emit significant amounts of pollution? Yes!
Current (2001) production snowmobiles mostly use two-stroke engines that
produce significant amounts of unburned hydrocarbons, carbon monoxide, and
particulate matter emissions.
Snowmobile emissions are not yet regulated by any federal agency.
The best estimates available that compare snowmobile emissions to average
automobile emissions conclude that a traditional snowmobile produces 10 to
70 times more carbon monoxide and between 45 and 250 times more unburned hydrocarbons
than an average automobile.
Two-stroke engines used in snowmobiles are sometimes
the same engines used in personal water craft (PWC) like jet skis, and all-terrain
vehicles (ATVs) with different air intake and exhaust systems to adapt for
water use. However, the way these engines are used in PWC is considerably
different, and these operational differences change the emissions and emission
content. Temperature difference is one large variable. PWC seldom operate
at temperatures below freezing (0 C) where snowmobiles typically operate
at colder temperatures when all engines want to run rich. Colder temperatures
favor the production of carbon monoxide and warmer temperatures favor the
production of unburned hydrocarbons.
