Introduction and scientific problem of internship

In the lasted time there are a lot of informations that the activities of humanity has a disheartening results for the world nature. Actually, the pollution control occupy a especial place in the contemporary science. This project directed on the combating air pollution by exhaust gases. The basic task this mathematical model is a predict of the concentration pollutants in the air.

The fundamental part of the program was produced in Swiss Federal Materials and Technolgy Laboratory.

Numerous models for the simulation of chemical phenomena in three-way catalytic converters (3WCCs) have been proposed, ranging from models of the detailed mechanism of the catalytic reac-tions on the surface to purely empirical correlations for the pollutant conversion efficiency. The application of these models for transient exhaust-gas conditions, such as real-world driving cycles, usually involves a tradeoff between the chemical background of the model, on one hand, and the computational load and ease of model parametrization on the other. In this work, a simplified mathematical model to simulate pollutant conversion in three-way catalytic converters is developed, that has a low computational load and ease of parametrization as primary priorities, but without completely disregarding the chemical background. The intended application of this model is the simulation of pollutant emissions from pilot fleets of vehicles, under real-world driving cycles, starting with a hot engine.[1]

The model is validated against a large database of measured driving cycles, performed with different types of passenger cars. It is found to present an acceptable degree of correlation between simulated and experimental results, in terms of both instantaneous and cumulative pollutant emissions, the result of work program has some insignificantly mistake and it needs to revision.
