WebThe Otto cycle is a set of processes used by spark-ignition internal combustion engines (two-stroke or four-stroke cycles). Nikolaus August Otto first designed what is known as the four-stroke engine. A stroke refers to the full travel of the piston along with the cylinder in either direction. WebOtto Cycles have four stages: expansion, cooling, compression, and combustion. Figure 1: moving up during expansion Expansion: In the Otto cycle, fuel is burned to heat …
