Solutions - Clean Snowmobile Challenge

Overview

Airborne Rider

In 1999, in response to increasing concern about snowmobile noise and air pollution in environmentally sensitive areas, Teton County Wyoming Commissioner Bill Paddleford and environmental engineer Lori Fussell worked with the Society of Automotive Engineers (SAE) to form and organize a new intercollegiate design competition, the SAE Clean Snowmobile Challenge 2000 (CSC2000).

The goal of the competition was to develop a snowmobile with improved emissions and noise characteristics that did not sacrifice performance. Modifications were expected to be cost-effective and practical.

Events scheduled to take place during the CSC include emission testing, acceleration event, hill climb event, cold start testing, noise measurement, fuel economy/range event, and oral/written design.

The Clean Snowmobile Challenge 2000 (CSC2000) was held in Jackson Hole, Wyoming, and parts of Yellowstone and Grand Teton National Parks from March 20 through 31, 2000. Seven teams from participating universities competed against each other in the categories of emissions, fuel economy/range, noise, acceleration, handling, cold-start, hill climb, engineering design paper, oral presentation, and static display. Team were donated a 1997 used 500cc fan-cooled Polaris snowmobile to modify. Points were awarded to teams based on their performance in each of the events.

The CSC2011 was held in March 2011 at the Keweenaw Research Center at Michigan Tech, Houghton, MI. 

Pennsylvania's Clarkson University took top honors at the 2011 challenge. The full slate includes awards for zero emissions and overall performance.

The State University of New York at Buffalo (UAB) won the first place CSC2000 event with a snowmobile featuring a Polaris 500cc four-stroke engine and catalytic after-treatment. This first-place entry was successful at reducing noise and emissions while simultaneously improving fuel economy. However, it did experience some loss of performance capability.

The University of Waterloo took second place in the CSC2000 with a snowmobile featuring an advanced two-stroke engine and catalytic after-treatment. The Waterloo entry significantly reduced emissions while simultaneously improving performance and fuel economy. However, noise from this entry did not meet competition standards.

Through the CSC2000, a first step was taken to solve the noise and emission challenges presented by current technology snowmobiles. Although many CSC2000 participants would have benefited from additional development time, the results from the first year of the Clean Snowmobile Challenge Collegiate Design Series clearly demonstrate that the noise and emission problems associated with traditional snowmobiles can be solved through advances in engine, noise control, and emission control technology.
