2007 Lancia Musa catalytic converter

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
(Chlorofluorocarbides), 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 environmentally-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.

DEVICES FOR REDUCING EMISSIONS (Multijet engine)
Oxidising catalytic converter
This device converts the polluting substances in the exhaust gas (carbon monoxide, unburnt hydrocarbons and
particulates) into harmless substances, thus reducing the smokiness and smell associated with diesel engine
exhaust fumes.
The catalytic converter consists of a stainless steel case containing a honeycomb ceramic core in which there is the
precious metal that carries out the catalysing action.
Exhaust Gas Recirculation (E.G.R.) system
This system recirculates or reuses part of the exhaust gas in a proportion which varies according to engine
operating conditions.
When necessary, it is used for the control of nitrogen oxide emissions.

PROTECTING THE ENVIRONMENT
The devices for curtailing petrol engine emissions are the following:
❒three-way catalytic converter;
❒Lambda sensor;
❒fuel evaporation system.
In addition, do not let the engine run, even for a test, with one or more spark plugs disconnected.
The devices for curtailing diesel fuel engine emissions are the following:
❒oxidising catalytic converter;
❒exhaust gas recirculation system (E.G.R.);
❒diesel particulate filter (DPF).
DIESEL PARTICULATE FILTER (DPF)
(for 1.3 Multijet 90 HP version)
The Diesel Particulate Filter is a mechanical filter, integral with the exhaust system, that physically traps
particulates present in the exhaust gases of Diesel engines. The diesel particular filter has been adopted to
eliminate almost totally particulates in compliance with current / future law regulations. During normal use
of the vehicle, the engine control unit records a set of data (e.g.: travel time, type of route, temperatures, etc.)
and it will then calculate how much particulates has been trapped by the filter. Since this filter physically
traps particulates, it shall be cleaned (reclaimed) at regular intervals by burning carbon particles.
Reclaiming procedure is controlled automatically by the engine control unit according to the filter conditions
and the conditions of use of the vehicle. During reclaiming the following phenomena could take place: idling
slight increase, fan activation, slight smoke increase, high exhaust temperatures. These situations shall not be
considered as faults and they do not affect vehicle performance and environment. If the dedicated message
is displayed, refer to paragraph “Warning lights and messages”.
