operations are very important and should
be carried out by qualified technicians with

CATALYTIC SILENCER

WARNING
Avoid parking the vehicle -catalytic version-
near dry brush wood or in places easily
accessible to children, as the catalytic
silencer becomes extremely hot during use;
be very careful and avoid any kind of contact
before it has completely cooled down.
The catalytic vehicle is fitted with a silencer
with metal catalytic converter of the "platinum-
rhodium bivalent" type.
This device provides for the oxidation of the
CO (carbon monoxide) and of the HC
(unburned hydrocarbons) contained in the
exhaust gases, changing them into carbon
dioxide and steam, respectively.
