Abstract

Europske razine emisije za motore s unutarnjim izgaranjem u upotrebi kod necestovnih pokretnih strojeva definirane su razinama od I do V. Razina V, koja se uvodi Uredbom (EU) 2016/1628 primjenjuje se za sve nove motore koji se postavljaju na europsko tržište od početka 2019. godine. Uredbom se uvode stroži zahtjevi vezani uz ograničenja emisija plinovitih i krutih onečišćujućih tvari, obuhvaća se mnogo šire područje strojeva u odnosu na prethodne razine te se uvodi obaveza praćenja emisija u stvarnim (terenskim) uvjetima rada upotrebom prijenosnog sustava za mjerenje emisija (PEMS-a) kako bi se na ovom području dostigli ciljevi smanjenja onečišćenja kakvi se postavljaju u cestovnom sektoru. U cilju omogućavanja mjerenja emisija upotrebom PEMS-a kao relativno nove procedure u području necestovnih pokretnih strojeva, ovim je radom predstavljeno rješenje kojim se omogućuje smještaj PEMS opreme upotrebom nosača koji se sastoji od konzolnog prihvata na čvrste dijelove stroja i kućišta koje služi za smještaj, provođenje mjerenja i zaštitu mjerne i pomoćne opreme. Kako bi se postiglo takvo rješenje, prethodno je bilo potrebno detaljno definirati područje necestovnih pokretnih strojeva, zatim izabrati one strojeve koji su najčešći u upotrebi i za koje su definirana tehnička pravila u pogledu ispitnih postupaka koji se primjenjuju na PEMS (Uredba (EU) 2017/655), zatim proučiti vanjske konstrukcijske karakteristike izabranih strojeva na temelju primjeraka dostupnih na tržištu te provesti koncipiranje nosača i kućišta uzimajući u obzir različitosti mjera, oblika i smještaja vanjskih konstrukcijskih elemenata primjeraka. Kao prikladni primjerci za smještaj nosača izabrani su građevinski strojevi.

Abstract (english)

European emission standards for IC engines used in non-road mobile machinery (NRMM) are defined as Stage I to Stage V standards. Stage V, specified by Regulation 2016/1628 applies to all new engines placed to EU market from the beginning of 2019. Even more stringent requirements regarding gaseous and particulate matter emission limits are introduced by the Regulation, the Regulation covers much wider variety of NRMM that are not previously covered under existing legislation, and an obligation for emission monitoring of actual in use emissions applying PEMS is introduced, in order to ensure convergence with air quality targets established in the on-road sector. In order to make PEMS application emission measurements possible, as a relatively new procedure used in the NRMM sector, a right solution for PEMS installation that consists of an console that is being attached onto tough parts of a machine, and a housing that is used for equipment installation, for carrying out measurements and for protection of measuring and auxiliary equipment, is presented by the thesis. In order to achieve that solution, it was necessary to predefine the meaning of NRMM regarding its scope, to choose the most common machines in use, and to choose those machines that technical rules regarding testing procedures used in PEMS application are defined for (Regulation (EU) 2017/655), afterwards it was necessary to study design characteristics of chosen machines available on market and preform conceiving of the carrier based on dissimilarities in dimensions, shapes and arrangements regarding its construction elements. Construction machinery is chosen as an example of machines suitable for the carrier installation.
