Sebring Convertible V6-2.7L VIN R (2003)
Valve: Description and Operation
INTAKE/EXHAUST VALVES & SEATS
DESCRIPTION
The valves are made of heat resistant steel, and have chrome plated stems to prevent scuffing (Fig. 15). The four valves per cylinder (two intake and
two exhaust) are actuated by roller rocker arms, which pivot on stationary lash adjusters. All valves use three bead lock keepers to retain springs and
to promote valve rotation.
OPERATION
The intake valve allows the air/fuel mixture to enter the combustion chamber. The exhaust valve allows the burned air/fuel mixture to exit the
combustion chamber. Also, the intake and exhaust valves seal the combustion chamber during the compression and power strokes.
