2-stroke engine

A two-stroke engine is a type of internal combustion engine that completes a power cycle with two strokes of the piston during only one crankshaft revolution. This is in contrast to a four-stroke engine that requires four strokes of the piston to complete a power cycle during two crankshaft revolutions.

Piston – The piston transfers the expanding force of gases to the mechanical rotation of the crankshaft through a connecting rod.

Crankshaft – It converts the reciprocating motion to rotational motion.

Connecting Rod – It transfers motion from a piston to the crankshaft and acts as a lever arm.

Flywheel – It is a mechanical device that is used to store energy.

Spark Plug – It delivers electric current to the combustion chamber and in turn ignites the air-fuel mixture leading to abrupt expansion of gases.

Counter Weight – Counterweight on the crankshaft is used to reduce the vibrations due to imbalances in the rotating assembly.

Inlet and Outlet Ports – These ports allow fresh air with fuel to enter and exit from the cylinder.
