I-Diesel Injector Fuel Injector 0445110845 Bosch ye-Qingling

(1) Uma i-valve ye-solenoid yomjovo ingacushiwe, isihlalo sebhola le-valve sicindezela i-valve yebhola emgodini wokudonsa uwoyela wesihlalo se-valve, imbobo yokukhipha uwoyela iyavalwa, kanti uwoyela wesitimela ovamile awukwazi ukungena engxenyeni engenhla. wesihlalo se-valve. Umfutho ophakeme wesitimela ovamile uyakhiwa emgodini we-nozzle. Amandla ahlanganisiwe wesitimela esivamile ukucindezela okuphezulu ekucindezelweni kobuso bokugcina be-plunger yokulawula kanye ne-nozzle spring ingaphezulu kwamandla okuvulwa kukaphethiloli wokucindezela okuphezulu osebenza ku-cone ye-valve yenaliti, ngenxa yalokho, i-valve yenaliti iphoqelelwa esihlalweni se-valve futhi isiteshi sokucindezela okuphezulu sihlukanisiwe negumbi elivuthayo, sivalwe, futhi i-valve yenaliti ihlala ivaliwe.

(2) Lapho i-valve ye-solenoid iqala, ucezu lwe-armature kanye nesihlalo sebhola le-valve siyakhuphuka, i-valve yebhola iyavuleka, futhi imbobo yokukhipha uwoyela iyavuleka, okubangela ukwehla kwengcindezi yegumbi lokulawula, ngenxa yalokho, ukucindezela ku-piston nakho kwehla, lapho ukucindezela ku-piston namandla ahlangene e-nozzle spring yehliswa yaba ngaphansi kunomfutho osebenza ku-cone yokucindezela ye-valve yenaliti yomjovo (lapha umfutho kawoyela usekhona common rail high pressure), ivalve yenaliti izovulwa, bese uphethiloli ufafazwe egumbini elivuthayo ngembobo yombhobho. Lolu hlobo lokulawula okungaqondile kwe-valve inaliti yomjovo luthatha isethi ye-hydraulic pressure amplification system, ngoba amandla adingekayo ukuze uvule ngokushesha i-valve yenaliti ayikwazi ukukhiqizwa ngokuqondile yi-solenoid valve, okuthiwa umphumela wokulawula odingekayo ukuze uvule i-valve yenaliti ukuvula imbobo yokukhipha uwoyela nge-valve ye-solenoid ukunciphisa ukucindezela kwegumbi lokulawula, ngaleyo ndlela uvule i-valve yenaliti.

(3) Uma i-valve ye-solenoid ingacutshungulwa ukucisha kwamandla, amandla entwasahlobo e-solenoid valve azokwenza inkaba ye-armature kanye nesihlalo sebhola le-valve sicindezelwe phansi, futhi i-valve yebhola izovala imbobo yokukhipha uwoyela. Ngemuva kokuthi imbobo yokukhipha uwoyela ivaliwe, uphethiloli ungena emgodini wokulawula i-valve usuka embotsheni yokufaka uwoyela ukuze usungule umfutho kawoyela, le ngcindezi ingumfutho wesitimela, le ngcindezi isebenza ebusweni bokuphela kwe-plunger ukukhiqiza ukucindezela okuya phansi, kuhambisana namandla aphumayo. wesiphethu sombhobho mkhulu kunokucindezela kukaphethiloli womfutho ophezulu osebenza kuconi yevalvu yenaliti emgodini wombhobho, ukuze ivalve yenaliti yomlomo ivaleke.

(4) Ngaphezu kwalokho, ngenxa yomfutho ophakeme kaphethiloli, ukuvuza kuzokwenzeka kuvalvu yenaliti kanye nasezindlini, futhi lawa mafutha avuzayo azogelezela endaweni yokubuya uwoyela yomjovo ngembobo yokubuyisela uwoyela.
