The three way catalytic converter
must operate at a high temperature
for the chemical reactions to take
place. It can set on fire any
combustible materials that come
near it. Park your vehicle away from
high grass, dry leaves, or other
flammables.
Keep the engine well maintained.
Have your vehicle diagnosed and
repaired if it is misfiring, back-
firing, stalling, or otherwise not
running properly.
The three way catalytic converters
contain precious metals that serve as
catalysts, promoting chemical
reactions to convert the exhaust
gasses without affecting the metals.
The catalytic converters are referred
to as three-way catalysts, since they
act on HC, CO, and NOx.
Replacement units must be original
Honda parts or their equivalent. A defective three way catalytic
converter contributes to air pollution,
and can impair your engine’s per-
formance. Follow these guidelines to
protect your vehicle’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 catalytic converter ineffective.
