Kodi choziziritsira galimoto n'chiyani?
Choziziritsira m'galimoto ndi chipangizo chothandizira kutenthetsa kutentha kwa injini zokhala ndi turbocharger, chomwe chimagwiritsidwa ntchito kuziziritsa mpweya wotentha kwambiri pambuyo pa turbocharger kuti injini izigwira ntchito bwino komanso kuti mphamvu zake zizigwira ntchito bwino.
Tanthauzo loyambira ndi ntchito
Intercooler, gawo lofunika kwambiri la injini yodzaza mphamvu monga injini ya turbocharged kapena supercharged, imayikidwa pakati pa supercharger ndi intake manifold. Ntchito yake yayikulu ndikuchepetsa kutentha kwa mpweya wodzaza mphamvu. Ntchito zake zazikulu ndi izi:
Youdaoplaceholder0 Kuziziritsa mpweya wotentha : Panthawi yodzaza kwambiri, mpweya umapanikizika, zomwe zimapangitsa kuti kutentha kwake kukwere (mpaka 200 ° C). Choziziritsiracho chimachepetsa kutentha kufika pamlingo woyenera (nthawi zambiri 50-60 ° C) kudzera mu kufalitsa kutentha, zomwe zimaletsa kutentha kwambiri pa injini.
Youdaoplaceholder0 Kuwongolera bwino kuyaka : Mpweya wotentha pang'ono umakhala ndi kuchuluka kwakukulu, komwe kumawonjezera kuchuluka kwa mafuta omwe amalowa ndipo kumalola kuyaka kwathunthu kwa mafuta, motero kumawonjezera mphamvu (pakuchepa kulikonse kwa 10 ° C kwa kutentha kwa mpweya wopanikizika, mphamvu imawonjezeka ndi 3%-5%).
Youdaoplaceholder0 Chepetsani kuphulika ndi kutulutsa mpweya woipa: Mpweya wotentha kwambiri umayambitsa kuwonongeka kwa mpweya, pomwe kuzizira kumachepetsa kutulutsa mpweya wa NOx ndi zinthu zina zoipitsa mpweya.
Mtundu ndi momwe imagwirira ntchito
Ma Intercoolers amagawidwa m'njira ziwiri zazikulu zoziziritsira:
Youdaoplaceholder0 Yoziziritsidwa ndi mpweya : Imagwiritsa ntchito mpweya womwe umapangidwa ndi galimoto ikamayenda kuti ichotse kutentha. Nthawi zambiri imayikidwa kutsogolo kwa galimoto kapena pafupi ndi radiator. Ili ndi kapangidwe kosavuta komanso kotsika mtengo, koma imakhudzidwa kwambiri ndi kutentha kwa malo ozungulira.
Youdaoplaceholder0 Yoziziritsidwa ndi madzi : Imazizira kudzera mu kayendedwe ka injini yoziziritsira, zomwe zimapangitsa kuti kutentha kuzikhala kofanana. Ndi yoyenera magalimoto omwe ali ndi malo ochepa (monga ena omwe amagwira ntchito bwino kwambiri), koma nthawi zambiri kuziziritsa kumakhala kochepa poyerekeza ndi komwe kumaziziritsidwa ndi mpweya.
Zipangizo ndi Kapangidwe
Youdaoplaceholder0 Zipangizo : zambiri zimapangidwa ndi aluminiyamu chifukwa cha kulemera kwake kopepuka komanso kutentha kwake kwabwino kwambiri.
Kapangidwe ka Youdaoplaceholder0: Mkati mwake muli machubu ndi zipsepse zokhuthala, zomwe zimayamwa ndi kutulutsa kutentha pamene mpweya ukuyenda m'machubu.
Zolemba zosamalira ndi kusintha
Kuyeretsa kwa Youdaoplaceholder0: Muzitsuka fumbi lakunja nthawi zonse (pewani kupopera ndi mfuti yamadzi yothamanga kwambiri) ndipo yang'anani mkati mwa fumbilo ngati latsekeka.
Youdaoplaceholder0 Malangizo osinthira :
Sankhani kukula koyenera kuti muyeretse bwino kuziziritsa ndi kutayika kwa mphamvu;
Paipi iyenera kufupikitsidwa momwe mungathere ndikuyisunga molunjika kuti muchepetse kukana kwa mpweya.
Chitoliro cha payipi yotulutsira madzi chiyenera kukhala chokhuthala pafupifupi 10% kuposa payipi yolowera madzi kuti chiwongolere kuyenda bwino kwa madzi.
