Two-stroke engine - Wikipedia, the free encyclopedia
A two-stroke engine is a combustion engine that completes the thermodynamic cycle in two movements of the piston compared to twice that number for a four-stroke engine. This increased efficiency is ...

Four-stroke engine - Wikipedia, the free encyclopedia
Today, internal combustion engines in cars, trucks, motorcycles, aircraft, construction machinery and many others, most commonly use a four-stroke cycle . The four strokes refer to intake, compressi...
en.wikipedia.org/wiki/Four-stroke_engine
This type of internal combustion engine is called a four-stroke engine because there are four movements, ... It relies on the slightly lower pressure within in the cylinder during the intake stroke to overcome the strength of the spring holding the valve shut. Modern internal combustion engines do not work this way,
