Flywheel Function on Engine – This discussion will provide information about the function of the flywheel on the engine. Fly wheel is a rotating mechanical component used to withstand changes in engine rotation speed by utilizing rotational inertia (moment of inertia). With significant inertia properties, this fly wheel is able to store mechanical energy in a short time.
The amount of mechanical energy stored on the fly wheel, has a value comparable to the square of rotation speed. The mechanical energy is then channeled to the fly wheel with the available torque, thus increasing the rotation speed. That way, mechanical energy can be stored. Meanwhile, the fly wheel releases stored energy by performing torque to the mechanical load, reducing the speed of the spin.
For example, the fly wheel is used to maintain speed at a constant crankshaft angle inside the piston engine. The crankshaft-mounted flywheel stores energy when torque is exerted on the fly wheel by a moving piston and releases energy into the mechanical load if the piston state is not producing power.
In some types of engines, the fly wheel is functioned as a clutch seat. The clutch is used to pass engine power to the axle shaft. In addition, there are also those who make use of this fly wheel as a place where the gears of the starter motor pinion are attached. So the fly wheel will receive rotary power from the starter motor which is then passed to the crankshaft. That way, the crankshaft will spin and the machine can start life.
Flywheel Function on Engine
In general, the functions of the fly wheel are as follows:
Provide energy continuously when the energy source is disconnected. For example, fly wheel used in piston engine, because the energy source is torque from the engine, then the energy will be intermittent (not constant).
Provide energy beyond the ability level of the energy source continuously. This is done by the fly wheel by collecting energy over time. Then the energy is released quickly, with a higher level of energy source capability.
Fly wheel serves to control orientation on a mechanical system. In this case, the angular momentum of the fly wheel is accidentally transferred to the mechanical load at the time the energy is transferred from or to the fly wheel.
Fly wheel is used to make the torque produced by the fuel motor to be more stable.
Fly wheel is a component contained in diesel engines and gasoline cars. Its function here is as a spinning period and is used to store mechanical energy in the machine. With the fly wheel, the engine rotation becomes stable and balanced.
Fly wheels are usually made of high quality steel and rotate on conventional bearings. And it generally has a revolution rate limit of less than 1000 rpm. Meanwhile, some are made of carbon fiber using magnetic pads that allow it to rotate up to 60,000 rpm.
On some engines, the fly wheel is equipped with ring gear attached to the edges. Its function is as a connecting medium with pinion gears on the starter motor. While in this type of automatic transmission vehicle, usually use torgue converter instead of fly wheel.
The fly wheel is firmly mounted at the end of the crankshaft and locked with a fastening nut, so it is not easily shifted from its place. It also aims to ensure that the fly wheel and ignition timings remain in the correct position.
Such is the discussion of what are the functions of fly wheel in the engine. Hopefully useful.
