How Two Stroke Engines Work (How It Works - 2 Stroke)

Learn how a two stroke engine works! We look at the two stroke engine’s main components, how it works, its applications, advantages and disadvantages. The animation clearly shows the cycle of the engine as it moves though the induction, compression, power and exhaust strokes. Coloured arrows are used to show the movement of the gasses through the engine.

▶️Introduction
Two stroke engines are of a simple and robust design. They are almost always petrol/gasoline fired engines. Two stroke engines are spark ignition type engines and are used primarily for small or very large applications.

The two stroke engine has found widespread use as it is relatively cheap and has a high power to weight ration compared to other prime movers.

Components shown in this video include the crankcase, crank webs, piston, con rod, injector, cylinder liner and spark plug.

Advantages
Simple design.
Robust and reliable.
Few components.
High power to weight ratio.

Disadvantages
Not very efficient compared to other prime movers.
Noisy/loud compared to four stroke engines.
