Isitofu se-Diesel Fuel Injector 095000-8981 Denso Injector ye-Isuzu

1) Ngokwembono yenkqubo yokusebenza kwe-injini ye-diesel
UCaprotti et al.!7 wayekholelwa ukuba emva kokuba ivalufa yenaliti ye-injini ye-diesel ivalwe, kukho intsalela encinci yedizili kumngxuma wokutofa, kwaye i-cylinder iyanda ukwenza umsebenzi, okukhokelela ekwandeni kobushushu. kwi-cylinder, kwaye i-diesel isasazeka kwi-outlet ye-injection ye-injector kunye ne-injector fuel. Phezulu, ifilimu yeoli ye-liquid yenziwa; ukushisa okuphezulu kwigumbi lokutshisa kubangela ukuba i-fuel components ibe ngumphunga, kwaye i-fuel ifumana ukuphendulwa kweqondo lokushisa eliphezulu ukwenza idiphozithi yekhabhoni ye-viscous; i-soot, i-hydrocarbons ebilayo kakhulu kunye namacandelo e-oyile yokuthambisa eyenziwe ngexesha lenkqubo yokutsha iphezu kweediphozithi zekhabhoni. Ukuqokelela, izinga eliphezulu lokusabalalisa ioli ye-diesel, indawo ye-soot kwigumbi lokutsha kunye nezinye izinto ziqinisekisa ukukhawuleza kokubunjwa kwe-carbon deposit; ubukho besoot benza ukuba ubushushu bomphezulu we-injector buhlale buphezulu, buthintele ngempumelelo ifuthe lamafutha olwelo kwiidiphozithi zekhabhoni.
2) Ukususela kumbono wohlalutyo olusisiseko, uLepperhoff et al. yafumanisa ukuba iinqununu eziphambili ze-carbon deposits ziyizinto eziphilayo (ikhabhoni, i-hydrocarbons, i-oksijini kunye ne-nitrogen) kunye nenani elincinci lezinto ezingabonakaliyo (isulfure,), ngokuhlalutya kwe-elemental of carbon deposits; udonga kunye neoli Uqhagamshelwano oluphakathi kwamaconsi yimeko efunekayo yokwenziwa kweediphozithi zekhabhoni. Uninzi lwamajelo onxibelelwano ngama-hydrocarbons aneendawo zokubilisa eziphezulu. Inkqubo yokwenziwa kweediphozithi zekhabhoni inokwahlulwa kwiinkqubo ezimbini: ixesha lokungeniswa kunye nexesha lokukhula, njengoko kuboniswe kuMzobo 1. Phakathi kwazo: (1) Ngexesha lokungeniswa kwekhabhoni, ngenxa yokushisa okuphantsi kwendawo yodonga. , ii-hydrocarbons ezinamazinga aphezulu okubilisa ziyancitshiswa ukuze zenze ifilimu ye-viscous eludongeni, kwaye iincinci ezincinci zibhengezwa ngenxa yempembelelo yephepha elincangathi; (2) Ngethuba lokukhula kwe-carbon deposition, iinqununu kunye nezinye izinto ezibonakalayo zihlala zibhengezwa. Ubuninzi be-carbon deposition buyanda kwaye umphumo wokukhuthaza ubangela ukuba ukushisa komhlaba we-carbon deposition kwandiswe kwaye amandla okubopha ayancipha, okunciphisa ukongezwa kwamasuntswana amaninzi. Ngexesha elifanayo, ukuhamba kwe-fluctuation yegesi kubangela I-viscosity ye-carbon deposit iyanda. Emva kokuba idiphozithi yekhabhoni ifakwe eludongeni, phantsi kweempembelelo zokushisa kwexesha elide, ukuphendulwa kweekhemikhali ezifana nokubola, ukuchithwa kwamanzi, kunye ne-polymerization kuya kwenzeka, kwaye i-carbon deposit layer iya kuhlanganiswa ngakumbi.
