Valve gear: Notes

The valve gear consists of the fully variable valve lift timing 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 placed 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 freely definable.
