It is important to understand the term Otto Cycle because it is different than the combustion cycle that diesel engines used known as the “Diesel Cycle.” This cycle is also a four-stroke process, but the details of how each process works are different than the Otto Cycle.īelow are the four unique processes for combustion to take place in a typical gasoline engine.

Each step in the process is named with the word stroke in it intake stroke, compression stroke, power stroke, and exhaust stroke.

A German engineer named Nikolaus Otto was the first person to invent and patent a four-stroke gas engine. The four-stroke engine process is also known as the Otto Cycle.
