New engine design?
Anybody know anything about this engine?
Technology Review: Ultra-Efficient Gas Engine Passes Test
Seems like they're describing a diesel, but without the compression.

First I heard of that engine, sounds alot like diesel and they referenced diesel as being simmilar but not the same.
Bigger question I have is if we would see a conversion of this for older engines. Holley sells 4V TBI assemblies as well as true EFI. Wonder how long before this comes out. If it maintains engine performance and bumps fuel efficency up to that 64 MPG highway then I will gladly accept the new technology.

Sounds interesting, it should be more efficient that's for sure. Sounds like it has no throttle plate which gets rid of the primary pumping loss in a gas engine, although they do mention basing it off current diesel tech so it probably does still have fairly high compression.
It seems to be a step after stratified charge, eliminating the spark ignition and combining everything to one combustion chamber. I do have to wonder what they heat the injectors with though.

I've been following this for a while now as part of my Biodiesel research. This engine will burn most any liquid fuel. Super-critical fluids are a strange bunch. The reference to Diesel technology is the High Pressure injection system similar to the powerstroke engines. You can get a lot more info here: Transonic Combustion | Ultra-high Efficiency Fuel Injection Systems
From what I've been told it would be adaptable to older engines.
