Clean Snowmobile Piggyback

Background:

The objective for the multi-fuel engine control team is to develop a system which is capable of operating the snowmobile with ethanol or gasoline or any mix of the two fuels.  This system must be robust and demonstrably able to run 100 miles prior to the competition.  The piggyback must demonstrate improved emissions using the catalytic converter that is already on the Yamaha snowmobile.  One of the goals in this project is to minimize the HC and NOx emissions for a total minimum percentage of emissions required for the greatest amount of design points.  (CO emissions are also considered in the test, but are weighted less than the HC and NOx emissions levels). 

Milestones

  • Check fluids and run sled: September 7th, 2007
  • Ensure gas is available order new exhaust emissions tester : September 14th, 2007
  • Demonstrate ability to cool sled on dyno: September 14th, 2007
  • Dyno test sled with MegaSquirt, verify integrity of engine, dyno results plotted: September 18th, 2007
  • First web page goes live with introductory page and menu on left. Page must include resumes, individual photos and milestones: October 12, 2007, 2 pm.
  • Demonstrate the ability to change the program on FM unit: October 23, 2007
  • Wiring redesigned and installed on Yamaha that allows Mega Squirt to be disconnected using industry or race quality connectors and moved between demo board and snowmobile.  Wiring should be fail safe and unable to be connected in a manner that will result in damage to unit or sensors: November 7, 2007
  • Milestone review: November 7th , 2007
  • ECU installed in Yamaha with brackets and complete drawing package: November 13, 2007
  • ECU installed and operating engine on dyno, needs not run well!: November 20, 2007
  • Retest snowmobile on dyno for emissions and fine tune performance.  Program at least four curves that show the effect of ECU on emissions: November 27, 2007
  • Draft Midterm Report: December 4th , 2007
  • Order second ECU for programming back up: December 7, 2007
  • Connectors installed to make ECU changeover possible and demonstrate a less than 10 minute ECU change: January 26th , 2008
  • Attend and present snowmobile at least two events, (for example Caribou Winter Carnival/Snowmobile Festival was Feb. 16-26 in 2007 and the International Snowmobile Festival was February 3-5 in 2007). Demo must include exhaust emissions analyzer and drive by test with sound level meter with a fully operational snowmobile. (March 1st , 2008)
  • Lab Cleanup: Maine Day, May 2nd , 2008
