Kapangidwe ndi Mfundo ya injector
Injector yamafuta ndi chipangizo cholondola chomwe chili ndi makina olondola kwambiri, omwe amafunikira kusuntha kwakukulu kosunthika, mphamvu zotsutsana ndi kutsekeka komanso kuwononga kuwononga, komanso ntchito yabwino ya atomization. Mfundo yogwirira ntchito ya jekeseni wamafuta ndikulandira chizindikiro cha jekeseni wamafuta chomwe chimatumizidwa ndi ECU kuti chiwongolere kuchuluka kwa jakisoni wamafuta.
Injector, yomwe ndi valve solenoid, imayang'aniridwa ndi injini yoyang'anira injini. Mafuta pansi pa kupanikizika kwa chitoliro chogawa mafuta amalowa mu jekeseni wa mafuta, pansi pa mphamvu ya masika obwerera, valve ya singano ili mu malo otsekedwa, ndipo jekeseni wa mafuta sangathe kulowetsa mafuta; pamene ECU imayang'anira koyilo ya solenoid ya jekeseni yamafuta kuti ikhale yopatsa mphamvu, mphamvu ya maginito yopangidwa ndi koyilo ya solenoid imayendetsa zida, Vavu ya singano imasunthira mmwamba, valavu ya singano imatsegulidwa, ndipo jekeseni wamafuta amabaya mafuta. Nthawi zambiri, kukweza kwa valavu ya singano ya jekeseni kumakhala pafupifupi 0.1mm.
Mfundo ya dera loyang'anira jekeseni wa mafuta ikuwonetsedwa mu Chithunzi 1. Chojambula chamagetsi cha jekeseni wamafuta chimatsogolera ku mawaya awiri, waya umodzi ndi magetsi, omwe amapereka magetsi a 12V pambuyo poti kiyi yoyatsira itsegulidwa, ndipo waya winayo. dera lapansi lomwe limayendetsedwa ndi unit control unit. Pamene jekeseni wa mafuta akufunika kutsegula jekeseni wa mafuta, magetsi oyendetsa magetsi a ECU amayendetsa pansi pa mzerewu kudzera mu triode, ndipo mphamvu yamagetsi imayenda kudzera muzitsulo zamagetsi, ndipo jekeseni ya mafuta imatsegula jekeseni wa mafuta. Nthawi iliyonse ECU imayang'anira kuthamanga kwa maginito kwa waya wa jekeseni wamagetsi amatchedwa mafuta a jakisoni amtundu wa pulse, womwe uli mumitundu ya 2 ~ 10ms.
