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 a "V" shape, typically with four cylinders on each side of the engine. Despite having eight cylinders, all of these cylinders are powered by a single crankshaft that converts the linear motion of the pistons into rotational motion, enabling the vehicle to move. This design is efficient for balancing power and performance in engines. Therefore, the correct answer aligns with how a V-8 engine operates, emphasizing that the crankshaft plays a crucial role in the engine's functionality.
