Diesel Air http://www.dair.co.uk/
British company with a two cylinder four piston Jumo style two stroke. The website has not been updated in 6 years so not looking good.
Zoche Aero Diesel http://www.zoche.de/
Two stroke diesel in radial format. Four con-rods attach to one crank pin. No master rod needed.
Dry sump with small blower and turbo. Original used the small blower as compressed air starter. 4 cylinder single row or 8 cylinder double row. 2.5 litre made 150bhp @ 2500 rpm. Rev that to car diesel speeds and it would be making 100bhp per litre. Add modern controls and it could double again. Not with aero reliability (of course) but the potential is there.
The company used a lot of EU funding then went quiet. Sad because it sounds great on the test bed.
Delta Hawk https://deltahawk.com
Inverted V four two stroke supercharged and turbo diesel.
3.3 litre 180BHP There is no crank case compression so "bottom" end is dry sump lubricated. Air is blown direct into the cylinders from blowers. the same ides used in a car engine would be extremely powerful. Aircraft sacrifice all out power for uber reliability.
Same power potential as the Zoche and they seem to have gone into production.
