Senza ntoni isivalo se-oyile?
I-valve yokulawula uxinzelelo lwe-oyile, eyaziwa ngokuba yi-valve ye-OCV, isetyenziselwa ikakhulu kwi-injini ye-cvvt, umsebenzi kukulawula ioli kwi-cvvt i-oyile yangaphambili okanye i-oyile yokulibaziseka ngokuhambisa i-ocv valve ukubonelela ngoxinzelelo lwe-oyile ukwenza i-camshaft ihambe kwi-Angle esisigxina ukuze iqalise. Umsebenzi wevalve yokulawula i-oyile kukulawula nokuthintela uxinzelelo olugqithisileyo kwinkqubo yokuthambisa i-injini.
Ivalve yokulawula i-oyile inamacandelo amabini aphambili: indibano yomzimba kunye nendibano ye-actuator (okanye inkqubo ye-actuator), yahlulwe yaba luthotho olune: ivalve yokulawula uthotho lwesihlalo esinye, ivalve yolawulo enezihlalo ezibini, ivalve yolawulo lwemikhono kunye nevalve yokulawula uthotho oluzimelayo.
Ukwahluka kweentlobo ezine zevalve kunokubangela inani elikhulu lezakhiwo ezisebenzayo ezahlukeneyo, nganye inezicelo zayo ezithile, iimpawu, iingenelo kunye nokungonakali. Ezinye iivalve zokulawula zinoluhlu olubanzi lweemeko zokusebenza kunezinye, kodwa iivalve zokulawula azifanelekanga kuzo zonke iimeko zokusebenza ngokubambisana ukwakha isisombululo esona sisombululo sokuphucula ukusebenza kunye nokunciphisa iindleko.
