Two Stroke Cycle

Two Stroke Engine Figure With Parts
FIGURE 5.3. Parts of a two-stroke cycle engine.

The spark plug Ares, the piston reaches top dead center (TDC), burning occurs, and pressure builds rapidly in the cylinder. This is called the ignition and power event. As soon as the piston moves away from the head far enough to expose the exhaust port, the cycle begins again.

If you count the movements of the piston, you will find that it has traveled two strokes or one revolution of the crankshaft. Because both the exhaust and the intake processes are not as efficient as in the 4 cycle engine, the 2 cycle engine will produce less power per stroke. However, because it has a power event each crankshaft revolution, the total power produced by the engine is comparable to that of a 4 cycle engine.
