Explain me how Will You Differentiate Between Two Stroke Engine And Four Stroke Engine?

Answer:

In case of two stroke engine, rotation of crank shaft will be power stroke for every two rotations. During compression stroke, fuel will flow towards the crank case(suction) and during power stroke, exhaust will emit the burnt fuel through the transfer ports.

While in case of four stroke engine, rotation of crank shaft will be power stroke for every four rotation. Moreover, suction compression power and exhaust strokes are separate as there will be inlet and exhaust valves.
