Negative anthropogenic impact on the environment can lead to global changes in the natural cycle of substances in the biosphere and the climate change in general. Assessment of the mobile sources emission is an important component of the diagnosis of the urbanized landscapes ecosystem state. The effective power of the car engine is accepted as the characteristic unambiguously reflecting the movement of the vehicle. The algorithm of determination of pollutants emission masses is stated in the article and unique calculation of relative effective power of the engine is presented. The current value of the engine effective power taking into account transformation of variable parameters to the coded sizes depending on kinematic and dynamic factors is calculated from the equation of the car movement at the change of kinetic energy of the “engine - transport vehicle” system in the form of Lagrange. Such dynamic characteristics as coefficient of the rotating masses and coefficient of mechanical efficiency of transmission are presented by functions of the engine relative effective power. Results of the research considerably simplify calculation of pollutants emission masses by traffic flow into the atmosphere and can be used for assessment of negative anthropogenic impact on the ecosystem.
