1. University of Minnesota Clean Snowmobile Team

2. Overview Our Team Goals Design Objectives Development Process Current Snowmobile

3. Goals Increase Membership o 15 Members o 750% Growth from last year Increase Resources o Shop Space o January 25 th, 2016 o Equipment acquisitions o 5-gas emissions analyzer o Dataq Gain sponsorships Attend competition

4. Design Objectives Catalyst o Heraeus 3-way catalyst Belt Drive o Reduce noise o Reduce rotating mass PE3 ECU

5. Emissions Control EmissionsPercentage/ppm HC1.13% CO 2 2.0% CO3.05% NO x 40 ppm Data at idle 3-way catalytic converter o Heraeus o Implemented on snowmobile o BASF o Testing 2-stage catalyst system Supplier Catalyst Wash Coat Heraeus 1:20:1- Pt:Pd:Rh 50 g/ft 3 BASF 2:9:1- Pt:Pd:Rh 60 g/ft 3

6. Belt Drive System Reduces Rotating Mass o 1.1 kilogram reduction Eliminate Chain Bath o Potential noise reduction

7. Engine Control System Stoichiometric Air/Fuel Ratio PE3 ECU Skip-tooth timing wheel

8. Summary MSRP: $10,225 Electrical Component Issues Improvements for 2017 Competition o Better Project Management o Greater Industry Support o Increase Testing
