Chotenthetsera Mphamvu Chosinthasintha
1, kasupe kakang'ono ka mafuta opanikizika kwambiri kamene kamakhala ndi liwiro lodzaza mafuta mwachangu, kakhoza kusankha kasupe kakang'ono kodzaza mafuta, kasupe wouma pang'ono (nthawi zambiri amapanga kasupe wouma, muyenera kuganizira za kuthamanga kwa mafuta kotsika kwambiri, malire ovalidwa ndi unyolo, kasupe wouma wamba, kuti mugwiritse ntchito mphamvu yothandiza mwachangu, nthawi zambiri mumasankha m'mimba mwake waukulu wa plunger. Izi zimapangitsa kuti injini iyambe, kasupe wouma ndi wovuta kupanga mwachangu kuti apange mphamvu yochepetsera madzi, kufunikira kwa mphamvu yayikulu ya masika kuti ayambe kumangitsa, kasupe kakang'ono kangachepetse kupsinjika ndi kuuma kwa kufunika kwa kasupe wouma. Mphamvu yodzaza mafuta ouma wamba ndi 30-40N, mphamvu yodzaza mafuta ouma a VFT ndi 2 ~ 4N, ndipo mphamvu yodzaza mafuta ouma akuluakulu ndi 7 ~ 10N, ndipo kusinthako n'kodziwikiratu.
2, chothandizira chachikulu cha plunger ndi chokhazikika, mphamvu yamphamvu yoyamwa kugwedezeka, imatha kuthana ndi liwiro lalikulu komanso zinthu zazikulu zolimbikitsira;
3. Valavu yoyezera yokhala ndi mutu waukulu wa plunger imatha kuchepetsa mphamvu yayikulu ya plunger ndikuchepetsa mphamvu ya unyolo.
Mwachidule, VFT ndi kuphatikiza kwa njira yowongolera ya PAWS ya nsomba ndi chimbalangondo, kumbali imodzi kuti igwiritse ntchito mwayi woyankha mwachangu kwa plunger yaying'ono, kumbali ina, dongosololi lili ndi kukhazikika kwa kugwiritsa ntchito ma plunger akuluakulu. Mwanjira ina, VFT imazindikira kugawa kwa ntchito pakati pa ma plunger awiriwa, ndipo kulamulira kwa mphamvu ya masika kumayikidwa kokha pa kapangidwe ka plunger yaying'ono + kasupe, ndichifukwa chake mainjiniya a BorgWarner akufotokoza kuti mtundu uwu wa Tensioner umatchedwa Variable Force Tensioner: Zipinda ziwiri zosiyana zodziyimira pawokha kuti ziwongolere mphamvu yosinthasintha ya masika ndi mphamvu yamadzimadzi.
Malinga ndi mfundo yogwirira ntchito, sikovuta kudziwa mawonekedwe a curve yodziwika bwino ya VFT. Kutsitsa mphamvu yamadzimadzi mu gawo lokonzanso, mphamvu yochepa yobwezera mphamvu ya masika yoyambira kudzaza imakhala pafupi ndi mzere wa zero; Pa gawo loyambirira la kukakamiza, plunger yaying'ono imayankha mwachangu ndipo mphamvu yobwezera imakwera mwachangu. Panthawi yokakamiza, ma plunger awiriwa amatulutsa mafuta nthawi imodzi, kuthamanga kwamadzimadzi kumayikidwa pamwamba, ndipo malo otsetsereka ndi otsetsereka. Mphamvu yayikulu yobwezera mphamvu imayendetsedwa ndi valavu yochepetsera kukakamiza kuti zitsimikizire kuti mphamvu ya unyolo wa dongosolo la nthawi ili mkati mwa mulingo wotetezeka wa malire otopa. Ndi kuyankha mwachangu, VFT imatha kupeza malo akulu opindika pansi pa mphamvu yaying'ono yobwezera, ndipo makhalidwe ochepetsa mphamvu ali pafupi ndi mkhalidwe woyenera.
