Engine Crankshaft 11217580483 for BMW E82 E84 E88 F02 F06 F07 N55B30A

#Operation of Crankshaft

As a key part of internal combustion engine, crankshaft mainly has the following functions:

• Rotary motion: The main function of the crankshaft is to convert the linear reciprocating motion of the piston into the rotary motion of the engine components such as the flywheel, gearbox and accessories.
• Supporting load bearing surface: The crankshaft provides a load bearing surface for the engine connecting rod.
• Balancing the engine: Counterweights on the crankshaft help balance the rotating components of the engine, reducing vibration and improving engine ride comfort and service life.
• Distributed lubrication: the oil circuit of the crankshaft distributes lubrication to each bearing surface of the engine, which can reduce friction and wear.
• High stress bearing: Crankshafts are designed to withstand the high stresses and loads generated by engine operation.
