Umbhobho omtsha we-Injector Dlla149p1805 0433172099 ye-Fuel Injector 0445120168 0445120405 0445120406

(1) Emva kwesitofu esingundoqo sangaphambili, i-oil pump plunger iyaqhubeka ihambela ezantsi, ibangela ukuba uxinzelelo lwe-oyile kwigumbi loxinzelelo oluphezulu lwe-oyile lunyuke ngokukhawuleza. Xa uxinzelelo lwe-oyile lunyuka lube phezulu kunoxinzelelo lweoyile yokutofwa kwangaphambili (30MPa), ivalve yenaliti yenaliti ihambela phezulu kwaye naliti enkulu iqala. Ngenxa yokuba uxinzelelo lweoyile ye-oyile kwigumbi loxinzelelo oluphezulu lwe-oyile inyuka ngokukhawuleza okukhulu, uxinzelelo lweoyile kwigumbi loxinzelelo oluphezulu luya kuqhubeka nokunyuka ukuya kuthi ga kwi-205MPa.
(2) I-injection enkulu ye-fuel iphelile. Xa inkqubo yolawulo lwe-elektroniki iyeka ukunika amandla kwivalve yokulawula i-electromagnetic control valve, ivalve yenaliti yokulawula i-electromagnetic ishukuma iye ngasekunene phantsi kwesenzo sokubuya kwentwasahlobo yevalve yokulawula i-electromagnetic control valve, kwaye idibanisa igumbi le-oyile enoxinzelelo oluphezulu kunye i-oyile yoxinzelelo oluphantsi. Ngeli xesha, isibaso esikwigumbi leoyile elinoxinzelelo oluphezulu liqukuqela ukuya kwipaseji yeoyile enoxinzelelo oluphantsi ngokusebenzisa ivalve yolawulo lwe-electromagnetic, uxinzelelo lwamafutha kwigumbi loxinzelelo oluphezulu luyehla, ivalve yenaliti yenaliti iphinda isetyenziswe phantsi kwesenzo sombane. ukubuya kwentwasahlobo yevalve yenaliti yokutofa, kwaye i-plunger encedisayo ikwimo yesitofu. Ngaphantsi kwesenzo sokubuya kwentwasahlobo ye-valve yenaliti yeoli, i-oyile ye-oyile phakathi kwegumbi le-oyile yoxinzelelo oluphezulu kunye nentwasahlobo yokubuya ye-injection yenaliti ivaliwe, kwaye i-injection enkulu ye-fuel iphelile.
(3) I-oyile ingena kwigumbi leoli elinoxinzelelo oluphezulu. Xa icandelo elihlayo lekhamera lidibanisa nengalo ye-rocker, i-oil plunger yepompo ihambela phezulu phantsi kwesenzo sokubuya kwentwasahlobo ye-oil plunger, kwaye i-oil-high-pressure room yenza i-vacuum ngenxa yokunyuka kwevolumu. Ngeli xesha, i-fuel kwipaseji ye-oyile yoxinzelelo oluphantsi (edityaniswe nombhobho we-oyile yokungena) iqukuqela ukuya kwigumbi le-oyile enoxinzelelo oluphezulu ngevalve yokulawula i-electromagnetic de kube i-oyile yoxinzelelo oluphezulu izaliswe, ukuze ulungiselele i-oyile. inaliti yamafutha elandelayo.
