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 njengamanje kunezinjini eziningi zikadizili eziqala ukusebenzisa i-high pressure common rail system ukuze kuncishiswe ukusetshenziswa kukaphethiloli futhi kuncishiswe ukukhishwa kwegesi, kodwa esimweni sethu samanje, ipompo yomjovo kaphethiloli ongumshini isathandwa ngabasebenzisi abaningi ngenxa yentengo yayo eshibhile, ukwethembeka okuhle, elula. ukugcinwa kanye nezinye izinzuzo... . Njengamanje, ubunzima obukhulu bokulawula ukungcola kwenjini yedizili ilele kokuthi CHA; Futhi izinhlayiya (PM), ukungcola okubili kuphambene komunye nomunye ngokwemibandela yokubunjwa, futhi akunakwenzeka ukusebenzisa indlela eyodwa yobuchwepheshe ukuze kuzuzwe ukulawulwa ngesikhathi esisodwa kwalezi zinto ezimbili ezingcolile. 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-oksijini ne-nitrogen ezingeni lokushisa eliphezulu sinquma CHA enqubweni yokuvutha kwenjini kadizili. 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.
