<VV> Catalytic Converter for Corvair

[John Kepler]

Craig is close on the rotten egg smell.  The smell is from Sulfur Dioxide
(SO2) which could be a product of the thermal decay of sulfuric acid
(H2SO4). 

No, it isn't!  The "rotten egg" smell is hydrogen sulfide, H2S which is
formed by the catalysis of HC and residual sulfur in the exhaust.  H2S is
whoppingly hydrophilic, and will readily form H2SO4 by hydrolysis
