The crankshaft is a fundamental mechanical component of a combustion engine and a key part of the engine rotating assembly. It is a rotating shaft with a distinctive crank throw configuration, where the throws are offset from the crankshaft’s axis: this enables the conversion of the pistons’ reciprocating motion into torque. The engine crankshaft is housed within the engine block and driven by the connecting rods and pistons, forming part of the crankshaft assembly and overall crankshaft system. Supported by main bearings, it rotates smoothly and reliably within the crankcase, while components such as the crankshaft pulley or gear and camshaft position sensor help manage timing and engine operation. Its design includes precisely balanced counterweights to reduce vibration, ensuring that the power generated by combustion is efficiently transferred to the transmission and auxiliary systems.
