What is a two-stroke engine? And how does it work?

A two-stroke engine refers to the number of strokes the piston needs to complete in one cycle or one rotation of the crankshaft. A stroke is one up or down movement of the piston inside the cylinder. Thus, in a two-stroke cylinder, the piston moves up and down once in one cycle. More specifically, the cycle is comprised of two strokes: the "compression stroke" and the "combustion stroke" (Brain), also known as the power stroke.
