The Pyréolophore was a French internal combustion engine patented in 1807 by Claude Niépce and Joseph-Nicéphore Niépce. It was used in 1806 to power a boat on the river Saône.

One version was fuelled by expensive lycopodium powder, but a blend of coal dust and resin was also used.

For much more information, see Wikipedia entry for the Pyréolophore.
