Idling....

[SDST08]

Has anyone ever noticed that the new 6.4 will produce a different odour when it is idling. My truck only has about 3500km on it and I just started noticing it on the weekend. You can smell it while in the vehicle or as far as 40 feet from it outside. Just wondering if anyone has any comments on this?

Our's does the same thing. Not sure if it's due to the ULSD of just a trait of the 6.4. No doubt it burns cleaner.

I figured it might be the ULSD too, as long as it isnt a problem!! Sure does stink though!!

I miss the old diesel smell. Good thing we have some old 6 cyl Deeres to get my fix.

Ok I am still pretty new to diesels and especially this new regen process. How long does it last? Because I noticed it on 3 short trips on 2 seperate days.

You will notice the truck is in regen if you put it in park and the idle rpms go just a tad over 1000 rpm. I just let it finish. It doesn't take that long (at least on mine). The regen is working and is cooking the soot off the ceramic DPF. It smells like a new gas grill that you've heated up for the first time. I can hear the metal popping and expanding while it's going through the regen. It's pretty hot under there too.

it also can do a regen anytime the dpf sensor feels it needs it so there is no set schedule or time , if it does it going down the road , it will feel slightly underpowered
