Description
1 Camshaft bearing cap
2 Camshaft
3 Reference cam
4 Roller finger cam follower
5 Hydraulic lash adjuster
6 Cylinder head
The five bearing camshaft runs directly in the
aluminum cylinder head.
An additional reference cam is provided for the
camshaft position (CMP) sensor.
The cam followers are supported across the
hydraulic lash adjusters and valves and the
camshaft operates the cam followers through
their roller bearings.
This has the advantage of lowering friction and
therefore increasing durability.
