Basic Concepts of Engine Crankshafts

An engine crankshaft is a mechanical part that plays a fundamental role in the internal combustion engine. Its primary function is to convert the reciprocating motion of the pistons into rotational motion. This conversion is achieved through a series of crankpins and connecting rods, which are strategically positioned along the crankshaft. As the pistons move up and down within the cylinders, the connecting rods transfer this linear motion to the crankpins, causing the crankshaft to rotate. This rotational motion is then transmitted to the transmission system, ultimately driving the vehicle ¹.
