What is a regen inhibit switch?

Some vehicles may be equipped with an ‘Inhibit Switch. ‘ The purpose of this switch is to prevent or disable Aftertreatment Diesel Particulate Filter regeneration. Again, reference the OEM’s Owners Manual for complete operation and use of this switch.

What is the Regen inhibited?

Inhibit Regen defaults to OFF when the machine is turned on. Parked Regen – Used to start a Parked regen cycle when requested or desired by the operator. May also be used to cancel a Parked regen cycle when the cycle is running.

It can be easy to interrupt the process if you only ever make quick trips around town in your car. If you switch your car off while it’s halfway through active regeneration, it may cause problems, and the filter may not have been properly cleaned.

What is DPF regeneration inhibit?

Regeneration is inhibited by driver actuation of another switch for a maximum amount of time that may be shorter, or even prevented if DPF loading is too high.

Can you stop a parked regeneration?

How do you release the DPF inhibit switch on a Volvo truck?

Press UP on top switch and hold for a moment (only for parked regen). 2. Release the switch. STOP Regeneration (ONLY if unsafe to perform a regen).

What is the purpose of active regeneration?

Active regeneration is triggered when the exhaust back-pressure across the DPF is sensed to have reached a first critical point, whereupon the ECU initiates a fuel injection routine designed to increase the exhaust temperature in the DPF to over 600 °C in order to oxidize the particulate deposits.

Can you regen while driving?

When everything is working as it should, regeneration occurs automatically while the vehicle is in motion, unnoticeable to the driver. Using the heat of the exhaust itself, soot is burned off the DPF often as quickly as it accumulates. This is known as passive regeneration.
