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 ngu-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 yokutywina ekupheleni kwe-injector. kwivalve yenaliti, inaliti yeshafti iphumela ngaphandle komngxuma, kwaye imilo yayo inokuguqulwa ibe yi-conical okanye i-cylindrical, ukuze umlomo ube setyhula. iqhekeza. Ngale ndlela, ikholamu 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, inaliti yeoli eninzi embindini kunye nenaliti yeoli encinci kamva), ifanelekile kwigumbi lokutsha le-vortex kwaye Igumbi lokutsha elineemfuno eziphantsi kumgangatho wokucoca idizili. Umzekelo, ububanzi be-nozzle ye-4125A4 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 phezulu nasezantsi intshukumo intshukumo yanda, ifuthe levalve yenaliti kumphezulu wokutywina conical ukwanda, uvakalelo lokuphendula yenaliti ivelufa yoxinzelelo lweoyile iyancipha.
