Mabasa eiyo mota yemafuta ekupa system ndeaya anotevera:
1. Ipa huwandu hunodiwa hwemafuta kune injini.
2. Iyo mafuta inopfuura nepakati pemafuta sefa kuti isefa tsvina.
3. Iyo mafuta inomanikidzwa nepombi yemafuta uye inogadziriswa kumanikidziro akakodzera kuburikidza nemafuta ekumanikidza regulator.
4. Inotumirwa kune pombi yekuparadzira mafuta kuburikidza nepombi yemafuta, uye injector yakaiswa pane injini uye pombi yekuparadzira mafuta.
Izvi zvinotevera ruzivo nezve iyo mafuta ekupa system:
1. Basa rekugadzirwa kwemafuta nderekupa mafuta pane imwe dzvinyiriro kune jekiseni, uye injector inosasa mafuta maererano nemirayiridzo yekombiyuta. Iyo mafuta ekufambisa sisitimu inosanganisira matangi emafuta, pombi yemafuta, mabhafa emafuta, mafuta ekumanikidza, mafirita emafuta, majekiseni, thermostat timing switch uye inotonhora yekutanga mavharuvhu (inotonhora yekutanga majekiseni) uye zvimwe zvikamu.
2. Nguva yekuvhura uye yekuvhara yeinjector inotungamirirwa nekombiyuta yejini. Kana jekiseni ravhurwa, rinogona kupfapfaidza mhute mukamuri yekupisa injini panguva yakakodzera uye yakawanda, uye inogona kupiswa chete mushure mekusanganiswa nemhepo muhurongwa hwekutora.
