USE OF MATERIALS THAT DO NOT HARM THE ENVIRONMENT
None of the car’s components contain asbestos. Padding and the air conditioning system do not contain CFCs (Chlo-
rofluorocarbides), the gases considered responsible for the destruction of the ozone layer. None of the colourings and
anti-corrosion coatings of the nuts and bolts contain air- or water-table-polluting cadmium or chromates, but envi-
ronmentally-friendly substances.
DEVICES FOR REDUCING EMISSIONS (petrol engines)
Three-way catalytic converter (catalytic exhaust pipe)
The exhaust system is equipped with a catalyst made up of noble metal alloys; it is housed in a stainless steel container
capable of withstanding the very high operating temperatures.
The catalyst converts the unburnt hydrocarbons, the carbon monoxide and the nitric oxides found in the exhaust gases
(though in small amounts, thanks to the electronic-injection ignition systems) into non-polluting substances.
When functioning normally, the catalytic converter reaches high temperatures. For this reason do not park the car over
inflammable material (e.g. paper, fuel oil, grass, dead leaves, etc.).
Lambda sensors
The Lambda sensors detect the oxygen content in the exhaust gas. The signal sent by the oxygen sensor is used by the
injection system electronic control unit to constantly mix air and fuel in the correct proportion.
Evaporation control system
As it is impossible to stop the build-up of petrol fumes, also when the engine is not running, the system traps them in
a special container holding active carbon.
The fumes are sucked in from here and burnt while the engine is running.
