Catalytic Converters for Small engines

[willing@mts.net]

Given the extraordinary amount of pollution produced by small engines,
you'd think that cat converters would be more common by now. I believe
there's US legislation requiring serious reduction in pollution in new
machines by 2007, but I'm not sure. My research did turn up lobbying
efforts by Briggs and Straton to defeat such legislation in California
a few years back - way to lead us forward, B&S!

Anyway I've found a couple of links for companies who claim to be
working on aftermarket cat converters for small engines, but so far
nothing actually shipping. Anyone know of a company who's doing this
for real?

In a related question, a CBC TV news item a while back featured a guy
in the maritimes who's been custom-building these things for just this
purpose, and had them tested and proven effective by some Canuck gov
department, but he can't seem to get anyone interested in funding
manufacture. I'd love to have the guy's name.

I'm sure it will come. I [pollute more cutting my grass that my drive to
work each day.

Biggest problem I see is cost. Gone will be the $89 weed trimmer and $99
chain saw.

Auto industry fought it too, but turns out we have many side benefits.
Leaded gas is gone along with spark plugs that fouled in 10,000 miles or
less, and oil changes every 1000 miles.

Small engines are very dirty to start with. All those hydrocarbons
would kill the typical converter quickly. You need to start off with fairly
clean exhaust to start with and that means good temperature control, which
is very difficult to do with an air cooled engine (Which is why you no
longer see air cooled engines on automobiles.) and tight ignition timing and
fuel control (computer controlled fuel injection) So with the needed
equipment your next push lawn mower may cost a few thousand dollars.

Actually a lot of improvement can and has been made. Many are much less
dirty than they were 10 years ago, but you are right, more can be done.
However until people demand it, the industry will keep lobbying government
and it will not happen.
