A diesel engine will run on a slurry of coal in jet fuel -- but given the present state of the art, not for very long. Researchers at Virginia Polytechnic Institute investigated slurry operation using a one-cylinder research engine fitted with special pressurized fuel delivery. Their results show fuel consumption and power characteristics comparable to conventional diesel operation, but with accompanying problems of fuel system clogging. If injection pump and nozzle could be made compatible with pulverized coal, the latter might replace as much as 30% of liquid fuel weight. The mixture used by VPI researchers consisted of finely pulverized coal (around 2 micrometer particle size) suspended in Jet-A fuel with a proprietary emulsifier. The coal was obtained from a solvent refining process known to yield extremely low levels of sulfur and ash.
