Injiniyo ili ndi mawonekedwe olimba okhala ndi chipika chachitsulo cholemera kwambiri, crankshaft yachitsulo yonyezimira komanso ndodo zolumikizira mwamphamvu kwambiri. Injiniyo ilinso ndi chitetezo cha injini yomwe imayang'anira magawo ofunikira a injini ndikupereka chenjezo kapena kuzimitsa injini ngati kuli kofunikira. Mwachidule, Cummins QSM 12 Tier IV ndi injini ya dizilo yamphamvu komanso yothandiza yomwe imagwirizana ndi zomwe zaposachedwa kwambiri. Ukadaulo wake wapamwamba komanso kapangidwe kake kolimba kamapangitsa kuti ikhale yabwino pamapulogalamu omwe amafunikira mphamvu yodalirika komanso yosasinthika.
