0445120087 I-Diesel Fuel Injector Common Rail Injector Assembly for Weichai

Isakhiwo kanye Nomgomo womjovo

I-fuel injector iyidivayisi enembayo enomshini wokunemba okuphezulu kakhulu, okudinga ububanzi obukhulu bokugeleza okuguquguqukayo, amandla aqinile wokulwa nokuvala nokunqanda ukungcoliswa, kanye nokusebenza okuhle kwe-atomization.Umgomo wokusebenza komjovo kaphethiloli ukuthola isignali yepulse yomjovo kaphethiloli ethunyelwe i-ECU ukuze ilawule ngokunembile inani lomjovo kaphethiloli.
I-injector, okuyi-valve ye-solenoid, ilawulwa yiyunithi yokulawula injini.I-petroli ngaphansi kwengcindezi yepayipi yokusabalalisa amafutha ingena ku-injector yamafutha, ngaphansi kwamandla entwasahlobo yokubuya, i-valve yenaliti isesimweni esivaliwe, futhi i-fuel injector ayikwazi ukujova uphethiloli;lapho i-ECU ilawula ikhoyili ye-solenoid yesijojo sikaphethiloli ukuze inikezwe amandla, inkambu kazibuthe ekhiqizwa ikhoyili ye-solenoid ishayela i-armature, I-valve yenaliti ikhuphukela phezulu, i-valve yenaliti iyavuleka, futhi umjovo kaphethiloli ujova uphethiloli.Ngokuvamile, ukuphakama kwevalve yenaliti yomjovo cishe ku-0.1mm.
Umgomo wesekethe yokulawula umjovo kaphethiloli uboniswa kuMfanekiso 1. Ikhoyili kagesi yesijojo sikaphethiloli iholela ezintanjeni ezimbili, ucingo olulodwa luwumthombo wamandla, olunikeza i-voltage engu-12V ngemva kokuvulwa kokhiye wokuthungela, kanti enye intambo umjikelezo waphansi olawulwa yiyunithi yokulawula ye-elekthronikhi.Lapho isitofu sikaphethiloli sidinga ukuvula umjovo kaphethiloli, iyunithi yokulawula i-electronic ECU ilawula ukumiswa kwalo mugqa nge-triode, futhi amandla kagesi ageleza kukhoyili kagesi, futhi umjovo kaphethiloli uvula umjovo kaphethiloli.Ngaso sonke isikhathi i-ECU ilawula ukuguquguquka kazibuthe kwentambo kagesi yomjovo ebizwa ngokuthi umjovo kaphethiloli wepulse ububanzi, osebangeni elingu-2~10ms.
