Can I regen while driving?

An automatic regen does not require any action by the driver, other than making sure the truck stays ON. It is safe to continue driving as normal. A regeneration cycle typically takes between 10 and 30 minutes to complete.

Can you drive while truck is in regen?

The vehicle needs to run at operating temperature during the regeneration, so highway driving is best. Just drive as you normally would. During active regeneration, the exhaust outlet temperature is extremely high. So watch your location if regeneration is about to begin.

How long does a regen take while driving?

A forced regen occurs when soot builds up inside the diesel particulate filter (DPF) to the point that the vehicle is no longer operable. When this happens, a driver has to pull over and initiate a self-cleaning process that can take up to 40 minutes — valuable time that could have been spent on the road.

What happens if you interrupt a regen?

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.

How long should a parked regen take?

How long does a parked DPF regen take? It takes approximately 20-60+ minutes. It will continue to regen until the soot level has reached 'low' or '0%. ' Some trucks will let you monitor your soot level gauge on the dashboard.

How do you regenerate DPF while driving?

To make sure that the regeneration takes place, most manufacturers suggest that every few hundred miles, the car is driven for a period of more than 15 minutes at a consistent speed of more than 40mph. Doing this should kick-start regeneration and clear the filter.

What happens if regen takes too long?

If your forced DPF regen lasts closer to an hour or continues beyond that, it likely suggests that your exhaust temperatures are not building up high enough to successfully burn off the soot collected in the DPF and that the truck is still trying to bring down those soot levels.

Can a diesel regen while driving?

Most engine management systems will actively regenerate the DPF when the car is driven at speeds above 40mph for around 10 to 15 minutes. The soot particles trapped in the filter will soon burn away and the warning light should switch off.

Does regen use more fuel?

Active DPF regenerations need to burn extra fuel to achieve the high exhaust temperature for soot oxidation, which results in the increased fuel consumption rates.

Can a forced regen damage engine?

Force regeneration of the particulate filter

The ash from the engine oil accumulates on the inner walls of the ceramic and in the pores. This increases the pressures in the DPF and if clogged, can even damage the engine.

How do I know if Regen is working?

An active regen cycle is a normal process that takes place as the truck is going down the road. A computer sensor monitors the DPF and a dashboard indicator light notifies the driver that the regen is taking place, or the DPF is now cleaning. “You'll notice a reduction in power during a regen,” notes Nace.

Can you operate a tractor during regen?

Other ReGen tips

If you should happen to get a ReGen notification when you are minutes away from finishing your tractor chores for the day, we recommend you leave your tractor running while the ReGen process completes.

What is the longest a regen can take?

On average, it takes between thirty and sixty minutes to complete a forced regeneration. The substantial heat required for the regen renders the engine and aftertreatment system untouchable until it has time to cool down.

What happens if I turn my car off during DPF regeneration?

The DPF regeneration process creates very high exhaust gas temperatures and the exhaust will radiate a considerable amount of heat during and after DPF regeneration, and after you have switched the engine off. This is a potential fire hazard.

Do diesels smoke during regen?

In a Diesel engine with a Diesel particulate filter (DPF) system, high-sulfur fuel causes white smoke containing odorous and harmful pollutants during DPF regeneration.

Why is my truck asking for a regen so often?

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!

How can I regen faster?

Why do I have to regen every day?

A forced regen occurs when soot builds up inside the diesel particulate filter (DPF) to the point that the vehicle is no longer operable. When this happens, a driver has to pull over and initiate a self-cleaning process that can take up to 40 minutes — valuable time that could have been spent on the road.

Should you change oil after regen?

Check the oil levels because some levels can rise due to regeneration as fuel gets into the oil. Oil and oil filter must be changed before replacing the DPF.

How can I save diesel while driving a truck?

How long should you let a diesel idle after driving?

Always follow the manufacturer's recommendations around idling. proper circulation and cooling of the engine oil, coolant and turbochargers, not to exceed five minutes. If the engine must be left running for any reason the operator must remain in the vehicle.

When should I manually regen?

Manual -- This type of regeneration occurs only when the vehicle is stationary, and it requires action on the part of the vehicle operator. The check engine light will illuminate on the vehicle dashboard, usually after an extended period of idling (when hydrocarbons build up and can cause overheating of the DPF).

How long does regen in progress last?

You must keep the RPMs up during the regen, which will last about 15 minutes. If you're doing something that requires high RPMS, like tilling or mowing, you may not even notice the process is happening, because there is nothing for you to do. During this time, the indicator light stops blinking and is on and steady.

How much does a forced regen cost?

A forced regeneration can be performed by any service shop with the appropriate diagnostic software. The cost for a forced regeneration varies. Generally, it is between $300-$700 depending on the technician's required diagnostic time and the length of time your DPF regeneration lasts.
