Beschreibung
Zusammenfassung:	It is provided a method for actuating engine valves, in particular to be used to produce engine braking and brake gas recirculation BGR. The method for selectively actuating engine valves comprising the steps of: disabling main exhaust and intake valve events (923, 932); providing for engine braking two compression release valve events (920) and at least one brake gas recirculation events (922, 924) for an exhaust valve, and providing for engine braking at least one intake valve event (930) for an intake valve for engine braking, whereby a 1.5-cycle compression release engine braking or a full two-cycle compression release engine braking is provided; and reinstituting the main exhaust and intake valve events (923, 932) for positive power operation while disabling at least the compression release valve events (920) and the intake valve events (930).
