Abstract:
The technical objectives of the Clean Snowmobile Challenge 2000 are to modify a snowmobile to reduce the hydrocarbon, carbon monoxide and noise emissions by 50%, 25% and below 74 dB at 50 feet, respectively, while maintaining or exceeding current performance with a 500 cc two-stoke or 800 cc four-stroke. CSC2000 was the first of its kind competition held by the Society of Automotive Engineers. To meet these goals, the Colorado School of Mines team installed a dual-port fuel injection system, automotive catalytic converter, and noise absorbing foam on the 1997, 488 cc, air-cooled two-stroke Polaris Indy snowmobile provided.
