Ithini inombolo ye-octane kaphethiloli
I-Octane ikhono likaphethiloli ukumelana nokucindezelwa. Izimoto ezisebenza kahle zidinga uphethiloli we-octane ophezulu ukuze zithuthukise ukusebenza kahle nokusebenza.
Iningi labashayeli likhuphukele egalaji likaphethiloli lafaka uphethiloli wezinga elithile le-octane. Ngokuvamile, iziteshi zikaphethiloli zinikeza izinhlobo ezintathu zikaphethiloli ezinezilinganiso ezihlukile ze-octane.
Nokho, akuthina sonke esaziyo ukuthi inombolo ye-octane iyini, futhi siyazi kuphela ukuthi omunye unama-87, omunye una-89, kanti iprimiyamu ine-octane engu-91.
Ithini inombolo ye-octane kuphethiloli?
Impendulo emfushane iwukuthi i-octane iyisilinganiso sokuthi uphethiloli okwazi ukumelana nokucindezelwa okungakanani ngaphambi kokuba uthungele. Ngokwabantu abavamile, uma izinga le-octane liphezulu, mancane amathuba okuthi uphethiloli uvutha uma unengcindezi ephezulu futhi kulimaze injini yakho.
Yingakho izimoto ezisebenza kahle ezinezinjini zokucindezela eziphezulu zidinga uphethiloli ophakeme we-octane (premium). Empeleni, amafutha e-octane aphezulu ahambisana nezinjini zokucindezela eziphezulu, ezingathuthukisa ukusebenza kahle nokusebenza, okungenzeka zehlise ukukhishwa kwekhabhoni ngokushisa uphethiloli ngokuphelele.
Ezingxenyeni eziningi zase-US, uphethiloli ojwayelekile ongena-lead unesilinganiso se-octane esingu-87, ibanga elimaphakathi ngu-89, kanti i-premium ngu-91-93. Lezi zinombolo zinqunywa ukuhlolwa kwenjini, okuholela ezilinganisweni ezimbili: inombolo ye-octane yocwaningo (RON) kanye nenjini. Inombolo ye-Octane (MCH). ).
Abanikazi bezimoto abaningi bangase bangazi ukuthi injini evuthayo yangaphakathi kaphethiloli isebenza kanjani noma kungani i-octane ibalulekile. Abanye bangase bacabange ngisho ukuthi ukuthengisa uphethiloli ovamile kuphethiloli we-premium, ngenxa yamanani aphansi naphakeme, kuyindlela yokuthengisa "uphethiloli ovamile" "kuphethiloli wefancy". Eqinisweni, izinhlobo ezahlukene zibhekisela ezinhlotsheni zezinjini zezimoto ezidinga amazinga ahlukene e-octane kuphethiloli.
Isebenza kanjani i-Octane enjinini?
Kuye ngomklamo wenjini yemoto, i-octane idlala indima ebalulekile ekusebenzeni kwenjini futhi ikala ikhono lokumelana nokusha okuzenzakalelayo, okuvame ukwaziwa ngokuthi ukuqhunyiswa.
Injini kaphethiloli evuthayo yangaphakathi icindezela ingxube yomoya nophethiloli kumasilinda ayo, ngaleyo ndlela ikhulise izinga lokushisa nokucindezela kwengxube. Ingxube yomoya/yephethiloli ibaswa yinhlansi phakathi nokucindezelwa, futhi ukushiswa okuwumphumela kukhipha amandla okushisa agcina eshayela imoto. Ukungqongqoza kungenzeka ezingeni lokushisa eliphezulu ngokwanele (njengomphumela wokucindezelwa) kumasilinda enjini. Ngokuhamba kwesikhathi, ukungqongqoza kunciphisa ukonga kukaphethiloli wemoto, kuphuce injini amandla, futhi kubangele nokulimala kwenjini.
