Kuyiphutha elivamile ukuthi i-valve yenaliti ye-fuel injector yenjini ye-diesel "ishiswe" ngesikhathi sokusetshenziswa. Uma injini ye-diesel isebenza, isikulufu sokulungisa umfutho esikujovini kaphethiloli siyaqiniswa noma siyaxegiswa, kodwa injini yedizili ayinalo ushintsho. Ngaphezu kwalokho, ngenxa yezikhundla ezahlukene ze-valve yenaliti ye-fuel injector lapho "ishisiwe", ukusebenza kwenjini ye-diesel akufani ncamashi lapho isebenza. Lapho i-valve yenaliti "ishisiwe" endaweni evulekile, kuzoba nomsindo othile ozwakalayo wensimbi ongqongqozayo kusilinda. Izinga lokushisa lomshini wokujova uphethiloli, ipayipi likawoyela elinomfutho ophezulu kanye nepayipi lokukhipha injini liphezulu kunamanye amasilinda. Ngesikhathi sokuhlolwa kwe-oil cut-off, umsindo ongqongqozayo kanye nentuthu emhlophe ephuma ekuphumeni kuzonyamalala ngemva kokunqunywa kwamafutha. Khipha i-valve yesijojo sikaphethiloli "eshisiwe" engxenyeni exegisiwe yepayipi likaphethiloli elinomfutho ophezulu ukuze ubuke ingxenye yalo yomhlahlandlela. Kuyabonakala ukuthi iningi lendawo yokuqala ekhanyayo selishisiwe. Igesi eshisayo ekusilinda igeleza ibuyele endaweni yomjovo, ibangele ukuthi idizili engaphakathi komjovo wabole futhi i-carbonize yakhe amadiphozithi ekhabhoni, okuholela ekulimaleni kokuvalwa kwendawo yokuhlala. Umjovo kaphethiloli ushiselwa ngokweqile, okwenza ukunyakaza kwevalvu yenaliti kuvimbe futhi i-atomization yedizili iba buthakathaka, futhi ekugcineni ivalvu yenaliti yomjovo kaphethiloli iyashiswa ize ife.
