Kodi valavu yowongolera mafuta imagwira ntchito bwanji?
Valavu yowongolera kuthamanga kwa mafuta, yomwe imadziwikanso kuti valavu ya OCV, imagwiritsidwa ntchito kwambiri pa injini ya cvvt, ntchito yake ndikulamulira mafuta kulowa mu chipinda cha mafuta cha cvvt kapena kuchedwetsa chipinda cha mafuta posuntha valavu ya ocv kuti ipereke kuthamanga kwa mafuta kuti camshaft isunthe pa ngodya yokhazikika kuti iyambe. Ntchito ya valavu yowongolera mafuta ndikuwongolera ndikuletsa kupanikizika kwakukulu mu dongosolo lopaka mafuta la injini.
Valavu yowongolera mafuta imakhala ndi zigawo ziwiri zazikulu: kusonkhana kwa thupi ndi kusonkhana kwa actuator (kapena dongosolo la actuator), logawidwa m'magulu anayi: valavu yowongolera yokhala ndi mpando umodzi, valavu yowongolera yokhala ndi mipando iwiri, valavu yowongolera yokhala ndi mikono ndi valavu yowongolera yokhala ndi mzere wodziyimira payokha.
Kusiyanasiyana kwa mitundu inayi ya ma valve kungayambitse mapangidwe ambiri osiyanasiyana, iliyonse ili ndi ntchito zake, makhalidwe ake, ubwino ndi kuipa kwake. Ma valve ena owongolera ali ndi mikhalidwe yosiyanasiyana yogwirira ntchito kuposa ena, koma ma valve owongolera sali oyenera mikhalidwe yonse yogwirira ntchito kuti agwirizane kupanga yankho labwino kwambiri lowonjezera magwiridwe antchito ndikuchepetsa mtengo.
