The University of Idaho Clean Snowmobile Team is comprised of undergraduate and graduate students who design, build, and test a snowmobile that then competes at the SAE Clean Snowmobile Challenge. The object of the challenge is to reduce emmisions and quiet the snowmobile while maintaining the reliability and performance of a stock snowmobile. The team has taken first at competition in 2002, 2003, and 2007.
The UICSC team's design involves a high performance snowmobile chassis coupled with a modified Ski-Doo 600 cc H.O. two stroke engine. A direct injection cylinder head was designed and fabricated at the University of Idaho by students. To provide fuel an Evinrude E-Tec direct injection system was adapted for use on the snowmobile. The direct injection and combustion chamber design work together to drasticaly reduce engine emmisions while improving fuel economy. Engine tuning and exhaust after treatment also reduce emmisions. Noise emmisions are reduced through the use of sound absorbing materials and a non-standard exhaust silencer. For 2008 the team hopes to lower noise emissions even further and modify the sled to run on E-85 fuel. The UICSC team's goal is to produce a low-emmision and fuel efficient snowobile while maintaining the performance characteristics that the market demands.
