Nice description of this new 2-stroke, double opposed boxer layout Diesel engine. I also like piston ports, no camshafts or conventional valves to deal with. With DARPA funding this and DOD interest, it could become a reality in military vehicles. Power to weight and powerplant volume (footprint) looks to be outstanding, if it goes, can you imagine the trickel-down of this design for cars?
