OPERATION: The
Air
Injection
Reactor system
is
designed
to reduce
air pollution caused
by
exhaust
emissions. It
is
entirely
separate
from the Positive
Crankcase Ventilating
system. The Air Injection
Reactor
system
operates by
oxidizing (or burning) the hydrocarbons
and
carbon mon-
oxide
as they are expelled from the combustion
chamber
into the
exhaust.
A positive displacement
air
pump,
driven
by the
engine, compresses
clean filtered air
which
is
distributed
and
injected
at
the exhaust port
of
each
cylin-
der. This
fresh air
mixes
with
the hot exhaust
gases and
promotes further
oxidation
(or
burning) of
both hydro-
carbons
and carbon
monoxidet
by
converting
some
of
them to
carbon dioxide and
water.
The
AIR
system
also
includes a special
calibrated
carburetor, distributor
and
related
components
.
MAINTENANCE: Complete effectiveness
of
this
system is
dependent on
proper
adjustment
of idle
speed, ignition
timing and
idle
fuel
mixture
being
set according
to
speci-
fications
as
indicated
on a
decal under the hood_ These
adjustments shou
ld be
checked
at the first oil
change
(4
months
or 6,000
miles,
whichever comes
first).
Subse-
quent
checks should
be made
at 12
month
or
12,000 mile
intervals,
whichever
comes first. These
adjustments are
also included
as
part of the quality tune-up recommended
at the
same intervals.
In
addition, all
hoses
and
fittings
should
be
inspected to make
sure
they
are
properly
con-
nected,
and
the drive belt inspected for
wear and
tension
on
the 12-month or 12,000-mile
schedule_
tNOTE: See carbon
monoxide
warning elsewhere in
this manual.
