Umzimba we-Yiandi 645 Series Diesel Injini yenziwe ngamapuleti ajwayelekile e-carbon yensimbi ehlanganiswe ndawonye, ngaphandle kwendlu enkulu ebizwa ngensimbi eyenziwe ngensimbi eyakhiwe. Uma kuqhathaniswa ne-Injini Excy yenjini ye-567 Series Diesel Injini, injini ye-645 Series Diesel inebhokisi elikhudlwana lokuphuza umoya, elinganciphisa ukukhishwa kwemali nokuqinisekisa ukulethwa komoya okufanayo kumasilinda amaningi. Asikho isiteshi esipholile samanzi e-angle esenziwe ngamanzi engxenyeni engenhla yomshini womshini, onganciphisa ukucindezela okushisayo komzimba womshini kanye nokulimala kwezenkolo. I-crankshaft yakhiwa ngensimbi evamile yekhabhoni. Ijenali icinywe ngokufudumeza. Ububanzi bephephabhuku eliyinhloko bungamamilimitha angama-190 kanye nephephabhuku le-Connecting Ronner linamamilimitha ayi-165. Ijekethi yangaphandle yepistoni yenziwa nge-alloy cast iron impahla futhi yamukele isakhiwo esijikelezayo esijikelezayo, okwenza ukuthi i-piston ikwazi ukwabiwa ngokulinganayo umthwalo wokushisa nokugqoka. I-piston iphonswe yi-oyili yenjini efafazwe kusuka ku-nozzle kugumbi lokupholisa piston nge-oscillation. Impilo yenkonzo ye-piston ingafinyelela amahora angama-25,000. I-cylinder liner enejakhethi yamanzi yenziwa nge-alloy cast iron. I-645 Series Diesel Engel yamukela i-Initized Full Indeltor ehlanganisa ipompo ephezulu yamafutha kanye nomjovo wamafutha kwiyunithi eyodwa. Njengezinjini ezingama-567 ze-Diesel Guelel, uchungechunge lwe-645 lusebenzisa inhlanganisela ye-mechanical superCharging kanye ne-turbocharging, ngokuxazulula inkinga enkulu yezinjini ezi-stroke disel. Lapho injini yedizili ingaphansi komthwalo ophansi futhi amandla okuqeda amandla aphansi kakhulu, i-crankshaft yenjini yedizili ishayela i-supercharger yemishini emagibeni. Lapho umthwalo wenjini yedizili uphakeme, ukuthathwa kudonsela i-turbine ukuze ujikeleze. Lo mklamo awukwazi ukwenza ngcono ukusheshisa kanye nekhwalithi yokuhlangana kwenjini yedizili emithanjeni ephansi, kepha futhi unikeze ukudlala okugcwele ezinhlelweni ze-turbocharging emithanjeni ephezulu.
