Binciken lambobi da nazarin gwaji akan injector dizal na solenoid gama gari tare da bawul ɗin sarrafawa(Kashi na 1)

Abstract.

An ƙirƙira ƙirar lissafi na injector man dogo na solenoid gama gari.Bambancinsa daga samfuran da ake dasu shine sarrafa bawul lalacewa simulation.Injector na gama gari na 0445110376 Series (Cummins ISf 2.8 Diesel engine) wanda Kamfanin Bosch ya samar an yi amfani da shi azaman abin bincike.An ƙaddara sigogin allura (bayar da man fetur da zubewar baya) ta hanyar lissafi da hanyoyin gwaji.Matsakaicin ƙirar GT-Suite R2 shine 0.93 wanda ke nufin yana tsinkayar sifar adadin allura daidai sosai (sharuɗɗan fasaha na ƙima da ƙima na injector).Binciken ƙididdiga da gwaje-gwaje na gwaji sun nuna cewa lalacewa na bawul ɗin sarrafawa yana ƙaruwa da baya da kuma isar da man fetur (musamman a 160 MPa).An ɓullo da samfuran koma baya don tantance isar da man fetur da tasirin ɗigogi na baya akan matsin man fetur da lokacin kuzari (don yanayin fasaha na ƙima da ƙima).
