New Injector Nozzle Dlla157p1424 0433171886 OE Me 226718 Me222914 for Fuel Injector 0445120048

1. Mugero wakakodzera wevaviri vetsono valve unowanzo 2 ~ 4μm. Tichifunga nezveiyo chaiyo yekugadzirisa nhanho, iyo gap yakakodzera ndeye 1 ~ 10μm mukutsvagisa, kureba kweiyo tsono yevharuvhu yekuvharisa inosvika 8.4mm, eccentricity chiyero chevharuvhu yetsono i zero, uye chiyero chekurerekera i zero. , isa iyo inlet port pressure kusvika 120MPa, tevedzera uye uverenge chiyero chekudonha kwemafuta mugomba retsono valve coupler pasi pemafuta akasiyana firimu makubvu, sezvo ukobvu hwefirimu remafuta hunowedzera, chiyero chekuvuza chevhavhavhavha yetsono inowedzera, uye iyo leakage rate gradient inowedzera. Kana kukora kwefirimu kuri 1μm, chiyero chekuvuza chiri 0.025mL/s, uye kana ukobvu hwemufirimu hwava 10μm, chiyero chekudonha i6.37mL/s, kuwedzera kanoda kuita makumi maviri neshanu. Kana iyo firimu yemafuta yakatetepa, chiyero chekuvuza chinoshanduka mujika neukobvu hwefirimu, uye kana iyo firimu remafuta yadarika 6 μm, chiyero chekuvuza chinoshanduka chakada kufanana nekukora kwefirimu.

2. Kureba kwechisimbiso chepamusoro ndiyo inokosha parameter yechisimbiso chevhavhavha yetsono. Muchiono, kana kureba kwevharuvhu yetsono kuchiita kunge kusingagumi, kubuda kwayo pasi pemamiriro e static i zero nekuda kwekukwenya kwe viscous kwemadziro. Mukuita, nekuda kwezvido zvekugadzira zvekugadzirisa kugadzirwa kwejekiseni, kureba kwekuvhara kwevhavha yetsono kunogumira. Pasi pehurefu hwakasiyana hwevharuvhu yekuvharisa pamusoro, hunhu hwekuisa chisimbiso hwevaviri vetsono, sezvo kureba kwevharuvhu yetsono kunowedzera, chiyero chekudonha chinodzikira nekukurumidza, uye chiyero chekuvuza chinodzikira zvakare.
