internal combustion engine type
A two-stroke engine is a type of internal combustion engine that completes a full power cycle in just two strokes of the piston, making it simpler and more compact than other engine designs. It's commonly used in smaller applications like chainsaws, lawnmowers, and some motorcycles because of its lightweight construction and high power output relative to its size.

Animation of a two-stroke engine
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes of the piston, one up and one down, in one revolution of the crankshaft in contrast to a four-stroke engine which requires four strokes of the piston in two crankshaft revolutions to complete a power cycle. During the stroke from bottom dead center to top dead center, the end of the exhaust/intake (or scavenging) is completed along with the compression of the mixture. The second stroke encompasses the combustion of the mixture, the expansion of the burnt mixture and, near bottom dead center, the beginning of the scavenging flows.
