Development of a Flex-Fuel, Two-Stroke, Direct-Injection Snowmobile for Use in the Clean Snowmobile Challenge and National Parks Grant uri icon

Overview

abstract

  • Due in part to stringent noise and air pollution control measures recently imposed on snowmobiles by the US National Park Service, the Society of Automotive Engineers (SAE) instituted a student competition called the Clean Snowmobile Challenge (CSC) in 2000. The competition is designed to encourage the development of a snowmobile that will meet or exceed specific required pollution and noise control measures, while maintaining or improving the snowmobile’s performance. The objective of this project is to produce a snowmobile that will meet the criteria for the 2009 CSC, which requires that snowmobiles be flex-fuel (i.e., able to run on any mixture of gasoline and E85, or 85 percent ethanol). The snowmobile has a modified stock chassis with a drivetrain designed to minimize sound production and maximize power transmission. The power plant for the 2009 University of Idaho snowmobile is a smaller stock two-stroke engine which has been retrofitted with direct fuel injection. This engine and basic snowmobile have been proven with a CSC first place showing in the 2007 competition and a second place in 2008 and will be modified to be flex-fuel. The team will continue to use graduate mentors as leaders for this primarily undergraduate competition team.
