Kutshanje, bekukho iindaba ezibalaseleyo kwihlabathi kwicandelo leenjini zaseTshayina. I-Weichai Power yenze ijenereyitha yokuqala yedizili esebenza kakuhle ngobushushu obungaphezulu kwe-50% kwaye isetyenziswa kwezorhwebo kwihlabathi liphela.
Ayikuko nje kuphela ukuba ukusebenza kakuhle kobushushu bomzimba wenjini kungaphezulu kwe-50%, kodwa ikwanokuhlangabezana ngokulula neemfuno zesizwe ze-VI / Euro VI zokukhupha kwaye ifezekise imveliso enkulu. Iinjini ezinkulu zamanye amazwe ezifana neenjini zedizili zeMercedes Benz, Volvo, Cummins ezikwinqanaba elifanayo lokusebenza kakuhle zisekwinqanaba lelebhu, kwaye zinesixhobo sokubuyisa ubushushu obumdaka. Ukuze kwenziwe le njini, iWeichai ityale iminyaka emi-5, i-4.2 yeebhiliyoni kunye namawaka abasebenzi be-R & D. Sele kudlule inkulungwane enesiqingatha ukusukela ngo-1876 ukuba ukusebenza kakuhle kobushushu beenjini zedizili ezinkulu kwihlabathi kunyuke ukusuka kwi-26% ukuya kwi-46%. Uninzi lweemoto zepetroli zentsapho yethu azidlulanga kwi-40% ukuza kuthi ga ngoku.
Ukusebenza kakuhle kobushushu obuyi-40% kuthetha ukuba i-40% yamandla e-fuel enjini iguqulwa ibe ngumsebenzi we-crankshaft. Ngamanye amazwi, nangaliphi na ixesha unyathela i-pedal yegesi, malunga ne-60% yamandla e-fuel ayachithwa. La ma-60% zonke ziintlobo zelahleko ezingenakuphepheka.
Ke ngoko, okukhona ukusebenza kakuhle kobushushu kuphezulu, kokukhona ukusetyenziswa kancinci kwepetroli, kokukhona isiphumo sokonga amandla kunye nokunciphisa ukukhutshwa komoya sibaluleke ngakumbi.
Ukusebenza kakuhle kobushushu benjini yedizili kungadlula ngokulula i-40% kwaye kulwele ukufikelela kwi-46%, kodwa phantse kube ngumda. Ngaphezu koko, ukuphuculwa kwe-0.1% nganye kufuneka kwenziwe imizamo emikhulu.
Ukuze kwenziwe le injini esebenza kakuhle ngobushushu obuyi-50.26%, iqela le-Weichai R & D liphinde layila kwakhona i-60% yamawaka eendawo ezikwinjini.
Ngamanye amaxesha iqela linokuyiphucula kuphela indlela esebenza ngayo i-thermal nge-0.01% ngaphandle kokulala iintsuku ezininzi. Abanye abaphandi baphelelwe lithemba kangangokuba bafuna uncedo kwingcali yezengqondo. Ngale ndlela, iqela lithathe yonke i-0.1 yokunyuka kwendlela esebenza ngayo i-thermal njenge-node, laqokelelana kancinci, laza latyhala ngamandla. Abanye abantu bathi kuyimfuneko ukuhlawula ixabiso eliphezulu kangaka ukuze kuqhutyekwe phambili. Ngaba le 0.01% inengqiqo? Ewe, inengqiqo, ukuxhomekeka kwangaphandle kweTshayina kwioyile yi-70.8% ngo-2019.
Phakathi kwazo, injini yokutshisa yangaphakathi (injini yedizili + injini yepetroli) itya i-60% yeoli iyonke esetyenziswa yiTshayina. Ngokusekelwe kwinqanaba langoku le-46% kushishino, ukusebenza kakuhle kobushushu kunokwandiswa ukuya kwi-50%, kwaye ukusetyenziswa kwedizili kunokwehliswa nge-8%. Okwangoku, iinjini zedizili ezinzima zaseTshayina zinokunyuswa ziye kwi-10.42 yezigidi zeetoni ngonyaka, nto leyo enokonga i-10.42 yezigidi zeetoni zekhabhoni diokside. Iitoni ezingama-33.32 ezigidi, ezilingana nesinye kwisihlanu semveliso yedizili iyonke yaseTshayina ngo-2019 (iitoni ezili-166.38 ezigidi)
