What is a 2 stroke engine?

A 2 stroke engine is similar to the common 4 stroke engine, except that it completes the same four processes in two strokes of the piston rather than four. This creates a power stroke for every revolution of the crank, instead of every second revolution. Two stroke engines provide high power for this reason, and are often used in portable, lightweight situations, such as motors and chainsaws.

When dealing with a 2 stroke engine, it’s important to use 2 stroke oil to ensure the engine will operate properly.
