DPF Fueling Location

Dad and I are at it again!

He has one theory, I have another regarding the DPF Fueling.

This is are question:

When the regen mode is active, at what point in the exhaust system is the fuel injected into the system? Is the extra fuel injected into the cylinder on the exhaust stroke, or is it injected right into the Self Bake Oven??

This all started because he was under the truck and saw fuel lines going into the DPF. To my memory, there is no fuel lines down there (what they are, I don't know. Have not been under there yet). I was under the impression that it was on the exhaust stroke, hence the reason the oil gets contaminated with fuel quicker.

So, who is right?? Is dad of his rocking chair, or do I need to be more respectful to my elders??

Thanks!

Robert
