dc.description.abstract | This master thesis deals with the evaluation of particle emissions from four different commercial brake pads for a typical automobile with regards to various braking conditions. A full scale inertia brake dynamometer was used to test the brake pads using portions of standardized test procedures ISO 26867 and SAE J2522 and the newly developed brake WLTC cycle for brake wear particle testing. The particle concentrations were measured online with EEPS and ELPI particle sizers sampling from an outlet duct of the dynamometer enclosure. Particle production per brake event was calculated and the effects of initial and final brake disc temperature and average dissipated power were evaluated. Both the braking intensity and the energy dissipated per brake event had considerable effect on particle production. The particle emissions during WLTC cycle representing real driving were far lower than for more severe, albeit still reasonably realistic, brake events used in standardized procedures. | cze |
