RAPID CITY, S.D. (March 10, 2014) – The South Dakota School of Mines & Technology Clean Snowmobile team took second in the zero emissions division of the 2014 Society of Automotive  Engineers (SAE) Clean Snowmobile Challenge, triumphing in one of Michigan’s snowiest winters in years – the ideal sub-freezing conditions for the SAE design competition.

In the Clean Snowmobile Challenge, engineering students compete in a variety of categories. The internal combustion category aims to reduce emissions and noise and increase fuel efficiency while preserving the riding excitement demanded by snowmobile enthusiasts. The zero emissions category, sponsored by the National Science Foundation, relies on electric snowmobiles to conduct atmospheric research in pristine arctic locations.

“Advances like these are critical to the future of snowmobiling,” said Art Jeffers, acting forest supervisor of the Huron-Manistee National Forest, who represented the U.S. Forest Service at the challenge. “The snowmobiling industry and the clubs have made great strides, and with their sponsorship, the Challenge has been a great way to move the technology forward.”

Next year, the challenge will dedicate a separate category to diesel-powered sleds, as demand mounts for diesel technology education from companies such as John Deere and Caterpillar. Sleds in the challenge will continue to use a biofuel mix based on gasoline and isobutanol, requiring future entries to adapt to a mystery blend fuel recipe that contains an unknown percentage of isobutanol.

Team members are Riley Hosman, an electrical engineering sophomore from Brandon; Bennett Prosser, a mechanical engineering junior from Sturgis; Mathew Daniels, an electrical engineering sophomore from Brooklyn Park, Minn.; Spenser Foster, a mechanical engineering junior from Flandreau; Doug Kadrmas, an electrical engineering junior from Dickinson, N.D.; and Kyle Roe, a mechanical engineering junior from Hayti.

The Clean Snowmobile team falls under the purview of the Center of Excellence for Advanced Manufacturing and Production (CAMP). The center is designed to teach students engineering, science and design skills, as well as the ability to work in teams. Team members design, build, market and raise the money for their projects.
