Abstract
We investigate the law of exhaust gases in order to control the pollution that is increasingly present in our daily lives. Pollution is a degradation of the environment by non-natural materials in several environments constituting our universe. Thus, it intervenes as well in water, in the air as in the soil. It is mostly due to human activities, especially in urban areas and industrial areas, and the massive use of automobiles based on gasoline engines. The results show that this pollution is due in part to the existence of a mass and thermal discontinuity characterized by shock waves which occur during the evaporation process precursor of the incomplete combustion in the combustion chamber of the engines [1, 2]. By analytical approach, we establish in this paper the law φ of the exhaust gases in poor and rich reaction media during combustion in the combustion chambers of gasoline engines in order to propose the ranges of an adequate proportion of elements additive to the petrol. These engines, in operation, release various gaseous pollutants such as carbon dioxide, oxides of carbon and nitrogen, unburnt hydrocarbons, which undoubtedly contribute to the nuisance and the pollution of our environment.
