Umzimba we-Yiandi 645 injini yedizi ye-Discon yenziwa nge-carbon ye-carbon ye-carbon ye-weltied kunye, ngaphandle kwezindlu eziphambili zokuthwala okwenziwa ngentsimbi yentsimbi. Xa kuthelekiswa nebhloko ye-injini ye-567 injini yedizili, i-645 injini yedizili inebhokisi enkulu yomoya, enokuthi inciphise ukudodobala kokutya kunye nokuqinisekisa ukuba ubisi lwe-pillminds kwi-cylinders. Akukho jelo ipholileyo yamanzi kwi-angle efakwe kwi-V-kwinxalenye ephezulu yeZiko lomatshini, elinokunciphisa uxinzelelo lwe-thermal lomzimba womatshini kunye nengxaki ebangela. I-crankshaft ivela kwintsimbi yekharbon eqhelekileyo. Ijenali icinyiwe ngokufudumeza. Ububanzi bejenali ephambili ziimilimitha ezili-190 kunye nejenali ye-rod yokudibanisa ziimilimitha ezili-165. Ijacket yangaphandle ye-piston yenziwa nge-alloy yentsimbi kwaye yamkela isakhiwo esijikelezayo esijikelezayo, evumela ukuba iPiston ifumane umthwalo osasazekileyo kunye nokunxiba. I-piston ipholile yi-injini ye-injini ekhutshiwe kwi-nozzle kwigumbi lokupholisa iPiston nge-osciciclorence. Ubomi benkonzo yepiston banokufikelela kwiiyure ezingama-25,000. I-Cylinder Liner enejeyithi yamanzi yenziwa nge-Afloy ye-Afloty yentsimbi. Iinjini ezingama-645 ze-dielines zedizili zamkela ifrakti yefutha edityanisiweyo edibanisa impompo ye-pub ye-pieli ephezulu kunye nejeyili ipetroli kwiyunithi enye. Njengakwiinjini zedizili ezingama-567, ezingcelele ezingama-645 zamkela indinyana yokudibanisa ngokwahlukileyo kunye negesi yerhasi yerhasi yerhasi yerhasi ye-turbording, ukusombulula irhasi yerhasi yenjini yokuhamba kweenqanawa ezimbini. Xa injini yedizili iphantsi komthwalo ophantsi kwaye amandla aphethwe ngamandla asezantsi, i-crankshaft ye-injini yedizili iqhuba i-SuperCerger yeGears. Xa umthwalo we-injini yedizili uphakame, ukuqhuba i-turbine ukuya kujikeleza. Olu luyilo alunakuphucula ukukhawuleza kunye nomgangatho we-injini yedizili kwimithwalo ephantsi, kodwa inika umdlalo opheleleyo kwiinzuzo ze-turbocing kwimithwalo ephezulu.
