Diesel Injector Fuel Injector 0445120183 Bosch yeDongfengdfl 4.8

Kugadzira Modhi yeFuel Injection process Kubudirira Analysis yeInjector yeDiesel Engines(chikamu 2)

Zvakare, kuti uvandudze maitiro ejekiseni, zvinodikanwa kuwedzera kudzvanywa kwejekiseni, uko kunoperekedzwa nekuwedzera kwekuyerera kwemafuta kuburikidza neatomizing orifices (zvichikonzera kuyerera kwekuyerera) uye kupararira velocity yejeti remafuta mukati. iye CC.

Kuparara kwejeti yemafuta kunotanga pakarepo paatomizing orifice. Izvi zvinhu zvinotungamira kune yakagadziridzwa mhando yemafuta atomization, iyo inoratidza kudikanwa kwekudzidza dynamics yeatomizer. Nekudaro, pane chinonetsa muhumwe uye huwandu hwekufungidzira kwekuparadzirwa kwemafuta, iro parizvino basa rakasimba uye rinopedza simba. Izvo hazvigoneke kuwana chaiwo mafuta atomization maitiro pasina perofrming matatu-dimensional modelling, iyo inoda yakakwirira uye yepamusoro nhanho yeruzivo rwemapakeji ekuverenga.

2Kusarudza kutenderera kunorara pamwe neiyo pressure spectrum

Mukugadzirisa mamwe mabasa ekufungidzira sarudzo dzakaenzaniswa nemhando yadzo yeatomization yemafuta, madhayagiramu ekuyerera kana dhiyagiramu yekumanikidza kumusoro kweatomizing orifices inogona kukwana. Semuenzaniso, kuongororwa kwesimba re electrohydraulic injector (EHI) parameters inogona kuitwa uchishandisa kukosha kwekutenderera kwekupa uye nguva dzejekiseni kutanga uye kupera kwechiratidzo chimwechete chekudzora. Sarudzo yejekiseni ine yakakwira kutenderera kutenderera chiyero, yakapa kunonoka kwakaenzana kwenguva dzejekiseni kutanga uye kupera zvichienderana nenguva yechiratidzo chekutonga kutanga uye kupera, inokurumidza, uye, semhedzisiro, inonyanya kufarirwa, kubvira. zvinozivikanwa pachine nguva kuti mhando yekutakura mafuta inovandudza nekuwedzera EHI yekushanda kumhanya. Nekudaro, kazhinji, hapana ruzivo rwekuwirirana pakati peiyo modhi inobuda paramita uye mafuta atomization yemhando, izvo zvinoda kushandura nzira yekufanotaura.
