Wow, what a mess, I had no idea.  Doesn't it make more sense to measure what
comes out of the exhaust?  I would bet that converting a vanagon to electric
'zero emission' wouldn't jibe either -- non original engine.  I do know that
Peter at Tiico has been fighting this stuff for a while, just never knew what
it was.  I, like everyone else, want clean air.  This just sounds ridiculous.
 Some day, we'll use hydrogen.....then comes the subaru hydrogen fuel-cell
swap, Lilley oxygen upgrades, etc.....

Thanks to all who responded.  Especially Scot and Sean who kept it under the
prescribed "150 words or less".
