crankshaft

A crankshaft is a key component in an engine that converts the up-and-down motion of the pistons into rotary motion, which powers the vehicle. Inside the engine, as fuel combusts, it pushes the pistons downward. The crankshaft, connected to these pistons via connecting rods, rotates as the pistons move, transmitting power to turn the wheels. It also helps synchronize engine components and ensures smooth operation. Essentially, the crankshaft acts as the engine's main rotating axis, transforming linear piston energy into usable rotational energy that drives the vehicle forward.
