一、VVT, eyaziwa nangokuthi isikhathi se-valve eguquguqukayo, ubuchwepheshe obusetshenziswa ezinjinini zepiston.
Njengamanje, izinjini eziningi ezikhiqizwa abakhiqizi sezamukele ubuchwepheshe be-VVT, eyaziwa nangokuthi injini ye-VVT.
Kusho ukuthi ngaphansi kwezimo ezithile, ngokulungisa kusengaphambili kanye nokubambezeleka kwe-engeli ye-valve yokungenisa, ukulungiswa kwevolumu yokukhipha kanye ne-exhaust volume kanye ne-valve overlap angle kuyenziwa, futhi umfutho wokuthatha nokusebenza kahle kuyakhuphuka ukuze uthole amandla enjini, i-torque nokunye. izici. ngcono.
Njengamanje, izinhlobo ezidumile yiMercedes-Benz, BMW, Toyota nokunye. Izici ezibalulekile ezihlobene nobuchwepheshe be-VVT yilezi: isivinini sokuphendula, ukunemba kokulungiswa kanye nokuzinza kokulungiswa.
Kuphela uma lezi zintathu zifaniswa nesakhiwo nokusebenza kwe-phaser kanye ne-valve yokulawula, kungatholakala isimo esingcono sokusebenza.

二, Indima ye-VVT
① amandla enjini
②uwonga uphethiloli
③ukukhishwa kwamapayipi exhaust
三、Kuzokwenzekani emotweni uma igiya le-VVT liphukile?
①umsindo ongajwayelekile
②Imoto izoba nokungenzi lutho okuzinzile, ukusheshisa okubi, njll.
③Ukusetshenziswa kukaphethiloli kuzokwenyuka kakhulu
④Izophinda idale umonakalo othile enjinini
Ngakho-ke, kuyadingeka ukwenza isondlo kusenesikhathi ukugwema izingozi.
