2 stroke engine

grabcad

A two-stroke engine is a type of internal combustion engine that completes its power cycle in just two strokes of the piston, rather than the typical four-stroke cycle used by most engines. These engines are commonly found in small equipment like lawnmowers and chainsaws due to their simplicity and lower cost compared to four-stroke engines. However, they also have higher emissions and require a constant fuel/oil mix for lubrication.
