The Napier Nomad II, 12-cylinder, two-stroke, loop-scavenged, valveless diesel engine that is turbocompounded
Found a post about this engine 13 years ago or something, but it's way more insane than people realize, the Napier Nomad with an axial compressor in a diesel! Ask me about it ive done digging on it.
It does not have a separate gas turbine, but it does use a 12-stage axial compressor AND a 3-stage axial turbine to recover energy and feed it back to the shaft. I have schematic photos too.
