I-Diesel Injector Fuel Injector 0445120289 Bosch for Cummins Isbe Isde Qsb6.7

Omnye umzekelo yi-double-hole evaliweyo yesitofu esisetyenziswa kwi-injini ye-diesel ye-6120.Ububanzi bomngxuma wenaliti yi-0.42mm kunye noxinzelelo lwe-injection yi-17.5M Pa. Umgaqo wokusebenza we-shaft inaliti ye-injector iyafana naleyo ye-injector yomngxuma, kuphela isakhiwo esahlukileyo: phantsi kwe-cone yokutywinwa kwinqanaba elisezantsi. kwivalve yenaliti, inaliti ye-shaft iphuma emngxunyeni, kwaye imilo yayo inokuguqulwa i-conical okanye i-cylindrical, ukwenzela ukuba umlomo ube yi-slit circular.Ngale ndlela, ikholomu yesitofu iya kuba yi-cone okanye ikholamu engenanto.Ubungakanani bomngxunya wenaliti yomngxuma kunye ne-engile yokutofa ixhomekeke ekuphakameni kunye nokumila kwenaliti ye-shaft, ngoko ke ukusetyenzwa kwenaliti ye-shaft kuyafuneka ukuba kuchaneke kakhulu.Idayamitha yesitofu senaliti yomngxuma inkulu (ngokubanzi yi-1 ~ 3mm), uxinzelelo lwenaliti luphantsi (ngokubanzi yi-10 ~ 14MPa), isakhono sokuzicoca sinamandla (umngxuma wokutofa akukho lula ukuqokelela ikhabhoni kunye nokuvaleka), iimpawu zokutofa zilungile (dibana Iimfuno zenaliti yeoli encinci ekuqaleni, naliti yeoli eninzi embindini kunye nenaliti yeoli encinci emva koko), ifanelekile kwigumbi lokutsha le-vortex kunye negumbi lokutshisa elinomlilo elinemfuno ephantsi kumgangatho wokucoca idizili.Ngokomzekelo, i-nozzle ye-4125A4 ye-injini ye-diesel yi-1.5mm kunye noxinzelelo lwe-injection yi-12.7M Pa. Ezintathu, i-inertia ephantsi yesitofu se-fuel injector intonga inde, indawo yoxinzelelo elawula intwasahlobo ikude kwivalve yenaliti, ukuze ivelufa yenaliti up and down intshukumo intshukumo yanda, impembelelo yevalve yenaliti kumphezulu conical yokutywina ukwanda, uvakalelo lokuphendula lwevalve yenaliti kuxinzelelo lwe-oyile luyancipha.
