Parked regeneration cannot be initiated during which operation?

Parked regeneration cannot be initiated during which operation?

• A. Driving operations
• B. Idling
• C. Pumping operations
• D. Shutdown

Answer: (C)

Parked regeneration is a controlled cleaning of the diesel particulate filter that needs the engine to run at a stable, high exhaust temperature while the vehicle is stationary. When the apparatus is pumping, the engine is under a heavy load to drive the water pump, making it hard to reach and hold the exact conditions the regeneration requires. This load can prevent the exhaust from reaching and sustaining the temperature needed, and it can also interfere with pump operation. So, you don’t start a parked regeneration during pumping operations. It should be done when the vehicle isn’t actively pumping and the engine can stay in a suitable, low-load state.
