Yintoni eyenziwa yivalvu yokulawula ioyile?
Ivalvu yokulawula uxinzelelo lweoyile, ekwaziwa ngokuba yivalvu ye-OCV, isetyenziswa kakhulu kwinjini ye-cvvt, umsebenzi wayo kukulawula ioyile ingene kwigumbi leoyile eliphambili le-cvvt okanye ukulibazisa igumbi leoyile ngokushukumisa ivalvu ye-ocv ukuze inike uxinzelelo lweoyile ukwenza i-camshaft ihambe kwi-engile emiselweyo ukuze iqale. Umsebenzi wevalvu yokulawula ioyile kukulawula nokuthintela uxinzelelo olugqithisileyo kwinkqubo yokuthambisa injini.
Ivalvu yokulawula ioyile inamacandelo amabini aphambili: indibano yomzimba kunye nendibano ye-actuator (okanye inkqubo ye-actuator), yahlulwe yaba ziichungechunge ezine: ivalvu yokulawula uthotho lwesihlalo esinye, ivalvu yokulawula uthotho lwezihlalo ezimbini, ivalvu yokulawula uthotho lwemikhono kunye nevalvu yokulawula uthotho oluzimeleyo.
Ukwahluka kweentlobo ezine zeevalvu kunokubangela inani elikhulu lezakhiwo ezahlukeneyo ezisebenzayo, nganye inezicelo zayo, iimpawu zayo, iingenelo kunye neengxaki zayo. Ezinye iivalvu zokulawula zineemeko zokusebenza ezahlukeneyo kunezinye, kodwa iivalvu zokulawula azifanelekanga kuzo zonke iimeko zokusebenza ukuze zakhane isisombululo esingcono sokuphucula ukusebenza kunye nokunciphisa iindleko.
