Kodi sensa ya camshaft ya galimoto ndi chiyani?
Youdaoplaceholder0 Camshaft Position Sensor (CPS) ndi chipangizo chomwe chimagwiritsidwa ntchito kusonkhanitsa zizindikiro za malo a camshaft ndipo chimagwiritsidwa ntchito makamaka mumakina oyang'anira injini. Ntchito zake zazikulu zimaphatikizapo kulowetsa zizindikiro za malo a camshaft ku unit yowongolera zamagetsi (ECU) kuti adziwe nthawi yoyatsira ndi kuyika mafuta, kuthandiza ECU kuzindikira pakati pa cylinder 1 compression top dead kuti ikwaniritse kuwongolera kotsatizana kwa jekeseni wa mafuta, kuwongolera nthawi yoyatsira ndi kuwongolera kuyeretsa .
Malo oyika
Sensa ya camshaft nthawi zambiri imayikidwa kumapeto kwa chivundikiro cha camshaft, moyang'anizana mwachindunji ndi kutsogolo kwa ma camshaft olowera ndi otulutsa mpweya. Kukhazikitsa kumeneku kumaonetsetsa kuti sensayo imagwira molondola chizindikiro cha malo a camshaft ndikuchitumiza ku ECU.
Mfundo yogwirira ntchito
Masensa a Camshaft amagwiritsa ntchito mphamvu ya magnetoelectric kapena Hall effect kuti azindikire malo ndi liwiro lozungulira la camshaft. Mwachitsanzo, sensa ya magnetoelectric camshaft position imawerengera malo ndi liwiro la camshaft pozindikira kusintha kwa mphamvu yomwe imayambitsa mu sensa coil yopangidwa ndi zinthu zamaginito pamene camshaft ikuzungulira .
Njira yodziwira vuto
Mukayang'ana sensa ya camshaft, mutha kudziwa ngati ikugwira ntchito bwino mwa kuchotsa pulagi yake ndikuyatsa switch yoyatsira, ndikugwiritsa ntchito cholembera cha nyali yoyesera kuyesa mawaya atatu (waya wamagetsi, waya wa chizindikiro ndi waya wapansi). Ngati magetsi a chizindikiro amasiyana pakati pa 0 ndi 5 volts, sensa ikugwira ntchito bwino. Kupanda kutero, sensa ikhoza kuwonongeka .
Kulephera kwa sensa ya camshaft ya galimoto kumaonekera kwambiri ngati kuyamba kovuta, liwiro losakhazikika, kuthamanga kofooka, kugwiritsa ntchito mafuta ambiri, kuwala kolakwika nthawi zonse, kungaphatikizeponso kugwedezeka kwa injini, kugwedezeka, kuyima kwa galimoto yotentha, ndi zina zotero. Zizindikirozi zimachitika chifukwa cha zizindikiro zachilendo za sensa, zomwe zimalepheretsa ECU kuwongolera bwino nthawi yoyatsira ndi nthawi yoperekera mafuta, motero zimakhudza magwiridwe antchito onse a injini.
Youdaoplaceholder0 Mawonetseredwe a kulephera kwapakati
Youdaoplaceholder0 Kuvuta poyambitsa : Chifukwa cha vuto la nthawi yoyatsira moto, zingatenge kuyesera kangapo kuti muyambe kapena kulephera kuyamba konse. Nthawi zina, crankshaft reverse rotation ndi intake manifold backfire zimawonetsedwa.
Youdaoplaceholder0 Kusakhazikika kwa IDLE : Kugwedezeka kosazolowereka kwa injini, kusinthasintha koonekeratu kwa liwiro la injini, mofanana ndi silinda yomwe yasowa, ndipo nthawi zina zimayambitsa kugwedezeka.
Youdaoplaceholder0 Dynamic anomaly :
Kuthamanga kofooka komanso kuyankha pang'onopang'ono, vutoli likhoza kuipiraipira kuposa 2500rpm
Pali kugwedezeka kosiyana panthawi yoyendetsa galimoto, makamaka mukathamanga kapena mukamachedwetsa liwiro
Youdaoplaceholder0 Kutsika kwachuma :
Kugwiritsa ntchito mafuta kwawonjezeka ndi 10%-30% chifukwa cha kulephera kwa kulamulira kuchuluka kwa mafuta omwe amalowa m'malo mwake.
