Ishishini Lokwakha Iinqanawa
Kwiminyaka yakutshanje, ishishini lokwakha iinqanawa laseTshayina lifumene uphuhliso olungazange lubonwe ngaphambili, ngokwezibalo ezifanelekileyo zibonisa ukuba ngo-2013 ukwakhiwa kweenqanawa zaseTshayina kwagqiba iitoni ezingama-4534 zobunzima bokufa, ii-odolo ezintsha zafikelela kwi-69.84 yezigidi zeetoni zobunzima bokufa. Ukususela ngo-2010 njengokwakhiwa kweenqanawa kwihlabathi liphela, iTshayina ihlale kwindawo yoku-1 kwiminyaka emi-4 ehlabathini.
Ishishini lokuvelisa iinqanawa liyimbonakaliso yenqanaba lobuchwepheshe bokuvelisa ilizwe. Injini yedizili yolwandle yinxalenye ephambili yokwakha iinqanawa, uphuhliso lwayo luqhuba ishishini lezixhobo zoomatshini ngakumbi uphuhliso olukhulu lwezixhobo zoomatshini ezinzima kunye nokuvelisa izinto ezintsha, kwaye ikwanazo neemfuno ezingqongqo kakhulu zezixhobo zokulinganisa ukuze zilungelelaniswe nokulinganiswa kwezi ndawo zinkulu zokuchaneka. Uhlobo lweenxalenye kunye namacandelo enjini yedizili yolwandle zenziwe ikakhulu ziindawo zebhokisi, kubandakanya i-crankcase ephezulu nesezantsi, intonga yokudibanisa, i-crankshaft, intloko yesilinda, iindawo zegobolondo ye-flywheel njalo njalo. Ngokuphathelele ezinye iindawo, inemisebenzi yobukhulu obukhulu, izinto zokulinganisa ezingaphezulu kunye nokuchaneka okuphezulu. Ngoko ke isixhobo sokulinganisa ibhulorho enkulu kunye ne-gantry enkulu sisisombululo esifanelekileyo kwiindawo kunye namacandelo enjini yedizili yombhede, ngakumbi ukulinganiswa komzimba oyintloko.
Umzimba oyintloko njengesiseko senjini yedizili, uxhasa injini yedizili yonke. Zonke iindawo kunye nenkqubo encedisayo zibekwe ngokuthe ngqo okanye ngokungathanga ngqo emzimbeni, ezenza inkangeleko encinci kwaye kulula ukuyigcina. Ke ngoko, ukufunyanwa komzimba oyintloko yeyona ndlela inzima yokulinganisa iindawo zenjini yedizili.
Uthotho lwe-SPOINT lunokwanelisa imfuno yokulinganisa izinto ezinkulu. Sineteknoloji ephucukileyo, iinkqubo zokuvelisa ezingqongqo ukubonelela ngezisombululo zokulinganisa ezichanekileyo nezisebenzayo zeenqwelo-moya, ukhuselo lwesizwe, ukuveliswa kweemoto, ukungunda, iinqanawa, njalo njalo.
