I-Diesel Injector Fuel Injector 0445120264 Bosch for Foton Auv Bus Auman Forland Aumark 2000 Cummns 150t1

Okunye okubaluleke kakhulu ivalvu yenaliti kanye nomzimba wevalvu yenaliti eyenziwe ngensimbi enekhwalithi ephezulu (evame ukwaziwa ngokuthi umjovo womjovo kaphethiloli noma ikhanda lomjovo kaphethiloli), kokubili ndawonye kubize izithandani zevalve yenaliti. Lapho umjovo usebenza, uwoyela we-diesel onengcindezi ephezulu ophuma empompeni yomjovo ungena kumjovo ngejoyinti leshubhu, bese ungena ekamelweni likawoyela we-annular high pressure phakathi nomzimba wevalve yenaliti ngokusebenzisa umgudu wokungenisa uwoyela emzimbeni womjovo. Ingcindezi kawoyela isebenza kwikhoni yokucindezela yevalvu yenaliti futhi yenza i-axial thrust eya phezulu kuvalvu yenaliti. Lapho i-thrust inkulu kunengcindezi yokuqina yangaphambi kokucindezela kwentwasahlobo elawulayo kanye namandla okungqubuzana phakathi kombhangqwana wevalve yenaliti (okuncane kakhulu). I-valve yenaliti ihanjiswa ibheke phezulu, i-cone yokuvala yengxenye engezansi ye-valve yenaliti iyasuswa eringini ye-conical yomzimba we-valve yenaliti, futhi imbobo yomjovo iyavulwa, ukuze uphethiloli wedizili ujovwe egumbini elivuthayo. umfutho ophezulu. Lapho iphampu yomjovo kaphethiloli iyeka ukunikeza uwoyela, ukucindezela kuphaseji kawoyela ocindezelayo kwehla ngokushesha, futhi ivalve yenaliti ibuya ngesikhathi ngaphansi kwesenzo sokucindezela kwentwasahlobo elawula intwasahlobo ukuvala imbobo yejethi. Inombolo yezimbobo ze-orifice injector inkulu (ngokuvamile i-1 ~ 8), ububanzi be-orifice buncane (ngokuvamile 0.2 ~ 0.8mm), ukucindezela komjovo kuphezulu (ngokuvamile 17 ~ 22MPa), ikhono lokuzihlanza impofu (i-orifice kulula ukuqoqa ikhabhoni nepulaki), futhi ikhwalithi yesihlungi sikadizili iphezulu. Ilungele igumbi lokuvutha komjovo oqondile odinga ikhwalithi ephezulu yesifutho. Isibonelo, i-5-hole evaliwe i-fuel injector esetshenziswa ku-CA6110-2 injini ye-diesel inobubanzi obungu-0.32mm kanye nengcindezi yomjovo engu-17.2MPa.
