Uphethiloli ngomjovo oqondile
Ziyanda izimoto emakethe yethu ezinezinjini zikaphethiloli ezinomjovo oqondile wamafutha. Ingabe kufanelekile ukuthenga?
Izinjini ezinomjovo oqondile kaphethiloli kufanele zonga kakhulu kunalezi zamanje. Ngokwethiyori, ukonga ekusetshenzisweni kukaphethiloli kufanele kube ngu-10%. Kubenzi bezimoto, lokhu kuyisici esibalulekile, futhi cishe wonke umuntu wenza ucwaningo ngama-powertrain anjalo.
I-Volkswagen igxile kakhulu ekujovweni okuqondile, ikakhulukazi ishintsha izinjini ezijwayelekile ngamayunithi omjovo oqondile, abizwa nge-FSI. Emakethe yethu, izinjini ze-FSI zingatholakala ku-Skoda, Volkswagen, Audi kanye nezihlalo. I-Alfa Romeo ichaza izinjini ezifana ne-JTS, nazo ezitholakala kithi. Amayunithi amandla anjalo 
futhi inikeza iToyota neLexus.
Umqondo womjovo oqondile kaphethiloli uwukwenza ingxube ngqo ekamelweni elivuthayo. Ukwenza lokhu, i-electromagnetic injector ifakwa ekamelweni elivuthayo, futhi umoya kuphela unikezwa nge-valve yokungena. I-Fuel ijojowe ngaphansi kwengcindezi ephezulu kusuka ku-50 kuya ku-120 bar, eyenziwe ngepompo ekhethekile.
Kuye ngezinga lomthwalo wenjini, isebenza kumodi eyodwa kwezimbili zokusebenza. Ngaphansi komthwalo omncane, njengokungenzi lutho noma ukushayela ngesivinini esingaguquki endaweni ebushelelezi, eneleveli, ingxube enciphile ye-stratified ifakwa kuyo. Kukhona uphethiloli omncane engxubeni engenawo amandla, futhi konke lokhu kukonga okumenyezelwe.
Kodwa-ke, lapho usebenza ngomthwalo ophakeme (isb, ukusheshisa, ukushayela ukukhuphuka, ukudonsa inqola), futhi ngisho nangesivinini esingaphezu kuka-3000 rpm, injini ishisa ingxube ye-stoichiometric, njengasenjini evamile.
Sibheke ukuthi kubukeka kanjani uma sizijwayeza ukushayela iVW Golf enenjini engu-1,6 hp 115 FSI. Lapho ushayela emgwaqeni omkhulu nomthwalo omncane enjinini, imoto yayidla amalitha angu-5,5 kaphethiloli ngebanga elingu-100 km. Lapho ushayela ngendlela eguquguqukayo emgwaqeni "ojwayelekile", amaloli adlulayo nezimoto ezihamba kancane, iGalofu idla amalitha ayi-10 ngebanga elingu-100 km. Lapho sibuya ngemoto efanayo, sahamba ngokuthula, sisebenzisa amalitha angu-5,8 ngebanga lika-100 km.
Sithole imiphumela efanayo sishayela iSkoda Octavia neToyota Avensis.
Indlela yokushayela idlala indima ebalulekile ekusetshenzisweni kukaphethiloli wenjini yomjovo oqondile kaphethiloli. Kulapho ukushayela okunciphile kubalulekile khona. Abashayeli abakhetha isitayela sokushayela esinolaka ngeke bazuze kumodi eyongayo yokusebenza kwenjini. Kulesi simo, kungase kube ngcono ukuthenga eshibhile, yendabuko.
