Vegetable oil.

Rudolph Diesel designed his engine to run on vegetable oil, with
peanut oil and cottonseed oil considered prime candidates. At the
very, very, beginning it was all about bio-diesel.

Not that coal dust might not have been used at some point, but I
wonder how a dust could be injected into a cylinder of compressed air?
A liquid seems more ideally matched to the technical requirement.



I think Wayne is correct, although the coal dust approach didn't work out.
