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