two stroke and four stroke difference in malayalam
two stroke and four stroke difference in malayalam
Today I am going to tell you about main difference between 2 strokes vs 4 stroke engines. We all heard about both of these engines but few of us know the basic differences between them. Before discussing on this topic first you should know about stroke. The stroke in an engine is the distance covered by the piston from top dead center to the bottom dead center. In simple words, stroke is the distance of cylinder between piston moves. If a piston moves 2 times in the cylinder, that means, engine is known as two stroke engine and if it moves 4 times in a four stroke engine. The crankshaft rotates one time between 2 strokes
It has one revolution of crankshaft within one power stroke.
It has two revolution of crankshaft between one power strokes.
2.
It can generate high torque compare to 4 strokes engine.
It generates less torque due to 2 revolution of crankshaft between one power strokes.
3.
It used port to inlet and outlet of fuel.
It used valve to inlet and outlet.
4.
2 stroke engines require lighter flywheel compare to other engines because it generates more balanced force due to one revolution for one power stroke.
It requires heavy flywheel because it generates unbalance force due to two revolutions for one power stroke.
5.
The charge is partially burn and mix with the burn gases during inlet. It is due to port mechanism.
In four stroke engine charge is fully burn and does not mix with burn charge in ideal condition.
