Flywheel and Governor Difference
摘要
TLDRThis video provides an in-depth discussion on the differences between flywheels and governors. A flywheel is a heavy rotating device that helps minimize speed fluctuations by absorbing excess energy during torque production. While it's not necessary for all engines, it is used in fabricating machines and systems with cyclical input torque variations such as four-stroke engines. On the other hand, a governor is essential across all engines as it regulates speed by controlling fuel supply in response to load changes. The moment of inertia of flywheels is much larger compared to the lightweight governors. Each plays a distinct role: the flywheel handles energy fluctuations, while the governor maintains a steady mean engine speed by adjusting the fuel flow.

This video discusses the differences between a flywheel and a governor. A flywheel is a heavy rotating device that helps reduce the fluctuations in energy caused by speed variations, whereas a governor is a speed control device that adjusts for speed variations due to load changes. Unlike a flywheel, which doesn't control speed fluctuations due to load variations, a governor regulates fuel supply to maintain engine speed. Flywheels are not necessary in all engines, but governors are. Flywheels act like a razor wire to store excess rotational energy, whereas governors regulate fuel to control mean speed. Flywheels have a large moment of inertia while governors have a small one. Flywheels limit speed fluctuations during each thermodynamic cycle, while governors keep the engine at a specified speed limit by adjusting fuel flow. Flywheels are used where input torque fluctuates, such as in four-stroke engines, while governors are used where constant speed is required. Flywheels are applied in engines, fabricating machines, and punching machines, whereas governors are used specifically in engines. The video emphasizes the applications and distinctions between the two devices.
