Umsebenzi oyinhloko wokuhlanganiswa kwe-injector
Indima eyinhloko ye-injector assembly ukulawula inani le-fuel injection kanye nesikhathi se-injection ukuqinisekisa ukusebenza okuvamile kanye nokusebenza kahle kwe-injini. I-injector assembly ingalawula ngokunembile inani le-injection kaphethiloli ngokwamukela isignali ye-injection pulse evela ku-ECU (iyunithi yokulawula kagesi), ukuze ihlangabezane nezidingo zenjini ezimweni ezahlukene zokusebenza. Izici ze-spray ze-injector, kufaka phakathi usayizi wezinhlayiya ze-atomization, ukusatshalaliswa kwe-oyela spray, isiqondiso se-oyela beam, ububanzi kanye ne-diffusion cone I-Angle, njll., kufanele ihlangabezane nezidingo ze-diesel engine combustion system ukuqinisekisa ukwakheka okuphelele kanye nokushiswa kwengxube, ukuze kuthuthukiswe amandla kanye nokusebenza kahle kokushisa kwenjini.
Umgomo othize wokusebenza kanye nesimo sokusetshenziswa kwenhlangano ye-injector
Ukuhlanganiswa kwe-injector kudlala indima ebalulekile ohlelweni lokujova uphethiloli. Uhlelo lokujova uphethiloli ngokwezinhlobo ezahlukene zokujova uphethiloli, lungahlukaniswa ngohlelo lokujova uphethiloli, uhlelo lokujova uphethiloli kanye nohlelo lokujova uphethiloli wegesi. Ngokwezindlela ezahlukene zokulawula, lungahlukaniswa ngohlobo lokulawula okwenziwa ngomshini, uhlobo lokulawula ngogesi kanye nohlobo lokulawula oluhlanganisiwe lwe-electromechanical. Ukuhlanganiswa kwe-injector kaphethiloli ngokusebenzisa ingcindezi ethile ukufaka uphethiloli ngqo ku-cylinder noma ku-inlet, ukuze kufezwe ukunikezwa kukaphethiloli okunembile. Ikakhulukazi ezinjinini zedizili, ukunemba kwe-injector kuhlangana kuthinta ngqo amandla kanye nokonga kwenjini yedizili, ngakho-ke ukunemba kwayo kokucubungula kanye nezidingo zokusebenza ziphezulu kakhulu. Ukuhlanganiswa kwe-injector kuyingxenye ebalulekile yesistimu kaphethiloli wedizili, esetshenziselwa ukulawula ngokunembile inani lokujova uphethiloli kanye nesikhathi sokujova. Ukuhlanganiswa kwe-injector kaphethiloli kuqukethe izingxenye eziningi, kufaka phakathi ingxenye yokuphakelwa kaphethiloli, ingxenye yokuphakelwa kwegesi kanye nengxenye yokulawula. Umgomo wayo osebenzayo ukulawula ukufakwa kukaphethiloli nge-solenoid valve noma uhlelo lwe-hydraulic servo ukuqinisekisa ukuthi uphethiloli ufakwa ngokunembile ekamelweni lokushiswa ngaphansi komfutho ophezulu. Izici zokufafaza ze-injector, njengosayizi wezinhlayiya ze-atomization kanye nokusatshalaliswa kwe-oyili inkungu, zinomthelela obalulekile ekusebenzeni kwamandla kanye nokonga kwenjini kadizili.
Ukwakheka kanye nomgomo wokusebenza kwenhlangano ye-injector
I-injector assembly yakhiwe kakhulu yingxenye yokuphakelwa kukawoyela, ingxenye yokuphakelwa kukaphethiloli kanye nengxenye yokulawula. Ingxenye yokuphakelwa kukawoyela ihlanganisa ithangi likawoyela, iphampu kaphethiloli, isihlungi sikaphethiloli, isilawuli sokucindezela kanye ne-injector kaphethiloli. Isimiso esisebenzayo ukuthi uphethiloli ukhishwa ethangini likawoyela ngephampu kaphethiloli, uhlungwe yisihlungi, bese ucindezelwa yisilawuli sokucindezela, bese ekugcineni uthunyelwa ku-injector yesilinda ngasinye. Ingxenye yokulawula ilawula ngokunembile inani nesikhathi sokuphakelwa kukaphethiloli nge-solenoid valve noma uhlelo lwe-hydraulic servo.
Uhlobo kanye nokusetshenziswa kwenhlangano ye-injector
Ama-fuel injector assemblies atholakala ngezinhlobo ezahlukene, kufaka phakathi ama-hole injectors, ama-needle injectors kanye nama-low inertia injectors. I-hole injector ifanelekela injini yedizili yegumbi lokushisa eliqondile, kanti i-shaft needle injector inezinzuzo zobubanzi obukhulu bembobo, ingcindezi ephansi ye-fuel injection, futhi imbobo akulula ukuyiqoqa i-carbon blockage. Lezi zinhlobo ezahlukene zama-fuel injectors zingahlangabezana nezidingo zezinjini ezahlukene zedizili ngokuya ngezakhiwo zazo ezahlukene kanye nezimo zokusetshenziswa.
