The University Of Alberta Four-Stroke Snowmobile Conversion 2001-01-3659

The University of Alberta Clean Snowmobile Challenge Team modified a 1998 Polaris XCR 440 Snowmobile to compete in the 2001 SAE Clean Snowmobile Challenge (CSC). A modified fuel injected four-stroke Suzuki GSX-R600 engine and a custom exhaust system were installed to reduce the emissions and the noise emitted from the snowmobile. The objectives of the CSC competition were to reduce the hydrocarbon emissions by at least 50% and emitted a noise level below 74 dBA at 50 ft and at wide open throttle (WOT).
