Abstract

Dozvoljene emisije štetnih tvari u ispušnim plinovima regulirane su Euro emisijskim razinama,
no emisije koje nastaju kao posljedica trošenja kočnica i guma još su uvijek dio aktualnih
istraživanja te se njihove granice tek trebaju jasno definirati. Kako bi se utvrdile emisije štetnih
tvari potrebno je proučiti sastav pojedinih komponenti, definirati postupak ispitivanja te
kontrolirati uvjete, u kojima se testiranje odvija, kako bi dobili što točnije rezultate. Emisije
štetnih tvari, provode se i u realnim uvjetima vožnje, ali i u laboratorijskim uvjetima. Tema
ovog rada je analizirati i proučiti samu građu kočnica i guma vozila, a potom izvjestiti o
emisijama koje nastaju prilikom njihovog trošenja. Bitno je spomenuti u kojim se veličinama
pojavljuju te štetne čestice, kakva im je raspodjela, emisijski faktor te sam utjecaj na zdravlje
živih bića. Također, bit će i usporedba između vozila s motorom s unutarnjim izgaranjem i
električnih vozila. Iako je poznato da se električna vozila smatraju vozilima bez emisija jer
nemaju ispuh, u ovom radu će se pokazati da to nije tako.
U radu su također prikazani neki ispitni postavi koji su korišteni u različitim istraživanjima za
određivanje emisija kočnica i guma, bilo u laboratorijskim uvjetima bilo u realnim uvjetima
stvarne vožnje. Na kraju rada biti prikazan prijedlog odnosno koncept ispitnog sustav za
prikupljanje i mjerenje štetnih čestica.

Abstract (english)

Allowed vehicle emissions of exhaust gases are regulated by Euro emissions, but emissions
from brake and tire wear are still under research, and their limits have yet to be clearly defined.
To determine emissions of harmful substances, it is necessary to study the composition of
individual components, define the testing procedure, and control the conditions under which
testing takes place to obtain as accurate results as possible. Emissions of harmful substances
are conducted, both, under real driving conditions and in laboratory settings. The topic of this
paper is to analyze and study the structure of vehicle brakes and tires and then report on their
emissions. It is important to mention the size at which these harmful particles appear, their
distribution, emission factors, and their impact on the health of living organisms. Additionally,
a comparison will be made between internal combustion engine vehicles and electric vehicles.
Although electric vehicles are considered emission-free because they have no exhaust
emissions, this paper will show that this is not entirely accurate. The paper also presents some
test setups that have been used in various studies to determine brake and tire emissions, either
in laboratory conditions or under real-world driving conditions. At the end of the paper, a
proposal or concept for a test system for collecting and measuring harmful particles will be
presented.
