Who is correct regarding the revolutions of the crankshaft and camshaft in a two-cycle engine?

• A. Technician A
• B. Technician B
• C. Both Technician A and Technician B
• D. Neither Technician A nor Technician B

Answer: (B)

In a two-cycle engine, the relationship between the revolutions of the crankshaft and the camshaft is crucial to understanding their operation. In this type of engine, for every revolution of the crankshaft, the engine completes all necessary cycling for intake, compression, power, and exhaust, which happen in a single turn. Because of this design, the camshaft typically rotates at the same speed as the crankshaft or not at all, since there is no need for multiple strokes like in a four-cycle engine that would require distinct intake and exhaust strokes regulated by a camshaft. Therefore, Technician B is correct by indicating the distinct relationship between these two components in a two-cycle setup, where the camshaft's function is minimized or altered compared to a four-cycle engine.
