Diesel particulate filter regeneration (Cummins engine only)
Under most operating conditions, DPF regeneration will be transparent
to the operator. A small increase in engine/turbo sound-level is normal
during filter regeneration. If, however, your engine is operated for
extended periods of time under one of the following conditions, operator
assistance may be required to facilitate the filter regeneration process:
•
Vehicle is operated in stop-and-go traffic and/or maintains low speeds
as in a city/delivery driving
•
Engine is started and shut-off frequently
•
Vehicle payload is relatively light
•
Vehicle is regularly operated in cold ambient temperatures (i.e. below
0°F [-18°C])
