Project: Yamaha
Engine Mapping and Controls

Background:

In 2006 the University of Maine Team started to work on a sled based on a Yamaha Phazer snowmobile.  This project focuses on the improvements to this sled in the emissions and performance areas.  In 2008 the snowmobile competed in the clean snowmobile competition.  As a result of some problems encountered with the fuel system, the team had the worst finish in the history of the UMaine CSC team.  These issues were mainly addressed in the 2009 competition, however the lack of complete tuning of the engine resulted in a modest result for th team.  The other teams are getting better, and UMaine needs to step up to the plate.  The goal of the multi-fuel engine control team is to optimize a system that is capable of operating the Phazer on any mixture of ethanol and gasoline. The engine has been adapted to run on a well known aftermarket ECU called Mega Squirt.  This system is used with a inline fuel sensor from Bosch which senses the mixture of ethanol and gasoline.  The output of the flex fuel sensor is input to the Mega Squirt and allows the sled to be mapped to run on any amount of Ethanol.  However, it is necessary to optimize the engine fuel map to minimize emissions while still retaining good fuel mileage for each fuel mixture. 

The Phazer will compete in the 2010 Clean Snowmobile Challenge held at Michigan Tech in March

Deliverables

1. Baseline emissions and performance data from the snowmobile including operation on E85, E40 and E10.

2. Initial map for E85, including sources and winter mix information

3. Performance and emissions data for all possible mixes of ethanol

4. Demonstration at a public event in Maine

5. Performance at competition

6. Documentation of the efforts in the form of a design report and presentation for competition and for class.
