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
50
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 specifica.ions 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.
