Mwachidule
Chitsulo chachitsulo chimagwiritsidwa ntchito popanga mapaipi akulu akulu otchingidwa omwe amanyamula mafuta ndi gasi wachilengedwe, omwe amatchedwanso kuti mbale yachitsulo. Tsopano anthu ochulukirachulukira padziko lapansi akuyang'ana kwambiri kuteteza chilengedwe chathu, gasi watsopano wamagetsi achilengedwe amagwiritsidwa ntchito kwambiri kudzera m'mapaipi. Zitsulo zapaipi izi zinali ndi kuthekera kolimbana ndi kuthamanga kwambiri, dzimbiri mumlengalenga komanso malo otsika kutentha. API X120 yoperekedwa kuchokera kwa ife inali ndi zida zamakina apamwamba kuposa mlingo wapadziko lonse lapansi.
