    Opis:
    The inventory results of pollutant emission from motor vehicles in Poland comparing to the emission of pollutants in the European Union have been presented in the paper. The analysis is based on the official results of the pollution inventory reported to the European Union. Emission of the following substances was considered for the years 1990-2016 for Poland and the European Union from all civilization and road transport activities: carbon monoxide, non-methan volatile organic compounds, nitrogen oxides and particulate matter consisting of fractions: total suspended particles, PM10 and PM2.5. It was observed that the share of pollutant emission from road transport in Poland is smaller than for the entire European Union. This is especially evident in the case of particulate matter and nitrogen oxides. As a result of the analysis of the emission inventory in the European Union, it was confirmed that the share of motorization in the emission of pollutants harmful to human health is significantly smaller in Poland than in the entire European Union. Therefore, conducting a detailed analysis of specific distance emission of pollutants from a statistical vehicle as well as extending research on greenhouse gas emission from motor vehicles is recommended.

    Opis:
    This article presents results of the inventory of pollutant emission from motor vehicles in Poland. To determine emission from motor vehicles in Poland COPERT 5 software was used for the first time. In addition, a comparison of the national emission from motor vehicles in 2016 and in 2015 was included. Pollutants harmful to health were considered primarily: carbon monoxide, organic compounds, nitrogen oxides and particulate matter. Emission of substances contributing to the intensification of the greenhouse effect were also examined: carbon dioxide, ammonia and nitrous oxide. It was found that the relative increase in volume of emission of carbon monoxide and non-methane volatile organic compounds is less than 10%, and nitrogen oxides and particulate matter less than 15%. The relative increase in carbon dioxide emission is approximately 14%, which corresponds to a relative increase in fuel consumption. The relative increase of volume of heavy metal emission is similar. The assessment of the energy emission factor (emission of pollution related to energy equal to used fuel) proves that - amongst pollutants harmful to health - for carbon monoxide and non-methane volatile organic compounds there is a relative reduction by approximately 5% in 2016, and for nitrogen oxides and particulate matter - increase by approximately (3-4)%.

    Opis:
    The work analyses the national annual emission of pollutants from passenger cars in Poland, in the years 2000–2015, including the classification of combustion engines relative to the ignition system. The study was carried out in accordance with the methodology used in the COPERT 4 software. The vehicle traffic model was analysed under the following conditions: urban, rural and on motorways and expressways. The national annual pollutant emission was found to change substantially alongside the changes in vehicle properties over the period analysed; the effect varied due to the performance of respective substances. The relative annual national emission of the various pollutants compared to the situation in 2000 were determined. There was a clear declining trend, from 2008 onwards, in the relative annual emission of pollutants from a representative passenger car; this was valid for all substances.

    Opis:
    National annual emission from motor vehicles were estimated with the use, for the first time in Poland, of the COPERT software programme developed in support of official reporting under the EU cooperation framework. The quantification of vehicular emission covered the period 2000–2015. The results were analysed for the following cumulated vehicle categories: passenger cars, light commercial vehicles, heavy duty vehicles, urban buses, coaches, motorcycles and mopeds. The national annual emission from motor vehicles in Poland was found to be markedly declining. The relative national annual emission of individual pollutants was balanced against the situation in the year 2000. Starting from 2006, a distinct decreasing trend was observed for the relative national annual emission of pollutants from a representative motor vehicle; this was valid for all the substances except for nitrous oxide alone.

    The paper presents the results of the study on the sensitivity of the national annual emission of pollutants from passenger cars to their average velocity under the following traffic conditions: urban, rural, and on motorways and expressways. The study was carried out in accordance with the methodology used in the COPERT 4 software. The effect of traffic speed within cumulated categories of passenger cars on the national emission of pollutants was analyzed. The national annual pollutant emission of pollutants was found to be substantially affected by the average car velocity, this effect being largely differentiated due to the character of road traffic. The type of the dependence of the national annual pollutant emission on the average velocity is similar for all substances, especially under traffic conditions in rural areas as well as on highways and expressways. A distinct minimum of the national pollutant emission was found at a velocity of about 70 km/h under rural conditions.

