Intake manifold. (Chiwerengero cha intake).
Pa injini zojambulira mafuta za carburetor kapena throttle body, intake manifold imatanthauza intake payipi yochokera kumbuyo kwa carburetor kapena throttle body kupita patsogolo pa intake doko la cylinder head. Ntchito yake ndikugawa mpweya ndi mafuta ku intake doko lililonse la cylinder ndi carburetor kapena throttle body.
Pa injini yolowetsa mafuta kapena injini ya dizilo, intake manifold imangogawa mpweya woyera ku ma intake a silinda. Intake manifold iyenera kugawa mpweya, mafuta osakaniza kapena mpweya woyera mofanana momwe zingathere ku silinda iliyonse, kotero kuti kutalika kwa njira ya gasi mu intake manifold kuyenera kukhala kofanana momwe kungathekere. Pofuna kuchepetsa kukana kwa mpweya kuyenda ndikuwongolera mphamvu ya intake, khoma lamkati la intake manifold liyenera kukhala losalala.
Tisanalankhule za intake manifold, tiyeni tiganizire momwe mpweya umalowera mu injini. Mu mawu oyamba a injini, tatchula momwe pisitoni imagwirira ntchito mu silinda, injini ikalowa mu intake stroke, pisitoni imatsika kuti ipange vacuum mu silinda (ndiko kuti, kuthamanga kumakhala kochepa), kuti kusiyana kwa kuthamanga ndi mpweya wakunja kupangidwe, kuti mpweya ulowe mu silinda. Mwachitsanzo, aliyense ayenera kuti adabayidwa jakisoni ndikuwona momwe namwino adayamwira mankhwalawo mu chidebe cha singano! Ngati chidebe cha singano ndi injini, ndiye kuti pisitoni yomwe ili mu chidebe cha singano ikatulutsidwa, madziwo adzayamwidwa mu chidebe cha singano, ndipo umu ndi momwe injini imakokera mpweya mu silinda.
Chifukwa cha kutentha kochepa kwa gawo lolowera, zinthu zopangidwa ndi zinthu zosiyanasiyana zakhala chinthu chodziwika bwino cholowera, chomwe chili chopepuka komanso chosalala mkati, chingathandize kuchepetsa kukana ndikuwonjezera mphamvu ya gawo lolowera.
Chifukwa cha dzinalo
Intake manifold ili pakati pa valavu yopopera ndi valavu yopopera injini, chifukwa chake imatchedwa "manifold" ndikuti mpweya ukalowa mu valavu yopopera, pambuyo pa manifold buffer system, njira yoyendera mpweya "imagawidwa" pano, mogwirizana ndi kuchuluka kwa masilinda a injini, monga injini ya masilinda anayi ili ndi njira zinayi, ndipo injini ya masilinda asanu ili ndi njira zisanu, ndipo mpweya umalowetsedwa m'masilinda motsatana. Pa injini yachilengedwe yopopera, chifukwa intake manifold ili pambuyo pa valavu yopopera, pamene throttle ya injini yatsegulidwa, silinda singathe kuyamwa mpweya wokwanira, zomwe zimapangitsa kuti pakhale vacuum yambiri; Intake ya injini ikatsegulidwa, vacuum yomwe ili mu intake manifold idzakhala yochepa. Chifukwa chake, injini yoperekera mafuta yopangira jekeseni idzayika choyezera kuthamanga pa intake manifold kuti ipereke ECU kuti idziwe kuchuluka kwa injini ndikupereka kuchuluka koyenera kwa intake ya mafuta.
Ntchito zosiyanasiyana
Chotsukira mpweya cha Manifold sichimangogwiritsidwa ntchito popereka zizindikiro zokakamiza kuti zidziwike kuchuluka kwa injini, koma pali ntchito zambiri! Ngati brake ikufunikanso kugwiritsa ntchito chotsukira mpweya cha injini kuti chithandize, kotero injini ikayamba, pedal ya brake idzakhala yopepuka kwambiri, chifukwa cha chithandizo cha chotsukira mpweya. Palinso mitundu ina ya njira zowongolera liwiro zomwe zimagwiritsa ntchito chotsukira mpweya cha Manifold. Machubu a vacuum awa akatuluka kapena kusinthidwa molakwika, zimayambitsa mavuto owongolera injini ndikukhudza magwiridwe antchito a brake, kotero owerenga akulangizidwa kuti asasinthe molakwika machubu a vacuum kuti asunge chitetezo choyendetsa.
