ABSTRACT The University of Minnesota -Duluth Clean Snowmobile Team the Snowdawg's has redesigned a high performance snowmobile with reduced noise and emissions and improved fuel economy to compete in the 2014 SAE International Clean Snowmobile Challenge. A 2014 Arctic Cat ZR7000 LXR was used as the base model. The snowmobile was redesigned to run on a mixture of iso-butanol and gasoline with the addition of a GM flex-fuel sensor and a Performance Electronics standalone ECU. For the improved emissions, a 3-way catalyst from Heraeus was used. To reduce noise output, a quiet track was installed and the exhaust chamber was redesigned. To improve fuel economy, a bearing roller drive sprocket was designed and the reverse was removed. With the addition of these technical features, the snowmobile will surpass industry standard expectations and improve the overall riding experience.
