Izitofu zamafutha zidlala indima ebalulekileyo kwiinjini zedizili. Ikakhulu inoxanduva lokutofa amafutha kwigumbi lokutsha le-injini ngoxinzelelo oluchanekileyo, ixesha kunye ne-atomization. Ngolawulo lwenaliti yesibaso olufanelekileyo, kuqinisekiswa ukuba isibaso sinokuxutywa ngokupheleleyo nomoya, ngaloo ndlela kuzuze ukutsha okusebenzayo.

I-injector ye-fuel ingakwazi ukulungelelanisa ngokuchanekileyo isixa kunye nexesha lokujova kwe-fuel ngokwemiqathango eyahlukeneyo yokusebenza kwe-injini, njengesantya, umthwalo, njl. ukwandisa ubungakanani benaliti yamafutha kwimithwalo ephezulu ukunika amandla aneleyo; ukunciphisa ubungakanani benaliti yamafutha kwimithwalo ephantsi ukugcina amafutha. Ukusebenza kakuhle kwesitofu se-fuel inceda ukuphucula amandla e-injini, uqoqosho kunye nokusebenza kokukhutshwa. Inokwenza ukuba ukutsha kugqibelele, kunciphise ukukhutshwa kwezinto ezingcolisayo okubangelwa kukutsha okungaphelelanga, kwaye kwakhona kuvumele injini ukuba ikhuphe amandla anamandla ngakumbi. Ukongeza, ulawulo oluchanekileyo lwee-injection zamafutha lunokunciphisa ukusetyenziswa kwamafutha kunye nokuphucula ukusetyenziswa kwamafutha. Iindidi ezahlukeneyo kunye neenkcukacha zee-injection zilungelelanisa ukucwangciswa kweenjini ezahlukeneyo kunye neemfuno zesicelo, kwaye kunye ziqinisekisa ukusebenza okuzinzileyo nokuthembekileyo kwe-injini.

Ukusilela okuqhelekileyo kwesitofu sesibaso kubandakanya oku kulandelayo:
I-atomization engafanelekanga: Ngenxa yoko, i-fuel ayinakuchithwa kakuhle, ichaphazela ukusebenza kakuhle kokutsha, okunokubangela ukuba amandla e-injini ehle, ukusetyenziswa kwepetroli kwanda, kunye nokukhutshwa kokukhutshwa komlilo.
Ukuthontsiza: I-fuel ithontsiza ngokuqhubekayo kwi-injector, nto leyo eya kubangela ukuba umxube utyebe kakhulu, kubangele ukuba injini ingasebenzi kakuhle, ishukume, kwaye iqale nzima.
Ukuvala: Ukungcola kunye nezinye izinto zinokuvala imingxuma yokutofa okanye amajelo angaphakathi e-injector, okukhokelela ekunciphiseni inaliti yamafutha okanye kungabikho naliti yamafutha, okubangela iingxaki ezifana nokungonelanga kwamandla e-injini kunye nokunqongophala kwe-cylinder.
Uxinzelelo lwenaliti ye-fuel engaqhelekanga: Uxinzelelo oluphezulu kakhulu okanye oluphantsi kakhulu luya kuchaphazela isiphumo sokutofa kwamafutha, okukhokelela ekutshisweni okunganeleyo okanye ukusebenza kakubi kwamandla.
Ukungaphumeleli kwekhoyili ye-Solenoid: njenge-coil short circuit, i-circuit evulekile, njl., iya kubangela ukuba i-injector ingaphumeleli ukusebenza kakuhle.
Inaliti yevalve ebambekayo: Inokuthintela isitofu se-fuel ekuvuleni okanye ekuvaleni ngokuqhelekileyo, nto leyo echaphazela inkqubela yesiqhelo yenaliti yamafutha.
