Three Way Catalytic Converter - Honda 1994 Civic Owner's Manual

Main Menu
The three way catalytic converter
contains platinum, palladium 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 re-
placement 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.

way catalytic converter inef-
fective.
