Secondary air
In order to reduce polluting emissions, the vehicle
is furnished with a catalytic converter in the muf-
fler.
To favour the catalytic process, an extra amount
of oxygen is added to the exhaust through a sec-
ondary air system (SAS).
This system allows more oxygen to be added to
the unburned gases before they reach the con-
verter, thus improving the action of the catalytic
converter.
The air enters the exhaust duct from the head, and
is purified by a black filter.
