                                            Introduction Otto cycle is an ideal themodynamic cycle that describes the functioning of a typical spark ignition engine. It is the thermodynamic cycle most commonly found in automobile engines. In an ideal otto cycle four distinct processes are followed : reversible adiabatic compression, addition of heat at constant…
