I-BOSCH FUEL PUMP 0445020113 YAMA-CUMMINS

Izindlela zokunakekela injini ye-diesel fuel injection pump

(3) Hlola njalo futhi ulungise i-engeli yokuphakelwa kukaphethiloli esengaphambili yephampu yomjovo kaphethiloli kanye ne-engeli yesikhawu yokunikezwa kukaphethiloli yesilinda ngasinye.
Ngesikhathi sokusetshenziswa, ngenxa yokuxegiswa kwamabhawodi axhumayo okuxhumanisa kanye nokugqokwa kwe-camshaft nezingxenye zomzimba ze-roller, i-angle yokuhambisa uphethiloli kusengaphambili kanye ne-angle yokukhipha uphethiloli yesikhawu se-cylinder ngayinye kuvame ukushintshwa, okwenza ukushiswa kukadizili. uwoyela kubi nakakhulu, namandla nomnotho wenjini ye-diesel Ukusebenza kuba mpofu, futhi ngesikhathi esifanayo, kunzima ukuqala, ukusebenza akuzinzile, umsindo ongavamile nokushisa ngokweqile.Ekusetshenzisweni kwangempela, abashayeli abaningi banaka ukuhlolwa nokulungiswa kwe-engeli esele yokuphakelwa kukaphethiloli iyonke, kodwa bakushaya indiva ukuhlolwa nokulungiswa kwe-engeli yesikhawu sokuphakelwa kukaphethiloli (okubandakanya ukulungiswa kwe-engeli eyodwa yephampu kaphethiloli ngaphambi kwesikhathi), okuholela kulokho. ngemuva kokulungiswa okuphelele, nakuba ukunikezwa kukaphethiloli kwesilinda sokuqala kuvamile Kodwa-ke, ngenxa yokuguga kwezingxenye ze-camshaft kanye ne-roller yokudlulisela kwamanye ama-cylinders, ukunikezwa kukawoyela akukona ngempela isikhathi, okuzophinde kubangele ubunzima ekuqaleni. injini kadizili, amandla anganele, nokusebenza okungazinzile.Ngakho-ke, amaphampu omjovo kaphethiloli asetshenziswe isikhathi eside, ukunakwa okwengeziwe kufanele kukhokhwe ekuhlolweni nasekulungisweni kwe-angle yokunikeza uphethiloli.
(4) Hlola njalo futhi ulungise ukunikezwa kukaphethiloli kwesilinda ngasinye sephampu yomjovo kaphethiloli
Ngenxa yokuguga kwe-plunger coupling kanye nokuhlangana kwe-valve yokukhipha uwoyela, ukuvuza kwangaphakathi kukawoyela udizili kuzonciphisa noma kungalingani ukunikezwa kukaphethiloli kwesilinda ngasinye, okuzoholela ebunzimeni ekuqaliseni injini kadizili, amandla anganele, ukwanda kokusetshenziswa kukaphethiloli, kanye nokungazinzi. ukusebenza.Ngakho-ke, kuyadingeka ukuhlola njalo futhi ulungise ukunikezwa kukaphethiloli kwe-cylinder ngayinye yepompo yomjovo kaphethiloli ukuqinisekisa amandla enjini ye-diesel.Ekusetshenzisweni kwangempela, inani likaphethiloli elinikezwa isilinda ngalinye linganqunywa ngokubheka ukukhathala kwenjini kadizili, ukulalela umsindo wenjini, nokuzwa izinga lokushisa le-exhaust eningi.
