Why do engines need flywheels?

The flywheel provides mass for rotational inertia to keep your car’s engine running. Otherwise, the engine will stall when you let your foot off the accelerator. It balances the engine. A flywheel is specifically weighted to the car’s crankshaft to smooth out the rough feeling caused by even a slight imbalance.

What is the function of a flywheel how does it differ from that of a governor?

Flywheel regulates the speed of the engine during one cycle only whereas the governor regulates the speed over a period of time. A flywheel has no control over the quantity of charge (working fluid) whereas a governor takes care of quantity of working fluid.

What are the practical advantages of flywheel?

The advantages of flywheel energy storage systems are high efficiency, high energy and power density, and long life. On the other hand, flywheels are more expensive and require more space than batteries and fuel cells. There are also some safety concerns about flywheels rotating at high speeds.

What is the function of a flywheel in a prime mover?

A flywheel is used to control the variations in speed during each cycle of an engine. It maintains constant speed, but the means is different from that of Governor. It stores excess of rotational energy from the power stroke and supply back during non- power strokes of the cycle.

How does a flywheel governor work?

The flyball governor is based on the idea of a feedback control loop. It works like this: Weighted balls are linked via hinged arms to the shaft of a steam engine. As the engine turns faster, the hinged flyballs fly apart. Less steam means the engine slows down and the flyballs come back together.

What is the function of the flywheel in a car engine?

In a multi-cylinder engine, the flywheel acts, in the same way, to smooth out still more the peaks and valleys of power flow from the engine. The flywheel is also used as a part of the clutch mechanism and fluid drive unit.

What are the advantages of a heavier flywheel?

Heavier flywheels allows engines to work under loads that may cause the engine to bog down; thus cars consistently pulling heavy trailers should benefit from a larger flywheel.

What are some examples of flywheels in daily life?

Some others examples of flywheels in daily life are automobile engines, sewing machine and manual sugarcane juice extractor. A flywheel is in existence since the dawn of industrial revolution.

How does a flywheel store and release energy?

The energy stored to these flywheel are proportional to their square of rotating speed. A torque is applied to the flywheel to store rotational energy and when needed; energy is released from flywheel in the form of torque applied on the mechanical load. Thus it increase its rotational speed while storing energy and loose while releasing it.
