VANOS

BMW’s system for adjusting camshaft timing relative to the crankshaft.

A little deeper

Changing cam timing changes when valves open and close. Double VANOS controls both intake and exhaust camshafts; it does not describe valve lift.

Also known as: double vanos · variable camshaft timing · VVT
