wow. I may get back to read the rest of the post, I stopped at "bsfc" (what in heck is that?!)
and ended up browsing half the universe.
interesting engine this one:
Controlled Combustion Engine - Wikipedia, the free encyclopedia
never heard of that either.
rotax, benz, crazy 5 main...never heard of a "revetec"..
the bsfc can be changed dramatically through compression and that brings noise. I found a v8 after tearing it down, at 9:1 only used less than the top third of its cylinder (heat marks in the cylinders, engine was maybe 20 years old), I then learned a monster can come from the same engine if to step up the heads to 10:1...and not many like it, as far as regular driving and true comfort, lack of vibrations come with lack of efficent. Manufactures love this, they can babble all day long about longevity by barely running them, using weak stuff. It's called lard ass of laziness, I mean capitalist.
it is the reason alot of legend engines have left, from 3 main boxer to simple v8 diesels to even a 396 chevy (non-siamesed bores) the potential for outrageous power from thier fuel...and they killed production for capitalism.
I gotta sunscribe to this thread and wander off finding definitons of the rest of the post sometime.
