EVIC Message today Diesel exhaust filter 100% Full Regeneration in progress

[Ben S]

Truck in my signature gave me the information message on my display today . "Diesel exhaust filter 100% full. Regeneration in progress." Never have received this message before. Truck has 30,000 miles on it and runs great. All updates have been performed.

Received the message on my way to work today after about 12 miles of driving at 45 mph. Drove the truck last night at highway speeds between 55 and 70 mph for two hours before I parked it and let it sit over night. DEF is full. Yesterday the truck made an 8 hour round trip mostly at highway speeds between 55 and 70 mph.

I could not screw around driving around while the thing finished its regen as I had to go to work. When I parked the truck I could here it and smell it doing its thing with the soot trap just like all the other times before. But I have not ever received this message before.

So why am I getting this message? Timing seems odd to me.

 

[Ben S]

Well I took the truck out on the interstate tonight and it gradually cleaned the particulate trap giving messages as it went down to 80% 70% then complete.

Just had not seen this message before . Still think it's odd considering all the interstate driving yesterday.

I agree, does seem an odd time to 'fill' the filter. I'm curious about what you learn, your results, and what others here might share. I have a similar emissions truck, a 2014 2500, though with a G56 manual.

Me too it can be helpful to know.

I had a similar surprising response earlier this month. Wish it would check the filter more often when driving at highway speeds and regen when on the highway even if less than 100% full. But even if it checks the DPF regularly, it doesn't want to active regen until its at 100% full. I think it passive regens on the highway which seems to just keep it from adding soot to the filter, but doesn't clear all the old soot out. In less than 2 weeks, I'll be on a 4 state trip pulling a small rig. That should clear my DPF out for a few months. A month ago it went through active regen and counted down to 0%. I only put 9,000 moles/year on the truck. It probably wants more hwy miles.

You are only notified of an active regen when it is full, otherwise regen goes on behind the scenes.

The EGTs required for a passive regen are pretty high and it doesn't always occur just driving on the interstate.

? DEF or DPF

? DEF or DPF

I understood DPF. It only notifies when DPF is 100%

I remember when I bought my former 04.5. Lot's of people said to drive the **** out of it now in then. Do you guys think rompin' on these newer trucks once in a while that it would help the DPF cycle more often? Or would it simply cause more soot build up?

It's my understanding, and keep in mind I only have 4,600 miles on my '15, that since the pee tank acts as a catalyst and prevents the build up to begin with, the driving the **** out of it isn't necessary. Active regen typically (from what I've read), lasts a few minutes when it's necessary, and you don't even know it's happening. Because the soot never escalates to the point where stuff gets clogged up, due to the DEF, in theory "we" should not have the problems of the last iteration of our trucks had. In theory.

I understand it diffetently. DEF is for NOx. And had nothing to do with Regen or soot.

This is true. With that said, DEF indirectly helps reduce soot.

Low combustion temps produce less NOx, but produces more PM's (soot). High combustion temps produce less PM's but more NOx, it is also more efficient. Since NOx is now dealt with in the exhaust with DEF and a catalyst, combustion temps can be higher for less PM creation making life easier for the DPF.

Oh, yeah I agree. The DPF and DEF are both after treatments which allow Ram to meet emissions regulations while changing the tuning of the engine for higher operating temps and less EGR. Indirect relationship. No causal relationship

 

[Newsa]

Running the engine hard under load my help burn off soot in the exhaust/emissions system. But I doubt it will affect soot content of the oil.

Ever see a deleted diesel under load? Soot increases with load. But that might be exaggerated in some trucks with the larger injectors/mods.

 

[Ben S]

Ok. Follow up to this thread. This message started displaying after the last reflash and updates on the truck. It has now happened 3 or 4 times and never affects the operation of the truck. After several minutes of running with the exhaust brake turned on the message will count down emptying the filter until 70% full then say complete empyting and remove the message. I assume this must have been part of the reflash to notify the driver of it the truck cleaning the soot trap.

The Regen Process for MY13/14
 Soot load is the primary regen trigger
– wiTECH parameter: AFT Combined Soot Load Estimate
– Soot load measured in grams/liter (g/L)
• Grams/liter = amount (grams) of soot per liter volume of the DPF
– Trigger for Start of Regen: 4.00 g/L
– Trigger for End of Regen: 2.00 g/L
 Soot level timer is not the same as MY12 and Older
– Now used as a 24 hour regen timer based on operating time
– If a customer’s duty cycle is such that the soot load never reaches the regen trigger, the
truck will go into regen when the operating time from the last regen reaches 24 hours
– Basically, the truck will do at least one regen every 24 hours of operating time

Well just as strangely as the EVIC began displaying the message regarding regeneration it has just as mysteriously stopped displaying the message about regeneration. There have been no flashes or updates in between. Truck now has 35K miles on the clock.

Mine used to show regens on the EVIC. Hasn't for about a year now.
