ENGINE
TURBOCHARGER.
The
turbocharger
system
requires
little
attention
between
turbo
overhauls.
However,
it
is recommended
that
the
items
outlined
in the
Inspection
Report
of Section
III be
checked
during
required
inspection
ivtervals.
Should
trouble
occur,
refer
to
the
Troubleshooting
Table
in this
section
and
seek
out
the
possible
cause.
Do
not break
the
clamp
seal
joining
the turbine
and
compressor
units.

TURBOCHARGER
NOMENCLATURE.
Many
unfamiliar
terms
may
appear
on
the
following
pages
of
this
manual.
An
understanding
of
these
will be
helpful,
if
not
necessary,
in performing
maintenance
and
troubleshooting.
The
following
is a list
of
commonly
used
terms
and
names
as
applied
to
turbocharging.
TERM
MEANING
Supercharge
To
increase
the air
pressure
(density)
above
or higher
than
ambient
conditions.
Supercharger
A
device
that
accomplishes
the
increase
in
pressure.
Turbo-supercharger
More
commonly
referred
to
as a
"Turbocharger"
this
device
is
driven
by
a turbine.
The
turbine
is spun
by
energy
extracted
from
the engine
exhaust
gas.
Compressor
The portion
of
a turbocharger
that
takes
in
ambient
air and
compresses
it before
discharging
it to
the engine.
Turbine
The
exhaust
driven
end
of
the turbocharger
unit.
Wastegate
The
wastegate
is a butterfly
type
valve
in the
exhaust
by-pass
which,
throughout
its
travel
from
open
to
closed,
allows
varied
amounts
of
exhaust
pressure
to
by-pass
the
turbine,
controlling
its speed,
hence
the
output
of the
compression.
Ground
Boosted
or
These
phrases
indicate
that
the engine
depends
on
a certain
Ground
Turbocharged
amount
of
turbocharging
at
sea
level
to produce
the
advertised
horsepower.
An engine
that is
so designed
will
usually
include
a lower
compression
ratio
to
avoid
detonation.
Deck
Pressure
The
pressure
measured
in
the
area
downstream
of the
turbo
compressor
discharge
and upstream
of the engine
throttle
valve.
This
should
not
be
confused
with
manifold
pressure.
Manifold
Pressure
The
pressure
measured
downstream
of
the
engine
throttle
valve
and
is almost
directly
proportioned
to the
engine
power
output.
Normalizing
If
a turbocharger
system
is used
only
to
regain
power
losses
caused
by decreased
air pressure
of
high
altitude,
it is
considered
that
the engine
has been
"normalized."
