Kodi sensa ya camshaft yamagalimoto ndi chiyani?
Youdaoplaceholder0 Chojambulira malo cha camshaft yamagalimoto (CPS) ndi chipangizo chomwe chimagwiritsidwa ntchito kuzindikira malo ndi ngodya ya camshaft, zomwe zimapereka zizindikiro ku ECU (Engine Control Unit) kuti ziwongolere magawo ofunikira a injini monga nthawi yoyatsira, nthawi yopangira mafuta, ndi kuwongolera kuphulika kwa injini.
Ntchito yaikulu
Kuyika silinda: Pozindikira malo a camshaft, compression top dead center (BTDC) ya piston yoyamba ya silinda imatsimikiziridwa kuti ikwaniritse bwino kulowetsa mafuta ndikuwongolera kuyaka.
Chizindikiro chogwirizana: Monga chizindikiro chachikulu chowongolera kuyatsa, chimatsimikizira kuti silinda iliyonse ya injini ikugwira ntchito motsatizana.
Mfundo yogwirira ntchito
Kupanga zizindikiro: Sensa ili ndi diode yotulutsa kuwala (LED) ndi phototransistor mkati. Kudzera m'mabowo otumiza kuwala ndi mbali zotchinga kuwala za disk ya chizindikiro, zizindikiro za pulse zapamwamba ndi zochepa zimapangidwa motsatizana.
Mtundu wa chizindikiro
Chizindikiro cha Ne: Chimawonetsa malo a crankshaft ndipo chimapanga ma pulses 360 pa kuzungulira kulikonse.
Chizindikiro cha G: Chimawonetsa malo a camshaft, ndikupanga ma pulses 6 pa kuzungulira kulikonse (kofanana ndi ngodya yozungulira ya crankshaft ya 120°).
Mitundu yodziwika bwino
Mtundu wa Photoelectric: Kugwiritsa ntchito zinthu zomwe zimazindikira kuwala kuti zizindikire mabowo otumiza kuwala a disk ya chizindikiro.
Mtundu wa maginito wolowetsa: Umagawidwa m'magulu awiri: Hall type (fixed amplitude signal) ndi magnetoelectric type (matalikidwe amasiyana malinga ndi liwiro lozungulira).
Zotsatira zolakwika
Zizindikiro za vuto: Zingayambitse kulephera kwa injini kuyatsa, mphamvu kuchepa, kugwiritsa ntchito mafuta kuchuluka kapena kugogoda.
Mitundu yanthawi zonse: Mwachitsanzo, Audi Q5 ya 2015 ili ndi ma camshaft awiri ndipo imafuna masensa awiri kuti azitha kuyang'anira mosiyana.
Pamene sensa ya camshaft ya galimoto ilephera kugwira ntchito, zizindikiro monga kuvutika kuyatsa, kuchepa kwa mphamvu, kuchuluka kwa mafuta, kugwedezeka kwa thupi, ndi kuwala kochenjeza komwe kumabwera nthawi zambiri kumachitika. Izi zimaonekera motere:
Youdaoplaceholder0 Kuyambitsa kosazolowereka : Injini yalephera kuyatsa kapena imakhala yovuta kuyiyambitsa. Zingatenge kuyesera kangapo kuti ipambane. Izi zitha kuchitika m'malo ozizira komanso otentha a injini.
Youdaoplaceholder0 Vuto la mphamvu yotulutsa : kuthamanga kofooka, kuyankha pang'onopang'ono kwa throttle, komanso kusowa kwa mphamvu poyendetsa, ngakhale kutsatiridwa ndi kugwedezeka kwa thupi.
Youdaoplaceholder0 Kuwonongeka kwa ndalama zosungira mafuta : Kugwiritsa ntchito mafuta kwawonjezeka kwambiri chifukwa cha kulephera kwa ECU kuwongolera molondola kuchuluka kwa mafuta omwe amalowetsedwa, zomwe zimapangitsa kuti mafuta asayaka bwino.
Youdaoplaceholder0 Kugwira ntchito kosakhazikika : Liwiro la injini silikhazikika ndipo kugwedezeka kumakhala koonekeratu pamene ikugwira ntchito. Kugwedezeka kumawonjezeka pamene katundu wambiri akukwera. Magalimoto ena amatha kukumana ndi kugwedezeka kwa galimoto kapena kuyima mwadzidzidzi akamatenthedwa.
Youdaoplaceholder0 Choyambitsa cholakwika : Nyali ya injini yolakwika pa dashboard (monga ma code a OBD fault P0340-P0344) imakhalabe yoyaka nthawi zonse, kusonyeza kuti makinawo apeza chizindikiro chosazolowereka.
Ngati zizindikiro zomwe zili pamwambapa zichitika, tikukulimbikitsani kuti injini iwunikidwe ndikukonzedwa nthawi yake kuti injini isawonongekenso.
