DEF - Diesel Exhaust Fluid Video

Is the animation accurate for Ford diesel trucks? I'm only familiar with GM's system and the SCR/DPF is a single unit with the SCR first. DEF is injected upstream of the SCR/DPF not after the DPF as illustrated in that animation

GM and Ford are similar with SCR first. Cummins has the DPF first.

It will be interesting hearing the price to replace/or clean the added exhaust items when its time. Not sure how many miles they have in their life span.

That's one of the reasons why I started this topic. I'm hoping to hear about how other owners handle that as well, especially when the vehicle is out of warranty.

I'm also interested in discussing and learning how these systems work. There does seem to be a fair amount of misinformation out there about DPF's, DEF, and SCR.

Thanks for the link. I've always knew of it, but it's nice to see how it actually works.

Goofy things about the video:


They show the exhaust exiting the left side of a truck. Left side exhaust exit hasn't been done on new diesel trucks.

At 4:05 they say "refuel the DEF tank" (wait, DEF isn't FUEL)

Another good video regarding Ford trucks

Thanks, I drive a gasser but I learned something about new diesels.
