Opis:: This article aims to examine the emission of pollutants utilising transport in different points of the city in question at two different intervals, then show whether the means of transport negatively affects the city through pollution. The study of air pollutant emissions from transport sources is a key aspect towards solving problems related to environmental pollution. A study on the measurements of selected PM10 and PM2.5 pollutants to be able to determine the quality of air from transport sources in Pila at different times of the year and with appropriate assumptions regarding the appropriate distance by the road is included in this article. This study analysed data on air pollutants and compared it with the results of the Chief Inspectorate for Environmental Protection. This made it possible to propose solutions for the development of the air condition in Pila.

Opis:: One of the main objectives of the European transport policy is to increase the share of alternative modes of transport – revitalization of rail transport, promotion of water transport and development of intermodal transport, which will help to reduce the dominance of road transport. The adverse impact of transport can be felt both in the natural environment and in society, where the dynamic development of this sector has enabled significant civilization development, with the effects varying depending on the level of economic development, the degree of advancement and use of the various transport sectors, geographical location (including climate), and also the sensitivity of the elements of the environment. Considering contemporary transport hazards, it is important to prevent them from occurring, and when that is not possible – limiting their impact on the environment and reducing the scale and extent of negative impacts. The impact of rail transport on the environment and safety is much lower compared to road transport. The impact of rail transport on the environment mainly comes from the emission of noise and vibration, pollution (from diesel locomotives) and land occupation. The article presents information on the current legal conditions regarding the emission of pollutants from rail vehicles. Information with reference to research tests and emission limit values was included. The subject of tests in real traffic conditions was also mentioned as the direction of changes in vehicle homologation tests.

Opis:: The Polish Energy Sector is one of the most difficult lines of business because among other things, of the existing legal provisions, and standards relating to pollutant emissions. In the coming years, in the Polish Energy Sector breakthrough changes related to develop the energy facilities and with respect to the environmental protection will have to be introduced. During the generation of electricity harmful residues are produced, which are counteracted by equipment designed for flue gas cleaning. The Energy Sector should be concentrating on searching for the implementation of innovations to achieve emission standards.

Tytuł:: Analysis of measurement errors of cvs method used for tests of pollutant emissions from light-duty vehicles

Opis:: The test procedure for the pollutant emissions from light-duty vehicles is currently under verification carried out at the international level. For this purpose, GRPE (Groupe des rapporteurs sur la pollution et energie) – the body developing UNECE regulations proposals - has set up a task group WLTP (Worldwide harmonized Light vehicles Test Procedure) which is supposed to prepare a new GTR (Global Technical Regulation) relating to this procedure. The development of light-duty vehicles, leading to the reduction of pollutants emissions, caused the increase of the requirements for their test procedure. A large number of factors associated, inter alia, with the test equipment affects its accuracy, repeatability and reproducibility. In the ongoing analysis attention is paid even to factors, which affect test results in a relatively small way, and which have been overlooked yet. One of the problems to which attention is paid is the impact of pollutant concentration in the dilution air in the CVS (constant volume sampler) system on test results. The CVS principle is accepted as the standard method to determine light-duty vehicle exhaust emissions on chassis dynamometer test cells worldwide. It was introduced in the early 1970s. One of its drawbacks is that it introduces an error resulting from the fact that the contractual DF dilution factor, rather than the actual dilution ratio DR, is used for the correction of concentration measurement results. The article discusses this error for different type of engines used in light-duty vehicles and different pollutants subject to measurements.

Tytuł:: The impact of engine cooling fan configuration on the emission of pollutants by vehicle exhaust systems in chassis dynamometer tests

Opis:: Reduction of pollutant emission by exhaust systems due to stricter limits has drastically increased the impact of previously ignored factors on the results of emission tests. One such factor is the cooling of the engine by the chassis dynamometer's external fan. Improper cooling can increase the temperature of the engine and the catalytic converter. Preliminary studies conducted by the Motor Transport Institute have confirmed that the configuration of the cooling fan influences exhaust system emissions. This article discusses the results of tests aimed at identifying the cause of changes in emission levels. To achieve this aim, emission levels were measured for various configurations of the chassis dynamometer (including both the fan speed and the distance from the front of the vehicle). During the tests, measurements were taken of temporary pollutant levels in the CVS and of the temperature of exhaust before and after the catalytic converter. The results confirmed the findings of preliminary tests. Increased exhaust emission levels were noted, though not, as anticipated, during the urban driving cycle, but rather during the final phase of the extra-urban driving cycle. Measurements were taken using a single-roller chassis dynamometer equipped with a cooling fan with a regulated fan speed specified by a second-degree curve.
