Abstract
Clean snowmobile technology has been developed and applied to an existing commercially available snowmobile. The goals of this effort included reducing exhaust emissions to levels which are below the U.S Environmental Protection Agency (EPA) 2012 standard. Additionally, noise levels were to be reduced to below the noise mandates of 78 dB(A). Further, this snowmobile can operate using any blend of gasoline and ethanol from E20 to E30. All of these goals were achieved while keeping the cost affordable. Snowmobiling is, after all, a recreational sport; thus the snowmobile must remain fun to drive and cost effective to produce.
The details of this design effort including performance data are discussed in this paper. Specifically, the effort to modify a commercially available snowmobile using a three cylinder, four-stroke engine is described. This snowmobile was modified to run on a range of ethanol blended fuels using a closed-loop engine control system. Additionally, a new exhaust system which features customized catalytic converter and mufflers to minimize engine noise and exhaust emissions has been developed.
