Making the Connection: The University of Idaho Clean Snowmobile 2001-01-3656

The goals of the 2001 University of Idaho Clean Snowmobile team were to reduce snowmobile exhaust and sound emissions while maximizing fuel efficiency and performance. The competition snowmobile consists of a four-stroke BMW K75RT motorcycle engine mounted into a 2001 model ArcticCat SnoPro chassis. A special motor mount was designed to attach the engine to the chassis, and special carriage developed to match the primary clutch to the engine. A custom exhaust system consisting of a single stage catalyst and muffler was designed to control hydrocarbon and noise production. Modified electrical and fuel pumping systems were implemented to maintain the stock fuel injection system.
