I-New Injector Nozzle Dlla149p1805 0433172099 ye-Fuel Injector 0445120168 0445120405 0445120406

(1) Ngemva komjovo oyinhloko womjovo wangaphambili, i-plunger yepompo kawoyela iyaqhubeka nokuya phansi, okubangela umfutho kawoyela egunjini likawoyela elinomfutho omkhulu ukuthi ukhuphuke ngokushesha. Uma umfutho kawoyela ukhuphuka ube phezulu kunomfutho kawoyela womjovo wangaphambi komjovo (30MPa), ivalvu yenaliti yomjovo iya phezulu bese kuqala umjovo omkhulu. Ngenxa yokuthi ingcindezi kawoyela kawoyela egumbini likawoyela elinengcindezi ephezulu ikhuphuka ngokushesha okukhulu, ingcindezi kawoyela egumbini likawoyela elinengcindezi ephezulu izoqhubeka nokukhuphuka ifike ku-205MPa.
(2) Umjovo omkhulu kaphethiloli uyaphela. Lapho uhlelo lokulawula i-elekthronikhi luyeka ukuhlinzeka amandla ku-valve yokulawula i-electromagnetic control, i-valve yenaliti ye-electromagnetic control valve iya kwesokudla ngaphansi kwesenzo sokubuya kwentwasahlobo ye-electromagnetic control valve valve, bese ixhuma igumbi likawoyela elinengcindezi ephezulu uwoyela ongaphansi kwengcindezi. Ngalesi sikhathi, uphethiloli osegumbini likawoyela elinengcindezi ephezulu ugelezela endaweni kawoyela enengcindezi ephansi ngokusebenzisa i-valve yokulawula i-electromagnetic, ingcindezi kaphethiloli egumbini likawoyela elinengcindezi ephezulu iyehla, i-valve yokujova uphethiloli iqala kabusha ngaphansi kwesenzo intwasahlobo yokubuya yevalve inaliti yokujova, futhi i-plunger eyisizayo isesimweni sokujova. Ngaphansi kwesenzo se-spring yokubuya ye-valve yenaliti yamafutha, umzila kawoyela phakathi kwegumbi likawoyela elinengcindezi ephezulu kanye nesiphethu sokubuya se-valve yenaliti yomjovo ivaliwe, futhi umjovo omkhulu kaphethiloli uyaphela.
(3) Amafutha angena egumbini likawoyela elinomfutho ophezulu. Lapho ingxenye eyehlayo yekhamera ithinta ingalo ye-rocker, i-pump oil plunger ihambela phezulu ngaphansi kwesenzo se-splunger ebuyayo ye-pump oil plunger, futhi igumbi likawoyela elinomfutho ophezulu likhiqiza i-vacuum ngenxa yokwanda kwevolumu. Ngalesi sikhathi, uphethiloli osephaseji likawoyela elinomfutho ophansi (oxhunywe nepayipi lokungenisa uwoyela) ugelezela egumbini likawoyela elinomfutho ophezulu ngokusebenzisa i-valve yokulawula ugesi kuze kugcwaliswe igumbi likawoyela elinomfutho ophezulu, ukuze lilungiselele umjovo kaphethiloli olandelayo.
