The SAE Clean Snowmobile Challenge 2002 - Summary and Results 2002-01-2755

In response to increasing concern about snowmobile noise and air pollution, Teton County Wyoming Commissioner Bill Paddleford and environmental engineer Dr. Lori Fussell worked with The Society of Automotive Engineers (SAE) and the Institute of Science, Ecology, and the Environment (ISEE) to organize an intercollegiate design competition, the SAE Clean Snowmobile Challenge (SAE CSC).

The goal of the SAE CSC was to encourage development of a snowmobile with improved emission and noise characteristics that does not sacrifice performance. Modifications were expected to be cost effective and practical.

The third year of the competition, the SAE CSC2002, was held in Jackson Hole, Wyoming from March 23 - 29, 2002. Major sponsors of the SAE CSC2002 included Flagg Ranch Resort, Montana Department of Environmental Quality, Wyoming Department of Environmental Quality, International Snowmobile Manufacturers Association, Teton County Wyoming, United States Department of Energy, and ISEE.

Teams participating in the event competed against each other in the categories of emissions, fuel economy/range, noise, acceleration, handling, cold-start, hill climb, engineering design paper, oral presentation, cost minimization, and static display. Points were awarded to teams based on their performance in each of the events.

Kettering University and the University of Idaho tied for first place overall at the SAE CSC2002. Kettering University's entry featured a 659cc four-stroke turbocharged engine with electronic fuel injection (closed loop control) and three-way catalytic aftertreatment. The University of Idaho's entry featured a 750cc four-stroke engine with electronic fuel injection (open loop control) and three-way catalytic aftertreatment. Both first-place entries were successful at reducing noise and emissions while simultaneously improving fuel economy and maintaining adequate performance. They were reliable snowmobiles, successfully completing and passing all competition events.
