TECHNICAL INFORMATION
2.12.2 Catalyst
The catalyst is a device to lter exhaust gas
by means of its oxidation.
Internally, it is composed of hundreds of small
ducts that enable the passage of exhaust gas.
It contains precious metals (platinum,
palladium, iridium).
NOTE: The image is indicative only.
The installation of the catalyst must
be approved by KOHLER, for each
application.
Important
• In order to prevent breakage on the
connection ange, the catalyst must be
connected via a exible exhaust tube.
