The Engine Control Module (ECM) can adapt the instantaneous load- and RPM- situation by adjusting the timing.
To do so, the total of four valves for camshaft adjustment allow more or less oil pressure to impact the mechanical adjustment mechanism.
While the exhaust camshafts only have control over a single stage adjustment, intake camshafts can be adjusted variably.
