Don't know if anyone is interested, I came across this on a coal mining forum. Years ago diesels engines were tested and ran on pulverised coal. A couple of links below. Maybe when oil runs out it will be common practice to run cars on coal?

Interesting stuff,I only hope Bernie Ecclestone never here's about it

Not going to do your DPF much good.

Pulverised coal is said to burn cleaner than diesel, might not need a DPF? Black MY2013 SD4 GS Auto, Wood Company Armrest, Freel2 sticker.

I used to live near Didcot power station - that ran on pulverised coal. I wouldn't want to be downwind of what came out of the smoke stack there.

The residue went off in bulk tankers labelled "Pulverised Fuel Ash" and was used to make thermal building blocks. The rest they tipped into a local lake (gravel pit http://www.radley-village.org.uk/ourvillag...ground.htm ) GONE - '07 TD4 GS manual Zermatt Silver

Coal burns much cleaner than any oil, but has a much higher ash content. So oxides of sulphur and nitrogen would be much lower, but your exhaust wouldn't look too clean.

Then coal PF & ash products are so abrasive, you wouldn't suffer from carbon build up too much......
