USAF Electrical Power Production (AFSC 3E0X2) On-Site Power Module 2 Practice Test

How many complete revolutions of the crankshaft are required for a two-stroke engine?

Two Four One Three

Correct Answer:

One

Explanation:

In a two-stroke engine, a complete operating cycle happens in one turn of the crankshaft. The design combines intake, compression, combustion (power), and exhaust within a single rotation, with the piston moving through its two strokes (up and down) during that one 360-degree turn. Because of this arrangement, unlike a four-stroke engine—which requires two crankshaft revolutions to complete a full cycle—the power cycle is finished after just one revolution.
