Chitoliro chachitsulo chosasunthika cha 20G ndi mtundu wodziwika bwino wa chitoliro chachitsulo chosasunthika. "20G" m'dzina lake ikuyimira zinthu za chitoliro chachitsulo, ndipo "chosasunthika" chikuyimira njira yopangira. Chitsulochi nthawi zambiri chimapangidwa ndi chitsulo cha kaboni, chitsulo cha alloy, ndi zina zotero, ndipo chili ndi mphamvu zabwino zamakanika komanso kusinthasintha. Makhalidwe akuluakulu a chitoliro chachitsulo chosasunthika cha 20G ndi kukana kutentha kwambiri, kukana dzimbiri, mphamvu yayikulu yokakamiza, ndi zina zotero. Chifukwa chake, chimagwiritsidwa ntchito kwambiri mu mafuta, gasi wachilengedwe, makampani opanga mankhwala, mphamvu zamagetsi, zomangamanga ndi zina.
