What is DPF Regen inhibit?

Regen Inhibit (switch on right) allows you to cancel or stop an. Exhaust Regeneration. (

How can I reduce my DPF regeneration?

A premium diesel fuel like CENEX® ROADMASTER XL® can reduce the need for DPF regeneration. With an additive package engineered to meet the demands of today’s high-performance diesel engines, Roadmaster XL provides a cleaner, more complete burn.

What happens if you interrupt DPF regeneration?

Regeneration, or regen, of the DPF filter, is the process that burns the soot accumulation that is inside the DPF filter. If you can no longer start a regen then you will eventually get stuck in a derate which will then lead to an engine shut down.

What triggers a DPF Regen?

DPF regen happens when the trapped particulates heat up enough to combust and turn to ash. The built-up soot is then removed as gaseous carbon dioxide.

Can you drive during a regen?

The only thing required of the driver during this process is maintaining driving speed during the process. If driving speed is interrupted as active regen occurs, you will likely have to restart the process again the next time you are up to speed.

How do I stop diesel regeneration?

Regen problems can be easily fixed… By far the best approach is to reduce the temperature at which the soot particles burn, by adding FTC Decarbonizer to the fuel at each fill. This reduces the soot burn temperature to 350-400C…a temperature readily reached by engines under even light loads.

What causes excessive Regen?

The most common reason your truck regenerates is a clogged DPF filter which becomes clogged because of too much soot. When the filter becomes clogged, the ECU will activate regeneration to clean it up. You can also initiate regeneration with an auto tool, or clean it yourself using special additives or cleaners.

What causes frequent Regen?

Regen problems generally arise where city driving, excessive idling or light duty cycles are encountered. Or, if other engine components such as EGR valves, turbochargers, injectors are fouled or not working properly. DPF regeneration cycles then become more frequent, and more prolonged!

What is one common cause of a DPF system continuously regenerating?

Your DPF regenerates because of excessive exhaust soot overwhelming the DPF. Exhaust soot is the product of incomplete combustion, the soot is actually partially burned fuel. Soot creates back pressure and the regeneration is triggered and your headaches begin.

Does a regen stop on its own?

A parked regen is controlled by your truck’s computer system and only requires the correct conditions to be met. The process should last between 45 minutes to an hour and no longer.

What is a Regen inhibit switch on a fire apparatus?

The regen inhibit switch is required by the National Fire Protection Association (NFPA) for all custom chassis fire apparatus to prevent the engine controls from automatically initiating a regeneration event when the apparatus may be operating in a hazardous environment where elevated exhaust temperatures could create a safety concern.

How does a DPF Regen work?

“The DPF Regen contains the heat of the exhaust, adding up to temperatures exceeding 1000 degrees Fahrenheit, so that the filter is depleted of its buildup and returns to proper functioning capabilities.” What Are DPF Regeneration Cycles?

What is passive regeneration of a DPF?

If the temperature of the exhaust is high enough, some of the PM present in the DPF will burn off on its own. This is passive regeneration. Under optimum conditions for passive regeneration, the PM loading of the DPF will be reduced.

What is the difference between passive and active regeneration?

Any apparatus with a DPF will require regeneration. There are two main classifications for regeneration: passive and active. The difference between passive and active regeneration involves whether or not the engine controls actively participate in starting or maintaining the regeneration event.
