DESCRIPTION AND OPERATION
The complete engine is made of cast aluminum
which, when combined with the plastic intake
manifold, gives a very light unit.
2.OL Duratec-HE (M14) engine
Emission standard
N0TE:Due to the fine tolerance in the bearing
clearances and bearing shells, no service
operations whatsoever are permitted on the crank
assembly. In the event of damage, the complete
cylinder block and crank assembly must be
changed. European
Emissions Standard Stage
IV (Stage II I, depending
on country)
Further design features include a ladder frame
incorporating the main bearing caps which support
the crankshaft in the cylinder block, and the
deep-drawn side walls of the cylinder block which
reduce engine vibration.
The camshafts are driven by a pinned link chain
which runs very quietly and is also
maintenance-free.
