● Kubaluleke kakhulu ekusebenzeni nasekukhishweni kwezinjini zikadizili.
● Kuyasiza empilweni yenjini.
● Inokukhiqiza okunembayo nokuvumelana nezimo okuphezulu.
Umbhobho uvamise ukuba yipayipi noma ishubhu lendawo ehlukene yezingxenye eziphambanayo, futhi ungasetshenziswa ukuqondisa noma ukuguqula ukugeleza koketshezi (uketshezi noma igesi).Ama-nozzles asetshenziswa kaningi ukulawula izinga lokugeleza, isivinini, isiqondiso, ubukhulu, ukwakheka, kanye/noma ingcindezi yomfudlana ophuma kuwo.
Umbhobho wokujova isifutho esihle lapho uphethiloli ujova khona enjinini.Ingaphezulu lombhobho wokujova linezimbobo eziningi zokuletha isifutho sikaphethiloli wedizili kusilinda.
Idizayini yombhobho wokujova udizili ibalulekile ekusebenzeni nasekukhishweni kwezinjini zesimanje zikadizili.Eminye yemingcele ebalulekile yomklamo wombhobho womjovo ihlanganisa imininingwane yesihlalo somjovo, isaka lomjovo kanye nosayizi wembobo yombhobho kanye nokuma.Lezi zici azithinti nje kuphela izici zokusha zenjini kadizili, zingaphinde zibe nomthelela ekuzinzeni kwezisi ezikhishwayo kanye nokusebenza ngesikhathi sempilo yenjini kanye nokuqina komshini womjovo.
Imibhobho yomjovo isebenzisana namaPiston ku-Combustion Chambers.Lapho i-Piston idonselwa kude ne-sparkplug, umlomo womjovo ufafaza ingxube kaphethiloli nomoya eGumbini Lokuvutha.
Njengenye yezingxenye ezibalulekile zenjini, umsebenzi we-nozzle uzothinta kakhulu ukusebenza kwenjini.Imibhobho kaphethiloli evalekile ingaphazamisa kakhulu ukusebenza kwemoto.Isizathu sokuvaleka kungenxa yokubekeka kwekhabhoni enjinini ku-nozzle noma ngenxa yokungcola kuphethiloli okuvimbe umzila wombhobho.Ngakho-ke, umlomo wombhobho kufanele uhlanzwe ngokucophelela futhi uhlolwe njalo ukuze kuqinisekiswe ukuthi usebenza kahle.
