Snowmobile for Extremes

After watching so many videos on winter camping which utilized snowmobile for transportation, I decided to come up with my own design to address some of the issues with current models. Snowmobiles are small vehicles that allow so many modifications based on the model. My proposed features would be provided by the manufacturer and the design would be optimized to accommodate these features seamlessly compared to an aftermarket modification.

The main objective of my design is to improve the operability of the snowmobile in extreme weather.

To address the cold start problem of the engine I propose the use of super capacitors instead of classical car batteries. The batteries are only used for startup. Once the engine starts, the dynamo supplies the necessary electrical power to the rest of the vehicle. A specially designed super capacitor would have better low temperature rating and can be charged very fast in case of depletion. There will be a pull rope emergency electric generator to fast charge the capacitors in extreme colds.

There will be an internal Webasto heater that can be started by a piezo igniter to warm the engine block and the super capacitor in extreme cold. Once the engine starts it would be shot down.

Some of the air cooling the engine block would directed to the dash of the snowmobile to warm the drivers face. This would also defrost the frozen windshield to improve visibility. The handlebar grips would be electrically heated to prevent the fingertips from freezing in extreme cold. The seats will be heated by a heatsink attached to the exhaust pipe.

There will be a winch in front of the snowmobile that is powered by the engine. It would allow the snowmobile to tow itself in case of emergency.

The dashboard of the snowmobile will only have LED indicators which keep operating even at extreme cold compared LCD screens. There will be a GPS receiver on board which would only show distance information in X-Y coordinates between the selected prerecorded points and the current position. This simple design would be more reliable in extreme conditions compared to GPS systems with complex software and LCD screens. In case of getting lost in snowstorm, the home location, last turn on location or pre-recorded location would be recalled by pressing large memory buttons that can operate with large glows.

Finally, the headlights would have high illumination LEDs with multiple focusing options.
