How many degrees complete a full crank rotation?

A full crank rotation encompasses a complete circle, which is measured as 360 degrees. This means that any time the crankshaft makes one full turn, it has rotated 360 degrees.

The concept surrounding crank rotation is essential to understand in the context of an internal combustion engine, as the crankshaft is responsible for converting the linear motion of the pistons into rotational motion. Each full rotation corresponds to the cycle of the engine's four-stroke process—intake, compression, power, and exhaust—effectively completing one full cycle at 720 degrees for two full crank rotations.

Understanding this concept is critical for diagnostics, performance tuning, and general maintenance practices, as it allows technicians to evaluate timing settings and component wear accurately in relation to the engine's operational cycle.
