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 kanye 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 yokujova kuzoholela ekwenyukeni kokulahleka kokugeleza komjovo kaphethiloli, ukwenziwa kwe-atomu okungekuhle 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: amaholoholo omile futhi abushelelezi amanzi.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 no-S..

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

Kumagai et al.ihlolisise umthelela we-Zn element kuwoyela kaphethiloli wenjini eyodwa ye-cylinder diesel endaweni yokubeka i-carbon emgodini we-jet, futhi yathola ukuthi noma ngabe i-Zn element yayiqukethe 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.
