Kodi gawo la sensor yamagalimoto ya camshaft ndi chiyani
Camshaft position sensor imagwira ntchito yofunika kwambiri mu injini yamagalimoto, ntchito yayikulu ndikutolera chizindikiro cha camshaft ndikuyika pamagetsi owongolera zamagetsi (ECU) kuti mudziwe nthawi yoyatsira ndi nthawi yobaya mafuta. Pozindikira malo ozungulira a camshaft, sensa imazindikira nthawi yotsegula ndi yotseka ya valve, motero imakwaniritsa kuwongolera bwino kwa injini. pa
Mfundo yogwirira ntchito ya camshaft position sensor imachokera ku electromagnetic induction kapena photoelectric induction technology. Pamene camshaft ikuzungulira, sensa imazindikira phokoso kapena notch mu camshaft ndikupanga chizindikiro chamagetsi chofananira. Atalandira zizindikiro izi, ECU amaona poyatsira nthawi ndi jekeseni mafuta nthawi mawerengedwe ndi processing, kuti tikwaniritse kulamulira molondola injini. pa
Kulondola komanso kudalirika kwa masensa amtundu wa camshaft ndikofunikira kwambiri pakugwira ntchito kwa injini komanso kuchepa kwamafuta. Sensa ikalephera, imatha kuyambitsa kuyatsa molakwika, kuchepa kwamafuta amafuta, mwinanso injini yomwe siigwira bwino ntchito. Chifukwa chake, kuyang'anira nthawi zonse ndikukonza sensor ya camshaft ndikofunikira kwambiri.
camshaft sensa ndi gawo lofunikira lagalimoto, lomwe limagwiritsidwa ntchito kwambiri kuzindikira malo a camshaft ndi liwiro, kuwonetsetsa kuti injini ikuyenda bwino. Camshaft Sensor, yomwe imadziwikanso kuti Camshaft Position Sensor (CPS) kapena Cylinder Identification Sensor (CIS), ntchito yake yaikulu ndikusonkhanitsa zizindikiro za camshaft ya valve. Zizindikirozi zimaperekedwa mu Unit Control Control Unit (ECU). Kuchokera pazizindikirozi, ECU imatha kuzindikira psinjika TDC ya silinda 1 pakuwongolera jekeseni wamafuta motsatizana, kuwongolera nthawi yoyatsira ndi kuwongolera kutentha.
Kapangidwe ndi mfundo ntchito
Pali mitundu yambiri ya masensa a camshaft, kuphatikizapo photoelectric ndi magnetic induction. Photoelectric sensor imapangidwa makamaka ndi ma sign disk, jenereta ya ma signal ndi ogawa, ndipo imapanga chizindikiro kudzera mu diode yotulutsa kuwala ndi transistor ya photosensitive. Mtundu wa maginito opangira maginito umagwiritsa ntchito mphamvu ya Hall kapena mfundo ya kulowetsa maginito kuti ipange ma siginecha, omwe nthawi zambiri amagawidwa mu mtundu wa Hall ndi mtundu wa magnetoelectric.
Kuyika malo
Sensa ya camshaft position nthawi zambiri imayikidwa kumapeto kwa chivundikiro cha camshaft, moyang'anizana ndi kutsogolo kwa camshaft ndi kutulutsa mpweya. Mapangidwe awa amatsimikizira kuti sensa imatha kusonkhanitsa molondola chizindikiro cha camshaft.
Kuchita zolakwika ndi zotsatira zake
Ngati sensa ya camshaft ikulephera, zizindikiro zodziwika bwino zimaphatikizapo kuvutika kuyambitsa galimoto, kuvutika kwa refueling kapena kuyimitsa pamene kutentha, kuwonjezereka kwa mafuta, mphamvu zosakwanira komanso kuthamanga kosauka. Zizindikirozi zimayamba chifukwa cha kulephera kwa ECU kuwongolera molondola jakisoni wamafuta ndi nthawi yoyatsira.
Ngati mukufuna kudziwa zambiri, pitilizani kuwerenga zolemba zina patsamba lino!
Chonde tiyimbireni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. adadzipereka kugulitsa zida zamagalimoto za MG&750 zolandilidwa kugula.
