Just to clear things up (as to why I posted the question that way)...
I was debating with a co-worker about diesels. I claimed they were
cleaner-burning than gas engines. He said the extra "junk" put out by them
was offset by the savings in greenhouse gasses. I made all the SAME claims
you did. But, one question of his was what about the carbon? I said it
was harmless, but he wanted to know how to get rid of it. I suggested
scrubbers. (I figured it would be no harder or more expensive to install
than "cats".) Does there exist any designs for a scrubber? (I'd like
to know just to answer his final question.) I convinced him that diesels
are cleaner otherwise.
BTW, (I named my subject "Dirty Diesels" because I knew it would get a reaction
out of people who knew they were cleaner than gas engines and that they'd
read it...)
