The Otto cycle is an idealized thermodynamic cycle proposed by Nikolaus August Otto in 1876. This cycle describes the functioning of a typical reciprocating piston engine. This thermodynamic cycle is used in automobile engines. This cycle consists of two adiabatic and two isochoric transformations. The thermal efficiency of this cycle is given by: η = 1 - r
^{(1 - γ)}, where r is the compression ratio and γ is the specific heat ratio, taken to be 1.4 for air in the present Demonstration. |
