Development of a Snowmobile to Address Concerns of Exhaust and Noise Emissions

This paper describes the design strategy and procedure followed by the University of Waterloo's Team Eco-Snow in order to participate in the Clean Snowmobile Challenge 2001. The team's objectives are to engineer a clean, quiet snowmobile that provides recreational users with a more environmentally responsible vehicle while maintaining or exceeding the performance of current production snowmobiles. The design strategy followed includes the active development of two separate alternatives powered by both a two stroke and a four-stroke engine. Each of these solutions was analyzed and modifications performed to meet the goals of the competition and of the team. Finally, the extent to which each alternative met these goals was evaluated.
