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, i-valve ye-cone ye-fuel cone, umzimba we-injection ye-fuel, intonga ye-ejector, ityhubhu elawula uxinzelelo, uxinzelelo olulawula ukungena kwe-oyile edibeneyo, 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 yamafutha 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 ukujova i-fuel kwaye iyeke ngokukhawuleza i-fuel injecting, 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.
