Your Cl:
receives its power from
a
mixture of gasoline and air. The
air is taken into the system through
the air cleaner so it's important to
replace~he air cJea!1er at required
intervals. A dirty
air cleaner re
duces . engine efficiency.
Properly Tuned'Engine
Overall tuning (a check on tlin
ing , spark plugs, emission control
devices, etc;)
can improve your
car's gas mi,leage . You just
can't
expect an "out-of-tune" engine to
give you good gas mileage and
cleaner air.
Excess Weight
Fuel economy is related to the
work. the engine . must do. The
heavier the load , the more power it
take
s. Keep excess weight to a
minimum by removing any per
sonal effects or luggage from the
car or trunk when they are not
needed.
Tire Inflation
Underinfiation not only causes
needless wear of the tires, but
can
also waste gasoline. It's a good
idea to check tire pressures
regularly.
Wheel Alignment
Incorrect "toe in" or "toe out" can
have the effect,of dragging your
front tires sideways
and may cause
premature tire wear.
It takes power
to carry this extra load and that
takes gas from your tank.
Catalytic Converter
The catalytic converter is an
emi ssio n control device added to
5-22 the
exhaust system to reduce hy
drocarbon
and carbon monoxide
pollutants from the exhaust gas
stream. The converter contains
beads which are coated with a cata
lytic material containing platinum
and palladium.
Use of the catalytic converter
has the advantage
of allowing the
engine
to be re-tuned for improved
fuel economy anddriveability.
The catalytic converter requires
the use
of unleaded fuel only,
Unleaded gasoline is used to re
duce combustion chamber deposits,
corrosion
and to prevent lead con
tamination
of the catalyst that
would render it ineffective.
The use
of leaded fuel will cause the COIO- .
lytic converter to become ineffec
tive
as an emission control device.
