Ikhwalithi Ephakeme I-Common Rail Diesel /Fuel Injector Nozzle DLLA145SM012

I-Fuel injector iyingxenye eyinhloko yesistimu yomjovo kaphethiloli wenjini, futhi isimo sayo sobuchwepheshe sinethonya elikhulu ekusebenzeni okuvamile kwenjini. Ngoba indawo yokusebenza yomjovo yimbi ngokwedlulele, ibhekene ngqo nezinga lokushisa eliphezulu nokushiswa komfutho ophezulu

Ekamelweni, ifilimu kawoyela ku-nozzle ithambekele ku-oxidation, i-polymerization nokunye ukusabela, okuholela ekuqongeleleni kwekhabhoni ku-nozzle. Ucwaningo olukhona luthole ukuthi ukufakwa kwekhabhoni emigodini yomjovo kuzoholela ekwenyukeni kokulahleka kokugeleza komjovo kaphethiloli, ukungasebenzi kahle kwe-athomu kanye nekhwalithi yokuvutha, kanye nokwehla kwamandla enjini nomnotho. UZhou Jianwei et al. wafunda izici zokubeka ikhabhoni zomjovo wenjini kaphethiloli womjovo oqondile futhi wathola ukuthi idigri ye-carbon deposition yembobo ngayinye yomjovo yayihlukile, futhi ukubekelwa kwekhabhoni kwabonisa ama-morphologies amabili: okumaholoholo okomile nokumanzi bushelelezi. Liaquat et al. ihlaziye i-carbon deposition emigodini yejethi yesilinda esisodwa sikadizili ngemuva kokuhlolwa kokuqina kwamahora angama-250, yathola ukuthi ukubekelwa phansi kwekhabhoni kwasatshalaliswa kakhulu phezulu komjovo, okuhlanganisa u-C, O, Zn kanye no-S..

Ukwakheka kwe-elementi. Barbour et al. ihlaziye izici ze-morphology yediphozi ye-carbon emgodini ngemva kokusika imbobo yomjovo wenjini ethile kadizili ngemva kokusebenza amahora angu-60, futhi yathola ukuthi kunongqimba lwediphozithi yekhabhoni emahhadla ngaphakathi kwembobo yomjovo yediphozithi ye-carbon.

Kumagai et al. uhlole umthelela we-Zn element kuwoyela kaphethiloli wenjini ye-cylinder eyodwa yedizili endaweni yokubeka i-carbon emgodini we-jet, futhi wathola ukuthi noma ngabe i-Zn element yayiqukethwe noma cha, kwakukhona ukuchithwa kwekhabhoni okuningi ohlangothini lokuphuma kwe-jet hole kune ohlangothini lokungena, kodwa lapho amafutha equkethe i-Zn element, izinhlayiya ze-carbon deposition emgodini zazizincane futhi zifana ngendlela efanayo.
