boost steady or reduce it as needed. By reading the
manifold pressure sensor, the ECU can adjust turbine
inlet pressure (Geometry of Vanes) instantaneously to
control boost at any speed/ load and to limit boost at
full load.
Advantages / Features
l
Good low end torque
l
Good transient response
l
Good fuel economy
l
Increased useful engine operating range.
l
It provides more matching level of pressure boost
even to a slow spinning turbine without providing
too much of a boost at higher speed.
l
VNT is electronically controlled and pneumatically
actuated.
l
When the vanes of the TC are closed, the engine
will have a higher exhaust back pressure and
create more heat which will in turn warm the
engine faster in cold ambient conditions.
l
Low engine noise
l
Lower emission
Inter Cooler
(Fig. 213)
The intercooler further increases the power of the
engine by cooling the pressurized air coming out of
the compressor before it goes into the engine. This
means that if the turbocharger is operating at a boost
of 7 psi, the intercooler system will put in 7 psi of
cooler air, which is denser and contains more air
molecules than warmer air.

Instructions duringReception and Inspection
l
Ensure that there are no damages to packaging,
if the packaging is damaged, check the
appearance of turbochargers and the parts or
components making up the turbocharger. Amore
in-depth inspection is recommended for the most
sensitive components such as actuator and comp
housing.
l
Containers must be unloaded in conditions that
do not expose the system to bad weather (do not
unload and store even momentarily in rain,..).
Otherwise, oxidation / corrosion may well occur
very rapidly)
l
If a packaging tray is dropped with turbochargers
in it during logistics operations, the batch of
