Ngokukhula okuqhubekayo kwamanani kaphethiloli kanye nemithetho eqinile yokukhipha uphethiloli, abakhiqizi bezimoto nabakhiqizi bezinjini basebenzisa ngenkuthalo ubuchwepheshe obuhlukahlukene obuthuthukisiwe ukuze banciphise ukusetshenziswa kukaphethiloli kwenjini kanye nokukhipha umoya.

Amandla aqinile angaguquki asebenzisa ubuchwepheshe bokufafaza i-plasma engaphakathi kwembobo ethuthukisiwe ukuze afafaze ungqimba olukhethekile odongeni olungaphakathi lwembobo yesilinda, futhi asebenzise izingxenye ezihlukene zokumboza ukuze ahlangabezane nezidingo ezikhethekile zenjini, njengekhwalithi embi kaphethiloli kanye nokuguga ngokweqile. , ukuklwebheka noma ukugqwala okubangelwa isilinganiso se-exhaust gas recirculation rate (EGR).

Lobu buchwepheshe busetshenziswe ezinjinini zezimoto, zamaloli, zezithuthuthu nezasolwandle, kanye nama-cylinder liners ezinjini zikaphethiloli, izinjini zeziteshi zamandla kanye nama-compressor egesi.

Muva nje,Amandla kaZhenghengilethe ngempumelelo iqoqo lesibili likadizili wempilo endeisilinda injiniamalayini embonini eyaziwayo yenjini kadizili eChina.

Kule liner ye-cylinder yempilo ende, izinto zokugqoka ezikhethiwe ziyi-cermet composite, enenzuzo yokunciphisa kakhulu ukungqubuzana nokugqoka kodonga lwe-cylinder bore.

Ngesikhathi esifanayo, ngenxa yokuthi ukugqoka kuqukethe izinhlayiya ze-ceramic kanye nezakhi ezikhethekile, ukumelana kwayo nokugqwala kungathuthukiswa ngokwengeziwe, futhi impilo yayo yesevisi izoba yinde kakhulu kune-liner ye-cast iron cylinder.

I-Scania, umkhiqizi wamaloli angaphandle owaziwayo, usuvele wamukele inqubo efanayo yokufafaza kanye nezinto zokwakha njengamandla aqhubekayo enjini yakhe, eqaphela inganekwane yokuthi iloli layo alinawo ukuguqulwa ngamakhilomitha ayizigidi ezingu-3.

Njengamanje, amandla ka-Zhengheng aseqedile ukuthuthukiswa kobuchwepheshe bemikhiqizo efana ne-cylinder less aluminium alloy cylinder block, injini yempilo ende ye-diesel kanye ne-cylinder liner.Ifinyelele ukubambisana nabakhiqizi abaningi bezimoto ezifuywayo abaziwayo kanye nabakhiqizi benjini enkambweni yokufafaza imbobo yangaphakathi, futhi inganikeza amakhasimende izinsiza zokuma okukodwa ukusuka kungenalutho, umshini, ukufafaza ukuya emikhiqizweni yokugcina yokucija.
