Parked regeneration duration is approximately?

• A. 20-40
• B. 5-10
• C. 60-80
• D. 15-25

Answer: (A)

Parked regeneration is the process of burning off soot in the diesel particulate filter while the vehicle is stationary. It relies on sustaining higher exhaust temperatures for a period of time to oxidize the accumulated soot and bring the filter back to a clean state. In practice, this procedure typically runs for about twenty to forty minutes. The duration is longer than regeneration while the vehicle is moving because heat needs to be built up and maintained to complete the burn-off, which takes time depending on how much soot has built up. Shorter timeframes, like a few minutes, wouldn’t be enough to complete a full burn, and a very long period would indicate an unusual or heavy-duty condition. The rule-of-thumb range used here captures the normal, expected window for a parked regen under typical conditions.
