Within this work, field observations of structure and intensity of motor transport streams were conducted, the information about the operating sources of atmosphere pollution from the enterprises in the city of Naberezhnye Chelny, their qualitative and quantitative structure, physical parameters were collected, processed and systematized. On the basis of the obtained data a summary calculation of emissions of the industrial enterprises and motor transport was carried out, the list of the priority polluting substances was defined, the complex index of pollution of the atmosphere was calculated, highways with the greatest transport loading were defined. On the basis of instrumental control the measurements of quality of atmospheric air near highways were carried out, actions for optimization of transport streams and decrease in negative impact were offered.

The combination of factors that determine the level of atmospheric pollution, the priority harmful component of which is dispersed particles, has a random and unique character for the urbanized territory of «InnoKam». Therefore, to study the process of atmospheric pollution of this urbanized territory, an approach was used that takes into account that the content in the air of dispersed particles of motor transport and industrial origin depends on the nature of the processes of upsurge, propagation and deposition, which are determined by the fractional composition of particles, structural and functional parameters of road traffic flows., climatic and urban features of the territory and meteorological conditions. The aim of the study is to reveal the patterns of air pollution in the urbanized territory of «InnoKam» with dispersed particles, which is relevant and necessary for the effective implementation of measures to create a favorable and comfortable urban environment, as well as the attractiveness of the innovation and production center for visiting specialists and investors. Regularities of air pollution in the urbanized territory of «InnoKam» by dispersed particles, which is formed when pollution from road traffic flows are superimposed on the polluting background of industrial enterprises, have been investigated. Motor transport streams are both independent sources of the formation of dispersed particles, and a source of upsurge and spread of dispersed particles over considerable distances beyond the boundaries of highways. To reveal the regularities and obtain the corresponding mathematical models, both instrumental methods based on measuring the content of dispersed particles DCh 10 and DCh 2.5 in the atmosphere of the investigated urbanized territory, and statistical analysis of experimental data were used. Mathematical models have been obtained that, with a high degree of reliability, describe the regularities of air pollution by dispersed particles for the urbanized territory of «InnoKam», which is the scientific value of the results obtained. The practical significance of the results obtained lies in their use for predicting and compiling air pollution maps with dispersed particles in all parts of the urbanized territory of «InnoKam» in order to develop and substantiate measures to create a favorable and comfortable urban environment. The main activities are analyzed and divided into three groups, based on the specifics of the sources of formation of dispersed particles (vehicles, traffic flows, highways). The ranking of measures for the effectiveness of reducing air pollution by dispersed particles is the object of further research.

The information on existing stationary sources of atmospheric pollution, their qualitative and quantitative characteristics, factual emissions was collected and analyzed within the framework of the present study. On-site investigations of the structure and intensity of the traffic flow on the main thoroughfares of Naberezhnye Chelny were conducted.Based on the obtained data, a summary calculation of 143 pollutantswas carried out, taking into account those, included in 28 summation groups;maps of distribution of air pollution level throughout the city were drawn and analyzed for each substance, first-ever for Naberezhnye Chelny.Based on the results of calculation of pollutants dispersion, a forecast was made for the concentrations of pollutants in the residential area of the city. The substances and summation groups, for which maximum permissible concentration is likely to be exceeded (carbonic oxide, nitrogen dioxide and the summation groups, formed by these substances) were detected. Along major automobile highways and interchanges, the zones with expected values of maximum surface concentrations of more than 1 MPC were observed for carbonic oxide.

The current level of motorization makes high demands on the reliability of vehicles, to the provision of technical and economic properties and to reduce the technogenic impact, primarily -the emissions of harmful substances into the environment. The world automobile industry is currently developing in the direction of electronic engine management system use to improve the quality of vehicle operation, fuel efficiency and environmental safety. The analysis of automotive internal combustion engine performance equipped with electronic control systems showed that at the first stages the design improvement led to functional and parametric failure increase, as well as to their qualitative change. In this regard, the need appeared to develop new methods and tools for diagnosis. Thus, the problem of new methods creation and the development of existing methods to diagnose electronic engine control systems is topical.The research was carried out using the elements of system analysis and decision theory, mathematical modeling, probability theory and mathematical statistics, the theory of expert evaluations, image recognition and experimental research.The paper demonstrated the results of the mathematical model development for the interrelation of the technical state of element parameters concerning automotive mechatronic systems with the output parameters of automobile engines, diagnostic algorithms, and the experimentally obtained parameters of diagnostic areas. The obtained results are diagnostic algorithms, diagnostic parameter values and their interpretation which allow to reduce the time spent on the troubleshooting of automotive mechatronic systems during car maintenance and repair. The developed theoretical positions, the results of experimental research and practical recommendations are intended for the use in motor transport and service enterprises during the servicing and the repair of mechatronic automotive systems.
