Energy Profile

This section outlines the energy conversions, starting with the translational mechanical motion applied by the user and ending with the rotational mechanical energy that is sent to the gear train and ultimately spins the auger. See Figure () for a graphical explanation to aid in understanding the subsequent paragraphs which further describe the conversions taking place.

By drawing on the pull-start mechanism, translational mechanical energy is created. This cord is wrapped around the crankshaft axle such that when the chord is pulled, the crankshaft is rotated, converting the translational energy to rotational energy. As the crankshaft rotates, it pushes the piston upwards, towards the spark plug, converting the rotation back into translational energy. In the case of the electric start, the spark is supplied directly from electrical power.

At this point in the process, chemical energy is introduced to the system in the form of gasoline. The gasoline reacts upon the piston striking the spark plug which provides the initial energy to power the reaction. This chemical energy then continues to drive the motion of the piston due to the great amount of pressure it generates. In this step, chemical energy is being converted into translational mechanical energy. As the piston is being driven downwards, the crankshaft is rotated, which converts the translational mechanical energy of the piston into rotational mechanical energy of the crankshaft. From here, the mechanical energy can further be manipulated to displace the energy to the auger where it can be used to propel the snow.
