Detailed explanation-1: -In two-stroke engine thermodynamics cycle is completed in two strokes of the piston or in one revolution of the crankshaft. Thus there is one power stroke for every revolution of the crankshaft.
Detailed explanation-2: -Internal combustion engines (with rare exceptions) operate on either a 2-stroke or 4-stroke cycle. In both types, each full rotation of the crankshaft produces two strokes of the piston, one moving inwards towards the head of the cylinder, followed by a second which withdraws the piston back to its initial position.
Detailed explanation-3: -The two strokes occur during each revolution of the crankshaft. Therefore, it takes only one revolution of the shaft to complete a two-stroke cycle.
Detailed explanation-4: -As the name implies, the two stroke engine only requires two piston movements (one cycle) in order to generate power. The engine is able do produce power after one cycle because the exhaust and intake of the gas occurs simultaneously, as seen in Figure 1.
