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.

Mechanical tappets are fitted without adjusting
shims.
Due to the special materials and the optimized
camshaft profiles, the wear in the area of the valve
gear is so minute that checking and adjustment of
the valve clearances is only necessary after the
engine has been in extensive service.
Different sizes of replacement valve tappets are

The camshafts are driven by a low-noise,
maintenance-free pinned link timing chain.
The timing chain is lubricated by the engine oil
circuit.
An elongated timing chain guide and a timing chain
tensioner arm ensure optimum timing chain
guidance and silent running.
The timing chain is tensioned by a hydraulic timing
chain tensioner which is supplied from the engine

oil circuit.
The timing chain tensioner can be used again after
removal.
The camshaft drive requires no maintenance.

A rotor oil pump is used for engine lubrication.
The rotor oil pump is a positive displacement pump
with an internally toothed outer rotor and an
externally toothed inner rotor.
The rotor pump works very evenly, can produce
high pressures and is therefore fundamental for
optimum engine lubrication.
