The University of Alberta Four-Stroke Ski-Doo MXZ-X Conversion 2002-01-2760
The University of Alberta Clean Snowmobile Challenge Team used a modified 2000 Bombardier Ski-Doo MXZ-X for the 2002 Clean Snowmobile Challenge (CSC). A Suzuki GSX-R 600 engine with a custom tuned port fuel injection system and custom exhaust system weree installed to maximize power while reducing emissions and noise from the snowmobile. This design was intended to meet the objectives of the CSC2002 competition which were a 50% reduction in hydrocarbon and carbon monoxide emissions and a reduction in noise to 74 dBA at 15 m (50 ft.) and wide open throttle (WOT). The reduction in emissions was easily achieved through the use of a four stroke engine with fuel injection and exhaust catalyst. The team was unable to meet the noise reduction goal although the entry was significantly quieter than the stock control snowmobile.
