Zomwe zimatchedwa jekeseni wamagetsi amagetsi ndi kuyeza kuchuluka kwa mpweya womwe umayamwa mu injini, ndiyeno kupereka mlingo woyenera wa mafuta ku injini ndi jekeseni wothamanga kwambiri.Njira yoyendetsera makompyuta poyang'anira chiŵerengero chosakanikirana cha mpweya ndi petulo imatchedwa jekeseni wamagetsi oyendetsedwa ndi magetsi.Njira yoperekera mafuta iyi ndi yosiyana ndi yachikhalidwe cha carburetor.The carburetor amadalira mphamvu zoipa kwaiye kwa mpweya ukuyenda mu kabureta akudikirira chubu kuyamwa mafuta mu chipinda zoyandama pakhosi ndi kupanga chisakanizo choyaka ndi mpweya otaya nkhungu.

Lamulirani zomwe zili mkati ndi ntchito zamagetsi amagetsi ojambulira mafuta (FE1):
1. Kuwongolera kuchuluka kwa jekeseni wamafuta ECU kumatenga liwiro la injini ndi chizindikiro cha katundu ngati chizindikiro chachikulu chowongolera kuti mudziwe kuchuluka kwa jakisoni wamafuta (nthawi yotsegulira valavu ya jekeseni ya solenoid), ndikuwongolera molingana ndi zizindikiro zina zofunika, ndi potsiriza dziwani kuchuluka kwa jekeseni wamafuta.
2. ECU yolamulira nthawi ya jekeseni imayendetsa nthawi ya jekeseni pa nthawi yoyenera malinga ndi chizindikiro cha crankshaft phase sensor ndi kuwombera kwazitsulo ziwiri.
3. Pamene decelerating ndi kuchepetsa mafuta odulidwa kulamulira njinga yamoto yoyendetsa galimoto, pamene dalaivala mwamsanga amatulutsa phokoso, ECU idzadula dera loyendetsa jekeseni wa mafuta ndikuyimitsa jekeseni wa mafuta kuti muchepetse mpweya wotulutsa mpweya ndi kugwiritsira ntchito mafuta panthawi ya deceleration.Injini ikamathamanga ndipo liwiro la injini limaposa liwiro lotetezeka, ECU idzadula dera lowongolera jekeseni wamafuta pa liwiro lovuta ndikuyimitsa jekeseni wamafuta kuti ateteze injini ku liwiro komanso kuwononga injini.
4. Kuwongolera pampu yamafuta Pamene chowotcha choyatsira chiyatsidwa, ECU idzawongolera pampu yamafuta kuti igwire ntchito kwa masekondi 2-3 kuti ikhazikitse kuthamanga kwamafuta kofunikira.Panthawi imeneyi, ngati injini sangathe anayambitsa, ECU adzadula ulamuliro dera mpope mafuta ndi mpope mafuta kusiya ntchito.ECU imayang'anira pampu yamafuta kuti ikhalebe yogwira ntchito nthawi zonse injini ikayamba ndikuyenda.

Njira ya jakisoni wa Airway.Zomwe zimapangidwira njira iyi ndikuti injini yoyambirira ndi yaying'ono, mtengo wopangira ndi wotsika, ndipo mphamvu yogwira ntchito imakhala yabwino kwambiri poyerekeza ndi injini wamba ya carburetor.

Dongosolo la jakisoni lamafuta loyendetsedwa ndimagetsi lili ndi zabwino zotsatirazi poyerekeza ndi mtundu wa carburetor woperekera ndi kusakanikirana:

1. Kukhazikitsidwa kwaukadaulo wowongolera pakompyuta kumachepetsa kuwonongeka kwa utsi ndikugwiritsa ntchito mafuta a injini, zomwe zimatha kukwaniritsa zofunikira za malamulo okhwima otulutsa mpweya;
2. Chigawo choyang'anira zamagetsi (ECU) chimayankha mwamsanga kusintha kwa valve throttle, yomwe imapangitsa kuti ntchito yogwira ntchito ikhale yofulumira komanso yofulumira ya injini, ndipo imatha kusunga zizindikiro zabwino zogwira ntchito;Kulola injini kutengera chiŵerengero chapamwamba cha kuponderezana kumapangitsa kuti injiniyo ikhale yotentha komanso imachepetsa kugogoda kwa injini;
3. Dongosolo la EFI lili ndi kusinthika kwamphamvu.Kwa injini zamitundu yosiyanasiyana, muyenera kusintha "pulse sipekitiramu" mu ECU chip, pomwe mpope womwewo wamafuta, nozzles, ECU, etc. mndandanda wazinthu;
4. Kusintha kwa magwiridwe antchito a injini.

Kusiyanitsa pakati pa ziwirizi ndikuti kuyankha kwa carburetor throttle ndi koyipa, kuwongolera kwamafuta kumakhala koyipa, kugwiritsa ntchito mafuta kumakhala kwakukulu, mphamvu ya atomization yamafuta ndiyosauka, kuzizira koyambira kumakhala koyipa, kapangidwe kake ndizovuta, komanso kulemera kwake ndikwambiri. .Injini ya carburetor yamagalimoto idasiya kupanga.Injector yamagetsi yamagetsi imakhala ndi kuwongolera kokwanira kwamafuta, kuyankha mwachangu, mphamvu yabwino yamafuta atomu, mawonekedwe ovuta, voliyumu yaying'ono, kulemera kopepuka, kuchuluka kwamafuta otsika kwambiri kuposa carburetor, komanso kuzizira koyambira.
