Umgaqo wokusebenza wesitofu samafutha
1. Xa ivalve ye-solenoid ye-injector ingavuswanga, i-valve encinci icinezela ivalve yebhola phantsi kwepleyiti yepivot kwivalve yokukhulula.
Kwimbobo yeoli, i-oil drain hole ivaliwe kwaye umzila oqhelekileyo uxinzelelo oluphezulu lwenziwa kwigumbi lokulawula i-valve.Ngokufanayo, isiporo esiqhelekileyo soxinzelelo oluphezulu lwenziwe kumngxuma wombhobho.Ngenxa yoko, i-valve yenaliti inyanzelekile ukuba ingene kwisihlalo se-valve kwaye ihlukanise kwaye itywine ishaneli yoxinzelelo oluphezulu ukusuka kwigumbi lokutsha, kwaye i-valve yenaliti ihlala ivaliwe.
2. Xa i-valve ye-solenoid ivuliwe, i-pivot plate ihambela phezulu, ivalve yebhola iyavuleka kwaye umngxuma we-oyile uyavulwa.
Ngeli xesha, uxinzelelo kwigumbi lokulawula luyancipha, kwaye ngenxa yoko, uxinzelelo kwipiston luyancipha.Nje ukuba isiphumo soxinzelelo lwepiston kunye nomthombo wombhobho wehla ngaphantsi koxinzelelo olusebenza kwikhowuni yoxinzelelo lwevalve yenaliti yombhobho wenaliti yamafutha (uxinzelelo lwe-oyile apha iseluxinzelelo oluqhelekileyo lukaloliwe oluphezulu), ivalve yenaliti iya kuba ivulwe kwaye amafutha azakutofwa kwigumbi lokutsha ngomngxuma wombhobho.Olu lawulo olungathanga ngqo lwe-valve yenaliti ye-injector luthatha isethi ye-hydraulic pressure amplification system, kuba amandla afunekayo ukuvula ngokukhawuleza i-valve yenaliti ayikwazi ukuveliswa ngokuthe ngqo kwi-solenoid valve.Into ebizwa ngokuba ngumsebenzi wokulawula ofunekayo ukuvula i-valve yenaliti kukuvula i-oil drain hole ngokusebenzisa i-solenoid valve ukunciphisa uxinzelelo kwindawo yokulawula, ukuze uvule i-valve yenaliti.
3. Emva kokuba i-valve ye-solenoid ivaliwe, ayiyi kuqaliswa.Amandla amancinane asentwasahlobo aya kutyhala ezantsi undoqo wevalve ye-solenoid kunye nebhola
Ivalve ivala umngxuma wokukhupha amanzi.Emva kokuba i-oyile yokukhupha i-oyile ivaliwe, i-fuel ingena kwigumbi lokulawula i-valve ukusuka kwi-oil inlet hole ukuseka uxinzelelo lwe-oyile.Olu xinzelelo luxinzelelo lukaloliwe lwamafutha.Olu xinzelelo lusebenza ekupheleni kobuso beplunger ukuvelisa uxinzelelo oluya ezantsi.Ukongeza, amandla aphuma kumthombo wombhobho mkhulu kunoxinzelelo lwepetroli yoxinzelelo oluphezulu kwigumbi lombhobho kumphezulu weconical wevalve yenaliti, ukuze kuvalwe ivalve yenaliti yomlomo.
4.Ngaphezu koko, ngenxa yoxinzelelo oluphezulu lwamafutha, ukuvuza kuya kwenzeka kwi-valve yenaliti kunye ne-plunger yokulawula, ioli evuzayo iya kuqukuqela kwi-oyile ebuyisela i-oyile.
