Lokhu okubizwa ngokuthi umjovo kaphethiloli we-elekthronikhi uwukukala inani lomoya ofakwe enjinini, bese unikeza inani elifanele likaphethiloli enjinini ngomjovo wengcindezi ephezulu.Inqubo yokulawula ikhompuyutha yokulawula isilinganiso sengxube somoya nophethiloli ibizwa ngokuthi umjovo kaphethiloli olawulwa nge-elekthronikhi.Le ndlela yokuhlinzeka uwoyela ihlukile ku-carburetor yendabuko ngokomthetho.I-carburetor incike ekucindezelweni okungekuhle okukhiqizwa umoya ogeleza ngeshubhu lokulinda le-carburetor ukumunca uphethiloli osegumbini lokuntanta emqaleni futhi yakhe ingxube evuthayo nenkungu yokugeleza komoya.

Lawula okuqukethwe kanye nemisebenzi ye-electronic fuel injection system (FE1):
1. I-ECU yokulawula inani lomjovo kaphethiloli ithatha isivinini senjini kanye nesiginali yokulayisha njengesiginali yokulawula eyinhloko ukuze inqume inani lomjovo kaphethiloli eliyisisekelo (isikhathi sokuvulwa kwe-valve ye-solenoid yomjovo kaphethiloli), futhi ilungise ngokuvumelana nezinye izimpawu zokufaka ezifanele, futhi ekugcineni thola inani eliphelele lomjovo kaphethiloli.
2. I-ECU yokulawula isikhathi somjovo ilawula isikhathi somjovo ngesikhathi esifanele ngokuvumelana nesignali yenzwa yesigaba se-crankshaft kanye nokulandelana kokudubula kwamasilinda amabili.
3. Lapho wehlisa isivinini futhi unciphisa isithuthuthu sokulawula ukunqanyulwa kukaphethiloli ukushayela, lapho umshayeli ededela i-throttle ngokushesha, i-ECU izonqamula umjikelezo wokulawula umjovo kaphethiloli futhi imise umjovo kaphethiloli ukuze kuncishiswe ukukhishwa kwe-exhaust kanye nokusetshenziswa kukaphethiloli ngesikhathi sokuncipha.Uma injini ishesha futhi isivinini senjini sidlula isivinini esiphephile, i-ECU izonqamula umjikelezo wokulawula umjovo kaphethiloli ngesivinini esibucayi futhi imise umjovo kaphethiloli ukuvimbela injini ukuba idlule isivinini futhi ilimaze injini.
4. Ukulawula iphampu yesibaseli Lapho inkinobho yokuthungela ivuliwe, i-ECU izolawula iphampu yamafutha ukuze isebenze imizuzwana engu-2-3 ukuze kutholwe ingcindezi kawoyela edingekayo.Ngalesi sikhathi, uma injini ingakwazi ukuqaliswa, i-ECU izonqamula umjikelezo wokulawula wepompo likaphethiloli futhi iphampu yamafutha izoyeka ukusebenza.I-ECU ilawula iphampu kaphethiloli ukuze igcine ukusebenza okuvamile ngesikhathi injini iqala futhi isebenza.

Imodi yomjovo womoya.Izici ezijwayelekile zale ndlela ukuthi injini yokuqala incane, izindleko zokukhiqiza ziphansi, futhi ukusebenza kahle kwamandla okusebenza kuthuthukiswa kakhulu uma kuqhathaniswa nenjini evamile ye-carburetor.

Isistimu yomjovo kaphethiloli elawulwa nge-elekthronikhi inezinzuzo ezilandelayo uma iqhathaniswa nohlobo lwe-carburetor lokunikezela kanye nemodi yokuxuba:

1. Ukwamukelwa kobuchwepheshe bokulawula i-elekthronikhi kunciphisa ukungcoliswa komoya kanye nokusetshenziswa kukaphethiloli kwenjini, okungahlangabezana nezidingo zemithetho eqinile yokukhipha umoya;
2. Iyunithi yokulawula i-elekthronikhi (ECU) iphendula ngokushesha ekushintsheni kwe-valve ye-throttle, ethuthukisa ukusebenza kokusingatha kanye nokusebenza kokusheshisa kwenjini, futhi ingagcina izinkomba zokusebenza ezishukumisayo ezinhle;Ukuvumela injini ukuba yamukele isilinganiso esiphezulu sokuminyanisa kuthuthukisa ukusebenza kahle kokushisa kwenjini futhi kunciphisa ukuthambekela kokungqongqoza kwenjini;
3. Uhlelo lwe-EFI lunokuvumelana nezimo okuqinile.Ezinjini zamamodeli ahlukene, kuphela "i-pulse spectrum" ku-chip ye-ECU idinga ukushintshwa, kuyilapho iphampu yamafutha efanayo, umlomo wombhobho, i-ECU, njll. uchungechunge lwemikhiqizo;
4. Ukulungiswa kokusebenza kwenjini okulula.

Umehluko phakathi kwalokhu okubili ukuthi impendulo ye-carburetor throttle ayilungile, ukulawulwa kokunikezwa kukaphethiloli kubi, ukusetshenziswa kukaphethiloli kuphezulu, umphumela we-atomization kaphethiloli umpofu, isiqalo esibandayo sibi, isakhiwo siyinkimbinkimbi, futhi isisindo sikhulu. .Injini ye-carburetor yemoto kade yaphelelwa ukukhiqizwa.Umjovo kaphethiloli we-elekthronikhi unokulawula okunembile kokunikezwa kukaphethiloli, ukusabela okusheshayo, umphumela omuhle we-atomization kaphethiloli, isakhiwo esiyinkimbinkimbi, ivolumu encane, isisindo esincane, izinga lokusetshenziswa kukaphethiloli elingaphansi kakhulu kune-carburetor, kanye nomphumela omuhle wokuqala obandayo.
