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. The goal of the multi-fuel engine control team is to complete the development of 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 system last year also was limited in the maximum revs on the engine. The max revs were controlled as a result of the need to use an external electronic ing8ition control unit, separate from the Mega Squirt. As of last year the Mega Squirt did not support coil on plug ignition. However, an expansion board was in development and we were slated to be a beta test site. However the schedule on the ignition unit slipped and the automotive unit had to be used. The 2009 team will need to determine a way of allowing the snowmobile to reach max revs while using the mega squirt engine control unit.
The Phazer will compete in the 2009 Clean Snowmobile Challenge held at Michigan Tech in March
1. Baseline emissions and performance data from the snowmobile including operation on E85, E40 and E10.
