Which describes when automatic regeneration occurs?

• A. Automatic regeneration
• B. Manual regeneration
• C. Overheat protection
• D. Idle mode

Answer: (A)

Automatic regeneration is when the system starts the cleaning cycle by itself, without the driver needing to do anything. The engine control system monitors soot buildup and exhaust temperature and automatically initiates the regeneration when conditions are right, using heat and sometimes extra fuel to burn off the accumulated soot in the particulate filter. This happens during normal operation or under drive conditions, not under driver control. Manual regeneration requires the operator to start the cycle, overheat protection stops or limits regeneration if temperatures get unsafe, and idle mode is simply engine idling and not the trigger for regeneration.
