Valve: Description and Operation

DESCRIPTION





Each of the four combustion chambers contains four valves, two intake and two exhaust, for a total of 16 valves. The intake valves (6) are opened by the variable valve actuation assembly. The exhaust valves (7) are opened directly by the camshaft through hydraulic bucket style cam followers. All valves use three bead lock keepers (1) to retain springs (3) and to promote valve rotation.
