Ngokombono wezimpawu zokuhlala eziguquguqukayo, ngemva kocwaningo, isibalo sokunyakaza esiguquguqukayo senqubo yokuphakamisa inaliti inaliti kwakhiwa, futhi kwaqhathaniswa nesibalo sebhalansi emile. Ngochungechunge locwaningo lokuhlola nokuhlaziywa kwethiyori, iziphetho ezifinyelelwe zimi kanje:, uma kuqhathaniswa nesimo esimile, ingcindezi yokuvula eguquguqukayo yevalve yenaliti iphakeme kakhulu, kodwa ingcindezi yokuvala enamandla iphansi ngokuqhathaniswa, ehlobene eduze izimo zokusebenza injini. Ngenxa yokuthi i-valve yenaliti inezici zokuhlala eziguqukayo, iphinde ikhulise ububanzi bokudonsa uwoyela esigabeni sakamuva somjovo, ngaleyo ndlela yehlise izinga lokufafaza, futhi ifinyeze impilo yombhobho kawoyela, ibeke usongo kunkomba yokukhishwa. . Enqubweni yokufaka i-valve yenaliti yokuhlanganisa i-injector, ngenxa yesimo esibucayi kakhulu sokusebenza, indawo ye-cone yokuvala uphawu ijwayele ukuguga. Isizathu singenxa yokungcola okukhiqizwa kuphethiloli namandla okushayisana okubangwa lapho i-valve yenaliti ihlezi. Ngemuva kokuguga, kuzodala ukuwohloka kwendawo yekhoni yokuvala, kukhuphule ukuhwaqeka kobuso, kunciphise kakhulu umphumela wokuvala, futhi yehluleke ukukhiqiza umphumela omuhle wokufutha. Ngaphezu kwalokho, ukuconsa kukawoyela kuzokwenzeka, futhi uwoyela wedizili awukwazi ukushiswa ngokuphelele. Ekamelweni elivuthayo, izimbobo zomjovo kanye nezingxenye ezibandayo ezisebenzayo, amadiphozithi ekhabhoni amaningi akhiqizwa, okuholela ekuvinjweni kwezimbobo zomjovo. Ekugcineni, amandla enjini ye-diesel ancipha kakhulu, okuholele ekusetshenzisweni kukaphethiloli okuqondile.
