crankshaft is a mechanical component in an engine that converts the reciprocating motion of the pistons into rotational motion. It is typically made of steel and consists of a series of offset crankpins connected by crank arms. As the pistons move up and down in their cylinders, they push on the connecting rods, which in turn rotate the crankshaft. This rotational motion is then transferred to the transmission and ultimately to the wheels, propelling the vehicle forward. The crankshaft also serves to balance the forces generated by the pistons, reducing vibrations and ensuring smooth operation of the engine.
