The DPF does eliminate most of the diesel particulate but what it does produce is exceptionally bad for you.

With a non emissions controlled diesel the particulate is big, from 20 to 250 micron is what I am hearing. You see it you smell it and react to it you don't breath it in, unless you really like the smell of burned diesel.

So non-controlled diesels create only large particulates and controlled diesels only create small particulates?

Or...

Non-controlled diesels create all sizes of particulates, while controlled diesels filter out most of the large particulates?

If the latter, then do non-controlled diesels create less, more, or the same amount of the small particulates as controlled diesels?
