D-VVT injini ndiko kuenderera uye kusimudzira kweVVT, inogadzirisa matambudziko ehunyanzvi ayo VVT injini isingakwanise kukunda.

DYYT inomirira kuti Dual Variable Valve Timing . Inogona kunzi ndiyo fomu yepamusoro yezvino inoshanduka valve timing system tekinoroji.

Injini yeDVVT ndiyo inonyanya kukwikwidza hukuru hunoenderana nekukwidziridzwa kwakazara kweVVT injini tekinoroji. Yakashandiswa mumhando yepamusoro-soro seBMW 325DVVT. Kunyange zvazvo nheyo yeinjini yeDVVT yakafanana neyejini yeVVT, injini yeVVT inogona kungogadzirisa valve yekutora, asi injini yeDVVT inogona kugadzirisa mavharuvhu ekupinza uye kupera panguva imwe chete. Iyo Roewe 550 1.8LDVVT inokwanisawo kuwana imwe kona renji zvinoenderana nekumhanya kweinjini dzakasiyana. Chikamu chemukati chevharuvhu chinochinjika zvine mutsetse uye chine hunhu hwakanakisa hwekuchinjika kwakadzika, torque yakakwirira, marevolutions akakwira uye simba rakakura.

Injini yeD-VVT inoshandisa musimboti wakafanana kunjini yeVVT, uye inoshandisa iri nyore hydraulic cam system kuita mabasa ayo. Musiyano ndewekuti injini yeVVT inogona kungogadzirisa vharafu yekupinda, nepo injini yeD-VVT inogona kugadzirisa mavharuvhu ekutora uye kupera panguva imwe chete. Iyo ine yakanakisa hunhu hweyakaderera revolutions, yakakwirira torque, yakakwirira revolutions uye yakakwirira simba. chinzvimbo chinotungamira. Mukutaura kwevasina basa, kungofanana nekufema kwevanhu, kugona kudzora "exhale" uye "inhale" zvine rhythmically sezvinodiwa, hongu, kune kuita kwepamusoro pane kungodzora "inhale".
