Isitofu licandelo elibaluleke kakhulu kwisixhobo sokutofa nge-elektroniki sepetroli. Ilawula inaliti yokugqibela yesibaso. Ukuba kukho into engahambi kakuhle, injini ayiyi kusebenza ngokuqhelekileyo okanye iyeke ukusebenza ngoko nangoko.

Ukuba i-injector ifakwe kwindawo yokuqala ye-carburetor kwaye idibaniswe ne-throttle, le fomu ibizwa ngokuba yi-single-point controlled fuel injection. Inzuzo yayo yindleko ephantsi kunye nokugcinwa okulula. Ukungalungi kukuba umgama phakathi kwendawo yokutofa kunye ne-cylinder nganye Ukusasazwa ngokungalingani kwamafutha kuya kukhokelela ekusasazeni amafutha angalingani, kwaye i-fuel iya kubambelela ngokulula eludongeni lombhobho wokuthatha xa injini ebandayo iqaliswa.

Ukuba i-injector ifakwe kumbhobho wokungenisa we-cylinder nganye, le fomu ibizwa ngokuba yi-multi-point electronic controlled fuel injection device, eyifomu esetyenziswa ngobuninzi bee-injini ze-elektroniki ze-petroli. Inzuzo yayo kukuba i-cylinder nganye ine-injector yayo, kwaye i-injector isondele kwi-valve yokungena ngokusemandleni, ukuphepha ukungahambi kakuhle kwe-injection ye-fuel elawulwa nge-elektroniki. Ukungalungi ziindleko eziphezulu kunye nolondolozo olunzima.

Okwangoku, uninzi lweenjini zemoto zisebenzisa inaliti ye-elektroniki ene-multi-point, kwaye inani elincinci leemoto ezinoqoqosho zisebenzisa inaliti ye-elektroniki enenqaku elinye. Ukuba i-injini ye-carburetor endala iguqulelwa kwisitofu sombane, inaliti ye-electronic point enye iya kusetyenziswa.

Ngokubanzi, isixhobo sokutofa kwepetroli esilawulwa ngombane ezimotweni sinamacandelo amathathu: indawo yokubonelela ngamafutha, indawo yokubonelela ngomoya kunye nenxalenye yolawulo. Inxalenye yonikezelo lwamafutha iquka itanki yamafutha, impompo yepetroli, isihluzo sepetroli, isilawuli soxinzelelo kunye nesitofu sepetroli. Ipompo yepetroli itsala i-petroli kwitanki yamafutha kwaye ihluze ukungcola ngesihluzo sepetroli. Umlawuli woxinzelelo ucinezela i-petroli kuxinzelelo oluphezulu kunokuba Uxinzelelo olubi kwi-manifold yokungenisa luthunyelwa kwii-injection ze-cylinder nganye ngombhobho weoli. I-injector ilingana nokutshintsha, kwaye icandelo elilawula ukutshintshela yi-ECU (iyunithi yokulawula i-electronic).
