Yini eyenziwa yivalvu yokulawula uwoyela?
Ivalvu yokulawula umfutho kawoyela, eyaziwa nangokuthi ivalvu ye-OCV, isetshenziswa kakhulu enjinini ye-cvvt, umsebenzi wayo ukulawula uwoyela ungene ekamelweni likawoyela le-cvvt noma ukubambezela igumbi likawoyela ngokuhambisa ivalvu ye-ocv ukuze inikeze umfutho kawoyela ukuze i-camshaft ihambe nge-engela eqinile ukuze iqale. Umsebenzi wevalvu yokulawula uwoyela ukulawula nokuvimbela umfutho owedlulele ohlelweni lokugcoba injini.
Ivalvu yokulawula uwoyela inezingxenye ezimbili eziyinhloko: ukuhlanganiswa komzimba kanye nokuhlanganiswa kwe-actuator (noma uhlelo lwe-actuator), oluhlukaniswe ngochungechunge olune: ivalvu yokulawula uchungechunge lwesihlalo esisodwa, ivalvu yokulawula uchungechunge lwezihlalo ezimbili, ivalvu yokulawula uchungechunge lwemikhono kanye nevalvu yokulawula uchungechunge oluzimele.
Ukwehlukahluka kwezinhlobo ezine zamavalvu kungabangela inani elikhulu lezakhiwo ezahlukene ezisebenzayo, ngayinye inezinhlelo zayo zokusebenza ezithile, izici, izinzuzo kanye nokungalungi. Amanye amavalvu okulawula anezimo zokusebenza eziningi kunezinye, kodwa amavalvu okulawula awafaneleki kuzo zonke izimo zokusebenza ukuze akhe ndawonye ikhambi elihle kakhulu lokuthuthukisa ukusebenza nokunciphisa izindleko.
