Mu dongosolo la mabuleki a pneuamtic, mpweya wopanikizika ndi njira yogwirira ntchito yomwe imagwiritsidwa ntchito kusunga kuthamanga kokhazikika ndikuwonetsetsa kuti mpweya ndi woyera mokwanira kuti valavu igwire ntchito bwino. Zinthu ziwiri za chowumitsira cha molecular sieve ndi chowongolera kuthamanga kwa mpweya zimapangidwa kuti zipereke mpweya woyera komanso wouma wopanikizika wa dongosolo la mabuleki ndikusunga kuthamanga kwa dongosolo kukhala koyenera (nthawi zambiri pa 8 ~ 10bar).
Mu dongosolo la mabuleki a galimoto, mpweya wopopera mpweya umatulutsa mpweya wokhala ndi zinthu zodetsa monga nthunzi ya madzi, ngati sunakonzedwe, zomwe zingasandulike madzi amadzimadzi ndikuphatikizidwa ndi zinthu zina zodetsa kuti zipangitse dzimbiri, ngakhale kuzizira kwa trachea kutentha kwambiri, zomwe zimapangitsa kuti valavu itaye mphamvu.
Choumitsira mpweya wa galimoto chimagwiritsidwa ntchito kuchotsa madzi, madontho a mafuta ndi zinthu zina zodetsa mpweya wopanikizika, chimayikidwa pambuyo pa compressor ya mpweya, chisanayikidwe valavu yoteteza ya ma loops anayi. Ndipo chimagwiritsidwa ntchito kuziziritsa, kusefa ndi kuumitsa mpweya wopanikizika, komanso chimatha kuchotsa nthunzi ya madzi, mafuta, fumbi ndi zinthu zina zodetsa, zomwe zimapangitsa kuti mpweya wouma komanso woyera ukhale wabwino kwambiri.
Chowumitsira mpweya cha galimoto ndi chowumitsira chobwezeretsa mphamvu chokhala ndi sieve ya molekyulu ngati desiccant yake. Sieve ya molekyulu ya JZ-404B ndi chinthu chopangidwa ndi desiccant chomwe chimakhala ndi mphamvu yamphamvu yothira madzi m'mamolekyu amadzi. Gawo lake lalikulu ndi kapangidwe ka microporous ka alkali metal aluminiyamu silicate compound yokhala ndi mabowo ndi mabowo ambiri ofanana komanso oyera. Mamolekyu amadzi kapena mamolekyu ena amamatiridwa mkati mwa dzenjelo, ndi ntchito yotsekereza mamolekyu. Sieve ya molekyulu ili ndi chiŵerengero chachikulu cha kulemera kwa adsorption ndipo imasungabe mamolekyu amadzi bwino kutentha kwa 230 ℃.
Chinyezi chomwe chili mu dongosolochi chidzawononga payipi ndikukhudza momwe braking imagwirira ntchito, ndipo chingayambitsenso kulephera kwa braking system. Chifukwa chake, chisamaliro chiyenera kuperekedwa pa kutulutsa madzi pafupipafupi mu dongosololi ndikusintha nthawi zonse chowumitsira cha molecular sieve.
