Due to the catalytic reaction, the high tem-
perature reached by the exhaust gases
makes for the burning of the oil particles,
thus keeping the silencer clean and elimi-
nating the exhaust fumes.
To have the catalytic converter function
correctly and for long and to reduce possi-
ble problems regarding the soiling of the
thermal unit and of the exhaust, it is neces-
sary to avoid covering long distances with
the engine running at constantly low rpm.
It is sufficient to alternate these periods
with periods in which the engine runs at rel-
atively high rpm, even if only for a few sec-
onds, but rather frequently.

What has been stated above assumes par-
ticular importance for the cold starting of
the engine: in this case, in order to reach a
rpm regime sufficient to enable the ≈prim-
ing∆ of the catalytic reaction, just make
sure that the temperature of the thermal
unit has reached at least 50°C, which gen-
erally occurs a few seconds after starting
the engine.
!
CAUTION
Do not use leaded petrol, since it caus-
es the destruction of the catalytic con-
verter.
