New Exhaust Valve and Intake System.
