Regeneration of particle filter


This function cleans the particle filter from soot particles by burning them off using an increase in the exhaust temperature. In certain driving conditions, the particle filter can not be cleaned automatically, e.g., in continuous city driving. Then this function is used to force a regeneration.

Note:

Test conditions:

Procedure:

  1. Start the function.

  2. Current soot quantity in the particle filter and limit value for regeneration are shown. Due to the risk of fire, do not perform regeneration if the soot quantity is over the limit value.

  3. Criteria for successful start of regeneration are shown with current reference values. When all criteria are fulfilled, press "OK".

  4. The following instructions are shown in order and shall be followed to start regeneration:

    • Brake = Press down brake pedal.

    • Clutch = Press down clutch pedal.

    • Let up = Let up pedals.

    • Full load = Press down gas pedal all the way.

    • Let up = Let up pedal.

  5. Regeneration starts, this is indicated by the engine rpm increasing to 1,500 rpm and the heating coil in the instrument starts to flash.

    • If regeneration does not start, exit the function, restart the car, and check test conditions.

  6. Regeneration's status and exhaust temperature are shown during the whole regeneration sequence.

  7. Regeneration in progress can be cancelled by:

    • Affecting brake pedal or clutch pedal.

    • Turning off engine.

    • Any test condition not being met.

  8. The engine rpm returns automatically to normal idle and the heating coil in the instrument turns off when regeneration is done.

  9. The function is done.
