2015 6.7 DPF Regen Design

[Sarge03]

Hey guys, can anyone tell me how the 2015 conduct the Regen cycle? Does it dump fuel on the exhaust stroke or does it have a bypass system using an injector by the DPF like the Duramax?

Well I think I found the answer but now I have more questions.... If the regen cycle is completed by fuel being dumped into the cylinders on the exhaust stroke, couldn't there be a concern for fuel contamination in your crank?

Yes, I am not sure what if any changed for 15 but in the 6.7 class I went to they said it used all 4 cylinders opposite of the egr to regen. Where the 6.4 only used 2 cylinders it uses 4 and I would assume smaller amounts of fuel per cylinder would help keep contamination at minimum.

Gotcha. Thanks for the input. Completly new to diesel and trying to learn all I can about how my new engine works.

I've done oil samples of mine deleted and emissions intact and fuel in oil has always been .5%.
