Engine Driven With Dust
Rudolf Pawlikowski demonstrates a coal dust fueled internal combustion engine that can run on dry coal dust with a small oil ignition charge. Analysts note limited field use due to cost of modifications, but coal dust engines offer fuel flexibility when coal is cheaper than oil.
