Burning of soot particles


With this function it is possible to burn soot particles in the particulate filter via the engine control unit (ECM)

Important! Burning of soot particles (regeneration) shall be run outdoors. If that is not possible, the particulate filter shall be replaced.

The burn phase may take up to 1 hour and consists of four phases:

1. Start-up phase, a start command has come from the user.

2. Warm-up phase, all start conditions are fulfilled and engine speed is increased to approx. 2000 rpm.

3. Burn phase, temperature in the particulate filter increases to 600 °C. The burn phase lasts for approx. half an hour.

4. Cooling phase, to avoid overheating the engine speed will be at approx. 1200 rpm until the temperature in the particulate filter has dropped below 300 °C and the temperature in the catalytic converter has dropped below 230 °C.

Note:

Test conditions:

Procedure:

  1. Check that the start conditions (test conditions) are fulfilled.

  2. Select function: "Burning of soot particles".

  3. A dialogue box shows: "Soot amount in particulate filter" and "Pressure particulate filter".

  4. If the soot amount is 100 or the pressure in the particulate filter is above 100 hPa, press "Cancel" and replace particulate filter. Otherwise press "OK" to continue.

  5. A dialogue box shows: "Start burning", burning of soot particles may take up to 1 hour. Press "OK" to start the function or "Cancel" to abort. Warning! Temperature of the exhausts may increase to approx. 600 °C. Make sure that exhaust extraction and associated equipment tolerate the high temperature.

  6. A dialogue box shows: Regeneration process activated, engine rpm increasing. If burning has to be aborted, select "Cancel".

  7. The regeneration process may take up to 1 hour, when the engine rpm returns to normal idle the function is done.

  8. Press "OK". A dialogue box shows "Soot amount in particulate filter and pressure in particulate filter after regeneration". Press "OK" to finish.

    If the burn fails or is cancelled, check test conditions, the particle filter may need to be replaced.
