How many crankshafts are there in a V-8 automobile engine?

In a V-8 automobile engine, there is one crankshaft. The design of a V-8 engine includes eight cylinders arranged in two banks of four cylinders each, forming a 'V' shape. Regardless of the number of cylinders, the engine operates with a single crankshaft that converts the linear motion of the pistons into rotational motion, which ultimately drives the vehicle. This single crankshaft methodology is common in multi-cylinder engines for efficiency and structural integrity, as it simplifies the engine's design while still effectively managing the power output from all eight cylinders.
