Engine- 2.5L Duratec (147kW/200PS) - VI5 » Engine (System Operation and Component Description).
System Operation

The variable camshaft timing occurs electro-hydraulically and individually for both camshafts.

The camshaft adjusters work according to the vane cell principle and have an adjustment range of 52 crank angle on the intake side and 47 crank angle on the exhaust side. On starting the engine and during idling, both camshafts are mechanically locked in their starting positions. The exhaust camshaft is in the early position and the intake camshaft is in the late position. The camshaft adjuster on the exhaust side has a torsion spring which compensates the camshaft drive torque.

This ensures that the assembly can return to the starting position under all operating conditions and when the engine is turned off.

Internal exhaust gas recirculation can be realized through continuous adjustment of the timings. This results in better fuel consumption and more favorable combustion temperatures which produce less pollutants. This means that pollutant level IV can be adhered to with a 3-way catalytic converter.

The variable timings also make it possible to optimize performance with wide open throttle.
