| Abstract | From 2001 to 2006, the Michigan Technological University Clean Snowmobile Team successfully implemented highperformance four-cycle internal combustion engines into an existing snowmobile chassis. The team’s complications in past years did not rise from using a four-stroke engine in a snowmobile. Problems arose from the simple fact that all previous engines were originally motorcycle engines which did not have dimensions or configurations consistent with that of a snowmobile engine. This led to difficulties in packaging, drive train modifications, and additional weight. In 2007, the team decided to take a different approach in building a snowmobile for the competition. Instead of spending significant effort on engineering the cohesion between engine and chassis, the team decided to start with a stock snowmobile engine and chassis. Our OEM snowmobile choice for 2007 and 2008 was the 2006 Polaris FST Classic. Polaris released an improved chassis in 2008 in the form of the FST Switchback. The team decided to utilize this chassis due to chassis advancements and packaging advantages over the 2006 Polaris FST Classic. The use of a stock engine and chassis combination allowed for a greater focus to be placed on the implementation and calibration of a flex fuel system. This configuration along with the use of team-designed exhaust and intake systems has made significant reductions in emissions and noise possible. The net result is a snowmobile that is not only environmentally friendly, but also a pleasure to ride. |
