Iyo mafuta ekugovera sisitimu chikamu chakakosha cheinjini yemotokari, iyo ine basa rekupa injini nemusanganiswa unopisa. Iyo sisitimu ine zvikamu zvakawanda, zvinosanganisira tangi yemafuta, pombi yemafuta, buffer yemafuta, mafuta ekumanikidza regulator, sefa yemafuta, jekiseni, uye inotonhora yekutanga valve (inotonhora yekutanga injector). Basa guru regadziriro yekugovera mafuta ndeyekuchengetedza uye kusefa mafuta uye kuishandura kuita musanganiswa unopisa kuti usangane nezvinodiwa zvejini. Nzira yekugovera yemafuta akasiyana ichave yakasiyana. Semuenzaniso, iyo peturu yekugovera sisitimu inogadzirira imwe chiyero uye kusangana kwegasi rakasanganiswa zvinoenderana nezvinodiwa zveinjini. Mukuwedzera, iyo mafuta ekugovera sisitimu inowanzotora nzira mbiri dzemaitiro, imwe ine tekinoroji yepombi yekudzoka uye imwe isina tekinoroji yepombi yekudzoka. Iyo mafuta ekupa system inoita basa rakakosha mukushanda kwakajairwa kweinjini yemotokari.
Nheyo yekushanda yegadziriro yemafuta ndeyekubvisa mafuta kubva mutangi yemafuta uye kuiendesa kukamuri yekupisa injini. Mukuita uku, iyo mafuta ekupa system inoda kuchengetedza yakagadzikana kuyerera uye kudzvanywa kwemafuta kuti ive nechokwadi chekushanda kwakajairika kweinjini. Iyo pombi yemafuta ndiyo yakakosha chikamu cheiyo mafuta ekupa system, iyo ine basa rekubvisa mafuta kubva mutangi remafuta uye kuendesa kune injini. Iyo mafuta buffer inoshandiswa kugadzirisa kuyerera uye kudzvanywa kwemafuta kuti ive nechokwadi chekugadzikana kweiyo mafuta ekupa system. Iyo sefa yemafuta inoshandiswa kusefa kusvibiswa uye kusvibiswa mumafuta kudzivirira injini kubva mukukuvadzwa. Iyo jekiseni inopfapfaidza mafuta mukamuri yekupisa injini kuti iwane chizvarwa chemusanganiswa unopisa. Iyo inotonhora yekutanga valve (inotonhora yekutanga injector) inoshandiswa kupa mamwe mafuta kana injini yatanga kutonhora kuve nechokwadi kuti injini inogona kutanga zvakanaka.
Magadzirirwo uye maitiro ekushanda kwemafuta ekupa system anosiyana zvichienderana nemafuta. Semuenzaniso, iyo peturu yekugovera sisitimu inowanzo tora maviri ezvimiro modhi, imwe ine yekudzoka pombi tekinoroji uye imwe isina kudzoka pombi tekinoroji. Iyo mafuta ekugovera sisitimu ine kudzoka pombi tekinoroji inodzosera yakawandisa mafuta kune tangi yemafuta kana injini yamira kumhanya kuchengetedza mafuta uye kuchengetedza zvakatipoteredza. Iyo tekinoroji isina pombi yekudzoka haina basa iri, asi inogona kushandisa mafuta zvakanyanya uye inovandudza kushandiswa kwemafuta. Pasinei nechimiro chechimiro, iyo mafuta ekugovera sisitimu inofanirwa kuchengetedza yakagadzikana yekushanda mamiriro kuti ive nechokwadi chekushanda kwakajairika kweinjini.
