I-Diesel Injector Fuel Injector 095000-8981 Denso Injector ye-Isuzu

1) Ngokombono wenqubo yokusebenza kwenjini ye-diesel
UCaprotti et al.!7 wayekholelwa ukuthi ngemva kokuvalwa kwevalvu yenaliti yomjovo wenjini kadizili oqondile, kunensalela encane kadizili emgodini womjovo, futhi isilinda siyanwebeka ukuze senze umsebenzi, okuholela ekwenyukeni kwezinga lokushisa. kusilinda, futhi udizili usakazekela lapho kuphuma khona imbobo yomjovo kanye nomjovo wamafutha. Phezulu, kwakhiwa ifilimu yamafutha ewuketshezi; izinga lokushisa eliphezulu ekamelweni elivuthayo libangela ukuba izingxenye zikaphethiloli zihwamuke, futhi uphethiloli ubhekana nokusabela kokuqhekeka okushisa okuphezulu ukuze zenze i-viscous carbon deposits; i-soot, ama-hydrocarbon abilayo kakhulu kanye nezingxenye zikawoyela wokugcoba ezikhiqizwa ngesikhathi senqubo yokuvutha ziphezu kwamadiphozithi ekhabhoni. Ukunqwabelana, izinga eliphezulu lokusatshalaliswa kwamafutha edizili, imvelo yensizi egumbini elivuthayo nezinye izici ziqinisekisa isivinini sokwakheka kwediphozithi yekhabhoni; ukuba khona komsizi kwenza izinga lokushisa eliphezulu lomjovo lihlale liphakeme, kuvimbela ngempumelelo umthelela wamafutha oketshezi kumadiphozithi ekhabhoni.
2) Ngokombono wokuhlaziya okuyisisekelo, uLepperhoff et al. ithole ukuthi izingxenye eziyinhloko zamadiphozi ekhabhoni kwakuyizinto eziphilayo (ikhabhoni, ama-hydrocarbon, umoya-mpilo ne-nitrogen) kanye nenani elincane lezinto ezingaphili (sulphur, ), ngokuhlaziywa okuyisisekelo kwe-carbon deposits; udonga namafutha Indlela yokuxhumana yamaconsi yisimo esidingekayo sokwakheka kwe-carbon deposits. Iningi lemidiya yokuxhumana ama-hydrocarbon anamaphuzu abilayo aphezulu. Inqubo yokwakheka kwe-carbon deposits ingahlukaniswa ngezinqubo ezimbili: isikhathi sokungeniswa kanye nesikhathi sokukhula, njengoba kuboniswe kuMfanekiso 1. Phakathi kwazo: (1) Ngesikhathi sokungeniswa kwe-carbon deposition, ngenxa yokushisa okuphansi kwendawo yodonga. , ama-hydrocarbon anamaphuzu aphezulu abilayo ayafingqiwe ukuze enze ifilimu ye-viscous odongeni, futhi izinhlayiya ezincane ziyakhangiswa ngenxa yomphumela wephepha elinamathelayo; (2) Ngesikhathi sokukhula kwe-carbon deposition, izinhlayiya nezinye izinto ze-viscous zikhangiswa ngokuqhubekayo. Ugqinsi lokufakwa kwekhabhoni luyakhula futhi umphumela wokukhuthaza ubangela izinga lokushisa elingaphezulu le-carbon deposition likhuphuke kanye namandla okubophayo ehle, okukhawulela ukungezwa kwezinhlayiya eziningi. Ngesikhathi esifanayo, ukuguquguquka kokugeleza kwegesi kubangela I-viscosity ye-carbon deposit iyanda. Uma idiphozi ye-carbon inamathele odongeni, ngaphansi kwethonya lokushisa eliphakeme lesikhathi eside, ukusabela kwamakhemikhali njengokubola, ukuphelelwa amandla kwamanzi, kanye ne-polymerization kuzokwenzeka, futhi ungqimba lwe-carbon deposit luzophinde luhlanganiswe.
