Exhaust post-treatment
Generating sets with engines complying with STAGE V exhaust gas regulations require special devices to
reduce the emissions of pollutants in exhaust gases.
Depending on the engine output, the after-treatment system includes the following devices:
•
Doc (Diesel Oxidation Catalyst): catalyst to purify exhaust gases
•
DPF (Diesel Particulate Filter): particulate filter that captures soot in exhaust gases
•
SCR (Selective Catalytic Reduction): device that purifies nitrogen oxides (NOx) in engine exhaust gases.
On engines with power from 19 kW to 56 kW, there are DOC and DPF devices.
On engines with a power greater than 56 kW, there are Doc, DPF and SCR devices.
6.6.1 Particle filter (DPF) regeneration
Regeneration is the term used to describe DPF cleaning.
During this process, the particulate is subjected to further oxidation within the DPF.
The exhaust gas temperature inside the DPF exceeds 600°C, burning the particle matter.
6.6.2 DPF regeneration strategies
DANGER
•
During the DPF regeneration procedure, make sure that there are no people, animals or flam-
mable material nearby and that the place is well ventilated.
•
Remove all flammable material that may be present around the machine such as dry leaves or
pieces of paper.
•
During DPF regeneration, avoid approaching the outlet of the exhaust pipe and walking around
the device to avoid burns.
Also, keep flammable materials away from the exhaust pipe to prevent fires.
•
Carefully check the machine and the surrounding area to verify the absence of incandescent
residues during and after DPF regeneration.
Passive regeneration
•
It is a normal chemical reaction not governed by the control unit.
•
It occurs during engine running under normal conditions.
•
Passive regeneration does not affect the operation of the machine and does not require any intervention
by the operator.
•
No signal is provided on the control panel.
