Ingabe kufanele uthenge imoto kadizili noma kaphethiloli?

Njengoba kugcwele amahlazo ngodizili phakathi kwabakhiqizi, wazi kanjani ukuthi kusafanele uthenge udizili?

Sekunesikhathi eside kunuka phu udizili, kodwa njengoba iVolkswagen ihlanyisa namadolobha amakhulu ase-Europe asecabanga ukuyivala, kubukeka sengathi iwumthombo kaphethiloli obaluleke kakhulu kunakuqala. Ngakho-ke, kufanele uyithenge?

Ezinyangeni eziningi ezedlule, udizili wawusetshenziswa kakhulu emishinini yezolimo kanye namaloli ahamba isikhathi eside, futhi intengo ngelitha yayixhaswe ngabahlinzeki bemikhiqizo yezolimo.

Ikakhulukazi, ukufika kwe-turbocharging kwaholela ekusetshenzisweni kwezinjini zikadizili ezimotweni zabagibeli, futhi sezidume kakhulu iminyaka eminingi eYurophu, lapho udizili uvame ukushibhile kunophethiloli.

Idizili ayiguquguquki kancane kunophethiloli ngakho-ke idinga isilinganiso esiphezulu sokuminyanisa nezinto zokushisisa ezikhethekile endaweni evuthayo ukuze kuqalwe ukubanda kwenzeke. Nokho, lapho isiqalile injini kadizili iyonga ngokwedlulele, idla uphethiloli ongaphansi ngamaphesenti angu-30 kunenjini eqhathaniswa nayo. uphethiloli.

Njengoba amanani kadizili njengamanje eguquguquka cishe ngezinga elifanayo nelikaphethiloli ovamile ongafakwanga, lokhu kuwenza akhange, ikakhulukazi uma uqhathanisa nezimoto zezemidlalo ezidinga uphethiloli we-premium unleaded ofinyelela kumasenti angu-20 ilitha ngaphezulu.

Kodwa-ke, njengomthetho ojwayelekile, uzokhokha u-10-15% ngaphezulu ngemoto esebenza ngodizili, ngakho-ke udinga ukuthola isibali bese ubheka ukuthi kuzokuthatha iminyaka emingaki ukubuyisela lezo zindleko zokuqala ekongeni kwepompo. Ukukubeka kalula, uma uhamba ngamamayela amaningi, ukonga kukaphethiloli kadizili kuzoheha, futhi nakakhulu uma amanani kaphethiloli eqhubeka nokukhuphuka.

Ukuthola okwengeziwe ethangini kusho uhambo olumbalwa oluya ku-servo, olungakongela isikhathi nama-calories (demeke lezo zibali ezilingayo ezimbozwe ushokoledi).

Uma uthenga imoto encane, eshibhile eyonga uphethiloli ngisho nenjini kaphethiloli, izindleko ezengeziwe kuba nzima ukuzithethelela.

Uma ubheka oshayelayo, udizili awunalo isasasa ngenxa yokuthi awawathandi amarev aphezulu njengophethiloli, kodwa awenza kakhulu uma ephansi.

I-torque ingamandla amakhulu edizili, okusho ukuthi ingakwazi ukusunduza isuke kulayini futhi iyakwazi nokudonsa izinto ezisindayo. Ngenxa yayo yonke leyo torque, uphethiloli kadizili awukhuphuki ngokushesha njengophethiloli uma wengeza, yingakho kuwuwoyela okhethwayo emalolini amakhulu.

Ngokuhamba kwesikhathi izimoto zikadizili zingase zehle ngokushesha kunezimoto zikaphethroli (ikakhulukazi uma kuyi-VW) futhi kunengozi yokuthi lokhu kungaba kubi kakhulu uma sibheka lokhu esikwaziyo manje mayelana negesi ekhishwayo.

Iqiniso Elibi

Udizili wesimanje umakethwa njengophephile futhi uhlanzekile, kodwa ucwaningo lwakamuva luveze iqiniso elingemnandi.

Abakhiqizi abakhulu bahlulekile ukufanisa imiphumela yabo yelebhu, bakhipha amazinga ayingozi naphezulu e-nitrogen dioxide.

Ukuhlolwa kwangempela kwama-29 Euro 6 udizili kubonise ukuthi konke ngaphandle kwesihlanu kwephule imingcele yokungcola, futhi abanye baqopha izikhathi ezingu-27 inani elivumelekile lokukhishwa okunobuthi.

Abakhiqizi abakhulu abanjengoMazda, BMW kanye neVolkswagen, abathengisa izinjini zikadizili ezifanayo lapha, abakwazanga ukuqhathanisa imiphumela yabo yaselabhu ekuhlolweni okwenziwa ephephandabeni i-The Sunday Times e-UK mayelana namazinga ayingozi futhi aphezulu e-nitrogen dioxide.

Injini kadizili i-Mazda6 SkyActiv yeqe imithetho ye-Euro 6 izikhathi ezine, i-X3 ye-BMW idonsa ngawo wonke amasondo yeqe okusemthethweni cishe izikhathi eziyishumi, kanti iVolkswagen Touareg yenze ngendlela emangalisayo, izikhathi ezingu-10 inani eliphakeme elibekwe imithetho ye-EU.

Kodwa-ke, iKia Sportage yayiyimbi kakhulu, yehlisa izikhathi ezingama-27 kunomkhawulo we-Euro 6.

