20.500.12556/DKUM-89371 The ǂeffect of fuel quality on cavitation phenomena in common-rail diesel injector—a numerical study Plastic is one of the most widely used materials worldwide. The problem with plastic arises when it becomes waste, which needs to be treated. One option is to transform plastic waste into synthetic fuels, which can be used as replacements or additives for conventional fossil fuels and can contribute to more sustainable plastic waste treatment compared with landfilling and other traditional waste management processes. Thermal and catalytic pyrolysis are common processes in which synthetic fuels can be produced from plastic waste. The properties of pyrolytic oil are similar to those of fossil fuels, but different additives and plastic stabilizers can affect the quality of these synthetic fuels. The quality of fuels and the permissible particle sizes and number density are regulated by fuel standards. Particle size in fuels is also regulated by fuel filters in vehicles, which are usually designed to capture particles larger than 4 µm. Problems can arise with the number density (quantity) of particles in synthetic fuels compared to that in fossil fuels. The present work is a numerical study of how particle size and number density (quantity) influence cavitation phenomena and cavitation erosion (abrasion) in common-rail diesel injectors. The results provide more information on whether pyrolysis oil (synthetic fuel) from plastic waste can be used as a substitute for fossil fuels and whether their use can contribute to more sustainable plastic waste treatments. The results indicate that the particle size and number density slightly influence cavitation phenomena in diesel injectors and significantly influence abrasion. plastic waste synthetic fuels pyrolytic oil common rail cavitation erosion particles plastični odpadki sintetična goriva pyrolytic oil skupni vod kavitacija erozija delci true false true MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/journal/sustainability © 2024 by the authors Članek v reviji 2024-07-05 09:40:43 2024-07-05 09:40:44 2025-07-30 14:49:50 0000-00-00 00:00:00 2024 0 0 18 str. iss. 12, [article no.] 5074 Vol. 16 June 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2024-04-25 2024-06-11 2024-06-14 662:620.193.16 200736771 10.3390/su16125074 2071-1050 sustainability-16-05074-v2.pdf sustainability-16-05074-v2.pdf 1 D4EF2114D1BC6A6BF21E4F1F0DA9B45C c5d0ff55d49b5246a6060a171d4b884f420ea1b3b23cc0afb8850c17e05252ee 7279b218-3aa4-11ef-bcfd-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=181170 https://www.mdpi.com/2071-1050/16/12/5074 0 955059ac-3aa4-11ef-bcfd-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=181171 Fakulteta za strojništvo 0 0 0
