What is a flywheel and how does it work?

A flywheel is essentially a mechanical battery consisting of a mass rotating around an axis. It stores energy in the form of kinetic energy and works by accelerating a rotor to very high speeds and maintaining the energy in the system as rotational energy.

What does the crankshaft do?

The crankshaft converts reciprocative motion to rotational motion. It contains counter weights to smoothen the engine revolutions. There are two types of crankshaft, the monolithic type (Fig. 8.1), used for multi-cylinder engines, and the assembled type (Fig.

How does a flywheel help an engine run?

The mass of the flywheel applies inertia to keep the engine crankshaft turning between each of these piston firings, so the rotation speed of the crankshaft is kept constant and the engine runs smoothly.

What does a cylinder do?

A cylinder is a vital part of the engine. It’s a chamber where fuel is combusted and power is generated. The cylinder consists of a piston and two valves at the top; an inlet and exhaust valves. The piston moves up and down, and its reciprocating motion generates power that moves your vehicle.

What is a flywheel and what does it do?

An industrial flywheel. A flywheel is a mechanical device specifically designed to efficiently store rotational energy. Flywheels resist changes in rotational speed by their moment of inertia. The amount of energy stored in a flywheel is proportional to the square of its rotational speed.

What is the purpose of a flywheel in an engine?

Smoothing the power output of an energy source. For example,flywheels are used in reciprocating engines because the active torque from the individual pistons is intermittent.

What are flywheels used for?

A flywheel is a rotating mechanical device that is used to store rotational energy. Flywheels have an inertia called the moment of inertia and thus resist changes in rotational speed.

What is a flywheel in a car engine?

Every car has a flywheel. Flywheels are heavy metal disks, between 12 and 15 inches in diameter, with gear teeth cut into its circumference. They are attached to the rear of the crankshaft, between the engine and the transmission.