Kapangidwe kanzeru
Kapangidwe ka manifold olowa ndi chidziwitso chachikulu, kuti injini igwire ntchito mofanana, kutalika ndi kupindika kwa manifold a silinda iliyonse kuyenera kukhala kofanana momwe zingathere. Popeza injini imayendetsedwa ndi ma stroke anayi, silinda iliyonse ya injini idzapopedwa mu pulse mode, ndipo monga lamulo, manifold yayitali ndi yoyenera kugwira ntchito ya RPM yochepa, pomwe manifold yayifupi ndi yoyenera kugwira ntchito ya RPM yayikulu. Chifukwa chake, mitundu ina imagwiritsa ntchito manifples olowa kutalika kosiyanasiyana, kapena manifples olowa kutalika kosiyanasiyana, kuti injiniyo ikhale ndi magwiridwe antchito abwino m'madera onse othamanga.
kupambana
Ubwino waukulu wa pulasitiki yolowetsa mafuta ndi mtengo wake wotsika komanso kulemera kwake kopepuka. Kuphatikiza apo, popeza kutentha kwa PA kuli kotsika kuposa kwa aluminiyamu, nozzle yamafuta ndi kutentha kwa mpweya komwe kumabwera ndizochepa. Sikuti kungowonjezera mphamvu yoyambira kutentha, kuwonjezera mphamvu ndi mphamvu ya injini, komanso kupewa kutaya kutentha mu chubu mpaka pamlingo winawake ikayamba kuzizira, kufulumizitsa kukwera kwa kutentha kwa mpweya, ndipo khoma la pulasitiki yolowetsa mafuta ndi losalala, zomwe zingachepetse kukana kwa mpweya, motero kukonza magwiridwe antchito a injini.
Ponena za mtengo, mtengo wa zinthu za pulasitiki yolowetsamo zinthu ndi wofanana ndi wa aluminium intake manifold, ndipo pulasitiki yolowetsamo zinthu imapangidwa kamodzi, ndi chiwongola dzanja chachikulu; Kuchuluka kwa aluminium intake manifold blank casting ndi kochepa, mtengo wa makina ndi wokwera, kotero mtengo wopanga pulasitiki yolowetsamo zinthu ndi wotsika ndi 20%-35% kuposa wa aluminium intake manifold.
Zofunikira pa zinthu
1) Kukana kutentha kwambiri: pulasitiki yolowetsamo zinthu imalumikizidwa mwachindunji ndi mutu wa silinda ya injini, ndipo kutentha kwa mutu wa silinda ya injini kumatha kufika 130 ~ 150℃. Chifukwa chake, zinthu za pulasitiki zolowetsamo zinthu zimafunika kuti zipirire kutentha kwakukulu kwa 180 ° C.
2) Mphamvu yayikulu: pulasitiki imayikidwa pa injini, kuti ipirire kugwedezeka kwa injini yagalimoto, kugwedezeka kwa mphamvu ya throttle ndi sensor, kugwedezeka kwa intake pressure, ndi zina zotero, komanso kuonetsetsa kuti injiniyo siphulika ndi kuthamanga kwa ...
3) Kukhazikika kwa miyeso: Zofunikira pakulekerera miyeso ya kulumikizana pakati pa intake manifold ndi injini ndi zokhwima kwambiri, ndipo kuyika masensa ndi ma actuator pa manifold kuyeneranso kukhala kolondola kwambiri.
4) Kukhazikika kwa mankhwala: pulasitiki yolowetsa mafuta imakhudzana mwachindunji ndi mafuta ndi antifreeze coolant ikagwira ntchito, mafuta ndi solvent yamphamvu, ndipo glycol yomwe ili mu coolant imakhudzanso magwiridwe antchito a pulasitiki, chifukwa chake, kukhazikika kwa mankhwala a pulasitiki yolowetsa mafuta ndi kwakukulu kwambiri ndipo kuyenera kuyesedwa mosamala.
5) Kukhazikika kwa kutentha kwa thupi; Injini ya galimoto ikugwira ntchito kutentha kotentha kwambiri, kutentha kwa ntchito kumasintha mu 30 ~ 130 ° C, ndipo pulasitiki iyenera kutsimikizira kudalirika kwa nthawi yayitali kwa manifold.
