Vehicle related non exhaust particle emissions – Euro 7 requirements

Abstract

The article is a multi-directional review of the current knowledge in the field of particulate matter emissions from motor vehicles, but not related to the combustion process in piston combustion engines. A summary of the research results available in the literature was provided regarding the size and composition of particulate emissions from abrasive wear of working elements of brake systems and tires. The mechanisms of particulate matter formation related to the wear processes of brake pads, discs and tires were described. Reference was made to currently available research results regarding the harmful, toxicological impact on health of chemical components contained in particulate matter, in particular on diseases of the respiratory and cardiovascular systems. A critical analysis of various, previously unstandardized measurement and assessment methods for the emissions of this particulate matter category was carried out, pointing to future needs. Relating, in particular, to the requirements of the new Euro 7 standard.
