Quizplus · Accepted Answer

In a V8 engine, the crankshaft completes two revolutions (720 degrees) to complete a four-stroke cycle for all eight cylinders, resulting in a power stroke every 90 degrees (720/8). In an inline six-cylinder engine, the same two revolutions (720 degrees) are divided by six cylinders, leading to a power stroke every 120 degrees (720/6). Therefore, both technicians are correct.
