There is a precedent for installing large flywheels on generators. In the 1950s, the electric-electric power generation-electric system of large steel ingot blooming mills was used. In order to reduce the cost, the capacity of the original power motor was smaller, while the capacity of the generator was larger. Large, in order to overcome sudden large loads, a large coaxial flywheel is installed on the electric-generator set.
Its characteristics are: the capacity of the prime mover is small, while the capacity of the generator is large. A large flywheel is used to store kinetic energy. Since the rolling mill rolls steel ingots, the rolling process takes a short time and the load is large. Large, it compensates for the mutation load.
I think this method is of little significance when used on generators in power plants. The motive power of the power plant is matched with the generator, and the load is basically stable, and it will not cope with sudden large loads. , Besides, the kinetic energy stored in the large flywheel is limited, and it can only compensate for short-term overload, but it cannot do anything for long-term large loads.
Is there a gasoline generator with a flywheel?
The flywheel is a cast iron inertia disk with a large mass. It stores energy, supplies the demand for non-power strokes, and drives the entire crankshaft. The connecting rod structure crosses the top and bottom dead centers to ensure the uniformity of the inertia rotation of the engine crankshaft and the uniformity of the output torque. With the help of the inertial force of the rotation of the flywheel itself, it helps overcome the compression resistance in the cylinder during starting and maintain short-term overload conditions. The engine continues to run.
1. Function: Store part of the function input to the crankshaft during the power stroke to overcome resistance in other strokes and drive the crank connecting rod mechanism to cross the upper and lower dead centers to ensure that the crankshaft The rotational angular speed and output torque are as uniform as possible, making it possible for the engine to overcome short-term overload while transmitting the engine's power to the clutch.
2. Common damage to flywheels: flywheel tooth wear, flywheel tooth breakage, flywheel surface grooves, burn scars, and cracks.
3. Inspection of the flywheel ring gear
If any individual teeth of the flywheel ring gear are damaged or one side of the ring gear is worn, you can re-chamfer the other end of the gear teeth and replace the ring gear. Use with turned sides. If the tooth length exceeds 30% or more than four teeth are continuously damaged, they should be replaced.
4. Replacement of the flywheel ring gear: The interference between the new ring gear and the outer circle of the flywheel is generally 0.3-0.6 mm. The ring gear should be heated to 350 degrees during installation. , press until hot.

The working principle of a gasoline engine is that after fuel is injected, it is ignited by a spark plug. Instantaneous combustion produces a large amount of gas, which forces the piston to run and generates power.
The flywheel is a part of the diesel engine. The working principle of the diesel engine is that the piston repeatedly presses the fuel injected into the combustion chamber. The high pressure causes combustion, and the instantaneous combustion produces a large amount of gas to force the piston to run. The flywheel is a runner with relatively large mass, which provides a certain impulse to the piston to continue the operation.
So I think the gasoline engine generator does not have a flywheel. Its working principle is similar to that of a car, except that the work is used for a different purpose.
