Valve gear (Ver.1): Notes
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 BMW X3, 2016 BMW X3, 2015 BMW X3, 2014 BMW X3, and 2013 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.
The valve gear consists of the fully variable valve lift timing (Valvetronic) and the variable camshaft timing control (double VANOS), which enables a free choice of closing time for the intake valve. Valve lift timing only takes place on the intake side; camshaft control takes place on the intake and exhaust side.
Throttle-free load control is only possible if the following variables can be controlled:
- Valve lift of the intake valve
- Camshaft adjustment of the intake and exhaust camshafts.
Result: The opening period of the intake valve is variable.