Zochitika zogwira ntchito
Mainjini okhala ndi turbocharger okha ndi omwe amafunika kukhala ndi ma intercooler, pomwe mainjini okhala ndi mpweya wachilengedwe safuna chipangizochi chifukwa cha kutentha kochepa kwa mpweya.
Chepetsani kutentha kwa mpweya wopanikizika kuti muwonjezere mphamvu ndi magwiridwe antchito a injini
Ntchito yaikulu: Kuziziritsa mpweya wopanikizika
Choziziritsira mpweya ndi gawo lofunika kwambiri la injini zokhala ndi turbocharger kapena supercharged, zomwe zili pakati pa turbocharger ndi intake manifold. Ntchito yake yayikulu ndikuziziritsa mpweya wotentha kwambiri womwe umakanikizidwa ndi turbocharger (wokhala ndi kutentha mpaka 80-200℃), ndikuchepetsa kutentha kwa mpweya wolowa kudzera mu kusinthana kwa kutentha, potero:
Youdaoplaceholder0 Kuonjezera kuchuluka kwa mpweya: Ukazizira, kuchuluka kwa mpweya kumachepa ndipo mpweya umachuluka, zomwe zimapangitsa kuti injini igwire bwino ntchito.
Youdaoplaceholder0 Wonjezerani mphamvu yotulutsa : Zoyesera zikusonyeza kuti pa kutentha kulikonse kwa 10 ° C komwe kumatsika mpweya wopanikizika, mphamvu ya injini imawonjezeka ndi 3% mpaka 5%.
Konzani magwiridwe antchito ndi kudalirika kwa injini
Youdaoplaceholder0 Chepetsani kutentha : Mpweya wolowa kutentha kwambiri umawonjezera kutentha m'chipinda choyaka injini. Choziziritsira chimazizira kuti chisagwedezeke, kusintha kwa mutu wa silinda ndi mavuto ena.
Youdaoplaceholder0 Kuchepetsa mpweya woipa: Mpweya wozizira umayaka kwambiri, zomwe zimachepetsa nayitrogeni oxide (NOx) ndi utsi wakuda.
Youdaoplaceholder0 Imathandizira kuchepetsa mafuta: Mpweya wozizira umasakanikirana bwino ndi mafuta, umathandiza kuti kuyaka kugwire bwino ntchito komanso kuchepetsa kugwiritsa ntchito mafuta.
Kusinthasintha kwapadera kwa chilengedwe
M'malo okwera kwambiri, ma intercooler amalola kugwiritsa ntchito ma compressor okhala ndi chiŵerengero chapamwamba cha kupanikizika kuti athetse kutayika kwa mphamvu komwe kumachitika chifukwa cha mpweya wochepa komanso kukulitsa kusinthasintha kwa mphamvu ya galimotoyo.
Kusiyana kwa mitundu ndi kapangidwe
Youdaoplaceholder0 Yoziziritsidwa ndi mpweya (yoziziritsa mpweya) : Imagwiritsidwa ntchito kwambiri m'magalimoto onyamula anthu, imaziziritsa mpweya wopanikizika ndi mpweya wakunja. Ili ndi kapangidwe kosavuta koma imakhudzidwa kwambiri ndi kutentha kwa malo ozungulira.
Youdaoplaceholder0 Yoziziritsidwa ndi madzi : Imachotsa kutentha kudzera mu choziziritsira, imagwira ntchito bwino koma ndi yokwera mtengo, ndipo imagwiritsidwa ntchito kwambiri m'mamodeli ogwira ntchito kwambiri.
Youdaoplaceholder0 Overhead intercooler (monga Subaru Impreza): imafupikitsa mphamvu yolowera koma imakhala ndi mphamvu yochepa yotaya kutentha, ndipo ndi yabwino kwambiri poyendetsa mphamvu ndi kugwiritsa ntchito mafuta.
Kulephera kwa Youdaoplaceholder0: Ngati intercooler ikutuluka, imayambitsa kuchepa kwa mphamvu, kuchuluka kwa mafuta omwe amagwiritsidwa ntchito, komanso kuwonongeka mwachangu chifukwa cha tinthu ta mchenga tomwe timalowa mu silinda.
Ngati pakufunika kukonza bwino kapangidwe kake, chisamaliro chiyenera kuperekedwa ku miyezo ya zinthu (monga GB 3880 ya mbale za aluminiyamu) ndi zofunikira pakupanga pamwamba.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&750 zolandiridwa kugula.
