Help understanding the regen system D6T

HI Guys,

I have a 2011 D6T ZJB00289
The manual isn't clear on how the regen system is meant to function

For instance, is it ok to shut the machine down during an active regen. The machine does an auto regen quite often throughout the day (light finish dozing) and today at the end of the day it was still on at quittin time.

How do you do a key off regen. Manual says its possible, but isn't clear how.

You can turn the key to the off position whenever you want no matter what it’s doing. They have 4 key positions now. When you shut it off during a regen it will stop the regen but run for a few minutes to cool off. Take your key out and let it finish. In emergency turn the key back further to the 4th position and it will shut down immediately. If you do this the computer logs a code and is not good for the machine. So you may notice it runs still when you turn it off and this is normal and let it cool off. Then also there is a light by the night switch key (if it’s tier 4 final). Do not turn off the night switch till it goes out (1-2 min after the engine shuts off). This is pumping the DEF all back to the tank. Again if you turn off the night switch when the light is on it will log a code and you risk freezing damage to the DEF lines in the winter

It may be possible but is just not advisable.

I forget all the nuances with the system but basically back pressure turns the system on and it goes through the prescribed process of burning all the fuel soot and turns it to ash. There was no DEF on that year of machine so the regen process happened pretty frequently in that time frame. When the system first came out you had to stop the machine while it went through the process. Then the manufacturer turned around and said you could run the machine if it had a heavy continuous load while it was in regen. If it went into regen while sitting and idling you had to wait. I've been told that changed again just before tier 4 final came into affect. The DPF has to be removed and cleaned of all the ash after a certain period of time. I was told it was base on fuel burn instead of actual time but basically what I've seen is the more fuel you burn the faster the computer will tell you it is time for a clean out. That apparently happens somewhere around 5,000 hours of operation.

There are a lot of people who will tell you how it works but just like me here aren't real sure of the nuances. Were it my machine I would likely be looking for something in writing to use to train the operators on how it is absolutely supposed to be done. It is costly and time consuming to repair that mess of add on hardware.

Simply just get rid of it all and not have no more head aches and down time... ‍♂️

I keep forgetting, you guys have that option. You suck.

We can do DPF delete with official CAT decertification files for NRC (non regulated countries).
That is 100% CAT file, not a custom made solution - so You can feel 100% confident in it.

Haha. Another spam. He just doesn’t understand how this forum works.
