1. Imoto ibuthakathaka ekugijimeni futhi imoto ayikwazi ukugijima. Kungcono uma ijubane lidlula 2500 rpm;
2. Imoto izosetshenziswa kakhulu uphethiloli, ikhiphe umoya omningi, futhi kuphume intuthu emnyama engathandeki epayipini le-exhaust;
3. Ngemva kokuba isibani esinephutha lenjini sithole ukuthi inzwa inephutha, izokhanyisa isibani esinephutha ukukhumbuza umnikazi ukuthi ahlole futhi anakekele;
4. Ijubane lokudlalisa imoto alizinzile futhi ukudlidliza kubi kakhulu, kufana nokuhluleka kwemoto engenasilinda;
5. Ngesikhathi senqubo yokuqalisa, i-crankshaft izohlehliswa, futhi kuzoba nesenzakalo esishisayo ekwakhiweni okuhlukahlukene. I-camshaft iyingxenye yenjini ye-piston elawula ukuvulwa nokuvalwa kwe-valve.
Nakuba i-camshaft izungeza engxenyeni yejubane le-crankshaft enjinini enama-stroke amane, imvamisa isephezulu kakhulu futhi idinga i-torque eningi.
