Clean Snowmobile Competition Background
In recent years the operation of
snowmobiles in National Parks such as Yellowstone has fallen victim to
heated debates. Typical snowmobiles utilize two-stroke engines due to the
benefit of their light weight yet high specific power output, however, these
engines are at the root of the conflict. Due to their construction and
operation they tend to emit high levels of un-burnt hydrocarbons (UHC) and
high frequency noise compared to a similar sized four-stroke engine.
Project Outcomes
Design, model, manufacture, and test a
system that will minimize the emissions and noise of the University of Idaho
Arctic Cat 600 cc two-stroke direct fuel injection (DFI) system following
the spirit of the 2004 Clean Snowmobile Competition (CSC).
