Valvetronic system of the BMW N52 engine
The Valvetronic system is a BMW variable valve lift system[1] which, in combination with VANOS, allows infinite adjustment of the intake valve timing and lift.[2][3] The system claims to improve fuel economy and emissions, and negates the need for a throttle body in regular use.[4]
First introduced by BMW on the 316ti compact in 2001,[2] Valvetronic has since been added to many of BMW's engines.
