Rashin aiki na firikwensin kewayawa "B" saurin shigar da injin turbine
Mene ne wannan yake nufi?
Wannan Lambar Matsalar Bincike (DTC) lambar watsawa ce gaba ɗaya, wanda ke nufin ya shafi duk abin hawa tun 1996 (Ford, Honda, Mazda, Mercedes, VW, da sauransu). Kodayake gabaɗaya a yanayi, takamaiman matakan gyara na iya bambanta dangane da alama / ƙirar.
Idan kun karɓi DTC P2768, mai yiwuwa ne saboda tsarin sarrafa wutar lantarki (PCM) ya gano siginar shigar da wutar lantarki mara tsayayye daga na'urar firikwensin saurin shigarwa (ko turbine) mai lakabin "B". Ko da yake shigarwar da na'urori masu saurin turbine da gaske iri ɗaya ne kuma suna aiki iri ɗaya, ƙayyadaddun ƙayyadaddun abubuwa sun bambanta daga masana'anta zuwa masana'anta.
A mafi yawan lokuta, firikwensin saurin shigarwa / turbine shine firikwensin lantarki na waya uku da aka yi amfani da shi don saka idanu kan saurin shigar da gearbox a cikin juyi a minti daya (rpm). Na'urar firikwensin galibi tana kusa da ƙarshen kararrawar (a kan hanyar shigar da watsawa) kuma an shigar da shi tare da ƙulle / ingarma ko kuma a ɗora kai tsaye cikin akwati na watsawa.
Babban (ko shigarwar) ramin watsawa an haɗe shi har abada zuwa ko dai injin dabaran motsi ko tsararrun tsararrun tsarukan. Lokacin da injin da ke gudana yana watsa RPM zuwa watsawa, maɓallin shigarwar (ko dabaran jet) yana gudana kusa da ƙarshen firikwensin. Ƙarfe na ƙarfe (ko dabaran reactor) yana kammala aikin lantarki / lantarki tare da firikwensin. An ƙirƙiri ƙirar lantarki lokacin da aka katse kewaye ta hanyar tsagi (ko notched) sassan da ke wucewa da firikwensin. PCM ta gane da'irar a matsayin tsarin igiyar ruwa, wanda aka tsara ta don fassara azaman shigarwar wutar lantarki / saurin turbine.
