E.G.R. valve is mounted on heat exchanger end.
To ensure higher efficiency and longer durability to the valve,
the valve is cooled by engine coolant from heat exchanger.
Operation
Figure 58

E.D.C. 16 electronic central unit processes information from
atmospheric pressure sensor, water temperature sensor,
engine rpm sensor, accelerator pedal potentiometer and
drives modulator solenoid valve and throttle valve with
PWM signals, according to modes properly programmed in
its memory.
Modulator solenoid valve, whenever driven by E.D.C. 16
central unit, puts under-pressure power-assisted brake circuit
into communication with E.G.R. circuit. In E.G.R. circuit there
is set an under-pressure value depending on drive signal.
Such under-pressure acts on pneumatic valve E.G.R.
membrane calling and lifting the cut-off unit, which normally
shuts out exhaust gas passage towards intake.
In this way, exhaust gasses, through the heat exchanger, are
carried into throttle valve assembly chamber to be mixed to
air from intercooler and flowed into intake manifold.
During engine operation steps not requiring gas recirculation
(particulate filter regeneration, startup, cold engine, idling
rotation speed, load request, high elevation), the central unit
control signal to modulator solenoid valve is suppressed. The
solenoid
valve
closes
the
connection
between
power-assisted brake under-pressure circuit and E.G.R.
circuit, and simultaneously restores atmospheric pressure
into E.G.R. circuit.
The flow meter is a heated film type flow meter and is placed
between turbocharger and intercooler.
Inside the flow meter, sucked in air temperature sensor is
built in.
Operation
Operation principle is based on a heated membrane put in
between a measurement channel through which inlet air
entering the engine is flowing.
The heated film membrane is kept at constant temperature
(about 120
°
C, higher than incoming air temperature) by
heating resistance.
The air mass which runs through measurement channel
tends to take out heat from the membrane; therefore, to
keep the membrane at constant temperature, the current
must run through the resistance.
Absorbed current is proportional to air mass flowing to
engine; the current is measured by a Wheatstone bridge and
signal obtained is sent to the electronic central unit.

Air flow rate meter (flow meter)
Recirculated gas quantity regulation is through a mushroom
valve, pneumatically driven under under-pressure; the
under-pressure, through calibrated section fitting, is taken
from the tube connecting the vacuum unit to power-assisted
brake.
Driving under-pressure modulated by the solenoid valve and
overcoming the force exerted by counteracting spring (1),
will lift membrane (2), connected to cut-off unit (3), which
moves upwards and enables the recirculation of burnt out
gasses towards inlet manifold.

Modulator solenoid valve
Modulator solenoid valve is an integrating part in E.G.R.
system and power-assisted brake under-pressure tubes.
It is a proportional solenoid valve modulating E.G.R. valve
driving under-pressure depending on PWM signal generated
by EDC 16 central unit.
