Ubuchwepheshe benjini kadizili bushintsha usuku nosuku, imboni yenjini kadizili inekusasa eliqhakazile.Ngokuthuthuka okuqhubekayo kobuchwepheshe, injini kadizili isazoba sesikhundleni esiphezulu emandleni okuthutha asindayo, amandla amakhulu ezimboni, amandla olwandle, imishini yobunjiniyela, imishini yezolimo, izimoto zamasosha kanye neminye imikhakha yezicelo emijikelezweni yokuthuthukiswa kobuchwepheshe yesikhathi esizayo, enemakethe ebanzi. isidingo kanye nobungqabavu obuqinile.Inqubekelaphambili yezobuchwepheshe yenjini kadizili isazodlala indima ebalulekile nebalulekile ekufezeni ukonga ugesi kanye nokunciphisa ukungcola kanye nokubhekana nokushintsha kwesimo sezulu.Imboni yezinjini zikadizili isagcwele amandla futhi isazoqhubeka nokwenza okuningi eminyakeni engu-50 ezayo.
Ngokuqhubeka okuqhubekayo kobuchwepheshe benjini kadizili, ibambe iqhaza elibalulekile ekongeni amandla kanye nasekunciphiseni ukungcola, futhi amandla okuqhubeka nokuqaphela ukonga amandla kanye nokunciphisa ukungcola makhulu, futhi ubuchwepheshe bungasetshenziswa ngokuqinile.
Ukusetshenziswa kukaphethiloli kwezinjini zikadizili kwehla njalo.Injini ye-diesel, njengenjini yokushisa enamandla kakhulu ekuguquleni amandla, inomphumela wokonga amandla omangalisayo uma iqhathaniswa neminye imishini yamandla.Ngokwemiphumela yakamuva yocwaningo, ukusebenza kahle kwenjini kadizili kusuka ku-45% kuya ku-50% wamanje, ukukhishwa kwegesi okusondele ku-zero kunethuba lokudayiswa.Isibonelo, uma amandla okushisa enjini kadizili enyuka asuka ku-45% aye ku-50%, ukusetshenziswa kukaphethiloli kwemoto yonke kungancishiswa ngo-11%, futhi ukusetshenziswa konyaka kukawoyela we-diesel kanye ne-carbon dioxide ephuma kuwo wonke umphakathi kungancipha. kwehle ngamathani angaba yizigidi ezingu-19 kanye namathani ayizigidi ezingu-60.Ngokuzayo, kungenzeka futhi ukuthi kuthuthukiswe ukusebenza kahle kwezinjini zikadizili kuye ku-55% ngokusebenzisa ubuchwepheshe obusebenzayo bokuvutha nokubuyiswa kokushisa, ngaleyo ndlela kuncishiswe ukusetshenziswa kukaphethiloli kwemoto yonke ngama-22% njengamanje.Umphakathi wonke unganciphisa ukusetshenziswa kukadizili cishe ngamathani ayizigidi ezingu-38 kanye nokukhishwa kwesikhutha ngamathani ayizigidi eziyi-120 minyaka yonke.
Ukukhishwa kwezinto ezingcolile ezinjinini zikadizili kuyaqhubeka nokuncipha.Kusukela ekusetshenzisweni komthetho we-National 1 emission regulation ngo-2000 kuya ekusetshenzisweni kwezinga le-National 6 emission ngo-2019, izinga lokukhishwa kwemikhiqizo yenjini kadizili e-China lisalele ngemuva kweYurophu ngezigaba ezimbili ekuqaleni kwekhulunyaka, futhi manje i-National 6. ukulawulwa kokungcoliswa kwezimoto kufeze indima ehamba phambili kumazinga okulawula ukungcoliswa kwezimoto emhlabeni jikelele.Uma kuqhathaniswa nenjini kadizili yaseChina 1 yango-2000, imikhiqizo kadizili yaseChina engu-6 yehlise ukukhishwa kwezinhlayiya ngo-97% kanye nokukhishwa kwe-nitrogen oxide ngo-95%.Ngokwemiphumela yakamuva yocwaningo, ukukhishwa kwenjini kadizili okusondele ku-zero kunethuba lokudayiswa, kungaqhubeka nokunciphisa ukungcola okungcolisayo.Isinyathelo esilandelayo kuzoba ukusheshisa ukushintshwa kwemikhiqizo ekhona kadizili engcolisa kakhulu emakethe ngokusetshenziswa ngokugcwele kwemithethonqubo ye-State 6 yokukhipha izinjini zikadizili emgwaqeni kanye nemithetho yezigaba ezine yokukhipha umoya ezinjinini ezingezona ezemigwaqo, ukuze ukukhuthaza ukukhushulwa kwesidingo sabathengi ngokusetshenziswa okuphansi kukaphethiloli kanye nesisi esikhishwayo.
