A three-person team—two of them freshmen—from Clarkson University won the internal combustion division of the SAE Clean Snowmobile Challenge.
Hosted by Michigan Technological University , the Clean Snowmobile Challenge is the Society of Automotive Engineers' newest collegiate design competition. Engineering students from participating schools take a stock snowmobile and reengineer it to reduce emissions and noise while maintaining or improving performance.
All entries in the challenge’s internal combustion division were required to run on biofuel, and most, including Clarkson, chose E85 ethanol. Four schools computed in the zero emissions division, which was won by the University of Wisconsin at Madison .
The challenge began following a ban on snowmobiling in Yellowstone due to the machines’ noise and emissions.
“What you have done is prove solutions are possible,” said Jim Evanoff, an environmental protection specialist at Yellowstone National Park . “We support fully what you are doing.”According to the American Coalition for Ethanol, snowmobile manufacturers listed below have warranty statements that include ethanol (E10) as an approved fuel. Many manufacturers recommend its use to promote clean air in areas of heavy snowmobile use such as Yellowstone National Park.
