Description
(1) particle filter
"a" exhaust gas inlet (after the catalytic converter)
"b" exhaust gas outlet
Make: EBERSPÄCHER
The particle filter is a porous structure of silicon carbide including channels arranged so as to force the exhaust gases to pass through the walls
Components retained in the particle filter
- Carbon particles
- Additive
- Deposits from the engine oil and engine wear
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" inlet channels
"d" outlet 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 550°C (natural regeneration or with the assistance of post injection)
Use of the additive has the effect of lowering the combustion temperature of the particles to 450°C (temperature of the exhaust gas at the outlet from the catalytic converter during the regeneration phase)
The additive is an inorganic substance which does not burn but is retained in the particle emission filter in the form of a solid deposit
NoteThe accumulation of particles whilst the engine is operating leads to the progressive clogging up of the particle filter
