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 Honda 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 com-
bustible materials that come near it.
Park your car away from high grass,
dry leaves, or other flammables.
Always use unleaded petrol. Even
a small amount of leaded petrol
can contaminate the catalyst
metals, making the three way
catalytic converter ineffective.
Keep the engine tuned-up.
Have your car diagnosed and
repaired if it is misfiring, back-
firing, stalling, or otherwise not
running properly.
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.
