Otto cycle: It is the decription of what happens to a mass of gas as it is subjected to change in pressure,temperature,volume,addittion of heat and removal of heat. Use of otto cycle: It describes how heat enhine turns gasoline into motion,the cycle turns chemical energy into thermal energy and then into motion. PV diagram: On the figure we show a plot of pressure versus gas volume throughout one cycle. We have broken the cycle into six numbered stages based on the mechanical operation of the engine. For the ideal four stroke engine, the intake stroke (1-2) and exhaust stroke (6-1) are done at constant pressure and do not contribute to the generation of power by the engine. A typical spark ignition Otto cycle engine could have a compression ratio of the order of 10, and exhibit exhaust temperature and pressure of 200 0 C and 200kiloPascals respectively.

  The Otto cycle is a description of what happens to a mass of gas as it is subjected to changes of pressure, temperature, volume, addition of heat, and removal of heat. The mass of gas that is subjected to those changes is called the system. The system, in this case, is defined to be the fluid (gas) within the cylinder. The Otto cycle is often plotted on a pressure- volume diagram (pV diagram) and on a temperature-entropy diagram (Ts diagram). When plotted on a pressure volume diagram, the isochoric processes follow the isochoric lines for the gas (the vertical lines), adiabatic processes move between these vertical lines and the area bounded by the complete cycle path represents the total work that can be done during one cycle.
