It would seem to me, mind you, I don't know my ass from ice cream about
this sort of thing, but it seems to me that all it would do is dilute the
emissions, by making them hotter. Less particles of [whatever it is that
comes out]= lower emission count at the testing station.

I'm probably wrong, though.
