Valvetronic
 | This article needs additional citations for verification. (July 2008) |
The Valvetronic system is a BMW 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
First introduced by BMW on the 316ti compact in 2001,[2] Valvetronic has since been added to many of BMW's engines. The first application of this technology in a turbocharged engine was the N55 engine.
