“…The use of comfort systems almost triples their content, and the use of the sport mode increases it even more. It should be emphasized, however, that the obtained results are much lower than the approval limits and allow for conclusions about the environmental performance of the engine, which was not always found in other studies by the authors [2,3]. Another analyzed index was the number of particles per kilometre (Fig.…”

The use of comfort systems, the number of which in vehicles is constantly increasing, has a direct impact on fuel consumption and engine load. As part of the article, the vehicle's drive in real operating conditions was analyzed in terms of the emission of toxic compounds. The tests were carried out without and with the systems turned on, using the PEMS apparatus, where road emissions of carbon dioxide, carbon monoxide, hydrocarbons, nitrogen oxides and solid particles were measured in terms of mass, number and size distribution of diameters. The track was driven four times with different setting of the powertrain of examined car.

The article offers a comprehensive examination of vehicle emissions, with a specific focus on the European Union’s automotive industry. Its main goal is to provide an in-depth analysis of the factors influencing the emission of microcontaminants from light-duty vehicles and the challenges associated with their removal via exhaust aftertreatment systems. It presents statistical insights into the automotive sector and explores the relationships between vehicle categories, fuel types, and the emission of regulated and nonregulated pollutants, as well as relevant legal regulations such as the European Emission Standard. The article delves into the characteristics of vehicle exhaust, compares exhaust-gas aftertreatment systems, and introduces factors affecting emissions from gasoline engines, including downsizing, fuel composition, and engine operating parameters. It also considers the impact of driving style, start–stop systems, and related factors. Concluding, the article offers an overview of vehicle-testing procedures, including emission tests on dynamometer chassis and real driving emissions. With the growing global vehicle population and international environmental regulations, a focus on solid particles containing microcontaminants is paramount, as they pose significant risks to health and the environment. In summary, this article provides valuable insights into vehicle emissions, significantly contributing to our understanding of this crucial environmental issue.

Hydrogen is expected to be one of the most important fuels meeting stringent emission standards shortly. Using hydrogen as a fuel in an internal combustion engine (ICE) is an alternative application to replace hydrocarbon fuels that, when burned, produce harmful gases such as carbon monoxide and hydrocarbons, particulate matter, and greenhouse gases. This work provides an overview of the latest research results and future challenges and opportunities related to the use of hydrogen to power ICEs. The article presents the work of various research centres describing the technical use of hydrogen as a fuel in motor vehicles with combustion engines. Specific chemical and physical properties of hydrogen used in combustion engines were presented. The article presents modern research on a hydrogen-powered ICE. First, the basics of hydrogen engines are described, examining the engine-specific properties of hydrogen, followed by a review of the existing literature. Attention was paid to the fundamental importance of optimising the air composition from the point of view of combustion quality, NOx emissions, engine efficiency, and performance. Another issue under consideration is cleaning exhaust gases to meet future emissions regulations for hydrogen-fuelled combustion engines.
