“…In addition, Harrison et al [37] confirmed in their analysis of the non-exhaust emissions, from abrasion of the brakes and tyres and wear of the road surface, as well as from resuspension of road dusts, that the emitted particles have to be in both the course (PM 2.5-10 ) and fine (PM 2.5 ) fractions, with a larger proportion in the former. Our results agree with those obtained in the open literature [5,35,[37][38][39][46][47][48]53,[74][75]). Our clustering could be essential to assess particle impacts on air quality and human health and, in addition, could be used in effective control measures.…”

Non-exhaust road transport emissions, particularly tyre-pavement abrasion, contribute to poor air quality. This original work is on particle emissions caused by tyre-pavement abrasion in real driving conditions in urban, suburban and motorway areas. The collected data were analyzed according to the size, the number and chemical identification. Multivariate analysis provided clusters of size and chemical elements. Results showed the predominant particles (diameter φ < 1 µm and φ ε]1-2 µm]) for urban and suburban experiments, and ]1-3 µm] on motorways. A confirmed shift phenomenon at the close-to-the-source showed particles of large sizes [5-10 µm]. The obtained clusters were: 1. Aluminosilicate, iron compounds, silicate free of aluminum (70%). 2. Ferrosilicon, silica, compounds of calcium, manganese, iron oxide, compounds of aluminum, sulfur, copper and zinc (29%). 3. A mix of various traces (1%). This paper will contribute to the development of new green technologies dedicated to improving sustainable road transport.

“…ktonnes based on measurements done in 2017/18, of which 8.1 ktonnes were from resuspension (Zhang et al, 2020). Although it is not clear whether this value only applied to light duty traffic, the value seems low when one considers the tyre and brake wear and road abrasion emissions alone in the UK were 8.7 ktonnes in 2019 (NAEI, 2020), emissions from resuspension on paved roads were 209 ktonnes in the U.S. in 2017 (USEPA, 2017) as well as the fact this would be small relative to estimates of total road transport emissions of PM10 in China ranging from 40 -400 ktonnes in 2008, depending on inventory source (Saikawa et al, 2017).…”

“…It points to emission values, such as air pollutants [45], that are produced by a vehicle in the event of various failures. According to some studies [46][47][48], the way in which these values are measured is important. Studies point to the fact that emissions can also be affected by the method of measurement.…”

The preparation of the fuel mixture of a conventional internal combustion engine is currently controlled exclusively electronically. In order for the electrical management of an internal combustion engine to function properly, it is necessary that all its electronic components work flawlessly and fulfill their role. Failure of these electronic components can cause incorrect fuel mixture preparation and also affect driving safety. Due to the effect of individual failures, it has a negative impact on road safety and also negatively affects other participants. The task of the research is to investigate the effect of the failure of electronic engine components on the selected operating characteristics of a vehicle. The purpose of this article is to specify the extent to which a failure of an electronic engine component may affect the operation of a road vehicle. Eight failures of electronic systems (sensors and actuators) were simulated on a specific vehicle, with a petrol internal combustion engine. Measurements were performed in laboratory conditions, the purpose of which was to quantify the change in the operating characteristics of the vehicle between the faulty and fault-free state. The vehicle performance parameters and the production of selected exhaust emission components were determined for selected vehicle operating characteristics. The results show that in the normal operation of vehicles, there are situations where a failure in the electronic system of the engine has a significant impact on its operating characteristics and, at the same time, some of these failures are not identifiable by the vehicle operator. The findings of the publication can be used in the drafting of legislation, in the field of production and operation of road vehicles, and also in the mathematical modeling of the production of gaseous emissions by road transport.
