Turbocharger – Overview
Turbocharger(s)
CAUTION: Do not switch off the engine
while it is running at high speed. If the
engine is switched off while it is running
at high speed, the turbocharger will
continue to run after the engine oil
pressure has already dropped to zero. This
will cause premature wear in the
turbocharger bearings.
A TC consists of an exhaust turbine located in the
exhaust gas flow, this turbine is connected to a
compressor by a shaft. The turbine is made to
rotate by the exhaust gas flow from the engine and
thus drives the compressor. The compressor
increases the pressure in the engine intake tract
so that a greater mass of air enters the cylinder
during the intake stroke.
The turbine housing of the TC is integrated into the
exhaust manifold. This construction offers
thermodynamic advantages compared with the
usual construction, the maximum exhaust
temperature is up to 1050°C.
The maximum boost pressure is 0.65 bar.
The exhaust manifold is secured to the exhaust
side of the cylinder head with 12 self-locking nuts.
The exhaust manifold gasket is a multi-layer steel
gasket and cannot be reused. In order to
compensate for the thermal expansion of the
exhaust manifold, the flange of the TC is provided
with two grooves.
The TC and the exhaust manifold are joined by a
hose clip. The hose clip must not be loosened or
removed. The TC and the exhaust manifold are
not available as separate replacement parts,
exchange is only possible as a complete unit.
The turbocharger heat shield is secured to the
exhaust manifold by four bolts. Two of the bolts
have spring washers underneath their heads.
During removal, make a note of the installation
location of the spring washers to refer to during
installation.
The recirculated air valve is built into the TC
housing and cannot be changed.
The Ford diagnostic unit can test the operation of
the wastegate control valve using actuator
diagnosis.
The boost pressure regulator is set in the factory.
Adjustments to the boost pressure regulator must never be attempted. A red colored seal is applied
to the adjustment nut of the operating rod, in order
to monitor the factory setting of the boost pressure.
The bearings of the TC are lubricated with engine
oil. The engine oil passes from the cylinder block
through the oil supply pipe to the TC. The oil is
returned to the oil pan through the oil return pipe,
The TC is cooled by the engine coolant circuit.
When installing hoses and lines, make certain that
their ends are free of oil residues and dirt.

The TC consists of a turbine and a compressor.
The turbine is driven by the exhaust gas flow. A
common shaft drives the compressor and this then
compresses the intake air.

The size of the TC is designed to produce a charge
effect even at medium engine speeds and lower
exhaust gas flows. This means that, when the engine speed is high and there is a large amount
of exhaust gas, either the boost pressure of the
TC will become too high or its speed will be too
high. The TC must therefore be regulated. The
best regulation is achieved by an electronically
controlled wastegate control valve. The wastegate
control valve controls the pressure on the
membrane in the boost pressure regulator.
The wastegate control valve is actuated by the
PCM with a PWM signal according to a map. The
boost pressure is applied to the wastegate control
valve via the pressure line from the compressor.
This pressure is passed to the boost pressure
regulator via the wastegate control valve. This
opens the bypass valve using a linkage. This
channels a portion of the exhaust gases around
the turbine. If the wastegate control valve is
actuated by the PCM, a bypass is opened in the
wastegate control valve. This causes the pressure
which can act on the membrane in the boost
pressure regulator to be reduced. This occurs until
the boost pressure has reached a set value. By
actuation with a PWM signal, it is also possible to
partially open or close the wastegate control valve.
This results in a constant boost pressure and
therefore high torque over a wide range of engine
speeds.
Because the PCM calculates the boost pressure
using the signal from the boost pressure sensor
and the IAT (intake air temperature) sensor, the
atmospheric pressure and the temperature are
automatically compensated for. Because of this
compensation, the engine power is not noticeably
affected by variations in atmospheric temperature
or pressure.
