Kaksitoimiseen is a Finnish term that translates to "two-stroke" in English, commonly referring to a type of internal combustion engine.

This is achieved by combining the intake and compression strokes into one, and the power and exhaust strokes into the other.
The fundamental difference lies in the port system. Instead of valves, two-stroke engines use ports in the
The resulting explosion drives the piston downwards, performing the power stroke. As the piston moves down,
