Intuthu ikhiqizwa uma kusha okuthile. Intuthu iqukethe amagesi kanye nezinhlayiya eziqinile ezilenga kuyo. Ngakho-ke intuthu iyi-aerosol. Ngenxa yokuthi intuthu ifudumele kunomoya ozungezile, intuthu iyakhuphuka uma kungekho moya oyiphushayo phansi.
Intuthu iyingozi ezilwaneni nakubantu. Ilimaza amaphaphu. Kuya ngokuthi intuthu iqhamuke kuyiphi amafutha. Intuthu yomlilo wezinkuni ayinabungozi kakhulu kunalapho ushisa ipulasitiki. Kubuye kuncike ekutheni intuthu igxile kakhulu noma ngabe umoya usuwuhlambulule kakhulu.
Intuthu ishiya ungqimba olumnyama ezindongeni zangaphakathi zikashimula, umule. Kufanele uyisuse ngezikhathi ezithile ukuze intuthu ibaleke kahle. Esikhathini esidlule, umule wawusetshenziselwa ukwenza uyinki.
Yiziphi izinhlobo zentuthu ezikhona?
Kuya ngokuthi iyiphi impahla eshisiwe. Indima ebalulekile iphinde idlalwe ukuthi ngabe bekukhona yini umoya-mpilo omningi eduze ngesikhathi kushiswa. Ngokwesibonelo, uma kunomoya-mpilo owanele, isikhutha maningi amathuba okuba sikhiqizwe kune-carbon monoxide. I-Carbon dioxide ayinabo ubuthi empeleni ngoba siyayiphefumula. Ngakolunye uhlangothi, i-carbon monoxide iyigesi enobuthi bangempela.
Ngokwesibonelo, ukhuni olumanzi, amafutha amadala, noma amafutha ampofu. Okuningi kakhulu umule nomlotha ondizayo nawo ungena emoyeni. Lokhu kwenza intuthu ibe mpunga noma ibe mnyama. Izinjini zemikhumbi, ngokwesibonelo, zivame ukusebenzisa uphethiloli ongakaze uhlanzwe. Ishibhile kodwa iza nentuthu eningi.
Okukhishwa yimoto kubizwa ngokuthi “i-exhaust gas”. Udinga leli gama ngoba cishe azikho izingxenye ezilungisiwe kulo. Ngaphezu kwamagesi ahlukahlukene, amaconsi amanzi amancane akhiqizwa ngesikhathi sokusha. Bafaka umbala omhlophe wentuthu ye-exhaust. Lokhu kugqama kakhulu uma injini isabanda.
Izimboni zinezihlungi ezingasetshenziswa ukuhlanza intuthu. Ungafinyelela impumelelo enkulu ngalokhu namuhla. Izihlungi ze-exhaust nazo zifakwe ezimotweni zikadizili. Iziguquli ze-Catalytic zisetshenziswa ezinjinini zikaphethiloli. Lezi "post-combustors" ziqinisekisa ukuthi kukhiqizwa amagesi anobuthi ambalwa. Kodwa-ke, i-carbon dioxide evela ezitshalweni zamandla aphehlwa ngamalahle ayikwazi ukuhlungwa. Kuyigesi ebamba ukushisa futhi inomthelela omkhulu ekuguqukeni kwesimo sezulu.
Ingabe intuthu ingase ibe usizo?
Ukubhema kuyindlela endala kakhulu yokugcina inyama nenhlanzi. Iphinde iguqule ukunambitheka kwalokhu kudla. Abantu abaningi bathanda lokho ngempela.
Abafuyi bezinyosi bayazi iqhinga elikhethekile lokuvimbela izinyosi ekuzilumeni: Bathulisa izilwane ezincane ngomusi. Ngaphezu kwalokho, kukhona ukuvikelwa okunikezwa izingubo zabo ezikhethekile.
Ukufuthwa kungaxosha izinambuzane. Abanye abazingeli basebenzisa intuthu ukuze baxoshe izilwane ezinjengamabheja nezimpungushe emigodini yazo ukuze bazibulale.
Izimpawu zentuthu zingasetshenziswa ukuthumela imilayezo ebangeni elide. Izizwe eziningi zaboMdabu baseMelika zasebenzisa le ndlela. Kufana kakhulu nokukhethwa kukaPapa eVatican. Uma kukhethwa upapa, kukhishwa intuthu emhlophe. Intuthu emnyama ikhomba ukuthi umhlangano awukakalungeli futhi uzophinde uqokwe.
ESontweni LamaKatolika Nama-Orthodox, kushiswa impepho ngezikhathi ezikhethekile phakathi nenkonzo. Ukuze wenze lokhu, inhlaka yezihlahla ezithile ishiswa esitsheni. Intuthu inephunga elinamandla futhi elimnandi. Abantu baseGibhithe lasendulo babesebenzisa impepho lapho abafileyo becwiliswa izidumbu. EBhayibhelini, kubhekwa njengesinye sezipho zamaKhosi Amathathu.
Abanye abantu bathanda intuthu kagwayi nemikhiqizo kagwayi ehlobene. Iphinde ikunike umuzwa omuhle isikhathi esithile. Nokho, intuthu ilimaza amaphaphu nezinye izingxenye zomzimba.
