BACKGROUND INFORMATION: During the
combustion
process in an automotive engine, certain hydrocarbons in
the fuel fail to burn completely and are discharged into
the
engine crankcase or exhaust system. Some carbon mon-
oxide is also
formed during
the combustion process.
This
is also discharged into
the
exhaust system. On a per·car
basis, concentrations of
these
combustion
products
are
insignificant. Multiplied
by millions
of vehicles,
however,
crankcase and exhaust emissions combine with pollution
products from
other
sources to
contribute to
the total
air
pollution problem
.
General
Motors
has,
since
the late 1940's,
been a
leader
in research
and
development
work related
to
vehicle
emissions, and control systems
have been
developed
which are
highly
effective
in reducing undesirable
crank·
case and exhaust
emissions. This
work continues at an
accelerated pace.
All
new 1969
Chevrolet passenger cars and
light
duty
trucks comply with all
Federal
and State
laws
and
regula·
tions for
the
Control of Air Pollution from
New
Motor
Vehicles and New Motor Vehicle
Engines.
YOUR ROLE IN CONTROLLING AIR POLLUTION:
It is
very important
that the
engine in your Chevrolet vehicle
be serviced regularly in order to maintain
its
efficiency
and minimize emissions in
normal
driving.
The following
pages
describe
the crankcase and exhaust
emission control systems on Chevrolet vehicles, and pro-
vide information on their
proper
maintenance. By following
these recommended
maintenance services you will help
assure cleaner air and will provide a better running,
longer
lasting engine for greater all·around satisfaction, economy
and performance.
