Why lighter flywheel is used in 2 stroke engine?

When the power stroke is over, its weight gives it the required inertia to continue to rotate. A two-stroke will typically have a lighter flywheel for the exact same reason, and every other stroke is a power stroke, so less flywheel weight is needed.

What will a heavier flywheel do?

The heavy flywheel helps RPM recovery, allows the engine not to lug during the gear transmission. The light flywheels decrease the inertia, so it gives a quick response to acceleration and deceleration.

What does a lighter flywheel do?

Since flywheels are solid, unsprung components of a vehicle’s driveline, a lightweight flywheel will decrease parasitic loss at a constant rate, improving a vehicle’s horsepower and torque output (measured after the flywheel) throughout it’s entire rev range.

How much difference does a lightened flywheel make?

“We average anywhere from 40 percent to 60 percent lighter than OEM,” Jenkins said. “It does vary per application, depending on whether you’re coming from an OEM single-mass or an OEM dual-mass flywheel.” With a lightweight flywheel, right away you will notice the engine revs more quickly.

Which of the following is true about two stroke engine when compared with a four stroke engine?

Difference Between 2 Stroke and 4 Stroke Engine

2 Stroke	4 Stroke
Uses port for inlet and outlet of fuel.	Uses valve for inlet and outlet.

Which engine has bigger flywheel 2 stroke or 4 stroke?

Flywheel size for a single cylinder engine is bigger for a 4-stroke engine than that of a 2-stroke engine.

Which is essential fly wheel or governor?

Difference between Flywheel and Governor

Flywheel	Governor
Flywheel reduces the fluctuation of speed during the thermodynamic cycles, but it does not maintain a constant speed.	Governor is a device to control the speed variation caused by the varying load.

Why spring is used in Hartnell governor?

Construction of Hartnell Governers – It is a Spring-loaded Governor. It has two bell crank levers carrying the fly ball at one end and roller attached to the other end, the function of spring is to provide the counterforce which acts against centrifugal force. The spring and shaft are enclosed inside a casing.

What is the function of the flywheel in a two-stroke engine?

The flywheel needs to provide energy to perform remaining three strokes. In a two-stroke engine, there is a power stroke in every revolution of the crank (every 360° of crank rotation) the flywheel of this engine need to provide energy for remaining one stroke.

Why is a 2 stroke engine lighter than a 4 stroke engine?

The flywheels in a 2 stroke engine is lighter than the 4 stroke engine as there is one power stroke in each revolution of the crankshaft hence providing more uniform turning movement. The uniform turning movement allows for a less weighing or lighter flywheel hence a lighter engine.

Is it good to have a light flywheel in a four-stroke?

It is not good in normal condition because light flywheels increase the tendency of the engine to die during the gear shifts. In a four-stroke engine, there is one power stroke per two revolutions of the crankshaft (720° of crank rotation). The flywheel needs to provide energy to perform remaining three strokes.

What are the advantages of a light flywheel?

The heavy flywheel helps RPM recovery, allows the engine not to lug during the gear transmission. The light flywheels decrease the inertia, so it gives a quick response to acceleration and deceleration. For this reason, light flywheels are used in the sports car.
