Driving Cycles

This paper reviews the emissions of reactive nitrogen compounds (RNCs) from modern vehicles fitted with spark ignition en-gines and three-way catalysts. Specific aspects of the pollutants involved – and their formation – are discussed. Cold start driving cycles are scenarios under which emissions of all four RNCs can be significant; the mechanisms behind emissions trends are ex-plored. Experimental data obtained from two vehicles tested over two different cold start driving cycles are presented and analysed. The use of gravimetric and molar metrics are explored. Ammonia, a species which is currently not regulated for passenger cars in any automotive market, is identified as forming the majority of the RNC emissions over the entire driving cycle. While ammonia emissions are strongly linked to aftertreatment system warmup and periods of high load, significant ammonia emissions were also measured under certain hot-running, low load conditions, and even at idle. For the majority of the duration of the test procedures employed, the RNC profile was dominated by ammonia, which accounted for between 69% and 86% of measured RNCs in the ex-haust gas. Emissions are compared to the available legislative precedents (i.e. emissions limits currently in force in various jurisdic-tions). Finally, possibilities for control of exhaust emissions of currently unregulated RNCs are briefly discussed.

Degree Of Recovery

The aim of the article is to present the environmental effects of changes in material composition in selected internal combustion engines used in passenger cars using LCA analysis. The levels of energy consumption and emissions of pollutants related to material inputs occurring at the stage of engine production have been determined. The simplified LCA model presented in the paper shows the energy consumption and total CO2 and SO2 emissions on the basis of the mass of materials from which the engine is made. The research results presented in the paper give a picture of a modern passenger car engine on the basis of wear and the degree of recovery of materials used for its construction.

Car Market

According to the title, the article compares passenger cars produced in versions with SIE engines (spark ignition engines) and CIE engines (compression ignition engines), taking into account the situation on the Polish automotive market. A group of 25 selected vehicle pairs equipped with the SIE and CIE engine versions has been presented. The measurable comparative criteria have been defined. The results of the comparison were presented in the form of graphs with a commentary. The situation on the Polish automotive market was also assessed in the context of a comparison of both types of vehicles. The final conclusions close the article.

The Impact

The article describes aspects related to the impact of toxic components of exhaust gases from motor vehicles, which are equipped with spark-ignition engines for environmental pollution and a negative impact on human health. The paper presents aspects related to the structure of passenger cars in Poland and the European Union, which are in operation and subject to mandatory control tests. The methodology of performing mandatory periodic check-ups in diagnostic stations and on the basis of the developed research results also includes a group of vehicles that does not meet the legal requirements for the measurement of exhaust emissions. The results of passenger car tests in selected European Union countries have been presented.
