Imboni Yokwakha Imikhumbi
Eminyakeni yamuva nje, imboni yokwakha imikhumbi yaseShayina ithole intuthuko engakaze ibonwe, ngokusho kwezibalo ezifanele zibonisa ukuthi ngo-2013 ukwakhiwa kwemikhumbi yaseShayina kwaqeda amathani angu-4534 esisindo esibulalayo, ama-oda amasha afinyelela amathani ayizigidi ezingu-69.84 esisindo esibulalayo. Kusukela ngo-2010 njengokwakhiwa kwemikhumbi emhlabeni, iShayina ihlale endaweni yokuqala phakathi neminyaka emine emhlabeni.
Imboni yokukhiqiza imikhumbi iyisibonelo sezinga lobuchwepheshe bokukhiqiza ezweni. Injini yedizili yasolwandle iyizingxenye eziyinhloko zokwakha imikhumbi, intuthuko yayo iqhuba imboni yamathuluzi omshini ikakhulukazi ukuthuthukiswa kwamathuluzi omshini amakhulu asindayo kanye nokusungula izinto ezintsha, futhi inezidingo eziqinile kakhulu zemishini yokulinganisa ukuze ivumelane nokulinganiswa kwalezi zingxenye ezinkulu zokunemba. Uhlobo lwezingxenye nezingxenye zenjini yedizili yasolwandle zakhiwe kakhulu yizingxenye zebhokisi, kufaka phakathi i-crankcase ephezulu nephansi, induku yokuxhuma, i-crankshaft, ikhanda lesilinda, izingxenye zegobolondo le-flywheel nokunye. Uma kuqhathaniswa nezinye izingxenye, inemisebenzi yobukhulu obukhulu, izinto zokulinganisa eziningi kanye nokunemba okuphezulu. Ngakho-ke ithuluzi lokulinganisa ibhuloho elikhulu kanye ne-gantry enkulu liyisisombululo esifanele sezingxenye nezingxenye zenjini yedizili yombhede, ikakhulukazi ukulinganiswa komzimba oyinhloko.
Umzimba oyinhloko njengesisekelo senjini kadizili, usekela injini kadizili yonke. Zonke izingxenye kanye nohlelo olusizayo zigxile ngqo noma ngokungaqondile emzimbeni, okwakha ukubukeka okuqinile nokulula ukunakekela. Ngakho-ke, ukutholakala komzimba oyinhloko kuyindlela eyinkimbinkimbi kakhulu yokulinganisa izingxenye zenjini kadizili.
Uchungechunge lwe-SPOINT lungahlangabezana nesidingo sokulinganisa izinto ezinkulu. Sinobuchwepheshe obuthuthukisiwe, izinqubo zokukhiqiza eziqinile ukuze sinikeze izixazululo zokulinganisa ezinembile nezisebenzayo zezindiza, ukuzivikela kwezwe, ukukhiqizwa kwezimoto, isikhunta, imikhumbi, njalo njalo.