Galimoto ikalephera kugwira ntchito bwino ngati camshaft position sensor, imatha kulephera kuyenda bwino. Kuyendetsa mokakamiza kungayambitse kuwonongeka kwakukulu kwa injini komanso zoopsa zina monga kuyima pamene ikuyendetsa. Kukonza mwachangu kumafunika.
Zotsatira za zolakwika pa mphamvu yoyendetsa galimoto
Sensa ya malo a camshaft ndi gawo lofunika kwambiri la makina owongolera injini, omwe amayang'anira kupereka zizindikiro za gawo la camshaft ku ECU (Electronic Control Unit) kuti iwongolere bwino momwe kuyatsira moto kumayendera, nthawi yopangira mafuta, komanso kuletsa kuphulika. Ikawonongeka, ECU singathe kuzindikira bwino malo a silinda, zomwe zimapangitsa kuti kuyendetsa injini kulephereke komanso galimotoyo isagwire ntchito bwino. Izi zimaonekera bwino ngati:
Youdaoplaceholder0 Zovuta kuyambitsa kapena kulephera kuyambitsa : Sensor ikalephera kugwira ntchito, ECU iyenera kudalira chizindikiro cha malo a crankshaft kuti izindikire momwe camshaft ilili, zomwe zimapangitsa kuti kuyatsa ndi kuyamwa kwa mafuta kuchedwe. Pa nthawi yozizira, kuyesa kangapo kungafunike kapena kulephera kwathunthu kungachitike.
Injini imayima mwadzidzidzi ikayendetsa: Makamaka pamene galimoto ikutentha kapena ikanyamula katundu wambiri, injiniyo imatha kuzimitsa mwadzidzidzi chifukwa cha vuto la kuwongolera, zomwe zimawonjezera chiopsezo cha ngozi.
Youdaoplaceholder0 Mphamvu yochepa yotulutsa : ECU idzalowa mu njira yoteteza zolakwika (njira yotsimphina), kuchepetsa liwiro la galimoto (monga mpaka 80km/h) ndikuletsa ntchito zina, zomwe zimapangitsa kuti liwiro likhale lofooka komanso kukwera mapiri kukhala ovuta.
Zizindikiro zodziwika bwino zomwe zimachitika chifukwa cha vuto la kusowa kwa ntchito
Pambuyo poti sensa ya camshaft yawonongeka, galimotoyo idzawonetsa nthawi yomweyo zinthu zotsatirazi zomwe zikuwonekera, zomwe zimatsimikiziranso kuti kuyendetsa galimoto sikungatheke:
Youdaoplaceholder0 Liwiro losakhazikika lopanda ntchito komanso kugwedezeka kwakukulu : ECU imalephera kugwirizanitsa nthawi yotsegulira ndi kutseka kwa valavu, zomwe zimapangitsa kuti pakhale kusalingana pakati pa kuchuluka kwa mphamvu yolowa ndi yotulutsa mpweya. Injini ili mu mkhalidwe wofanana ndi "silinda yosowa", yokhala ndi kusinthasintha kwakukulu kwa liwiro lozungulira.
Youdaoplaceholder0 Kuwonongeka kwa mafuta osagwiritsidwa ntchito: Nthawi yolakwika yoperekera mafuta imabweretsa kuyaka kosakwanira, zomwe zimapangitsa kuti mafuta agwiritsidwe ntchito ndi 10% mpaka 15%, ndipo utsi wakuda ungatuluke mu chitoliro chotulutsa utsi nthawi yomweyo.
Kuwala kwa cholakwika kumakhalabe koyatsa: dashboard idzawonetsa chenjezo la cholakwika cha injini (monga khodi P0011 kapena P0340), kusonyeza vuto la dongosolo.
Kuopsa koyendetsa galimoto mokakamizidwa
Ngati vutolo silikunyalanyazidwa ndipo galimoto ikupitiriza kuyendetsa, zotsatirapo zoopsa zotsatirazi zingachitike
Kuwonongeka kwa makina a injini ya Youdaoplaceholder0 : Nthawi yoyatsira yolakwika ingayambitse kugogoda kapena kubweza crankshaft. Kugwira ntchito kwa nthawi yayitali kungawononge zigawo zazikulu monga ma pistoni ndi ndodo zolumikizira, zomwe zimawonjezera ndalama zokonzera.
Youdaoplaceholder0 Kulephera kwa dongosolo lotulutsa mpweya : Kuyaka kosakwanira kumayambitsa mpweya wochuluka wa CO ndi HC, zomwe zingatseke chosinthira mphamvu cha njira zitatu ndikuphwanya malamulo oteteza chilengedwe.
Youdaoplaceholder0 Zoopsa za chitetezo zimawonjezeka : Kuyima kapena kusokonekera kwa mphamvu mukamayendetsa galimoto kungakhudze mwachindunji machitidwe monga brake assist ndi steering assist, zomwe zimaika pachiwopsezo chitetezo cha galimoto.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
