System Operation
Turbocharger(s)
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.

If the throttle valve is closed quickly, the moving
air column hits the throttle valve. The air column
is reversed, flows back onto the rotating impeller
of the TC and powerfully decelerates it. A
recirculated air valve is installed to prevent this
deceleration of the impeller and thus allow the TC
to respond faster. The recirculated air valve is
controlled via a vacuum line which is connected to
the intake manifold. When the throttle valve is
suddenly closed, a high vacuum occurs in the
intake manifold. This opens the recirculated air
valve and the compressed air is returned to a point
before the compressor. This causes the speed of
the turbocharger to drop less rapidly and the boost
pressure can build up more rapidly when the
accelerator pedal is pressed again.

The wastegate control valve operates as a cycle
valve. The pressure acting on the membrane in
the boost pressure regulator is controlled by
appropriate pulsing of the wastegate control valve.
The pressure acting on the membrane in the boost
pressure regulator is reduced when the wastegate
control valve opens.
The operating voltage of the wastegate control
valve is 12V.
The internal resistance of the wastegate control
valve is 28.5 ± 1.5 Ohms.
The operating states are:
• De-energised: gate open between 1 and 3 – Boost pressure high > wastegate controlvalve closed > boost pressure regulator open
> turbine receives restricted exhaust gas
flow.
• Energised: gate open between 2 and 3 – Boost pressure low > wastegate control valveopen > boost pressure regulator closed >
turbine receives full exhaust gas flow.
