Electronic mafuta injector ntchito mfundo

Injector yamagetsi yamagetsi imadziwikanso kuti EUI, imagwira ntchito bwanji?Mfundo yake yogwira ntchito ndi chabe kuti chizindikiro chamagetsi choperekedwa ndi ECM chimatumizidwa ku valve solenoid, yomwe imayang'anira kutsegula ndi kutseka kwa valve ya singano, motero imasamutsira mafuta enaake mkati mwa jekeseni.Kuchuluka ndi nthawi ya jakisoni zimayendetsedwa ndendende ndi ECM algorithm ndi MAP.Kuchuluka kwa jekeseni wamafuta kumatsimikiziridwa ndi nthawi ya jakisoni komanso liwiro la jekeseni wa plunger, ndipo zimayenderana.Nthawi yomwe valve solenoid imayendetsedwa ndi chiyambi cha jekeseni wa mafuta, ndipo kutaya mphamvu ndiko kutha kwa jekeseni wa mafuta.Nazi njira zinayi zogwirira ntchito za jekeseni.

 Sitiroko yoyamwa

Njira yamafuta imalumikizidwa ndi mutu wa silinda ya injini kuti ipereke mafuta kudzera pamutu wa silinda kupita kwa ma injectors, kotero mapangidwe a mzere wamafuta ayenera kuwonetsetsa kuti kutentha kwamafuta kumakhala kofanana pakati pa majekeseni.Mafuta atatha kulowa mu jekeseni, mafuta amasungidwa ndi kukhazikika m'chipinda chamkati, pamene madzi ndi nthunzi mumafuta amachitika.Pa sitiroko imeneyi, jekeseni plunger imakwera ndipo mafuta amathira mu jekeseni, ndikudzaza jekeseni wa jekeseni.

Jekeseni sitiroko

Injector plunger ikayamba kutsika, mafuta omwe ali pansi pa plunger amachoka mu jekeseni ndikubwerera kumalo ozungulira mafuta.Ngati ECM sichiwonetsa valavu ya solenoid, ndiye kuti zonse zidzabwerera ku dera la mafuta.Pamene ECM ikupereka chizindikiro ku valve solenoid, valve ya singano yoyendetsedwa ndi solenoid valve imatsekedwa, ndipo mafuta sangathe kubwerera ku dera la mafuta, ndipo kupanikizika kumapitirira kuwonjezeka pamene plunger ikupitirizabe kutsika, kukhala pamwamba. -kukakamiza mafuta, kukakamiza valavu ya nozzle kutsegula ndikuyamba kupopera mbewu mankhwalawa.Kuthamanga kwambiri kwa jekeseni sikuli kumayambiriro kwa jekeseni, koma pafupi ndi mapeto a jekeseni.

Sitiroko yotsalira

Jekeseniyo imapitirira mpaka valavu ya solenoid itaya mphamvu, panthawi yomwe valavu ya singano ya solenoid imatsegulidwa, mafuta othamanga kwambiri amamasulidwa, amalowa m'dera la mafuta, ndipo valve ya jekeseni imatsekedwa.
