Final answer:
In a 2-stroke engine, the crankshaft completes 360 degrees of rotation between each ignition event, as ignition occurs once per revolution of the crankshaft.
Step-by-step explanation:
The crankshaft of a 2-stroke engine rotates 360 degrees between each ignition event. In a 2-stroke engine, each revolution of the crankshaft results in one power stroke, meaning ignition occurs once every crankshaft revolution. This contrasts with a 4-stroke engine, where ignition occurs every other revolution, resulting in a 720-degree rotation between ignition events. Knowing this can help in understanding engine mechanics and in solving related problems, such as those that involve calculating engine speeds or frequencies based on ignition events.
