The Brown's Gas crap is, for lack of a better word, retarded. I hate the name "Brown's Gas". It sounds like "Brown Note".

Anyways.

Apparently, there is a field of research called hydrogen injection, which is supposed to allow engines to idle at superlean mixtures. But right now it's experimental. The idea is that a small amount of hydrogen in a running engine allows the engine to save fuel in non-load modes.

But nothing about on a engine while running...yet. And no Brown Gas.

We'll see.
