AUTOEXE SPORTS FLYWHEEL FOR MAZDA ROADSTER NCEC MT MNC640
The flywheel is a part that absorbs torque fluctuations that occur in the operating process of the engine and stabilizes rotation.
It is attached to the rear end of the crankshaft (or eccentric shaft in the case of RE) of the engine.
In a lightweight flywheel for tuning, weight (mass) is generally used as an index of performance.
but is the mass distribution concentrated in the center of rotation?Is it on the outer circumference?
The magnitude of the moment of inertia is the key to the characteristics of the engine.
The moment of inertia is like a coefficient that determines the ease of rotation, and if it is small, the response will improve, but there will be disadvantages such as engine stall, insufficient torque at low rotation, and increased vibration.
On the contrary, if it is large, the rotation becomes smooth, but the response deteriorates.That's why it's difficult to balance.
In mass-produced cars, it is unavoidable that the moment of inertia is large due to consideration for ease of handling and comfort, but there is room for improvement if we focus on drivers who want a sense of unity with the car.
Autoexe "Sports Flywheel" reduces the moment of inertia by 28-37% compared to mass production (in the case of a reciprocating engine).
The specifications combine agile accelerator response that synchronizes with the sensibilities of drivers who enjoy driving on the street and stress-free operability.
Chromium molybdenum steel with excellent thermal stability is used as the material.
If possible, Autoexe recommend that you install it at the same time as the clutch line, which enhances the direct feeling when operating the clutch.
About Inertia:
1. When trying to rotate with the same force, the moment of inertia and the acceleration are in inverse proportion to each other.
2. Therefore, the smaller the moment of inertia, the larger the acceleration and the higher the number of rotations.
3. On the contrary, the larger the value, the smaller the acceleration and the more difficult it is for the rotation speed to increase.
4. The relationship between the moment of inertia and the engine speed is "force to rotate (Nm) = moment of inertia (kgm)".2) × Acceleration (rad / sec2) ”.
5. In this case, the "force to rotate" is the engine torque (Nm) and the "acceleration (to be exact, angular acceleration)" is how the number of revolutions increases, that is, the momentum of rotation.
