Ntchito ya valve yowongolera mafuta.
Ntchito yayikulu ya valavu yowongolera mafuta ndikuchepetsa kupanikizika kwakukulu kwa makina opaka mafuta kuteteza kupanikizika kwakukulu kuti zisawononge zigawo za mafuta odzola ndikupewa kuchitika kwa mafuta. Valve yowongolera mafuta imawonetsetsa kuti makina opangira mafuta azigwira bwino ntchito posintha kukakamiza kwamafuta. Nthawi zambiri imayikidwa pa njira yamafuta yotulutsira pampu yamafuta kuti iwunikire bwino ndikuwongolera kuthamanga kwamafuta. Ngati valavu yoyendetsera mafuta ikulephera, ikhoza kuchititsa kuti galimotoyo iwonongeke panthawi yoyendetsa galimoto, ndipo mphamvu ya mafuta idzakwera mosadziwika bwino, zomwe zidzakhudza momwe galimotoyo ikuyendera.
Mfundo yogwira ntchito ya valve yolamulira mafuta imaphatikizapo gulu la ma valve ndi gulu la actuator, lomwe limagwirira ntchito limodzi kuti likwaniritse lamulo la kuthamanga kwa mafuta. Mu dongosolo la nthawi ya valve, valavu yoyendetsera mafuta imasankha maulendo osiyanasiyana amafuta kuti alankhule ndi wolamulira wa VVT molingana ndi malangizo a injini ECU, kotero kuti pasadakhale, kutsalira kapena kusunga zigawo zitatu zosiyana zogwirira ntchito. Makina owongolera awa amawonetsetsa kuti valavu imatsegula ndikutseka nthawi yabwino, potero imakulitsa magwiridwe antchito a injini.
Kuphatikiza apo, mafuta, mafuta a injini, amagwira ntchito yofunikira pakuwongolera injini ndikuchepetsa kuvala, kuziziritsa kothandizira ndi kuziziritsa , kutsekereza kutayikira , kupewa dzimbiri ndi kupewa dzimbiri , kugwedezeka kwamphamvu ndi zina zotero. Amadziwika kuti "magazi" agalimoto. Ntchito ya valavu yowongolera mafuta ndikuwongolera ndikuletsa kukakamiza kwa makina opangira mafuta kuti asakwere kwambiri kuti ateteze injini kuti isawonongeke.
Vavu yowongolera mafuta yathyoka
Kuchita kwa kulephera kwa valve yowongolera mafuta kumaphatikizapo:
Galimotoyo imatha kuyimilira mwadzidzidzi pakuyendetsa, zomwe zimachitika chifukwa cha valavu yowongolera mafuta silingasinthe kupanikizika kwamafuta nthawi zonse, zomwe zimapangitsa kuti injini ikhale yosakwanira.
Kuthamanga kwamafuta ndikokwera modabwitsa, ngati kuthamanga kwamafuta kuli kokwera kwambiri, kumayambitsa kusakaniza kochuluka kwambiri, utsi wakuda wapaipi yotulutsa, komanso mphamvu yagalimoto yosakwanira. Kuphatikiza apo, kuthamanga kwamafuta kwambiri kumatha kupangitsanso kuti mafuta azikhala otsika kwambiri kapena osatheka kukhazikitsa, potero amawonjezera kugwiritsa ntchito mafuta.
Mafuta adzayaka, zomwe zimapangitsa kuti mafuta azigwiritsidwa ntchito kwambiri, kutulutsa mpweya wambiri, kuthamanga kosasunthika kosagwira ntchito, kukulitsa zoopsa zobisika zagalimoto ndikuwonjezera mavuto azachuma. Kuwotcha mafuta kumapangitsanso kuchuluka kwa kaboni m'chipinda choyatsira injini, kuthamanga kofooka, kuthamanga pang'onopang'ono, mphamvu zosakwanira ndi zotsatira zina zoyipa.
Kuwonongeka kwa ma valve owongolera mafuta kunayambitsa kugwedezeka kwa injini, kuyatsa kwamagetsi. Khodi yolakwika yotuluka ikhoza kukhala yotseguka ya VVT control solenoid valve, yozungulira pang'ono mpaka pansi, kapena gawo lalifupi kupita ku electrode yabwino. Munthawi yanthawi zonse, mawonekedwe amagetsi otulutsa a terminal ayenera kukhala chizindikiro chokulirapo kuposa chizindikiro chabwino, ndipo ngati mawonekedwewo akulakwika, amayambitsa kulephera kwa injini.
Choncho, pamene kuwonongeka kwa valve yoyendetsera mafuta kumapezeka, kuyenera kuchitidwa mwamsanga kuti apewe zotsatira zoopsa kwambiri.
Kodi valavu yowongolera mafuta imasweka bwanji pagalimoto?
Valve yosweka yamafuta imatha kubweretsa zotsatira zoyipa zingapo, kuphatikiza kuwotcha mafuta, kuchuluka kwamafuta, kutulutsa mpweya wambiri, kuthamanga kosasunthika kosagwira ntchito, komanso mphamvu zosakwanira.
Kuwotcha mafuta: Kulephera kwa ma valve owongolera mafuta kumayambitsa kuyaka kwamafuta, zomwe zimapangitsa kuti injini ikhale yosakwanira, kukulitsa injini kutayika, ngakhale kulephera.
Kuchuluka kwa mafuta: Kuwotcha mafuta kumapangitsa kuti injini iwononge mafuta ambiri, zomwe zidzawonjezera kugwiritsa ntchito mafuta m'galimoto.
Kutulutsa mpweya wambiri: kuwotcha mafuta kumapangitsa kuti pakhale mpweya wambiri, zomwe zimapangitsa kuti chilengedwe chiwonongeke.
Kusakhazikika kwa Idling: Kulephera kwa valve yowongolera mafuta kumayambitsa kusakhazikika kwa injini, galimoto imagwedezeka ndi zochitika zina poyendetsa.
Mphamvu zosakwanira: Kulephera kwa valve yoyendetsa mafuta kudzatsogolera ku mphamvu ya injini yosakwanira, ndipo padzakhala mavuto monga kuthamanga kofooka pamene galimoto ikuyendetsa galimoto.
Galimoto ikhoza kuyimitsa: Ngati valavu yowongolera mafuta yathyoka, galimotoyo imatha kuyimilira ndikuyendetsa.
Kuwonjezeka kwa injini kuyaka chipinda kaboni: Kuwotcha mafuta kumabweretsa kuchulukira kwa injini kuyaka chipinda kaboni, mathamangitsidwe ofooka, liwiro pang'onopang'ono.
Kuwonjezeka kwachuma chachuma: Kuwotcha mafuta kudzawonjezera katundu wachuma wa galimoto, chifukwa ndalama zambiri zamafuta ndi kukonza ndizofunikira.
Zimakhudza magwiridwe antchito a injini: valavu yowongolera mafuta yasweka, zomwe zimapangitsa kuti kupanikizika kwa makina opangira mafuta a injini kukhala okwera kwambiri, zomwe zimakhudza magwiridwe antchito a injini.
Ntchito yayikulu ya valavu yowongolera mafuta ndikuwongolera ndikuletsa kupanikizika kwa makina opaka mafuta a injini kukhala okwera kwambiri. Choncho, pamene valavu yoyendetsera mafuta ikulephera, iyenera kuthandizidwa panthawi yake kuti injini isawonongeke.
Chonde tiyimbireni ngati mukufuna such mankhwala.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zolandiridwa kuti mugule.
