OPERATION: The Controlled Combustion System is
entirely separate from the Positive Crankcase Ventilation
system and is designed to reduce exhaust air pollution by
altering the combustion process. CCS includes a special
air cleaner which
incorporates thermostatic control of
heated air to the carburetor, a special calibrated carbu-
retor and distributor and related components.
MAINTENANCE: Complete effectiveness of the system,
as well as full power and
performance, depend upon
engine idle speed, ignition timing, and idle fuel mixture
being set according to the specifications shown on a decal
under the hood. These adjustments should be checked
at the first oil change (4 months or 6,000 miles, whichever
comes first). Subsequent 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.
*System illustrated on V-8 engine, 6-cylinder system similar.
