Muva nje, kube nezindaba ezisezingeni lomhlaba emkhakheni wezinjini zaseShayina. I-Weichai Power idale ijenereyitha yokuqala kadizili esebenza kahle ngokushisa okungaphezu kuka-50% futhi esetshenziswa kwezentengiselwano emhlabeni.
Akukhona nje kuphela ukuthi ukusebenza kahle kokushisa komzimba wenjini kungaphezu kuka-50%, kodwa futhi kungahlangabezana kalula nezidingo zokukhishwa kwe-VI / Euro VI kazwelonke futhi kufeze ukukhiqizwa okukhulu. Izinjini ezinkulu zakwamanye amazwe ezifana nezinjini zikadizili zeMercedes Benz, Volvo, Cummins zezinga elifanayo lokusebenza kahle zisesesigabeni selabhorethri, futhi zinedivayisi yokubuyisa ukushisa okulahliwe. Ukuze kwenziwe le njini, iWeichai itshale iminyaka emi-5, izigidigidi ezingu-4.2 kanye nezinkulungwane zabasebenzi be-R & D. Sekuphele ikhulu nesigamu kusukela ngo-1876 ukuthi ukusebenza kahle kokushisa kwezinjini ezinkulu zikadizili emhlabeni kukhuphuke kusuka ku-26% kuya ku-46%. Izimoto eziningi zikaphethiloli zomndeni wethu azidluli ku-40% kuze kube manje.
Ukusebenza kahle kokushisa okungu-40% kusho ukuthi u-40% wamandla kaphethiloli enjini uguqulwa ube umsebenzi wokukhipha we-crankshaft. Ngamanye amazwi, noma nini lapho unyathela i-pedal yegesi, cishe u-60% wamandla kaphethiloli uyachithwa. Lawa angu-60% ayizinhlobo zokulahlekelwa okungenakugwenywa.
Ngakho-ke, uma ukusebenza kahle kokushisa kuphakeme, ukusetshenziswa kukaphethiloli okuncane, kulapho umphumela wokonga amandla kanye nokunciphisa ukukhishwa komoya ubaluleke kakhulu.
Ukusebenza kahle kokushisa kwenjini kadizili kungadlula kalula u-40% futhi kulwele ukufinyelela ku-46%, kodwa cishe kungumkhawulo. Ngaphezu kwalokho, konke ukulungiswa okungu-0.1% kufanele kwenziwe imizamo emikhulu.
Ukuze kudalwe le njini esebenza kahle ngokushisa okungu-50.26%, ithimba le-Weichai R & D liphinde laklama kabusha u-60% wezinkulungwane zezingxenye enjinini.
Ngezinye izikhathi iqembu lingathuthukisa ukusebenza kahle kokushisa ngo-0.01% kuphela ngaphandle kokulala izinsuku eziningana. Abanye abacwaningi baphelelwe yithemba kangangokuthi badinga usizo kudokotela wengqondo. Ngale ndlela, iqembu lithathe konke ukwanda kokusebenza kahle kokushisa okungu-0.1 njenge-node, laqoqana kancane, futhi lacindezela kanzima. Abanye abantu bathi kuyadingeka ukukhokha inani eliphezulu kangaka ukuze kuthuthukiswe. Ingabe lokhu okungu-0.01% kunengqondo? Yebo, kunengqondo, ukuthembela kwangaphandle kwaseShayina kumafutha kungu-70.8% ngo-2019.
Phakathi kwazo, injini yokushisa yangaphakathi (injini kadizili + injini kaphethiloli) idla u-60% wokusetshenziswa kukawoyela okuphelele eShayina. Ngokusekelwe ezingeni lamanje lemboni elingu-46%, ukusebenza kahle kokushisa kungakhushulwa ku-50%, kanti ukusetshenziswa kukadizili kungancishiswa ngo-8%. Njengamanje, izinjini zikadizili ezisindayo zaseShayina zingathuthukiswa zibe amathani ayizigidi eziyi-10.42 ngonyaka, okungonga amathani ayizigidi eziyi-10.42 e-carbon dioxide. Amathani ayizigidi ezingama-33.32, okulingana nengxenye eyodwa kwezinhlanu zomkhiqizo kadizili ophelele waseShayina ngo-2019 (amathani ayizigidi eziyi-166.38)
