  • the function of a flywheel is to store energy ( Kinetic energy inform of rotational energy) when there is excess energy produced by the system and to release the energy to the system whenever the system is in need.

  • Fly wheel is like energy storage device and release when it is required

  • Its just like a battery of mechanical energy.... It stores the energy during the power stork... Supply the stored energy during compression of the air... The fly wheel stores the energy as kinetic energy... Because each and every particle are capable of storing energy... For example the fan rotates after we switched off... Reason is storing of kinetic energy....

  • Flywheel is used to store extra energy in it and when energy is required flywheel supplies it.

  • A flywheel is essentially a heavy wheel which is used to store energy when it is in excess and release energy when demanded. The excess energy developed during power stroke is absorbed by the flywheel and releases it to the crankshaft during other strokes in which no energy
    is developed, thus rotating the crankshaft at a uniform speed. A little consideration will show that when the flywheel absorbs energy, its speed increases and when it releases energy, the speed decreases. Hence a flywheel does not maintain a constant speed, it simply reduces the fluctuation of speed.

  • A flywheel is basically nothing but a storehouse of energy. It has very high moment of inertia, which is why once it gets into motion, it is almost as though it is in perpetual motion. If you've lived in India, you might have seen the machine a local sugarcane juice vendor uses. He will mechanically rotate a large wheel which has a weight attached to it in a manner that when the wheel is in motion, it becomes practically unstoppable. After that, as he passes the sugarcane through the gears, they literally just pull the tough canes through, wringing out the juice from them. That's nothing but a flywheel in action.

    Now, a typical automotive engine will have four strokes, only one of which generates power. All the other three strokes take power away from the crankshaft. So, while in theory, the engine will run because of compression and de-compression, the energy to keep it going is generated only during one cycle, that's the power stroke. What a flywheel does is, it stores this energy, and keeps the engine going through the other strokes by providing the energy back. Diesel engines require more energy through the other strokes owing to higher compression ratios. That's why they have larger flywheels. And hence, diesel engines typically have greater amount of torque as compared to similar sized petrol engines.

  • Flywheel or Inertia wheel used in a machine acts as a temporary reservoir of energy which stores energy when the energy supply is more than required for an operation and releases the stored energy when the supply power does not adequate with the needs. In case of the IC engines, the torque on the crankshaft fluctuates during one completed cycle of operation that causes a change in the angular velocity of the shaft. In order to obtain a uniform torque, an inertia mass is provided at the end of the shaft, known as the flywheel

  • The flywheel is a part of the engine that transfers the torque from the crankshaft to the gearbox. It also cushions engine vibrations and stalilizes the slow-running oscillations.

  • A flywheel is a mechanical device specifically designed to efficiently store rotational energy. Flywheels resist changes in rotational speed by their moment of inertia.

  • a flywheel's stored energy is by increasing or decreasing its rotational speed applying a torque aligned with its axis of symmetry. A flywheel is used to smooth fast angular velocity fluctuations of the crankshaft in a reciprocating engine.

  • theoretically it stores energy but in realtime it actually makes the engine piston reciprocate without stopping it.

  • A flywheel is a mechanical device specifically designed to efficiently store rotational energy. Flywheels resist changes in rotational speed by their moment of inertia. ... For example, flywheels are used in reciprocating engines because the active torque from the individual pistons is intermittent. Energy storage systems.

  • In four stroke engine,the larege amount of energy is released  during power stroke that energy is stored in flywheel.so we can sa that flywheel is used to store energy in engine.

  • to generate power when the engine is not run at full power
