DIESEL PARTICULATE FILTER (DPF) - do I have one?? LOL
Brad was looking at Penrite oil on the net and a few types said "not suitable for vehicles fitted with DPF" He'd never heard of it & as I'm the message courier I jump on here to ask the experts .

DPF- diesel particulate filter. Just more envirnomental rubbish that causes drama. In most cases it will have a regeneration cycle so when the soot load in the filter becomes high it uses temperature to then burn the carbon and "clean" the filter.
As far as I know patrols don't have them, in aus anyway. I could be wrong do if anyone has info on if they do that would be great.

I know iveco trucks have them and from what I've herd you don't want to be parked on grass when it burns off.

It might seem like environmental rubbish but diesel particulate matter is a carcinogen, particularly harmful and has been recognised as such. I have no issue with something that is designed to reduce the damage that diesel particulate matter might do to the lungs of my kids.

Diesel particulate filter is just like a catalytic converter for petrols, its a catalyst to change harmful gases into neutral gases but mostly change them into water.

You are correct but that describes a Diesel Oxidation Catalyst (DOC) Filter.
Most versions of DPF's don't handle gases or water conversion as such. They are soot burners.
They trap the soot in the filter and burn it off at high temps of either:
600 degrees or higher (regeneration) which they achieve thru hi speed operation or raising EGT's by late fuel injection or injecting extra fuel
Or...
400 degrees or so by the use of a catalyst such as "adblue" which allows the lean off of the fuel to reduce soot and then the Adblue handles the spike in NOX because of the lean burn.
Adblue (or it's counterparts) are in those placcy drums you sometimes see the truckies using when they fuel up.
Pretty sure thats the guts of it... could be wrong tho
Dolphins are so smart that within a few weeks of captivity, they can train people to stand on the very edge of the pool and throw them fish.

Pretty much spot on there ET. However a diesel can run just a catalytic converter like a petrol then you move into the more involved DPF,DOC and adblue systems.
