What Does The Crankshaft Do?

Crankshafts are also known simply as 'cranks'. It is an arrangement that converts the linear energy into rotational one. In this arrangement, a shaft is attached to pistons with cylinders. They are four in number and the pistons move back and forth alternately. This movement is known as the four-stroke cycle. The shaft is connected to a heavy wheel or disc often called flywheel. This disc stores the kinetic energy and reduces the pulsations that may surface due to the straight movements of the pistol. Often a vibration-damper is used that decreases the torsion-vibrations. These vibrations are caused by the cylinders applied in the crankshaft. As the pistons are set in motion, the shaft starts rotating. Thus, it produces rotational energy.

Al-Jahari invented the crankshaft. The size of this engine is increased by applying many pistons and cylinders. Crankshafts can be made from iron. Crankshafts are manufactured on a large scale by Thyssenkrupp and Bharat Forge Ltd.

Crankshaft is defined as shaft which transforms linear motion into rotary motion of the piston

The crankshaft is the heart of the engine. It is the shaft that goes through the bottom of the engine block from front to back that the piston connecting rods are connected to that causes the pitons to go up and down.
