A flywheel is an important component attached to an engine, and its primary function is to store rotational energy, thus maintaining smooth operation. The main purpose of a flywheel is to help the engine at its “dead points,” which are critical moments in its cycle when the power output from the pistons of the engine is at its minimum or zero. These dead points usually happen between changes from one kind of stroke in the engine cycle to another, like from the power strokes to the compression strokes.
The flywheel can absorb energy during the active phases of the engine’s operation and then release it at the dead points, ensuring that the engine continues to run smoothly. This energy storage and release mechanism helps minimize fluctuations in the engine’s speed, leading to more consistent power delivery and reducing the likelihood of stalling.
In addition, it maintains steady angular momentum, which is important to stabilize the engine’s rotational motion. It doesn’t increase or decrease the speed or energy of the engine directly but makes the overall efficiency and reliability of the system by addressing the problems that arise from the dead points in the engine cycle. So, flywheels have a very crucial role in the optimization of an engine.
