Easy big guy. I don't think I'm the enviro-nazi you think I am. I was
pointing out (perhaps wrong) the technical aspect of running a hotter
engine. The flaming I expected was on the technical side, not politics.
Politics and internal combustion engines don't mix. Period.

Perhaps someone in the know (*ALL* politics aside) could answer if this
is the case for gasoline combustion. I know this is the case for the
natural gas industrial engines I work on. As much as I don't like it
either, I have to work on engines to bring their emissions down and I
feel that my question was legitimate.

Dammit, this is a technical group, not a political forum and I'm ticked
that my question was construed as such. There I spoke my mind.
