Valvetronic

From Wikipedia, the free encyclopedia
Jump to: navigation, search

The Valvetronic system is a variable valve lift system[1] which, in combination with variable valve timing, allows infinite adjustment of the intake valve timing and duration.[2] The system claims to improve fuel economy and emissions, and negates the need for a throttle body in regular use.

History[edit]

First introduced by BMW on the 316ti compact in 2001,[2] Valvetronic has since been added to many of BMW's engines.
