Evolution of Intake Manifolds
Zisanafike 1990, magalimoto ambiri anali ndi injini za carburetor.M'magalimoto awa, mafuta amamwazikana mkati mwa ma intake manifold kuchokera ku carburetor.Chifukwa chake, kuchuluka kwamafuta ndikoyenera kubweretsa kusakaniza kwamafuta ndi mpweya ku silinda iliyonse.
Pofuna kuteteza mafuta kuti asapangike pamakoma ozizira azomwe amadya, kutentha kumafunika.Izi zitha kubwera kuchokera ku kutentha kwamagetsi muzosakanizika, mpweya wotuluka pansi, kapena kuchokera ku zoziziritsa kuzizira zomwe zimazungulira mozungulira.Zambiri zomwe zimadya kuyambira nthawi ino zimapangidwa ndi chitsulo chosungunuka kapena aluminiyamu.
Kumayambiriro kwa zaka za m'ma 90, injini zambiri zinayamba kugwiritsa ntchito jakisoni wamafuta kuti apereke gasi ku masilindala.M'mainjini awa, kuchuluka kwa kudya kumangokhudza kugawa mpweya.Popeza kutentha sikufunikanso kuti tipewe kusungunuka kwamafuta, zida zina zitha kugwiritsidwa ntchito.Ndizofala kuwona ma aluminiyamu otayidwa komanso ma pulasitiki ochulukirapo pamagalimoto amakono.
Ntchito?
Manifold intake, yomwe imadziwikanso kuti inlet manifold, imagawa mpweya ku masilindala a injini, ndipo pamagalimoto ambiri imakhalanso ndi majekeseni amafuta.Pamagalimoto akale opanda jekeseni wamafuta kapena jekeseni wa throttle body, manifold ambiri amatenga mafuta osakanikirana ndi mpweya kuchokera ku carburetor/throttle body, kupita ku mitu ya silinda.
Zobwezeredwa zimalowetsa mpweya m'chipinda choyaka pamoto, ndipo mpweya uwu umasakanizidwa ndi mafuta kuchokera ku jekeseni, kenako kuyaka kumapitirira.
Mpweya umafika mosiyanasiyana kudzera pagulu lotsukira mpweya, lomwe lili ndi fyuluta yagalimoto yagalimoto.
Zosefera za mpweya zimayimitsa fumbi ndi matupi ena akunja kuti asalowe ndikuwononga injini, ndiye ndikofunikira kuti muzisintha pafupipafupi.
Plenum ndi chibowo chachikulu chomwe chili pamwamba pa manifold.Imakhala ngati nkhokwe, ikugwira mpweya mpaka itakonzeka kulowa mu masilinda.Plenum imagawa mofanana mpweya kwa othamanga isanadutse valavu yolowera.
Kukula kwa plenum kumakhudza ntchito ya injini.Aftermarket manifolds amatha kukhala ndi gawo logawanika lomwe limatha kugawidwa pawiri.Kapangidwe kameneka kamapangitsa kukhala kosavuta kuyeretsa mkati mwazochuluka.
Othamanga ndi machubu omwe amanyamula mpweya kuchokera ku plenum kupita ku doko lolowera pamutu uliwonse wa silinda.Kwa injini zojambulidwa ndi mafuta, pali madoko a ma injectors amafuta pa wothamanga aliyense.Mafuta amabayidwa mpweya usanalowe padoko.
Kukula kwa othamanga ndichinthu chofunikira kwambiri pankhani ya magwiridwe antchito a injini.M'lifupi ndi kutalika kwa othamanga zimatsimikizira kumene mphamvu ya akavalo ya injini ili.
Ma Manifolds Ogwira Ntchito
Mapangidwe a kuchuluka kwa madyedwe amakhudza kuchuluka kwa mpweya womwe umaperekedwa komanso mwachangu bwanji.Chilichonse kuyambira m'mimba mwake mpaka kukula ndi mawonekedwe a plenum ndi othamanga amatha kusintha momwe mpweya umaperekedwa komanso nthawi.
Magwiridwe ambiri amakhala ndi ma plenum akuluakulu komanso othamanga kuti aziyenda bwino.Manifolds okhala ndi plenum yogawanika amalola kupukuta ndi kuyeretsa kosavuta.Spacers nthawi zina imatha kuwonjezeredwa kuti musinthe kukula kwa plenum, zomwe zingakuthandizeni kupeza ma curve ena a injini.
Plenum yomwe imapendekera ku silinda yomaliza idzaonetsetsa kuti mpweya ugawidwe.Ma manifolds ena amakhalanso ndi mpweya womwe umathandizira kuchepetsa kuchuluka kwa kutentha kwa mphamvu zambiri.Kuchuluka kwa magwiridwe antchito kumagwirizana bwino ndi utsi watsopano, mpweya wozizira, mitu ya silinda, ndi matupi opumira.
Chabwino, tsopano tikuwona zomwe zizindikiro za kudya koyipa ndi ziti?
Yankho ndilakuti: Pamene mukuchita, pangakhale phokoso, kuyimba mluzu, kuyamwa, kumeza kapena ngakhale phokoso.Galimotoyo imathanso kukhala yaukali pamene ikuchita idling ndipo injini imatha kuyimilira pang'onopang'ono.Kapena, mukazimitsa kuyatsa kwa galimotoyo, ikhoza kuthamanga kwa nthawi yaitali kuposa momwe iyenera kukhalira.Itha kumvanso ulesi pothamanga.
Ngati muli ndi vuto monga pamwambapa, pitani ku garaja ndikuyang'ana, mwina mukufunika kusintha njira zingapo zatsopano.
