Three Way Catalytic Converter - Honda Prelude 2003 Owner's Manual

The three way catalytic converter
contains platinum and rhodium.
These metals 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 flamma-
bles.

A defective three way catalytic
converter contributes to air
pollution, and can impair your
engine's performance. 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 catalytic converter inef-
fective.
