The University of Idahos entry into the 2010 SAE Clean Snowmobile Challenge (CSC) was a direct-injection (DI) two-stroke powered snowmobile modified to use blended ethanol fuel. The modulated and battery-less direct-injection system used to decrease exhaust emissions and improve fuel economy maintained near stock power output of the engine. Noise from the engine compartment was reduced by custom placement of sound absorbing materials. Pre-competition testing had the snowmobile entering the 2010 SAE CSC competition weighing 507 lbs (230 kg) wet, before adding sound deadening material.
