Ucwaningo Ngethonya Le-Injector Hole Carbon Deposition on Diesel Engine Injection Pressure

Ngesikhathi sokusetshenziswa kwezinjini ze-diesel, inkinga yokubeka i-carbon emigodini ye-nozzle yama-injection kaphethiloli nayo iyenzeka. Ngemuva kokuthi i-valve yenaliti ivaliwe, amafutha asele aphethiloli ngaphakathi kwembobo yomjovo enza ifilimu encane yamafutha, eqhekeka kalula ukushisa okuphezulu kanye nemvelo yokucindezela okuphezulu futhi ikhiqize amadiphozi ekhabhoni. Ngemuva kokuthi amadiphozithi ekhabhoni esenziwe, anqwabelana ngaphakathi futhi aphume emigodini yomlomo, aguqule ukwakheka kwembobo yembobo yasekuqaleni, kuthinte ukugeleza okujwayelekile kukawoyela wedizili, kuphazamise imodi yokuthuthukisa isifutho, futhi kuthinte kakhulu izici zesifutho nezici zomlilo. izinjini diesel. Ucwaningo lwakwamanye amazwe lubonise ukuthi ngemva kokufakwa kwekhabhoni emigodini ye-nozzle ye-injector, umthamo womjovo kaphethiloli uyancipha, ikhwalithi ye-spray iyancipha, ukusebenza kahle komlilo kuyancipha, kanye NO. ukwanda kokukhishwa kwegesi. Ukuhlolwa kukaBirgel et al. ebhentshini lenjini ye-cylinder eyodwa libonisa ukuthi ngemva kokufaka i-carbon emigodini yomjovo, isilinganiso esibonisiwe sokucindezela kusilinda sehla ngobuningi obungu-12.2%. Ukuhlolwa kukaKumagai et al. ebhentshini lenjini engu-4-cylinder libonise ukuthi i-torque yenjini yehle ngo-9% ngemuva kokufaka i-carbon emigodini yomjovo.
I-fuel injection system ingenye yezingxenye ezibalulekile zenjini, futhi iyinhliziyo yenjini yonke. Izici zayo zomjovo zithinta ngqo ukwakheka kwengxube kusilinda kanye nekhwalithi yokuvutha7. Amazwe angaphandle enze umsebenzi othile mayelana nomthelela wokufakwa kwekhabhoni yomjovo esifuthweni nasekushiseni, kodwa kukhona izifundo ezimbalwa ngomthelela wokucindezela komjovo. Kuleli phepha, kusetshenziswa ibhentshi lokuhlola iphampu yomjovo kaphethiloli, isijovo sikaphethiloli esisha kanye nesijovo sikaphethiloli esifakwe ngekhabhoni kwasetshenziswa ukwenza ukuhlolwa komjovo kaphethiloli, kanye nomthelela wediphozithi yekhabhoni embobeni yomlomo womjovo kuphethiloli. umfutho womjovo wenjini kadizili wahlaziywa. kanye nomthelela wezimpawu zokuvutha.
