Imfihlo Yezinjini Ze-Turbo Ezimotweni
Kulesi sikhathi sanamuhla, ubuchwepheshe bezimoto buthuthuke ngokushesha, buhlinzeka ngezinto ezintsha ezahlukahlukene ezenza izimoto zisebenze kahle, zibe namandla, futhi zibe nobungane nemvelo. Ubuchwepheshe obunye obushintshe imboni yezimoto yi-turbocharger, noma injini ye-turbo. Lobu buchwepheshe buvumela izimoto ukuthi zikhiqize amandla amakhulu ngaphandle kokwandisa amandla enjini, okwenza zibe namandla futhi zisebenze kahle. Lesi sihloko sizohlola ngokujulile izimfihlo zezinjini ze-turbo ezimotweni, indlela ezisebenza ngayo, izinzuzo zazo, ukubi kwazo, kanye nentuthuko yesikhathi esizayo.
Iyini Injini Ye-Turbo?
I-turbocharger, eyaziwa kakhulu ngokuthi i-turbo, iyithuluzi elisetshenziselwa ukwandisa ukusebenza kahle kanye namandla enjini yokushisa yangaphakathi. I-turbocharger isebenza ngokusebenzisa amagesi okukhipha umoya avela enjinini ukuze ijikeleze i-turbine exhunywe kwi-compressor. Le compressor ibe isicindezela umoya ongena ekamelweni lokushisa. Lo moya oqinile uvumela umoya-mpilo owengeziwe ukuthi ungene ekamelweni lokushisa, okuvumela ukushisa okusebenzayo kanye nokukhishwa kwamandla okukhulu.
Indlela Injini Ye-Turbo Esebenza Ngayo
I-turbocharger inezingxenye ezimbili eziyinhloko: i-turbine kanye ne-compressor. Amagesi okukhipha umoya avela enjinini angena endlini ye-turbine, aphendule ama-blade e-turbine. I-turbine ixhunywe ku-shaft exhunywe ne-compressor ngakolunye uhlangothi. Njengoba i-turbine ijikeleza, i-compressor nayo iyajikeleza, idonsa umoya usuka ngaphandle, iwucindezele, bese ithumela lo moya onomfutho ophezulu enjinini.
Lo mjikelezo wandisa inani lomoya ongena ekamelweni lokushisa. Uma umoya omningi ungena, uphethiloli omningi ungashiswa, kukhiqizwe amandla amakhulu ngaphandle kokwandisa ukufuduka kwenjini. Lesi yisihluthulelo sokuthi kungani izinjini ezine-turbocharger zingakhiqiza amandla amakhulu ngokusebenza kahle okukhulu.
Izinzuzo Zezinjini Ze-Turbo
1. Amandla Akhuphukile
Inzuzo esobala kakhulu yenjini ene-turbocharger amandla ayo akhuphukile. Izinjini ezine-turbocharger zivumela izimoto ezincane ukuthi zikhiqize amandla afanayo nezinjini ezinkulu, okuletha ukusebenza okuhle kakhulu.
2. Ukusetshenziswa Kahle Kaphethiloli
Izinjini ezine-turbocharger zingashisa uphethiloli ngendlela ephumelela kakhulu ngoba umoya ocindezelwe uqukethe umoya-mpilo owengeziwe, osekela ukusha okuphumelelayo kakhulu. Ngenxa yalokho, kudingeka uphethiloli omncane ukuze kukhiqizwe amandla afanayo.
3. Ayinandaba nemvelo
Ukusebenza kahle kakhulu kusho ukukhishwa okuphansi komoya ongcolile. Izinjini ezine-turbocharger zinganciphisa ukukhishwa kwegesi ebamba ukushisa ngenxa yokushisa okuphelele nokuphumelelayo. Ezimweni eziningi, lezi zinjini zihlonyiswe nobuchwepheshe obengeziwe njenge-catalytic converters ukuze kuncishiswe umthelela emvelweni.
4. Desain Kompak
Izinjini ezine-turbocharger zivumela izinjini ezincane, kodwa ezisanamandla. Lokhu kuvumela abenzi bezimoto ukuthi baklame izimoto ezilula nezisebenza kahle ngaphandle kokunciphisa ukusebenza kahle.
Izinkinga Zezinjini Ze-Turbo
1. Ubunzima kanye Nezindleko
Izinjini ezine-turbocharger ziyinkimbinkimbi kakhulu kunezinjini ezingenayo i-turbocharger ngoba zakhiwe izingxenye eziningi ezisebenza ngokucindezela okukhulu kanye namazinga okushisa aphezulu. Lokhu kuphumela ezindleleni zokukhiqiza eziphezulu, ukugcinwa, kanye nokulungisa. Ngaphezu kwalokho, umonakalo wezingxenye ezine-turbocharger kungaba yinkinga enkulu futhi ebiza kakhulu ukuyilungisa.