Mpweya woipa umachepa, chitoliro chotulutsa utsi nthawi zambiri chimakhala ndi utsi wakuda
Chenjezo la Cholakwika cha Youdaoplaceholder0: Kuwala kwa injini kumakhalabe koyaka, ndipo makina a OBD nthawi zambiri amalemba khodi ya mndandanda wa P0340-P0344.
Zizindikiro ndi zoopsa za Youdaoplaceholder0
Youdaoplaceholder0 Injini yotentha ikuima: Injiniyo ikhoza kuyima mwadzidzidzi ikatenthedwa ndipo ikufunika kuyambiranso kuti izigwira ntchito
Kuwonongeka kwa zigawo za Youdaoplaceholder0: Kulephera kwa nthawi yayitali kudzafulumizitsa kuwonongeka kwa zigawo monga ma pistoni ndi makoma a silinda, zomwe zidzafupikitsa nthawi ya injini.
Youdaoplaceholder0 Kuopsa kwa chitetezo : Kulephera kwa mphamvu kapena kuchepetsa mphamvu mukayendetsa galimoto (kusinthasintha) kumawonjezera mwayi wa ngozi zadzidzidzi
Masensa a malo a camshaft yamagalimoto nthawi zambiri amakhala amodzi kapena awiri, kutengera kapangidwe ka injini
Chiwerengero cha masensa a camshaft m'magalimoto chimasiyana malinga ndi kapangidwe ka injini ndi zofunikira pakugwira ntchito, ndipo chimagawidwa makamaka m'mikhalidwe iwiri iyi:
Youdaoplaceholder0 Kapangidwe ka sensa imodzi
Kawirikawiri imapezeka m'mainjini oyambira kapena machitidwe omwe amangochita kusintha kwa nthawi pa ma valve olowera (monga mitundu ina yomwe imagwiritsa ntchito ukadaulo wa VVT). Masensa nthawi zambiri amayikidwa kutsogolo kwa camshaft yolowera ndipo amagwiritsidwa ntchito kupereka chizindikiro chachikulu chowongolera kuyaka kwa ECU.
Mwachitsanzo: Magalimoto ena amasintha nthawi ya valavu yolowera kudzera mu sensa imodzi yokha, pomwe valavu yotulutsa utsi imakhalabe yokhazikika.
Youdaoplaceholder0 Kapangidwe ka sensa ziwiri
Kawirikawiri zimawoneka m'makina omwe nthawi imodzi amawongolera nthawi yosinthasintha ya ma valve olowetsa ndi otulutsa mpweya (monga ukadaulo wa VVT wapawiri). Masensa awiriwa amafanana motsatana ndi ma camshaft olowetsa ndi otulutsa mpweya kuti akwaniritse kusintha kolondola kwa gawo.
Mwachitsanzo, injini ya EA888 ya m'badwo wachitatu imagwiritsa ntchito masensa awiri (imodzi yolowetsa ndi ina yotulutsa utsi).
Chidule cha mfundo zazikulu za Youdaoplaceholder0:
Chiwerengero cha masensa chikugwirizana ndi zovuta zaukadaulo za injini. Ma model oyambira nthawi zambiri amakhala ndi sensa imodzi, pomwe ma model apamwamba kapena ogwirira ntchito nthawi zambiri amakhala ndi awiri.
Amadziwikanso kuti "synchronous signal sensor" kapena "Cylinder discrimination and Positioning device", ntchito yaikulu ya zonsezi ndi kutumiza chidziwitso cha camshaft phase ku ECU.
Malo oyikapo ayenera kukhala moyang'anizana ndi gudumu la chizindikiro; apo ayi, kusonkhanitsa deta molondola sikungatheke.
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 MG&MAXUSzida zamagalimoto zalandiridwa kugula.