Ukuchayeka kwe-nitrogen dioxide kubangela isifo esinzima samaphaphu nesifo senhliziyo, kanye nokungenwa kalula kwesifuba somoya, ukungezwani komzimba nezinto ezithile kanye nezifo ezihamba emoyeni. Igesi enobuthi nayo iye yahlotshaniswa nesifo sokufa kwezinsana ngokuzumayo, ukuphuphunyelwa kwezisu, nokukhubazeka kokuzalwa.

I-World Health Organization ilinganisela ukuthi i-nitrogen dioxide ibangela ukufa kwabantu abangaphezu kuka-22,000 XNUMX unyaka ngamunye eYurophu, lapho cishe ingxenye yazo zonke izimoto isebenzisa uwoyela kaphethiloli.

Udizili benza cishe ingxenye yesihlanu yezimoto zase-Australia, kodwa amanani abo emigwaqweni yethu akhule ngamaphesenti angaphezu kwangu-96 kule minyaka emihlanu edlule.

Njengamanje abantu base-Australia bashisa amalitha kadizili acishe abe yizigidi eziyizinkulungwane ezintathu ngonyaka ezimotweni kuphela, kanti amanye amalitha ayizigidi eziyizinkulungwane ezingu-9.5 asetshenziswa ezimotweni zentengiso.

Cishe amaphesenti angu-80 okungcola kwe-nitrogen dioxide emadolobheni ase-Australia avela ezimotweni, amaloli, amabhasi namabhayisikili.

Enye yezimoto ezephule imingcele yaseYurophu esivivinyweni sase-UK iMazda6 esebenzisa udizili edonsa ngenjini engu-2.2 litre SkyActiv efana neCX-5. IMazda Australia idayisa amaCX-2000 angaba ngu-5 XNUMX ngenyanga, kanti imoto eyodwa kweziyisithupha ingudizili.

Uphethiloli wedizili we-SkyActiv ohloliwe wenza isilinganiso esiphindwe kane kunomkhawulo we-Euro 6 lapho ushayela emzileni wasemadolobheni.

Umkhulumeli wakwaMazda e-UK uthe yize yehlulekile ukuhlolwa, amazinga ase-Europe amayelana nokungaguquguquki kokulinganisa kunokukhishwa kwangempela.

"Ukuhlolwa kwamanje kuklanyelwe ukukhombisa umehluko phakathi kwezimoto ezisekelwe ezimweni eziqinile zaselabhorethri, ukuqinisekisa ukungaguquguquki kubo bonke abakhiqizi nokuvumela amakhasimende ukuthi azikhethele ngokusekelwe emininingwaneni etholwe ngaphansi kwezimo ezifanayo," kusho i-Mazda.

“Umjikelezo wokuhlola awuphelele, kodwa unikeza umthengi umhlahlandlela lapho ekhetha khona imoto, ngokusekelwe ezintweni ezibalulekile - ezemvelo nezezimali.

“Nokho, siyakuqaphela ukulinganiselwa kokuhlolwa kanye neqiniso lokuthi akuvamile ukubonisa ukushayela kwangempela; umklomelo we-Euro 6 usekelwe esivivinyweni esisemthethweni hhayi ezinombolweni zangempela.”

Izindinganiso zokungcola zase-Australia zisibeka engozini enkulu yokuchayeka kumakhemikhali ayingozi.

Imiphumela edumazayo yakwaMazda igqitshwe yiKia Sportage, ekhiphe izinga elingaphezu kuka-20 izinga elisemthethweni le-nitrogen dioxide.

Okhulumela iKia Australia uKevin Hepworth uzosho nje ukuthi izimoto zakwaKia ziyahlangabezana nezindinganiso zokukhipha umoya.

"Izimoto esiziletha e-Australia zithobela imithetho yase-Australia yokuklama," esho.

"Asizange sibambe iqhaza ekuhlolweni futhi ngeke sikwazi ukuphawula nganoma yini."

I-WHO ilinganisela ukuthi ukungcoliswa komoya kubangela ukufa ngaphambi kwesikhathi kwezigidi ezingu-3.7 ngonyaka emhlabeni wonke, ikubiza ngokuthi “yingozi enkulu kunazo zonke yezempilo yemvelo”.

Izinhlanganisela ezimbili eziyinhloko neziyingozi kakhulu ekungcolisweni komoya i-nitrogen dioxide kanye ne-particle; umule omuhle kakhulu kuma-exhausts edizili.

Umoya wase-Australia uphakathi kwezindawo ezihlanzeke kakhulu emazweni athuthukile, kodwa noma kunjalo, ukungcoliswa komoya kubulala abantu base-Australia abangaphezu kuka-3000 XNUMX ngonyaka, inani eliphindwe cishe kathathu kunalabo abasezingozini zezimoto.

I-Australian Medical Association ithi izindinganiso zokungcola zase-Australia zisibeka engozini enkulu yokuchayeka kumakhemikhali anobuthi.

"Izindinganiso zamanje zekhwalithi yomoya e-Australia zilandela izindinganiso zamazwe ngamazwe futhi azihambisani nobufakazi besayensi," kusho i-AMA.

Udizili usaqhubeka nokuba nedumela e-Australia njengenketho ehambisana nemvelo enomnotho ongcono kaphethiloli, okusho ukuthi ukukhishwa kwekhabhoni dioxide encane, futhi udizili wesimanje uthengiswa njengamayunithi obuchwepheshe obuphezulu ashisa ngokuhlanzekile.

Nakuba lokhu kungase kube yiqiniso elebhu, ukuhlolwa komhlaba wangempela kufakazela ukuthi yinqwaba yomoya oshisayo, ongcolile.

Ingabe izinzuzo zokusebenza kahle nomzamo ohehayo zanele ukuze ucabangele udizili? Sazise kumazwana angezansi.
