MBE 900 ENGINE 2007 OPERATOR'S GUIDE Parked Regeneration will begin blinking and a parked regeneration should be initiated as soon as possible. If the flashing DPF is still ignored, the AWL (Check Engine), listed in Table 3, will illuminate. This will be accompanied by a 25% engine torque reduction. Regeneration of the Aftertreatment Device (ATD) is fundamental for the oxidation of soot. This process happens during the normal operation cycle of the vehicle; it can occur both passively and actively. Regardless of this, the operator will see no difference in vehicle performance or vehicle control.
If the ATD is not capable of completing regeneration due to duty cycle constraints or other restrictions, a parked regeneration may need to occur. 3. If parked regeneration is still not initiated, a standard 60 second engine shutdown sequence will occur. All of the following dashboard lamps will be present, blinking DPF Regeneration Lamp, solid AWL (Check Engine), and solid Red Stop Lamp (RSL)/Stop Engine, listed in Table 3. Once this engine shutdown sequence is completed, a parked regeneration must occur to continue vehicle operation. The driver will be notified of the need for a parked regeneration by illumination of the Diesel Particulate Filter (DPF) lamp as listed in Table 3.
If the driver continues to operate the vehicle without a regeneration, additional measures will be taken to protect the engine and ATD device from damage, up to and including engine shutdown. If the driver continues to operate the vehicle without a regeneration, additional measures will be taken to protect the engine and ATD device from damage, up to and including engine shutdown. Described below is the procedure for performing a parked regeneration. The sequence of indicator lamp(s) is as follows: 1. The DPF Regeneration Lamp will be illuminated prior to any engine protection measures being taken. Once this lamp is lit, the parked regeneration process should be initiated. NOTE:
If the DDEC VI electronics have not requested the initiation of a parked regeneration (the DPF Regeneration Lamp is not illuminated), the regen request switch is disabled. 2. If no DPF regeneration occurs after the initial DPF Regeneration Lamp illumination, the lamp All information subject to change without notice.
