Iyini i-nozzle kaphethiloli yeketanga lesikhathi semoto
I-nozzle ye-automotive timing chain iyisici esibalulekile sohlelo lokuhlinzeka ngophethiloli wenjini. Umsebenzi wayo oyinhloko ukufutha uphethiloli olinganiswe kahle egumbini lokushiswa kwenjini ngesimo senkungu ukuqinisekisa ukuthi uphethiloli ungashiswa ngokuphelele, ngaleyo ndlela kuthuthukiswe ukusebenza kahle nokusebenza kwenjini.
Isimiso sokusebenza
I-nozzle yokujova uphethiloli iyi-solenoid valve. Lapho iyunithi yokulawula kagesi (i-ECU) ithumela imiyalelo, ugesi udlula kukhoyili e-nozzle yokujova uphethiloli, ukhiqize insimu kagesi, uqhube i-valve ye-fuel injector ukuthi ivuleke, bese uphethiloli ufafazwa usuka emgodini wokujova uphethiloli ngesivinini esikhulu ukuze kwakheke inkungu, evumela ukusha okugcwele .
Izici zesakhiwo
I-nozzle ivame ukwakhiwa yi-solenoid coil, inaliti ye-valve, kanye nembobo yokufutha. Uma i-solenoid coil inikwe amandla, inaliti ye-valve iyamuncwa bese imbobo yokufutha iyavulwa. Uphethiloli ufuthwa ngesivinini esikhulu ngesikhala esiphakathi kwenaliti ye-shaft kanye nembobo yokufutha, kwakha inkungu.
Isiphakamiso sokulungisa
Ukugcinwa kwe-nozzle yokujova uphethiloli kubaluleke kakhulu, ngoba isimo sayo sokusebenza sithinta ngqo ukusebenza kwenjini. Ukuhlanza njalo i-nozzle kungavimbela ukuqongelela kwekhabhoni kanye nokungcola ekuvimbeleni i-nozzle, kuqinisekiswe ukunemba kokuhlinzekwa kukaphethiloli kanye nokusebenza okuvamile kwenjini. Ngokuvamile kunconywa ukuhlanza i-nozzle kaphethiloli njalo ngokwesimo semoto kanye nekhwalithi kaphethiloli, futhi ngokuvamile kunconywa ukuhlanza kanye njalo ngamakhilomitha angu-20,000 .
Umsebenzi oyinhloko we-nozzle yesikhathi semoto ukuxhumanisa isikhathi sokusha kwe-valve ukuqinisekisa ukuthi uphethiloli ungafakwa ku-cylinder njalo nangobuningi, ukuze kuthuthukiswe ukusebenza kahle kokushisa. Ngokuqondile, i-nozzle ye-fuel injection ilawula ukusha kwe-fuel nge-solenoid valve, ukuze uphethiloli ufafazwe enkungwini, okuhambisana nokuxubana okuphelele kukaphethiloli nomoya, kuthuthukiswe ukusebenza kahle kokushisa, futhi ngaleyo ndlela kuthuthukiswe ukusebenza kwamandla kwemoto .
Umgomo wokusebenza kwe-nozzle kawoyela
I-nozzle iyidivayisi ye-solenoid valve, lapho i-solenoid coil inikwe amandla, izokhipha ukumunca ukuvula i-nozzle, ukuze uphethiloli ufafazwe enkungwini. Ingaphinde ithole isignali yokushaya kwe-fuel injection yeyunithi yokulawula kagesi yenjini, futhi ilawule ngokunembile inani le-fuel injection kanye nesikhathi se-fuel injection. Ukusebenza kwe-atomization kanye nekhono lokulwa nokuvaleka kwe-nozzle kubalulekile ekusebenzeni kwayo.
Izinhlobo ezahlukene zama-fuel injector kanye nezici zazo
Umjovo we-incase manifold : Uphethiloli ufakwa ku-incase manifold bese ungena enjinini nge-valve. Inzuzo yale ndlela ukuthi i-valve ihlanzekile, ibanga lokusha lide, futhi akulula ukukhiqiza idiphozithi yekhabhoni, kodwa umjovo we-oyela awunembile ngokwanele, okungaholela ekusetshenzisweni kukaphethiloli okwandisiwe kanye namandla anganele .
Umjovo oqondile wesilinda : umjovo oqondile wesilinda, umjovo unembile kakhulu, ungathuthukisa ukusetshenziswa kukaphethiloli, unciphise ukusetshenziswa kukaphethiloli, uthuthukise amandla, kodwa izidingo zekhwalithi kaphethiloli ziphakeme, ingcindezi yomugqa kaphethiloli nayo iphakeme.
Isiphakamiso sokulungisa
Ukuze kuqinisekiswe ukusebenza okuvamile kwe-nozzle, kunconywa ukuhlola nokuhlanza i-nozzle njalo ukuze kugwenywe ukuvaleka nokungcola. Ngaphezu kwalokho, ngokwendlela okusetshenziswa ngayo imoto kanye nezincomo zomenzi, shintsha njalo i-timing chain kanye ne-fuel nozzle ukuze ugcine ukusebenza okuhle kakhulu kwenjini.
