The front engine cover must always be fitted when
checking and adjusting the valve timing or timing
belt tension, as the timing marks for both camshaft
pulleys are provided on its front end.
Correct timing belt tension is ensured by the
automatic timing belt tensioner.
No direction of movement is specified when using
a new timing belt. If, however, the old timing belt
is reused, the direction of movement must be
marked prior to removal.
Once the timing belt has been correctly tensioned,
the engine must be rotated by hand two turns
clockwise at the crankshaft in order to allow a subsequent check of the timing belt tension and
adjustment.
Cylinder block
The cylinder block consists of three parts. These
are the cylinder block, the lower crankcase and the
sump pan. The cylinder block has five cylinder
liners made of cast iron, which cannot be replaced.
The pistons are made of a homogeneous aluminum
alloy with a graphite coating on the sides. This
coating serves to reduce friction and dampen noise.
The pistons are cooled from below via oil-spray
nozzles screwed into the cylinder block.

Calculation of valve timing adjustment
angle
The 2.5L Duratec (VI5) engine has two camshaft
adjustment units which work independently of each
other.
One camshaft adjustment solenoid is installed for
each intake camshaft and exhaust camshaft.
This allows the PCM to continuously adjust the
intake and exhaust-side camshaft adjustments
independently of one another. The timing is
adjusted by the PCM using curves; adjustment is
primarily done as a function of engine load and
engine speed.
In this way the engine performance is increased
and internal exhaust gas recirculation is realized.
The advantages of camshaft adjustment are as
follows:
• Higher torque and improved torquecharacteristics
• Reduced fuel consumption
• Improved emissions performance
The camshaft adjustment solenoids are actuated
by the PWM by means of a PCM signal.
Continuous adjustment of the camshafts by the
PCM is achieved by means of the camshaft
adjustment solenoids, the camshaft adjustment
units and two CMP sensors. A defined quantity of
engine is oil is supplied to or drained from the
adjustment units via the camshaft adjustment
solenoids. The existing EOP (engine oil pressure)
is taken into account in the process. In this way
the valve timings are adjusted according to the
operating condition of the engine. The camshaft
adjusters work according to the vane-cell principle.
On starting the engine, both camshafts are
mechanically locked in their starting positions. The
intake camshaft is in the maximum late position
and the exhaust camshaft in the maximum early
position.
Control is divided into four main areas:
• Low engine speed and low load
• Partial load
• Low engine speed and high load
• High engine speed and high load
At low engine speed and low load, the exhaust
valves open early and the intake valves open late.
The result is reduced fuel consumption and more
uniform idling. In the partial load range, the exhaust valves and
the intake valves open late. The late opening of
the exhaust valves results in a good utilization of
the expanding gases in the cylinder. Closing the
exhaust valves after Top Dead Center allows
internal exhaust gas recirculation through aspiration
of exhaust gases into the combustion chamber.
Moreover, the intake valves close after Bottom
Dead Centre, allowing the fresh air/fuel mixture
and exhaust gases to flow back into the intake
tract. The result is reduced fuel consumption and
low emissions.
At low engine speed and high engine load, the
exhaust valves open late and the intake valves
open early. Due to the resulting valve opening
overlap at Top Dead Centre, the pulsating gas
column within the combustion chamber is utilized
to achieve better charging of the combustion
chamber. The result is increased torque at lower
RPM.
At high engine speeds and high engine load, the
exhaust valves open early and the intake valves
close late. Because a rapid gas exchange must be
achieved at high engine speeds, the early opening
of the exhaust valves achieves better expulsion of
the exhaust gas and the late closing of the intake
valves improves cylinder charge efficiency.
Optimum power output is achieved.
Many other camshaft positions are possible in
addition to these settings.
In order to avoid a malfunction in the camshaft
adjustment units at excessively low ambient or
engine-oil temperatures, they are activated by the
PCM with a time delay via the camshaft adjustment
solenoids. The PCM receives the information
required for this from the ECT sensor and the
outside air temperature sensor.
When idling and during deceleration, the camshaft
adjustment solenoids are activated repeatedly by
the PCM in order to remove any dirt which may be
on the bore holes and ring grooves.
Boost pressure control
Optimum regulation is achieved by means of an
electronically-controlled solenoid valve, the boost
control solenoid valve.
