Isitofu se-Diesel Injector ye-Fuel 0445120332 Bosch ye-Cummins 6.7 injini

uhlobo lwesakhiwo sesitofu
I-injector yodidi lomngxuma inemingxuma eyi-1 ~ 7 ububanzi be-0.15 ~ 0.70 mm, enokuthi itshize i-angle ye-cone ethile kwaye inoluhlu olude.Ukukhethwa kohlobo lomngxuma kufuneka kugqitywe luhlobo lwegumbi lokutshisa.Ngokomzekelo, i-injini ye-diesel ye-6120 isebenzisa i-injector enemingxuma emibini kunye nobubanzi bomngxuma we-0.4 mm kunye noxinzelelo lwe-injection ye-17-150 kPa.I-injini ye-6135 yi- @-shaped combustion chamber esebenzisa i-injector enemingxuma emi-4 enobubanzi be-0.35 mm kunye noxinzelelo lwe-injection ye-16 660 kPa.Ulwakhiwo lwesitofu somngxuma ikakhulu luqulunqwe ngumzimba wesitofu, ikhowuni yokutofa kwe-fuel, ivalve yesitofu se-cone, umzimba wevalufa yesitofu, intonga ye-ejector, ityhubhu elawula uxinzelelo, uxinzelelo olulawula isikhonkwane sokungena kwi-oyile, isihluzo. element kunye nebholiti yombhobho we-oyile yokubuyisela njalo njalo.Uxinzelelo ekuqaleni kwesitofu samafutha luxhomekeke kumandla okuqinisa kwangaphambili oxinzelelo olulawula intwasahlobo.Inokulungiswa sisikrufu sokulawula uxinzelelo.Ngexesha lenkqubo yokutofa ngamafutha, indawo encinci yedizili evuzayo iya kumpompoza kwivalve yenaliti.
Isitofu se-pintle sinomngxuma omnye wenaliti enobubanzi obuyi-1 ~ 3 mm.Ngenxa yobubanzi bomngxuma omkhulu, uxinzelelo lwenaliti ye-fuel luphantsi, ngokubanzi 9800 ~ 11760 kPa, olulungele igumbi lokutsha elahlulwe.Isakhiwo se-pintle injector kunye ne-orifice injector ifana ngokufanayo.Umahluko kukuba i-cone yokutywina yevalve yenaliti yandisa icandelo le-pintle, kwaye ububanzi buncinci kunomngxuma wombhobho.I-annular slit yenziwa phakathi kwepintle kunye nomngxuma.Iimilo ze-pintle ziyi-cylindrical kunye ne-conical inverted.Xa umphezulu wekhowuni yokutywina wevalve yenaliti ushiya isihlalo sevalve, inaliti yeoli iqala, kwaye ikholamu yeoli ikwimo yeringi engenanto.I-angle yokutofa yepintle ejijekileyo ejijelweyo inkulu ngokwentelekiso.Xa i-injector ye-fuel iqala ukufaka i-fuel kwaye iyeke ngokukhawuleza ukujova i-fuel, i-pintle i-inject hole, kwaye umthamo we-injection ye-fuel incinci, enokunciphisa umsebenzi onzima we-injini ye-diesel kunye nokunciphisa ixesha lokuzaliswa.Lindela.Olu hlobo lwesitofu kulula ukusetyenzwa.Umngxuma wombhobho akukho lula ukuwuvala.Iindleko zokuvelisa ziphantsi kwaye ukusilela kuncinci.
