The University of Idaho's entry into the 2006 SAE Clean Snowmobile Challenge (CSC) was a second-generation gasoline direct-injection (GDI) two-stroke powered snowmobile. A modulated and battery-less direct-injection system was used to decrease exhaust emissions and improve fuel economy without reducing the power output of the engine. The team added a reduction catalyst designed for a two-stroke to the exhaust silencer to further reduce exhaust emissions and noise. Under-hood noise was targeted by using sound absorbing materials and a sealed hood. Chassis noise was addressed by using a spray-on rubberized material that absorbs vibrations transferred through the chassis. The snowmobile entered into the 2006 SAE CSC competition was lightweight, easy-to-ride, powerful, fuel efficient, and had reduced exhaust emissions.
