Umjovo uyingxenye ebaluleke kakhulu kudivayisi yomjovo we-elekthronikhi kaphethiloli. Ilawula umjovo wokugcina kaphethiloli. Uma kukhona okungahambi kahle, injini ngeke isebenze ngokujwayelekile noma iyeke ukusebenza ngokushesha.

Uma i-injector ifakwe endaweni yokuqala ye-carburetor futhi ihlanganiswe ne-throttle, leli fomu libizwa ngokuthi i-single-point controlled fuel injection. Inzuzo yayo yizindleko eziphansi kanye nokugcinwa okulula. Okubi ukuthi ibanga eliphakathi kwendawo yomjovo nesilinda ngalinye liwukuthi Ukusatshalaliswa okungalingani kukaphethiloli kuzoholela ekusabalaliseni uphethiloli okungalingani, futhi uphethiloli uzonamathela kalula odongeni lwepayipi lokungena lapho injini ebandayo iqaliswa.

Uma i-injector ifakwe epayipini lokungena lesilinda ngalinye, leli fomu libizwa ngokuthi i-multi-point electronic controlally controlled fuel injection, okuyifomu elisetshenziswa iningi lamanje le-electronic injini yokujova kaphethiloli. Inzuzo yayo ukuthi i-cylinder ngayinye ine-injector yayo, futhi i-injector iseduze ne-valve yokungenisa ngangokunokwenzeka, igwema ukungalungi kwe-single-point elawulwa nge-electronic fuel injection. Ububi bezindleko eziphezulu kanye nokugcinwa okuyinkimbinkimbi.

Njengamanje, izinjini eziningi zezimoto zisebenzisa umjovo we-elekthronikhi onamaphuzu amaningi, futhi inombolo encane yezimoto ezongayo zisebenzisa umjovo we-elekhthronikhi onephuzu elilodwa. Uma injini ye-carburetor endala iguqulwa ibe umjovo we-elekthronikhi, umjovo we-electronic onephuzu elilodwa uzosetshenziswa.

Ngokuvamile, idivayisi yomjovo kaphethiloli elawulwa nge-elekthronikhi ezimotweni inezingxenye ezintathu: ingxenye yokuphakelwa kukaphethiloli, ingxenye yokuphakelwa komoya kanye nengxenye yokulawula. Ingxenye yokunikeza uphethiloli iqukethe ithangi likaphethiloli, ipompo likaphethiloli, isihlungi sikaphethiloli, isilawuli sokucindezela umfutho kanye nesijova sikaphethiloli. Iphampu kaphethiloli idonsa uphethiloli ethangini likaphethiloli futhi ihlunge ukungcola ngesihlungi sikaphethiloli. I-pressure regulator icindezela uphethiloli ingcindezi ephakeme kune-Ingcindezi engalungile ku-manifold yokungenisa ithunyelwa kuma-injection yesilinda ngayinye ngepayipi likawoyela. Umjovo ulingana neswishi, futhi ingxenye elawula iswishi i-ECU (iyunithi yokulawula ngogesi).