2. I-Turbo Lag
Inkinga eyodwa evame ukuhlotshaniswa nezinjini ze-turbo yinto ebizwa ngokuthi "i-turbo lag." Lokhu ukubambezeleka phakathi kwesikhathi lapho umshayeli ecindezela khona i-accelerator pedal kanye nesikhathi lapho i-turbo iqala ukukhiqiza amandla akhuphukile. I-Turbo lag yenzeka ngoba i-turbine idinga isikhathi ukuze ifinyelele isivinini esanele ukuze icindezele umoya.
3. Izidingo Eziphezulu Zokugcoba
Izinjini ze-turbo zisebenza ngokucindezela okukhulu kakhulu kanye namazinga okushisa, okudinga ukugcotshwa okuthuthukisiwe. Lokhu kudinga abanikazi bezimoto ukuthi bashintshe uwoyela kaningi futhi basebenzise uwoyela osezingeni eliphezulu ukuqinisekisa ukuthi i-turbo ihlala isikhathi eside futhi isebenza kahle.
Ukuthuthukiswa Kwezinjini Ze-Turbo Esikhathini Esizayo
Ukusungula izinto ezintsha kanye nentuthuko kwezobuchwepheshe kuyaqhubeka nokuthuthukisa izinjini ezine-turbocharger. Enye yezindlela zakamuva ukusetshenziswa kwama-turbocharger e-twin-scroll kanye nama-turbocharger e-variable-geometry (VGTs). Lobu buchwepheshe buhlose ukunciphisa i-turbo lag nokwandisa ukusebenza kahle kanye nokuphendula kohlelo lwe-turbocharger.
I-Turbo Ehamba Ngambili Eskrola
I-turbo enama-twin-scroll isebenzisa izindlela ezimbili ezihlukene zegesi yokukhipha umoya ukuze ijikeleze i-turbine. Lokhu kuthuthukiswa kuvumela i-turbo ukuthi iphendule ngokushesha ngoba enye indlela ingajikeleza i-turbine ngesivinini esiphansi senjini, kanti enye indlela isebenza ngesivinini esikhulu senjini. Lokhu kusiza ukunciphisa ukubambezeleka kwe-turbo futhi kwandisa ukusebenza kahle ebangeni elibanzi lesivinini senjini.
I-Turbocharger yeJiyomethri Eguquguqukayo (VGT)
I-VGT ivumela i-engeli ye-turbine blade ukuthi ishintshe kuye ngesivinini senjini. Ngesivinini esiphansi, ama-turbine blade ayavalwa ukuze kwandiswe isivinini sokugeleza kwegesi ephumayo, kanti ngesivinini esiphezulu, ayavulwa ukuze kuncishiswe ukudonswa. Lobu buchwepheshe buthuthukisa ukusebenza kahle kwe-turbo kanye nokuphendula ngaphansi kwezimo ezahlukahlukene zokushayela.
Injini Kagesi ene-Turbo
Njengoba izimoto zikagesi zithandwa kakhulu, abakhiqizi bezimoto abaningana sebeqalile ukwakha ama-turbocharger kagesi. Lolu hlobo lwe-turbo lusebenzisa injini kagesi ukushayela i-compressor, okuqeda isidingo segesi yokukhipha ugesi njengomthombo wamandla. Ngenxa yalokho, i-turbo inganikeza amandla asheshayo ngaphandle kokubambezeleka kwe-turbo.
Isiphetho
Izinjini ezine-turbocharger zishintshe indlela esibheka futhi sishayela ngayo izimoto. Njengoba zinamandla okwandisa amandla nokusebenza kahle kukaphethiloli, ngenkathi zinciphisa ukukhishwa kwegesi, lobu buchwepheshe buhlinzeke ngezinzuzo ezibalulekile hhayi kubashayeli kuphela kodwa nakwezemvelo. Naphezu kwezinye izinkinga, njengokulibaziseka kwe-turbo kanye nobunzima, ukusungula izinto ezintsha kanye nocwaningo kuyaqhubeka nokubhekana nalezi zinselele futhi kuthuthukiswe kakhulu izinjini ezine-turbocharger.
Njengoba siqhubeka nokuthuthuka kobuchwepheshe, singalindela ukuthi ama-turbocharger asebenze kahle kakhulu, athembeke kakhudlwana, futhi abe nobungane nemvelo. Phakathi kokukhathazeka okukhula ngokushintsha kwesimo sezulu kanye nemithombo yamandla elinganiselwe, ama-turbocharger azoqhubeka nokudlala indima ebalulekile ekwakhiweni nasekuthuthukisweni kwezimoto zesikhathi esizayo. Ngawo wonke amandla azo, ama-turbocharger awawona nje umkhuba wezobuchwepheshe, kodwa ayisici esibalulekile ekuthuthukisweni kwezimoto ezihlakaniphile, ezisebenza kahle kakhulu, nezisimeme kakhudlwana.
