Solenoid valve SCV control valve 294200-0660 mafuta metering valve

Mfundo yogwirira ntchito ya valve yoyezera mafuta

1. Pamene coil yolamulira ilibe mphamvu, valavu ya metering proportional valve imakhalapo, yomwe timayitcha kuti valve solenoid yotseguka, yomwe ingapereke mafuta ochuluka kwambiri ku mpope wa mafuta. ECU imachulukitsa kapena kuchepetsa kuchuluka kwa mafuta posintha gawo la pampu yamafuta apamwamba kwambiri ndi chizindikiro cha pulse.

2, apa titha kumvetsetsa gawo la metering yamafuta ngati chosinthira chamagetsi, chomwe chimayang'anira kuzungulira kwamafuta komwe kumapita ku mpope wamafuta. Pamene chosinthira sichimayatsidwa, kuchuluka kwa mafuta omwe amaperekedwa ku pampu yamafuta ndikokulirapo, m'malo mwake, pomwe valavu ya solenoid ili pamalo operekera mafuta a zero, kuperekedwa kwa pampu yamafuta kumatsogozedwa.Kuchuluka kwa mafuta kuyenera kukhala zero.

3. Mafuta a metering unit ndi gawo lolondola. Ngati kukonza sikuli koyenera kapena kugwiritsa ntchito zinthu zosefera zabwino, nthawi zambiri kumabweretsa madzi ochulukirapo kapena zonyansa mumafuta, zomwe zimapangitsa kuti valavu yamagetsi yamafuta ivale kapena kumamatira, zomwe zimapangitsa kuti injini isagwire bwino ntchito.

Ngati gawo la metering la mafuta litawonongeka, jekeseni wa jekeseni wa mafuta adzadulidwa, ndipo valavu ya metering metering solenoid ya mafuta imatsekedwa kwathunthu, zomwe zingalepheretse kuthamanga kwa njanji ya mafuta kuti isapitirire kukwera.

Mafuta a metering unit ndi gawo lolondola kwambiri, ndipo ngati nthawi zambiri mumagwiritsa ntchito fyuluta yamafuta abwino, imatha kuwononga gawo la metering yamafuta. Mafuta fyuluta akhoza zosefera chinyezi ndi zosafunika mu mafuta, ngati ntchito otsika mafuta fyuluta, zidzachititsa kuchuluka chinyezi kapena zosafunika mu mafuta, zomwe zidzachititsa kuwonongeka kwa mafuta metering wagawo.

Chigawo cha metering chamafuta chimayikidwa pamalo olowera pampu yamafuta othamanga kwambiri. Gawoli limatha kusintha momwe mafuta amaperekera komanso kuthamanga. Gawo ili limayendetsedwa ndi ecu. Ngati mafuta metering unit awonongeka, kuwala kolakwika kudzayatsa pa bolodi ndipo ecu idzadula jekeseni wamafuta ku injini. Ngati kulephera uku kukuchitika mukuyendetsa, galimoto yokoka imafunika panthawiyi.
