The catalytic converter is a device that simultaneously reduces the three main pollution components in the exhaust: Unburnt hydrocarbons (HC), carbonmonoxide (CO) and nitrogen oxides (NOx). Inside the catalytic converter two chemical reactions take place: •Oxidizing of the CO and HC, converted into carbon dioxide (CO2) and water (H2O);
• Reduction of the NOx converted into nitrogen (N2).
These reactions are possible in a very short time due to the presence inside the structure (metal block) of the
catalyst, of a layer of active substances (platinum and rhodium) that considerably speed up the conversion of the harmful substances.

Moreover the conversion processes take place with temperatures over 300 to 350°C: Therefore it is essential that
the catalytic converter reaches this temperature as soon as possible so as to operate correctly.

The exhaust pipe coming out from the catalytic converter features a thermocouple to read the temperature. This
thermocouple generates a signal in proportion to the exhaust gas temperature and sends it to a special electronic
control unit that switches on the “CATALYST RIGHT” or “CATALYST LEFT” warning light to which it is connected.
If there is an abnormal temperature increase in one of the catalytic converters the control unit intervenes as follows:•For temperatures ranging between 945 and 960 °C the “CATALYST” warning light switches on intermittently:

Secondary air supply system strategy When the car is turned, if the following conditions occur: •Water temperature between -11°C and +40°C;
• Air temperature <40°C;
• Catalytic converter temperature <250°C;
the pump is controlled: its maximum time is 65 sec.
The pump will stop if any one of these conditions occurs.
To deactivate the system (and disable the pump), one of the following conditions must occur: • Catalytic converter temperature >680°C;
• Air temperature >40°C;
• H2o temperature >40°C;
• Any condition related to the temperature but with a PA1024 >99%.
This system is used when the car started with a cold engine, to increase combustion and allow the catalytic converter
to reach its operating range quickly, reducing emissions.
