I-Genuine New Cat Perkins Diesel Fuel Injector 2645A743 321-0990 10r-7668 Ihambisana nePerkins Pj Engine

Umthelela wobubanzi be-nozzle, ingcindezi yomjovo kanye nezinga lokushisa elizungezile ezicini zokufutha enjinini kadizili(ingxenye 3)

3. Umphumela nengxoxo

Lokhu kuhlaziya kusebenzise amadayamitha amabili ahlukene okungu-0.20 mm no-0.12 mm. Lokhu kulingisa kusetshenziswa amazinga okushisa amaningana ahlukene ku-500 K naku-700 K kuyo yonke ingcindezi yomjovo ilingisa ngo-40 MPa, 70 MPa kanye no-140 MPa. Inhloso yalokhu kulingisa iwukuphenya uhlobo oluhlukile lwesici sokufutha esithonya ububanzi bomlomo wombhobho, izinga lokushisa elizungezile kanye nomfutho womjovo wenjini kadizili. Ukuhlaziywa kwesici sesifutho salokhu kulingisa kugxile kakhulu kububanzi beconsi, ubude bokungena nobude bokuhlukana okuthonya kusukela ekusetshenzisweni kwepharamitha. Ukuzwela kwegridi kuhlolwe kumodeli enosayizi begridi abahlukene. Usayizi wegridi uhlukaniswe ngamaleveli amathathu okungamagridi amaholoholo, aphakathi nendawo namacici. Ithebula lesi-2 libonisa inani lezakhi namanodi eqembu ngalinye lamasayizi amagridi ahlukene.

Ngaphandle kwalokho, inani lezinto lisuka ku-24997 liye ku-114555 izakhi. Inani lezinto ngokusobala lilingana ngokuqondile nezinombolo zamanodi ngokukhuphuka izinga losayizi wegridi ukusuka kokumahhadla kuya kokucolile kanye nezinga lokushelela ukusuka phansi ukuya phezulu.

Ububanzi beconsi lesifutho bekunguMfanekiso 6 ubonisa ukuthi ku-40 MPa ububanzi beconsi ku-0.20 mm kanye nepharamitha engu-500 K ibonisa umbala obomvu owengeziwe umelela ithonsi losayizi omkhulu uma kuqhathaniswa no-0.12 mm 700 K. Usayizi wokusabalalisa wamaconsi ongu-0.12 mm kanye no-0.2 mm akhonjisiwe kuMfanekiso 7 no-8. Njengoba kubonisiwe emagrafu, abonisa ukuthi iphethini ye usayizi wokusabalalisa we-droplet uhambisana nomunye nomunye. Ukuphakama kwezinga lokushisa elizungezile nokucindezela komjovo kunikeza ububanzi obuncane beconsi.

Umphumela uchaza ukuthi uphethiloli ofakwe kancane ekamelweni ungabangela ukusha okuphansi. Ngesikhathi esifanayo ububanzi be-droplet buncike ekudonsweni kwe-aerodynamic ekamelweni kungase kuthinte ububanzi be-droplet okwenziwa kancane lapho umoya ushayisana nophethiloli.
