I-Diesel Injector Fuel Injector 095000-6383 Denso Injector ye-Komatsu Excavator

Ngokuthuthuka okusheshayo kwenjini yezimoto zikadizili, inkinga yokuphuma kwenjini kadizili idonse ukunaka okukhulu, futhi izwe selimemezele imithetho nemithethonqubo eqinile yokukhipha umoya.Nakuba okwamanje kunezinjini eziningi zikadizili eziqala ukusebenzisa i-high pressure common rail system ukuze kuncishiswe ukusetshenziswa kukaphethiloli nokunciphisa ukukhishwa kwegesi, kodwa esimweni sethu samanje, ipompo yokujova kaphethiloli eyimishini isathandwa ngabasebenzisi abaningi ngenxa yentengo yayo eshibhile, ukuthembeka okuhle, elula. ukugcinwa kanye nezinye izinzuzo... .Njengamanje, ubunzima obukhulu bokulawula ukukhishwa kwenjini yedizili buku CHA;Futhi izinhlayiya (PM), ukungcola okubili kuphambene komunye nomunye ngokwemibandela yokwakheka, futhi akunakwenzeka ukusebenzisa indlela eyodwa yobuchwepheshe ukuze kuzuzwe ukulawulwa kanyekanye kwalezi zinto ezimbili ezingcolisayo.CHA, igama elivamile lama-oxide ahlukahlukene e-nitrogen ngesikhathi sokusha, okuhlanganisa NO, NO:, N: 0. Njll. Inombolo ka-CHA inkulu kakhulu, futhi izinga lokukhiqiza lika-CHA enqubweni yokuvutha lincike kakhulu ekushiseni kokushisa. .Ngaphezu kwalokho, ukuhlushwa komoya-mpilo, ikakhulukazi ukuhlushwa kwe-oxygen ye-athomu endaweni evuthayo, kunomthelela omkhulu ku-NO.Izinga lokukhiqiza libaluleke kakhulu.Ngaphezu kwalokho, ukusabela kwamakhemikhali nakho kuthatha isikhathi, i-nitrogen ne-oxygen ngesikhathi sokugcina izinga lokushisa eliphezulu ngu-NO.Izinga lokukhiqiza lingesinye isici esibalulekile.Izinga lokushisa eliphezulu, ukunothisa komoyampilo kanye nesikhathi sokugcinwa kwe-oxygen ne-nitrogen ekushiseni okuphezulu kunquma CHA enqubweni yokuvutha kwenjini yedizili.Izinto ezintathu zosayizi wesivuno.I-PM yenziwe nge-soot eyomile, izakhi eziphilayo ezincibilikayo, ezingancishiswa ngokunciphisa okuqukethwe kwesulfure ye-diesel, nama-sulfate.Izingxenye ze-organic ezincibilikayo zingama-hydrocarbon asindayo, angasuswa yizisusa ze-oxidation, ngakho-ke ukunciphisa ukukhishwa kwezinhlayiyana kugxile ekwehliseni ukwakheka komle owomile 1. Ukuze kwehliswe inani lokukhishwa kwe-NO, i-Angle yokuphakelayo emile idinga ukulibaziseka, kodwa izokwandisa intuthu kanye PM.Lokhu kudinga ukukhethwa komjovo olungile, indawo yokufaka i-injector, ukuthuthukiswa kokugeleza komfutho ophezulu, ukunciphisa isikhathi sokubambezeleka kokusha, thola i-Angle elungile yokunikezwa kukaphethiloli emile, qedela u-NO.Futhi inani le-PM lehla ngesikhathi esifanayo, ukuze izinga lokukhishwa kwenjini kadizili lihlangabezane nezweⅢemission standard.
