Description
(1) particle filter
"a" exhaust gas inlet (after the catalytic converter)
"b" exhaust gas outlet
The particle filter is a porous structure of silicon carbide with channels closed alternately at their ends
Components retained in the particle filter
- Carbon particles
- Deposits from the engine oil and engine wear
NoteThe particle filter works without additive
Role
The particle filter traps carbon particles as the exhaust gases pass through
Function
"a" exhaust gas inlet (after the catalytic converter)
"b" exhaust gas outlet
"c" outlet channels
"d" inlet channels
The particle emission filter is made up of entry channels closed at their end, which forces the exhaust gas to go through the walls of the channels. These work as a filter and retain the particles
Essentially consisting of carbon and hydrocarbons, these particles on the particle filter burn in the presence of oxygen at a temperature of 650°C (natural regeneration or with the assistance of post injection)
The service life of the particle filter varies according to the driving conditions
The service life of the particle filter is on average 250 000 km
NoteThe accumulation of particles whilst the engine is operating leads to the progressive clogging up of the particle filter

Programming/initialisation
Programming is necessary if the component is replaced
