Throughout this site we use many technical terms, and given the breadth of readership our site enjoys, sometimes we are remiss and incorrectly assume everyone knows what we are referring to. For those that do not, here are some explanations of the technical terms use.
Fly-Wheel
A heavy disc of metal attached to a rotating shaft which by virtue of its inertia stores some of the energy from a fluctuating torque and enables rotation to continue, thereby helping to maintain a constant speed. In the case of an automobile it is attached to the crankshaft and using some of the energy of the power I stroke enables the crank to continue rotating through the other three strokes. It also provides one driving face for the clutch and an outer ring gear for the engagement with the starter motor.
