Re: Yunick's Hot Vapor Engine in the new Hot Rod, a must read!
Here's what I DO know:
The OEM's are investing millions (maybe even billions) on adiabatic engine technology, and have been for many years. So there's SOMETHING to the concept. I have no clue if Smokey made it work or not.
Also, I suspect that one of the big problems is NoX production. NoX is the result of temp and time ((the period of time the ignited mixtures spends in the combustion chamber), and pressure. Increase any of the above and NoX formation increases. Seems like this engine would be a NoX generator and NoX if tough to control and to treat out of the exhaust stream (hence, EGR). So I'm thinking this is a big issue for this technology but I haven't seen any actual emissions values from this system.
All that said, Smokey was one smart dude and I'll wager that he DID get the car to run and it may have achieved some or many of the stated claims. Does that equate to a viable production engine - maybe or maybe not.
