Crank Shaft

•  The crankshaft is located inside the engine block, typically near the bottom of the engine., where it is connected to the pistons via connecting rods.
• The crankshaft rotates as the pistons move up and down, and this rotational motion is used to power the vehicle’s wheels.
• The main function of the crankshaft is to transform the piston’s linear motion into rotary motion and turn the vehicle wheels
• The crankshaft plays a crucial role in the power transmission system. The reciprocating movement of the piston is converted into rotating movement by using the connecting rod.
• The crankshaft consists of crankpins, crank webs (crank arms or cheeks), balancing weights, and main journals. The large end of the connecting rod is attached to the crankpin of the crankshaft one complete revolution of crankshaft makes two strokes of the piston.
