20.500.12556/RUL-119474 Pregled standardov za maziva pri motorjih na notranje zgorevanje in njihov vpliv na okoljsko problematiko Overview of lubricants standards in combustion engine and their effect on environmental issues Vedno strožje okoljevarstvene in zakonodajne zahteve vplivajo na proizvajalce motorjev z notranjim zgorevanjem. Zaostrovanje zahtev o čistosti izpušnih plinov močno vpliva na razvoj motorjev, sistemov za prečiščevanje izpušnih plinov in posledično tudi na razvoj motornih olj. Le ta morajo ob tem vedno zadostiti zahtevam po optimalnem delovanju in kvalitetni zaščiti motornih delov, obenem pa ne smejo negativno vplivati na čistilne sisteme. Poleg omenjenih zahtev pa motorna olja neposredno vplivajo tudi na samo porabo goriva in posledično tudi na količino nevarnih izpustov. Vsi zgoraj omenjeni dejavniki zahtevajo neprestan razvoj in napredek na področju motornih olj. V diplomski nalogi sem opravil pregled različnih standardov za motorna olja avtomobilskih agregatov in kako so se le-ta spreminjala z zahtevami avtomobilskih proizvajalcev in razvojem naprednih tehnologij. Primerjal sem avtomobilske agregate različnih letnikov in prišel do zaključka, da so agregati vedno bolj obremenjeni, olja pa vedno manj viskozna. V zaključku pa sem pregledal še možnosti za varno odstranjevanje in ponovno uporabo motornih olj. Increasingly stringent environmental and regulatory requirements affect manufacturers of internal combustion engines. Stricter exhaust gas purity requirements have a significant impact on the development of engines, exhaust gas purification systems and consequently on the development of engine oils. Oils always have to meet the requirements for optimal operation and quality protection of engine parts, while not adversely affecting cleaning systems. In addition to the requirements above, motor oils also have a direct effect on fuel consumption and, consequently, on the number of emissions. All the above factors require contestant development and progress in the field of motor oils. In my dissertation, I reviewed different standards for motor oil engine oils and how they changed with the requirements of car manufacturers and the development of advanced technologies. I compared car engines of different year and concluded that engines are getting more and more loaded and oils are getting less and less viscous. In the final part, I reviewed the options for safe disposal and reuse of engine oils. avtomobilski motorji na notranje zgorevanje mazanje motorna olja aditivi standardi odpadna olja combustion engine lubrication engine oils additives standards waste oils true false false [M.
