Kuphulika kwake kungayambitse kugunda kwa pistoni ndi ma valve, zomwe zinawononga kwambiri injini. Kodi kuipa kwa injini iyi ndi chiyani? Choyambirira:

• nagarobrazovanie;
• zambiri zamtengo wapatali;
• mtengo wapamwamba wa mafuta.

Wopangayo amalimbikitsanso kuti musapitirire nthawi yosinthira mafuta pamakilomita 10. Chifukwa? Settlement scale. Kuphatikiza apo, mbali zake sizikhala zotsika mtengo nthawi zonse mukagula m'dziko lathu. Zachidziwikire, zitha kutumizidwa kuchokera ku US, koma zimatenga nthawi.
