Three Way Catalytic Converter
The three way catalytic converter
contains precious metals that serve
as catalysts, promoting chemical
reactions to convert the exhaust
gasses without affecting the metals.
The catalytic converter is referred to
as a three-way catalyst, since it acts
on HC, CO, and NOx. A replacement
unit must be an original Acura part or
its equivalent.
The three way catalytic converter
must operate at a high temperature
for the chemical reactions to take
place. It can set on fire any combus-
tible materials that come near it. Park
your car away from high grass, dry
leaves, or other flammables.
THREE WAY CATALYTIC CONVERTER
A defective three way catalytic
converter contributes to air pollution,
and can impair your engine's per-
formance. Follow these guidelines to
protect your car's three way catalytic
converter.
Always use unleaded gasoline.
Even a small amount of leaded
gasoline can contaminate the
catalyst metals, making the three
way converter ineffective.
Keep the engine tuned-up.
Have your car diagnosed and
repaired if it is misfiring, backfir-
ing, stalling, or otherwise not
running properly.
