I-New Diesel Fuel Injector 28490086 ye-Jmc Transit Qingling

Izijovo zikaphethiloli zezinjini zikadizili ezihamba ngesivinini esikhulu nezincane ngokuvamile zinezinhlobo ezimbili: uhlobo lwe-pintle kanye nohlobo lwezimbotshana. Ama-injection enaliti e-axial asetshenziswa kuma-vortex noma emakamelweni avuthayo angaphambi komlilo. Inombolo yezimbobo zomjovo ngu-1, futhi ububanzi bokuvula bungaphezu kuka-1mm. Lolu hlobo lomjovo lusebenza ngendlela enokwethenjelwa, futhi izimbobo zokujova akulula ukuvinjwa amadiphozithi e-carbon, kodwa ukusebenza kahle kokushisa kuphansi futhi ukusetshenziswa kukaphethiloli kuphezulu. Izinjini ze-Domestic 125 kanye nezinjini zikadizili eziyi-146 zingaphansi kwalesi sigaba. Ama-injection e-Multi-hole asetshenziswa emakamelweni okuvutha umjovo oqondile. Ingakwazi ukufafaza izifutho eziningana nge-taper encane kanye nebanga elide. Lolu hlobo lomjovo lusebenza kahle kakhulu ekushiseni futhi luwonga uphethiloli. I-fuel injector yenjini ye-diesel yasekhaya engu-135 inezimbobo eziningi ze-nozzle ezinobubanzi obungu-0.35mm. Ukuhlangana kwevalvu yenaliti yomjovo kaphethiloli kunembe uma kuqhathaniswa, futhi imvume yayo efanayo ingu-0.002 ~ 0.004mm kuphela. Uma kukhona ukungcola emafutheni edizili, ivalve yenaliti izobambeka. Ngaphezu kwalokho, inhloko ye-fuel injector ibilokhu ithintana negesi ephezulu yokushisa kanye ne-high-pressure ekamelweni lokushisa, okwenza i-valve yenaliti ikhule kancane kancane futhi iguqule, futhi ithinte ukusebenza okuvamile kwe-locomotive. Lapho i-injector isebenza, i-cone cone ebusweni bomzimba we-valve yenaliti ivame ukuthintwa yi-valve yenaliti, kuhlanganiswe nomjovo oqhubekayo wokugeleza kawoyela ocindezelwe kakhulu ukusuka kule ndawo, indawo yekhoni izovela imihuzuko namabala - kancane kancane ilahlekelwe ukuvala, bese uqala ukuconsa amafutha . Lapho izinga lokushisa lomshini liphansi, ipayipi le-exhaust lizokhipha intuthu emhlophe, futhi lapho izinga lokushisa lomshini likhuphuka, lizophenduka intuthu emnyama, futhi ngezinye izikhathi ipayipi le-exhaust lizokhipha imisindo engavamile yokuqhuma.
