When the filter medium has trapped a specific amount of soot, it is regenerated while the machine
is under LOAD. The control unit initiates and monitors the regeneration process. Diesel fuel is in‐
jected into the exhaust stream. This causes a special catalyst to heat the exhaust gas to over
550 °C and the soot is burnt off the filter medium in CO₂.
The machine is shut down if the back pressure in the exhaust exceeds a specific value.
