OPERATION: The Air Injection Reactor system,
(used on vehicles not equipped with
CCS)
is
de-
signed to reduce air pollution by oxidizing (burning)
the hydrocarbons and carbon monoxide after they
45
leave the combustion chamber. A positive displace-
ment air pump, driven by the engine, compresses
filtered air which
is
injected at the exhaust port of
each cylinder. This air mixes with the exhaust gases
and promotes further oxidation of both hydro-
carbons and carbon monoxide. The
AIR
system also
includes a specially calibrated carburetor and dis-
tributor.
MAINTENANCE: Complete effectiveness of this
system
is
dependent
on
the engine idle speed,
ignition timing and
dwell being set according
to
specifications
as
indicated
on
a label under
the
hood.
These
adjustments
should
be
checked at the first oil change (4 months or
6,000 miles, whichever comes first). Subse-
quent checks should be made at 12 months 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 connected, and the drive belt in-
spected for wear
and
tension
on
the
12
month
or
12,000 mile schedule.
