Engine
The crankshaft
The crankshaft is identical to that used in the
2.8-litre V6 engine.
The crankshaft bearing caps are attached to
the central crankcase by 4 bolts.
•
The 4-bolt connection reduces the load on
the bearing caps considerably.
The middle two crankshaft bearing caps are
also bolted to the side of the crankcase.
•
The lateral bolted connection helps to
improve acoustics.
The pistons are forged to enable them to
withstand the high loads to which they are
subjected.
Due to the high combustion pressures, a 2-
material bearing shell is installed on the
connecting rod side. The bearing cap has a 3-
material bearing shell.
Advantage:
The bearing shell has a high load-bearing
capacity
