Kodi kulamulira kwa turbocharger ya magalimoto ndi chiyani?
Njira yowongolera ya turbocharger yamagalimoto imadziwika makamaka ndi makina owongolera kuthamanga kwa mpweya wa turbocharger woyendetsedwa ndi magetsi. Dongosololi limapangidwa ndi valavu yochepetsera kuthamanga kwa mpweya, actuator ya pneumatic, valavu ya bypass ndi supercharger. Kuwongolera kuthamanga kwa mpweya wa system kumachitika kudzera mu kutsegula ndi kutseka kwa bypass valve: pamene bypass valve yatsekedwa, pafupifupi mpweya wonse wa utsi umadutsa mu booster, ndipo kuthamanga kwa booster kumawonjezeka; Pamene bypass valve yatsegulidwa, gawo la mpweya wa utsi limatulutsidwa mwachindunji kudzera mu bypass channel, ndipo kuthamanga kwa booster kumachepa .
Kutsegula ndi kutseka kwa valavu yodutsa mpweya kumachitika ndi ECU (Electronic control Unit) kudzera mu ulamuliro wa valavu yochepetsera kupanikizika ndi actuator ya pneumatic . ECU imalamulira kukakamiza mphamvu malinga ndi kupanikizika kwa manifold, ndipo valavu yodutsa mpweya imatsegulidwa mwachangu komanso molimbika kuti ipewe kudzaza kwambiri kwa makina ndi kutentha kwa injini pa liwiro lalikulu. Kuphatikiza apo, mitundu ina imagwiritsanso ntchito njira yowongolera yotsekedwa, kudzera mu sensa ya malo kuti ipereke zotsatira zenizeni ku ECU, kusintha malinga ndi kupotoka, kuti iwongolere molondola mphamvu ya injini .
Mfundo yogwira ntchito ya turbocharger ndi kuyendetsa turbine kudzera mu mpweya wotulutsa utsi wochokera ku injini, kenako kukanikiza mpweya wolowera kuti uwonjezere kuchuluka kwa mpweya, motero kumawonjezera mphamvu yoyaka ndi kutulutsa mphamvu . Turbocharger imagwiritsa ntchito mphamvu ya inertia ya mpweya wotulutsa utsi wochokera ku injini kukankhira turbine mu chipinda cha turbine, imayendetsa coaxial impeller kuti ikanikize mpweya mu silinda, imawonjezera kuthamanga ndi kuchuluka kwa mpweya, motero imawonjezera mphamvu yotulutsa ya injini .
Ntchito zazikulu za ma turbocharger a magalimoto zimaphatikizapo zinthu izi:
Wonjezerani mphamvu ya injini ndi mphamvu yake: Ma turbocharger amawonjezera kuchuluka kwa mpweya wolowa mu silinda, zomwe zimathandiza injini kuti ilowe mafuta ambiri panthawi yomweyo, motero imawonjezera mphamvu ya injini ndi mphamvu yake. Kawirikawiri, ma turbocharger amatha kuwonjezera mphamvu ya injini ndi 20% mpaka 40%, ndipo mphamvu yake ndi 30% mpaka 50%.
Chepetsani kugwiritsa ntchito mafuta ndi mpweya woipa: Ma Turbocharger amachepetsa kugwiritsa ntchito mafuta ndi mpweya woipa mwa kukonza bwino kuyaka kwa injini ndikuwonjezera mphamvu ya kutentha. Makamaka, turbocharger imatha kuchepetsa kugwiritsa ntchito mafuta kwa injini ndi 5% mpaka 10%, ndipo kutulutsa mpweya woipa monga CO, HC ndi NOx kumachepetsedwanso mofanana.
Kusunga bwino mafuta: Mainjini okhala ndi ma turbocharger amayaka bwino, zomwe zimasunga 3% mpaka 5% ya mafuta. Kuphatikiza apo, ma turbocharger amakonza mawonekedwe ofanana ndi injini komanso mawonekedwe oyankha kwakanthawi kuti mafuta azisungidwa bwino.
Kuonjezera kusinthasintha ndi kudalirika kwa injini: Turbocharger imatha kupanga injini pamalo osiyanasiyana okwera, kutentha ndi mikhalidwe yonyamula katundu kuti isunge magwiridwe antchito abwino komanso kukhazikika, kupewa mphamvu zochepa za injini, kugundana, kutentha kwambiri ndi mavuto ena. Nthawi yomweyo, ma turbocharger amathanso kukulitsa moyo wa injini ndikuchepetsa kulephera kwake.
Ntchito yolipirira phiri la plateau : m'dera la plateau, chifukwa cha mpweya wochepa, magwiridwe antchito a injini wamba adzakhudzidwa ndipo mphamvu idzachepa. Turbocharger imatha kulipira bwino kutayika kwa mphamvu komwe kumachitika chifukwa cha mpweya wochepa mwa kuwonjezera kuchuluka kwa intake.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina pandi tsamba!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd.yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zomwe zalandiridwakugula.
