Injector ndi gawo lofunikira kwambiri pa chipangizo chamagetsi chamagetsi chamafuta. Imawongolera jakisoni womaliza wamafuta. Ngati chinachake chalakwika, injini sigwira ntchito bwinobwino kapena kusiya ntchito yomweyo.

Ngati jekeseni imayikidwa pamalo oyambirira a carburetor ndikuphatikizidwa ndi throttle, mawonekedwewa amatchedwa single-point electronically controlled fuel injection. Ubwino wake ndi wotsika mtengo komanso kukonza kosavuta. Choyipa chake ndi chakuti mtunda wapakati pa jekeseni ndi silinda iliyonse ndi Kugawidwa kosagwirizana kwa mafuta kudzatsogolera kugawa mafuta osagwirizana, ndipo mafuta amamatira mosavuta pakhoma la chitoliro cholowetsa injini ikayamba.

Ngati jekeseni wayikidwa papaipi yolowera pa silinda iliyonse, mawonekedwewa amatchedwa multi-point electronically controlled fuel injection device, yomwe ndi mawonekedwe omwe amagwiritsidwa ntchito ndi injini zamakono zojambulira mafuta amagetsi. Ubwino wake ndikuti silinda iliyonse ili ndi jekeseni wake, ndipo jekeseni ili pafupi ndi valavu yowonongeka momwe zingathere, kupeŵa kuipa kwa jekeseni wamagetsi omwe amayendetsedwa ndi magetsi. Choyipa chake ndi kukwera mtengo komanso kukonza zovuta.

Pakalipano, injini zamagalimoto ambiri amagwiritsa ntchito jekeseni wamagetsi amtundu wambiri, ndipo magalimoto ochepa omwe amapeza ndalama amagwiritsa ntchito jekeseni wamagetsi amodzi. Ngati injini yakale ya carburetor isinthidwa kukhala jakisoni wamagetsi, jekeseni wamagetsi amodzi adzagwiritsidwa ntchito.

Nthawi zambiri, chipangizo chamagetsi choyendetsedwa ndi magetsi pamagalimoto chimakhala ndi magawo atatu: gawo lopangira mafuta, gawo loperekera mpweya ndi gawo lowongolera. Gawo loperekera mafuta limakhala ndi thanki yamafuta, pampu yamafuta, fyuluta yamafuta, chowongolera kupanikizika ndi jekeseni wamafuta. Pampu ya petulo imakoka mafuta mu thanki yamafuta ndikusefa zonyansa kudzera muzosefera zamafuta. The pressure regulator pressurize petroli kuti ifike pamwamba kuposa Kuthamanga koipa muzowonjezereka kumatumizidwa ku majekeseni a silinda iliyonse kupyolera mupaipi yamafuta. Injector ndi yofanana ndi chosinthira, ndipo chigawo chomwe chimayang'anira kusinthako ndi ECU (electronic control unit).
