Flywheel and Governor in Engines
Flywheel and governor are important components of an engine. Let us understand their functions in detail.
Flywheel:
A flywheel is a rotating disk that stores energy and smoothens the torque fluctuations during a cycle. It is connected to the engine's crankshaft and rotates with it. The flywheel's inertia provides a constant force that reduces speed fluctuations during a cycle for a constant load. This is because the energy stored in the flywheel keeps the engine from slowing down during the power stroke and speeds it up during the other strokes.
However, a flywheel does not control the mean speed of the engine if the load changes. This means that if the engine's load increases or decreases, the flywheel's effect on speed fluctuations remains the same.
Governor:
A governor is a device that controls the speed of an engine. It regulates the fuel or steam supply to the engine to maintain a constant speed under varying loads. The governor senses the engine's speed and adjusts the fuel or steam supply to the engine to control the speed fluctuations during a cycle for a constant load.
Moreover, a governor also controls the mean speed of the engine if the load changes. When the load on the engine changes, the governor senses the speed change and adjusts the fuel or steam supply to maintain a constant speed.
Conclusion:
In conclusion, a flywheel reduces speed fluctuations during a cycle for a constant load, but it does not control the mean speed of the engine if the load changes. On the other hand, a governor controls speed fluctuations during a cycle for a constant load, and it also controls the mean speed of the engine if the load changes.
