Model emisji zanieczyszczeń z silników pojazdów samochodowych do atmosfery

Magdalena Zimakowska-Laskowska

Abstract

It is impossible to determine the total amount of pollutants produced by internal combustion engines by direct measure. The only way of obtaining data on this emission is modelling. The total pollutants emissions from internal combustion engines depends on: the number and intensity of use of the vehicles (mileage) in each of their categories, vehicle traffic models, environmental conditions (including atmospheric conditions) and the ecological properties as the characteristics of pollutant emissions. Over long periods of time of balancing the emission of pollutants, e.g. 1 year, the atmospheric conditions can be treated as an averaged value. Similarly, other environmental conditions occurring in a larger area can be treated as averaged. The complex structure of factors that determine the emission of pollutants from internal combustion engines means that creating a formal system for obtaining comparable results is vital, especially as the amount of pollutant emission is highly sensitive to the engine operating conditions. The model of the total pollutant emissions from internal combustion engines is built on the assumption that the emission is a superposition of emissions from vehicles in the given categories and vehicle traffic models which is representative of the actual use of the vehicles. The aim of this research is to develop a model of the total emission of pollutants from internal combustion engines in the following years: 2010, 2012 and 2014 produced by the following categories of vehicles: passenger cars, light duty vehicles, urban buses, coaches, heavy duty vehicles, motorcycles, motorbikes. Vehicle traffic models in cities, outside cities, on motorways and dual carriage ways will be described in relation to the average velocity of vehicles, the evaluation of which will be based on the results of empirical research. The characteristics of pollution emissions will be designated as the dependence of road pollution emissions i.e. carbon monoxide CO, organic compounds (as hydrocarbons and their derivatives), nitrogen oxides (as nitrodioxide NO2), particulate matter PM and carbodioxide CO2 on average velocity. To determine the characteristics of pollutant emissions from internal combustion engines data of the results of empirical research from available databases for elementary categories of vehicles (e.g. INFRAS and COPERT) and vehicle structure declared in European databases in the form of number of vehicles and mileage for elementary vehicles category will be used. The characteristics of pollutant emissions from internal combustion 8 engines for elementary categories of vehicles will be verified by empirical studies conducted on a chassis dynamiter and also in traction conditions. As the pollutant emission value cannot be determined empirically, in order to verify the model balancing of the fuel consumption is used i.e. the results of the research of the model and the total fuel consumption. Simulation tests of the constructed model will include the evaluation of the impact of the ecological structure of the vehicle and its use in relation to the traffic model (traffic in cities, outside cities, on motorways, dual carriage ways, as well as representative average speed of vehicles in such traffic conditions) to emissions and fuel consumption.