    The paper presents the results of the study on the sensitivity of the national annual pollutant emission from passenger cars to traffic patterns. The study was carried out in accordance with the methodology applied in the COPERT 4 software. The traffic pattern was modelled as the share of road lengths under various traffic conditions: urban, rural and on motorways and expressways, in the total length of trips covered by vehicles. A relatively small and less varied sensitivity of the national annual pollutant emission from passenger cars to the traffic pattern was found due to the substance emitted. This was considered to be a valuable proposal for the selection of parameters for the total emission model of vehicular pollutants, in view of the difficulty of estimating the share of road lengths under model traffic conditions.

    Opis:
    Within the Institute of Environmental Protection - National Research Institute the Central Emission Database is being established. The Database will cover the most important emission sectors from anthropogenic activities, including usage of motor vehicles. The intensity of emissions of individual pollutants is the input data to air pollution dispersion models. Based on calculations performed by the air pollution dispersion models concentration of pollutants dispersed in atmospheric air (pollution immission) is provided. The annual average immision for a selected place in Poland is a measure of the threat to environment. In order to determine the intensity of pollutant emissions from motor vehicles it is necessary to recognize the intensity of vehicle motion and the volume of emission of pollutants depending on the type of vehicle motion. The task presented in this article is to determine the characteristics of pollutant emissions from motor vehicles depending on the type of their motion. The mean value of vehicle speeds was used to characterize the type of vehicle motion. The emission of pollutants from vehicles is therefore characterized by the dependence of road emissions of pollutants on the average speed of vehicles. The characteristics were determined for cumulated categories of motor vehicles: passenger cars, light commercial vehicles as well as heavy duty trucks and buses. The results of the inventory of pollutant emissions from motor vehicles in Poland in 2016 were used to determine the characteristics of pollutant emissions.

    Opis:
    The paper describes the method of determination of exhaust emission characteristics from a vehicle engine based on the results obtained in a driving test simulated on an engine dynamometer. These characteristics are the relations between the specific distance emissions and the zero-dimensional characteristics of the process of vehicle velocity: the average velocity value and the average value of the absolute value of the product of vehicle velocity and acceleration. The exhaust emission characteristics are used to simulate the emissions from vehicles operating in different types of traffic conditions. The engine operating states in the engine dynamometer tests were determined by the operating conditions of the vehicle during the test. The authors applied the Monte Carlo method in order to determine the characteristics of different values of the zero-dimensional characteristics of the vehicle velocity process. This enabled the determination of the characteristics based on the test results from a single realization of the process of vehicle velocity. Additionally, the developed method allowed a replacement of the empirical research on the chassis dynamometer with the one performed on the engine dynamometer. The obtained exhaust emission characteristics are in line with the characteristics obtained on the chassis dynamometer in multiple tests.

    Opis:
    At the beginning of the twenty-first century, one of the major challenges of humanity was to reduce the negative effects of civilization development. Besides the engines used in road vehicles there is a large group of engines for non-road applications. This group includes motor propelled vehicles not used on the road NRMM (Non-Road Mobile Machinery). Engines of these vehicles, among all of the non-road applications, are characterized by very specific working conditions that do not allow for them to be qualified for propulsion engines. The main problem with these vehicles is the particulate matter and nitrogen oxides emission. Rail vehicles operating conditions these requirements take by the similar way, as having a wide range of rolling stock markedly alters the environmental impact of these vehicles. Thus it becomes necessary to consider the issue of the method of evaluation of engine emissions in rail vehicles in terms of their actual operating conditions. Thus, efforts to assess the actual level of emissivity for rail vehicles and attempts to improve it are necessary and justified.
