I-valve ye-EGR (i-valve yokubuyisela i-exhaust gas) iwumkhiqizo we-mechatronic ofakwe enjinini yedizili ukulawula inani lokubuyisela i-exhaust gas ohlelweni lokungenisa.
I-valve ye-EGR iwumkhiqizo we-mechatronic ofakwe enjinini kadizili ukulawula inani lokujikeleza kabusha kwegesi yokukhipha elidluliselwa ohlelweni lokungenisa. Ngokuvamile itholakala ohlangothini lwesokudla lwe-manifold yokungenisa, eduze komzimba we-throttle, futhi ixhunywe kuyo ngethubhu yensimbi emfushane eholela ku-manifold yokukhipha. Umsebenzi wayo ukulawula inani legesi yokukhipha engena ku-manifold yokungenisa, ukuze inani elithile legesi yokukhipha ligeleze ku-manifold yokungenisa ukuze liphinde lijikeleze. I-valve ye-EGR iyingxenye ebaluleke kakhulu futhi ebaluleke kakhulu kudivayisi yokujikeleza kabusha kwegesi yokukhipha.
I-valve ye-EGR ihlukaniswe izinhlobo ezimbili: uhlobo lomshini kanye nohlobo lokulawula lwe-elekthronikhi.
I-valve ye-EGR yehlisa izinga lokushisa legumbi lokusha ngokuqondisa igesi yokukhipha ephuma ekushiseni kwenjini iye kwi-intake manifold ukuze ihlanganyele ekushiseni, ithuthukise ukusebenza kahle kwenjini, ithuthukise indawo yokusha, futhi inciphise umthwalo enjinini, inciphise ngempumelelo ukukhishwa kwama-NO compounds, inciphise ukungqongqoza, futhi yandise isikhathi senkonzo yengxenye ngayinye.
Igama eligcwele yi-Exhaust Gas Recirculation, okungukuthi, i-exhaust gas recirculation [1] Uhlelo lusetshenziselwa ukunciphisa ukukhishwa kwama-nitrogen oxides (NOX) kugesi yokukhipha umoya. I-nitrogen ne-oxygen zisabela ngamakhemikhali kuphela ngaphansi kwezimo zokushisa okuphezulu kanye nokucindezela okuphezulu, kanti izinga lokushisa kanye nokucindezela ekamelweni lokushisa lenjini kuhlangabezana nalezi zimo, ikakhulukazi ngesikhathi sokusheshisa okuphoqelelwe. Lapho injini isebenza ngaphansi komthwalo, i-valve ye-EGR iyavuleka, ivumela inani elincane legesi yokukhipha umoya ukuthi lingene ku-intake manifold futhi lingene ekamelweni lokushisa kanye nengxube evuthayo. I-valve ye-EGR ivaliwe lapho ingasebenzi, futhi igesi encane yokukhipha umoya ijikeleziswa enjinini. Igesi yokukhipha umoya yemoto iyigesi engashisi (engenawo uphethiloli kanye ne-oxidant) engahlanganyeli ekushiseni ekamelweni lokushisa. Inciphisa izinga lokushisa kanye nokucindezela kokushisa ngokumunca ingxenye yokushisa okukhiqizwa ukushisa ukuze kuncishiswe ukukhiqizwa kwama-nitrogen oxides. Inani legesi yokukhipha umoya engena ekamelweni lokushisa liyanda ngesivinini senjini kanye nomthwalo.
