Abstract: The exergy change of the surroundings of exhaust-gas emitting ports, and its probable effects on the atmosphere, are investigated and the current stable state changing point of the atmosphere is determined. The potential for doing work is described and the effects of the amount of exhaust gas on the atmosphere are studied through calculation and analysis of an exergy-change function, which is nonlinear and dynamic. This function accounts for the flow direction of the exhaust gas in the absence of a local wind. It appears that exergy can be used as a state function to describe the change, the stability and the order of a system.

Keywords: exergy analysis; exhaust gases; atmosphere; exergy change function; nonlinear; exhaust emissions; air pollution.
