2008 f450 1000 gallon avgas truck DPF questions

[DVOfuel]

hi everybody, this is my first post on the site, my question is some what unique since most of you guys are running trucks quite different than the intended purpose of mine. I have a 2008 f450 chassis with a 1000 gallon 100ll avgas tank that spends 90% of its time sitting there idling on the tarmac running a PTO pump to fuel up aircraft. So far the trucks been great and we've been very happy with it, today i was noticing the section on DPF regeneration in the manual and i thought to my self hummmmmmmmm this could be a problem, its states "drive to clean the exhaust filter at 30mph for at least 20 minutes" this however is not possible at my airport (not only is the speed limit 15 but i can just imagine the looks of incoming pilots when they see me hot lapping the runways) and this truck is not street legal since it will never leave the airport, my first question is can I achieve the same effect by idling at a constant rpm with the vehicle in neutral? this i figured is a long shot since it sounds like this whole process is computer controlled, i am well aware that since it isn't street legal i could most likely remove some of these components and smog equipment with a DPF delete kit, but i live in CA and the greenies are becoming increasingly unrealistic with idling diesel policy, and we are inspected by quite a few different agencys. I was curious if any of you have heard of this problem with vehicles such as this truck, i'm still kind of perplexed that the manufacturer would have chosen an engine chassis combo for this application considering this process. thanks for your input

PM Me. I likely have a solution for you.

It may or may not be legal in your jurisdiction.

I will likely not be able to reply until sometime later on Sunday, in advance warning.

Hillbilly will get ya going in the right track...

IMO Ford (or any of the other manufacturers for that matter) absolutely did NOT consider idle applications when they designed their reburn exhaust systems. I live in oil patch country where trucks sit on leases and idle all day. If I had a buck for every 6.4 or semis with reburn systems on them that I have towed I would be rich. For the exhaust system to work properly, you MUST take it for the prescribed drive when the truck wants it. It's especially bad during the winter when guys have no choice but to leave trucks running 24/7.

This has become a SERIOUS problem in my area and about the only fix that I have seen is a DPF delete...


Hillbilly, can you tell me about your solution? Either PM me or post it? Thanks.

Oh and ten points for the Robert Service quote

I have nothing to add to this, but I just found this completely hilarious

Since it's not street legal, I'm wondering what CA would say about a DPF delete. Do they require emission components on construction equipment?

For equipment, tractors, large generators etc. over 50hp you pay a fee to the state to allow you to use a non emission controlled vehicle. I don't know if a truck without a DPF would be inspected by the state since it's not going to be licensed. Also if the truck is listed as off-road equipment, just as you would a farm truck, it shouldn't require smog or emissions equipment since it won't need to be licensed to drive on public roads.

thanks all for taking the time to reply, the more research i've done the less excited i am to have this system on my truck, i just talked to a tech today who told me that exhaust gas temps have been known to reach in excess of 3000 degrees Fahrenheit and he heard of a fuel truck that even cracked concrete in regen mode (my truck has a exhaust system that dumps under the front bumper, so its not to close to the tank) but considering those temps on a truck with a 1000 gallons of aviation grade fuel this seems like a issue that may not have been throughly considered by the manufacturer, but hind sight is always 20-20, so correct me if i'm wrong but this process is achieved by injected fuel into the cat?
