Letting it rattle around some more, I think what doesn't seem right is the claims of fuel economy increase. Going from 22MPG to 60MPG? Uh, yeah, if that was possible why wouldn't the manufacturers be all over it? Probably the vast conspiracy to keep us all suckling at the teet of crude oil. OK, there might be some of that, but at least one manufacturer would buck the system and try to corner the market. Color me very skeptical. There just isn't that much energy left in the exhaust, certainly not enough to see 300% increases in economy. Even an old 22R-E or 3FE uses an O2 sensor and is trying to stay close to stoichiometric balance and our engines already do some of this with EGR, which helps with burned HC.
