1. Description

A two-stroke engine is a kind of internal com­bustion engine which requires two strokes within
a full cycle. It involves a combustible mixture of
air and fuel being ignited by a spark plug.

The crankshaft conveys the force and also con­trols the changes in the gas mixture. The up­ward motion of the piston results in both com­pression and ignition, while the downward mo­tion results in a new mixture of gases being
injected.
