английский => русский Техника Автомобили / Автомеханика VVT-i system

This is a term used in the automative text about a VVT-i system in intake and exhaust camshafts. Can anybody assist me in translation of this term into Russian? Thanks in advance.

Here's the context:

The oil pressure sent from the advance or retard side path at the intake camshaft causes rotation in the VVT-i controller vane circumferential direction to vary the intake valve timing continuously.
