Two Stroke Engine, Transparent

1. Description
A two-stroke engine is a kind of internal com-
bustion 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 con-
trols the changes in the gas mixture. The up-
ward motion of the piston results in both com-
pression and ignition, while the downward mo-
tion results in a new mixture of gases being
injected.