Ukujikeleza kabusha kwegesi yokukhipha umoya kuyindlela lapho ingxenye yegesi yokukhipha umoya ifakwa khona emoyeni omusha ophefumulayo (noma ingxube) ngesikhathi senqubo yokusebenza kwenjini, bese ibuyiselwa kwisilinda ukuze iphinde ijikelezwe ukuze ihlanganyele ekushiseni. Umsebenzi wayo ukunciphisa ukukhishwa kwe-NOx. I-NOx iyigesi eyingozi kakhulu emzimbeni womuntu, ekhiqizwa kakhulu ngaphansi kwezimo zokushisa okuphezulu nezinomoya-mpilo omningi. Ngesikhathi senqubo yokusebenza kwenjini, uma ingxenye yegesi yokukhipha umoya ibuyiselwa kwisilinda ngesikhathi esifanele nangendlela efanele, ngoba ingxenye eyinhloko yegesi yokukhipha umoya inamandla okushisa athile, i-CO2, igesi yokukhipha umoya ingamunca ingxenye yokushisa okukhiqizwa ukushisa bese iyikhipha kwisilinda, futhi inomphumela omuhle engxubeni. Umphumela othile wokuxuba, ngaleyo ndlela kunciphisa izinga lokushisa eliphezulu kanye nokuqukethwe komoya-mpilo kokushiswa kwenjini, ngaleyo ndlela kunciphisa ukwakheka kwamakhemikhali e-NOx.
Kodwa-ke, ukujikeleza ngokweqile kwegesi yokukhipha kuzothinta ukusebenza okuvamile kwenjini, ikakhulukazi lapho injini isebenza ngesivinini esingasebenzi, isivinini esiphansi kanye nomthwalo ophansi futhi injini isebenza esimweni sokubanda, futhi lapho amandla enjini edingeka ngomthwalo ogcwele (i-throttle egcwele), ukujikeleza kabusha kwegesi Igesi yokukhipha igesi izoba nomthelela omkhulu ekusebenzeni kwenjini. Ngakho-ke, inani legesi yokukhipha igesi ehlanganyela ekujikelezeni kabusha kufanele lilungiswe ngokuzenzakalelayo ngokuya ngezimo zokusebenza zangempela zenjini kanye nezinguquko ezimweni zokusebenza. Umkhuba ukhombisile ukuthi, ngokwezakhiwo ezahlukene zenjini, inani legesi yokukhipha igesi ehilelekile ekujikelezeni kabusha ngokuvamile lihluka phakathi kuka-6% no-13%.
Ukuze inani lokujikeleza kabusha kwegesi yokukhipha lingabi nomthelela omkhulu ekusebenzeni kwenjini, izinjini zesimanje ezilawulwa ngogesi nazo zisebenzisa isu lokulawula i-closed-loop lokujikeleza kabusha kwegesi yokukhipha, futhi inzwa yesikhundla se-valve ye-EGR ifakiwe ku-valve yokujikeleza kabusha kwegesi yokukhipha (amanye amamodeli asebenzisa nezinzwa zokushisa kwegesi yokukhipha). noma inzwa yokucindezela), ukulawulwa kwempendulo yokulungisa i-closed-loop yenani langempela lokujikeleza kabusha kwegesi yokukhipha kwenziwa. Isikhala sokuhamba ngebhizinisi. Ukuphakama kwephansi ukusuka phansi kuphansi, futhi izinga lokusetshenziswa kwesikhala sangaphakathi liphezulu kakhulu phakathi kwemikhiqizo efanayo, okuphakeme ngo-19% kuneyemikhiqizo efanayo; isikhala esikhulu.

Ukulawula okuhlakaniphile
I-6AMT manual transmission, igiya elihlanganisiwe lokulawula eliphakathi, lingakhetha izinhlobo ezahlukene ze-6MT, 6AMT transmission, igiya lithambile futhi libushelelezi, futhi ukulawula kulula kakhulu.
Ukulungiswa kwe-chassis yobungcweti ye-MIRA okuqinile nokusezingeni eliphezulu kunikeza umuzwa wokushayela ofana nowemoto yomgibeli. Ubuchwepheshe bokumiswa komoya bungathuthukisa kakhulu ikhono lokuhlukanisa ukudlidliza komgwaqo, futhi buthuthukise ngokuphelele umkhawulo wokulawula kanye nenduduzo [19]
Ithembekile futhi ihlala isikhathi eside
Ishidi lensimbi elikhethekile elinohlangothi oluphindwe kabili, upende oncibilika emanzini olunobungani nemvelo lwe-EPP, izinqubo ezine zokwelashwa ngopende ze-phosphating, i-electrophoresis, i-middle coating kanye ne-topcoat ukuqinisekisa ukuthi ngeke ibole iminyaka eyi-10. (Indinganiso kazwelonke idinga iminyaka eyi-7)
