  1. 2006 Michigan Tech Clean Snowmobile Matt Prusak - Team Leader Wes Barrett – Vice President

  2. Concept “Design and build a clean, quiet, reliable, high-performance snowmobile that is enjoyable to ride in a wide variety of conditions, and can be operated by a wide range of enthusiasts.”

  3. Outline • Why is the MTU Clean Snowmobile superior to current technology? • Consumer Perspective • High-Performance • Environmental Perspective • Low Noise • Low Emissions • Dealer/Outfitter Perspective • Durable • Low Cost • High Resale Value

  4. Performance - EngineConsumer Perspective • ’03 Honda CBR 954RR • 4-cycle • 4-cylinder • 4 valves per cylinder • Electronic Fuel Injection • 113kW (152 rwhp) in OEM trim

  5. Performance – ChassisConsumer Perspective • Premium suspension components • Fox Float front shocks used • Highly tunable • Rear suspension spring and damping rates modified • Extensive on-trail Calibration • Multiple-rider input for 200 miles • Calibrated for best possible compromise between bump absorption, and weight transfer for a wide range of users, from beginner to expert

  6. Emissions DevelopmentEnvironmental Perspective • Why use a four-stroke engine? • The numbers don’t lie

  7. Emissions Strategy • Team-Designed Exhaust System • Emitec Catalytic Converter Installed • Power Commander Piggyback EFI Modifier • Used to Modify OEM Fuel Map • Significant reductions in tailpipe emissions compared to OEM engine calibration • 96.6% Average Reduction in HC • 97.2% Average Reduction in CO • 93.1% Average Reduction in NOx • Stoichiometric Operating Conditions

  8. Emissions Development

  9. Noise ReductionEnvironmental Perspective How? • Team designed Helical Gearbox • Intake silencer • 2 piece muffling system • Primary Supercritical muffler • Secondary glass pack to absorb high frequency noise • Closed off hood vents • Sound absorbing material in belly-pan • Minimized idler wheels in rear suspension • Made Use of Arctic Cat style Quiet Track Technology

  10. Secondary Muffler Testing Noise Reduction TestingEnvironmental Perspective Selections: • Long Red GP – 83.1 dBA • Good combination of noise and power output

  11. J-192 Field Testing Noise Reduction TestingEnvironmental Perspective Selections from testing: • Covered Silenced Intake – 74.5 dBA • Closed Hood Vents – 73.5 dBA

  12. DurabilityDealer/Outfitter Perspective • Built on a Polaris Pro-X race driven Chassis • Torture tested for over 200 miles on ungroomed trails • Powered by a race proven Honda 954cc High Performance street bike engine • Dyno Tested for over 100 hrs • Constant 10 minute intervals at mode 1 calibration point

  13. Cost AnalysisDealer/Outfitter Perspective • 2006 TICA • Total Implementation Cost Analysis (TICA) of $1346.19 • Coming in at around $9400.00 makes it cheaper than the new 4-strokes when added to price of Stock 600 Polaris • Highly tuned 4-stroke Engine • Consumes Less fuel than stock – Approx. 14 mpg • Maintenance Free • Fouling spark plugs isn’t even considered • Uses no oil, changing oil/filter seasonally
