Likopo

Ka lebaka la ho hanyetsa mocheso le ho tjheseletsa ha yona, tshepe e sa ruseng ya 321 e sebediswa haholo ho:

Likarolo tsa Enjene ea Lifofane le Jet (litsamaiso tsa ho ntša mosi, likamore tsa ho chesa)

Lisebelisoa tsa Lik'hemik'hale le Petrochemical (li-heat exchange, lijana tsa khatello)

Liphaephe le Liboiler tsa Mocheso o Phahameng (botsitso ba mocheso)

Mekhoa ea ho ntša mosi oa likoloi (li-manifold, li-catalytic converter)

Lisebelisoa tsa ho Sebetsa Lijo le tsa Meriana (moo ho hlokahalang ho tjheseletsa)
