I-Regular Gas vs. Premium Gas: Uyini Umehluko Futhi Ingabe Kufanele Nginakekele?

Ukwenza ucwaningo olwengeziwe oludingekayo ukuze wonge amadola ambalwa kuwumkhuba ojwayelekile kwabaningi bethu. Ngakolunye uhlangothi, lapho isikhwama sethu semali sibonakala sikhuluphele kunokuvamile, sivame ukuchitha ngokukhululeka. Kodwa uma kuziwa empompini, ingabe kunengqondo ukubeka igesi evamile emotweni okufanele ishaje i-premium? Ingabe kunengqondo ukuthela uphethiloli wezinga eliphezulu emotweni edinga njalo nje? Izimpendulo zingakumangaza.

Injini isebenzisa kanjani uphethiloli?

Ukuze uqonde umehluko kuphethiloli, kuyasiza ukwazi kahle ukuthi injini yakho isebenza kanjani uma isebenzisa igesi. Uphethiloli usiza ekushiseni, okwenzeka lapho ipulaki yenhlansi iletha umsinga kagesi omncane okhela ingxube ethile yomoya nophethiloli egumbini elivuthayo. Amandla adalwe kulokhu kusabela ashayela ama-piston kumasilinda ashayela i-crankshaft, anikeze imoto yakho amandla ewadingayo ukuze ihambe.

Ukusha kuyinqubo ehamba kancane, futhi inani lenhlansi lanele ukuthungela ingxube yomoya/yephethiloli eduze kwe-spark plug, enwebeka kancane ukuze ithungele yonke enye into. Injini ilungiselelwe le mpendulo ukuze ikwazi ukumunca amandla amaningi ngangokunokwenzeka, futhi izinjini eziningi ziklanywe ngendlela ehlukile ngezinjongo ezihlukene (isibonelo, imoto yezemidlalo yakhelwe amandla, kuyilapho imoto eyingxube yemoto yakhelwe ukonga uphethiloli). futhi wonke umuntu usebenza ngendlela ehlukile ngenxa yalokho.

Ukuthuthukisa injini ngale ndlela kubalulekile ngenxa yezizathu eziningana. Ingxube ye-air-fuel, lapho i-flame front ingakafinyeleli khona, ishintsha kakhulu ingcindezi kanye nezinga lokushisa ngaphambi kokusabela. Uma izimo kusilinda ziqukethe ukushisa okukhulu noma ukucindezela kwengxube yomoya/yephethiloli, izovutha ngokuzenzekelayo, okuholela ekushayeni kwenjini noma "ukuqhunyiswa". Lokhu kubuye kubizwe ngokuthi "ukungqongqoza" futhi kudala umsindo okhalayo njengoba ukusha kungenzeki ngesikhathi esifanele ukuthi injini isebenze kahle. Ukungqongqoza kwenjini kungase kungabi nalutho nhlobo noma kube nemiphumela emibi kakhulu uma kunganakwa.

Uyini uphethiloli futhi ubiza kanjani?

Uwoyela uyinhlanganisela ye-hydrocarbon ehlanganisa ikhabhoni namanzi njengezingxenye eziyinhloko. Uphethiloli uxutshwa ngokwezindlela zokupheka ezikhethekile, kuhlanganise nama-hydrocarbon angaba ngu-200 ahlukene avela kuwoyela. Ukuze kuhlolwe ukumelana nokugoqa kukaphethiloli, kusetshenziswa ama-hydrocarbon amabili: i-isooctane ne-n-heptane, inhlanganisela enquma ukuguquguquka kukaphethiloli ngokwamandla omlilo. Isibonelo, i-isooctane imelana nokuqhuma okuzenzakalelayo, kuyilapho i-n-heptane isengozini yokuqhuma okuzenzakalelayo. Uma sifingqwa ngefomula ethile, sithola isilinganiso: ngakho-ke uma u-85% weresiphi iyi-isooctane futhi u-15% kuyi-n-heptane, sisebenzisa u-85 (iphesenti le-isooctane) ukuze sinqume izinga noma izinga le-octane.

Nalu uhlu olubonisa amazinga e-octane ajwayelekile kumaresiphi ajwayelekile kaphethiloli:

• 85-87 - Okuvamile
• 88-90 - Okuphakeme
• 91 nangaphezulu - I-Premium

Zisho ukuthini izinombolo?

Lezi zinombolo zinquma ukuthi uphethiloli uvutha ngokushesha kangakanani, uma kubhekwa izimo zenjini ezosetshenziswa kuyo. Ngakho-ke, uphethiloli we-premium awunikezi amandla amaningi enjini kunophethiloli ojwayelekile; lokhu kuvumela izinjini ezinolaka (ake sithi, izinjini ezine-turbocharged) ukuthi zithole amandla engeziwe kugalani likaphethiloli. Kulapho kufika khona izincomo ngekhwalithi yamafutha ezimotweni.

Njengoba izinjini ezinamandla kakhulu (i-Porsche 911 Turbo) zikhiqiza ukushisa nokucindezela okwengeziwe kunezinjini ezinamandla kancane (i-Honda Civic), zidinga izinga elithile le-octane ukuze lisebenze kahle. Ukuthambekela kwenjini ukungqongqoza kuncike esilinganisweni sokucindezela, okubuye kube nomthelela ekuklanyweni kwegumbi lomlilo uqobo. Isilinganiso esiphezulu sokucindezela sinikeza amandla engeziwe ngesikhathi sokushaywa unhlangothi, okufaka isandla ngokuqondile ekucindezelweni okuphezulu kanye nezinga lokushisa kusilinda. Ngakho-ke, uma ugcwalisa injini ngophethiloli we-octane onganele, inomkhuba ophakeme wokungqongqoza.

Kusho ukuthini lokhu ekuphatheni?

Uhlelo lweCar and Driver luhlole ukuthi izinhlobo ezahlukene zikaphethiloli zikuthinta kanjani ukusebenza kwenjini kwezimoto namaloli ahlukene. Ocwaningweni olunezingxenye ezimbili, bahlole izimoto eziningi (ezinye zisebenzisa uphethiloli ovamile kanti ezinye zikhokha kakhulu) ngegesi evamile, bakhipha amathangi, bawahambisa ngegesi ephambili izinsuku ezimbalwa, base bephinda bevivinywa. Ekugcineni, noma yikuphi ukuzuza kokusebenza okuvela ekukhokheleni iprimiyamu bekukude kakhulu nokubalulekile futhi bekungafanele neze ukukhuphuka kwentengo. Ngakolunye uhlangothi, izimoto eziningi (ezintathu kwezine) zenze kabi kakhulu uma zingawusebenzisi uphethiloli osikiselwayo.

Izinjini zezimoto zakhelwe ukugcina izinga elithile lokusebenza elithuthukisiwe, futhi izincomo zikaphethiloli zenziwa kucatshangwa ngalokho. Ukwehluleka kwenjini ngokushesha kungase kungenzeki, kodwa kungase kube nemiphumela elimazayo yesikhathi eside engaholela ekulungiseni okubizayo.

Ingabe ugcwalise imoto ngophethiloli ongafanele? Shayela umakhenikha ukuze akuhlole ngokushesha okukhulu.
