[Vehicles] Gunpowder Engines and Stirling Engines

[Ulzgoroth]

From the paper intro I wonder whether that might be the thermite-spiked gunpowder they mention...

But you repeat yourself. Fuel air explosives are thermobarics, and there's really no difference between a fuel-air bomb and an internal combustion engine cylinder ignition except for confinement and perhaps compression. Which, if the confinement failed, would only make the whole thing more dangerous.

I wouldn't want anything to do with an internal combustion engine that tried to run on powdered magnesium/oxygen burning, granted...

Fuel air explosives, of course, do work by having the fuel very thoroughly mixed with the oxidizer. Typically achieved quickly by using a small explosive to blast the fuel out into the surrounding air before igniting it.
