САЖЕТАК / ABSTRACT:

Dvotaktni dizel motori predstavljaju vitalnu komponentu pogona trgovačkih brodova, ali njihova upotreba teške nafte dovodi do ozbiljnih problema zagađenja okoline. Ovaj rad istražuje uticaj različitih vrsta goriva na potrošnju i izduvne emisije brodskog dvotaktnog dizel motora. U cilju smanjenja negativnih uticaja, istražene su alternative u vidu kvalitetnih dizel goriva i njihovih mješavina sa biodizelom. Primijenjena je eksperimentalna metoda za analizu performansi dvotaktnog dizel motora, najčešće korišćenog pogona u trgovačkom pomorskom saobraćaju. Korišćeni su čisti euro dizel i različite smjese euro dizela sa biodizelom dobijenim od otpadnog suncokretovog ulja u različitim odnosima (7%, 20%, 25%). Praćene su izduvne emisije, uključujući CO, CO2, NOx, SO2 i O2, tokom četiri različita režima rada motora. Eksperiment je sproveden na školskom brodu Jadran, koji je u sastavu Mornarice Vojske Crne Gore, dok je brod bio privezan u luci baziranja. Opterećenje motora, prilikom rada na vezu broda u luci, predstavlja posebnu pogonsku karakteristika motora koja se u literaturi naziva karakteristika teškog propelera. Rezultati ovog istraživanja pružaju uvid u efikasnost različitih vrsta goriva na performanse i ekološki aspekt rada dvotaktnog dizel motora u realnim eksploatacionim uslovima pomorskog saobraćaja.
