For this event the Students completed a technical document written in SAE format that described in detail what their goals were for the event and how their modifications to their snowmobile accomplished those goals.
The Technology Implementation Cost Assessment (TICA) summaries the cost that a manufacture would have to make to modify the existing snowmobile if they were to produce 5000 units.
Following the EPA emissions guidelines for 2012 the team must test their snowmobile for Hydrocarbon, Carbon Monoxide and Nitrous Oxides in grams per kilowatt hour (g/Kw-hr) using laboratory grade instrumentation and a DYNO-mite direct couple dynamometer.
The Students are scored on a ten minute presentation that explains what was done to the snowmobile and why modifications were made the way they were. A five minute question and answer period with the judges follows the presentation.
This event tests the teams snowmobile in a one hundred mile endurance event to judge durability along with fuel economy.
The snowmobile is tested in a 500 foot wide open acceleration test for time.
Handling is scored two ways the first being a timed course where a student will ride the snowmobile over a specified course based on time, the second being a professional rider will evaluate the ride characteristics of the snowmobile.
This event will test the ability of the snowmobile to start after sitting outside overnight and must start within twenty seconds and move 100 feet in the first 120 seconds.
Here the snowmobile will be tested with an accelerometer for shock input to the rider and also for vibration to the rider by ISO standards.
The team constructs a visual display giving information on the testing done, the strategy taken, and the engineering applied to the snowmobile. It also is an opportunity for question to be asked to the team about their snowmobile.
The purpose of this event is to measure the noise given off by the snowmobile under full throttle under SAE J192 specifications and also by judges for subjective noise quality.
