Liquid Piston Engine
« on: December 09, 2018, 02:00:05 pm »
Liquid Piston engine.  The name seems to be a marketing hook but it may relate to the way fuel/air is injected into the rotary piston as a delivery path to the combustion "nooks" built into the main housing.

They seem to be progressing slowly but steadily and are targeting military/UAV applications as commercial/automotive markets are resistant to new engine architectures and require serious financial backing.

Phase II DARPA contract for a diesel 40HP UAV engine starting at 4:30 mark.

At 1:29 it says '4-stroke HEHC cycle' - to me it looks like a 2-stroke cycle. Maybe I misunderstood that first clip?
