Kodi chowongolera gawo la galimoto ndi chiyani?
Chowongolera gawo la magalimoto ndi chipangizo chomwe chimasintha nthawi ya valavu posintha Angle ya gawo ndipo chimagwiritsidwa ntchito makamaka kukonza magwiridwe antchito a injini. Ntchito yake yayikulu ndikusintha nthawi yotsegulira ndi kutseka mavalavu malinga ndi liwiro la injini ndi katundu wake, motero kumawonjezera mphamvu zotulutsa komanso kusunga mafuta.
Kapangidwe ndi mfundo yogwirira ntchito
Chowongolera magawo nthawi zambiri chimakhala ndi thupi lowongolera magawo, sprocket ya camshaft, mota, ndi zina zotero, ndipo gawo la camshaft limasinthidwa kudzera mu dongosolo la hydraulic kapena motor drive. Mwachitsanzo, chowongolera magawo amagetsi chimalumikiza camshaft ndi sprocket kudzera mu njira yosinthira liwiro la axis atatu, ndipo mota imayendetsa kusintha kwa kusiyana kwa magawo kuti ikwaniritse kusintha kwa nthawi ya valve.
Zochitika zazikulu zogwiritsira ntchito
Amagwiritsidwa ntchito makamaka mu makina osinthasintha a valve timing systems (monga VVT), omwe amakwaniritsa zofunikira pamikhalidwe yosiyanasiyana yogwirira ntchito ya injini. Mwachitsanzo, chowongolera gawo la intake chingathandize kukonza bwino kuyaka, pomwe chowongolera gawo la utsi chingathandize kuchepetsa kusokoneza kwa mpweya wotuluka.
Ma modulators a gawo la magalimoto amagwiritsidwa ntchito makamaka kusintha magawo a resonant circuit mwa kusintha chizindikiro, zomwe zimapangitsa kuti kusintha kwa gawo mu chizindikiro chonyamuliracho kupange mafunde osinthika. Amagwiritsidwa ntchito makamaka posintha chizindikiro ndi kutumiza mauthenga m'makina amphamvu.
Ntchito yaikulu
Youdaoplaceholder0 Kusintha kwa chizindikiro : Mwa kusintha magawo monga inductance ndi capacitance ya resonant circuit, gawo la chizindikiro chonyamulira limasinthidwa kuti likwaniritse kusintha kwa chizindikiro.
Youdaoplaceholder0 circuit control : Imagwiritsidwa ntchito m'makina amphamvu kuti ilamulire kukhazikika kwa magetsi, mwachitsanzo, kusunga magetsi otulutsa a jenereta pafupifupi mtengo wovomerezeka (monga 14V) kuti zitsimikizire kuti zida zamagetsi zikugwira ntchito bwino.
Ntchito yoteteza ya Youdaoplaceholder0 : Pamene mphamvu yowonjezera ya chaji yapezeka kapena kuyenda mobwerera m'mbuyo kukachitika, dera limadulidwa mwachangu kuti batire isadzazidwe kwambiri kapena kuwonongeka kwa zida.
Kusiyana ndi chowongolera magalimoto
Oyang'anira magawo amayang'ana kwambiri pa kukonza ma signal ndi kuwongolera ma circuit, pomwe owongolera magalimoto amadzipereka kwambiri ku kukhazikika kwa magetsi ndi chitetezo cha overcurrent mumagetsi. Zochitika za kugwiritsa ntchito ziwirizi ndizosiyana, koma zonse ziwiri zimakhudza malamulo a ma circuit parameter ndi njira zotetezera.
Mfundo yogwirira ntchito ya automotive phase regulator imadalira kwambiri hydraulic system kapena motor drive. Mwa kusintha malo pakati pa camshaft ndi crankshaft, nthawi ya valavu (monga nthawi yomwe mavalavu amatsegulidwa ndi kutsekedwa) imasinthidwa.
Mfundo ya ma modulators a hydraulic phase
Tengani chitsanzo cha dongosolo la OCV VVT lomwe lili m'mbali. Zigawo zake zazikulu ndi gawo lowongolera ndi valavu yowongolera mafuta (OCV). Gawo lowongolera limakonza malo pakati pa camshaft sprocket ndi rotor kudzera mu chipinda cha hydraulic, ndipo valavu yowongolera mafuta imawongolera kuthamanga kwa hydraulic malinga ndi momwe injini imagwirira ntchito. Pamene katundu wachepa, tsekani valavu yolowera pasadakhale; pamene katundu wakwera, yesani kutseka valavu yolowera kuti muwongolere mphamvu yotulutsa.
Mfundo ya wowongolera gawo lamagetsi
Chowongolera gawo lamagetsi chimagwiritsa ntchito kapangidwe ka ma axis atatu: axis yoyamba imalumikizidwa ku camshaft, axis yachiwiri imayendetsedwa ndi mota, ndipo axis yachitatu imalumikizidwa ku sprocket. Mota imakwaniritsa malamulo a gawo posintha kusiyana kwa liwiro. Pamene Angle ya nthawi yabwino yakhazikika, ma axe atatu amazungulira motsatizana. Posintha gawo, mota imayendetsa shaft kuti ifulumizitse kapena ichepe.
Mitundu yonse iwiri imafuna masensa kuti aziyang'anira malo a crankshaft ndi camshaft, ndikuwongolera zochita za actuator kudzera mu ECU.
Zolakwika mu chowongolera magalimoto (nthawi zambiri zimatanthauza chowongolera jenereta) zingayambitse magetsi osakhazikika, kuyambitsa kovuta ndi mavuto ena. Zotsatirazi ndi zizindikiro ndi zifukwa zake:
Zochitika zodziwika bwino
Youdaoplaceholder0 voltage anomaly
Kupanga mphamvu zambiri kungayambitse kudzaza batri mopitirira muyeso, ndipo mphamvu yamagetsi ikhoza kupitirira 14V, zomwe zimapangitsa kuti batri ikule msanga komanso kuwonongeka. Ngati mphamvu yamagetsi siili yokwanira, mphamvu yamagetsi ikhoza kukhala yotsika kuposa 10V, zomwe zimapangitsa kuti kuyambika kukhale kovuta komanso kuthamangitsidwa pang'ono.
Zolakwika zokhudzana ndi batri za Youdaoplaceholder0
Ngati kuwala kwa batri sikwabwinobwino (kumayatsidwa nthawi zonse kapena kung'anima), nthawi ya batri imafupikitsidwa. Pa milandu yoopsa, sikungathe kusunga magetsi.
Kuchepa kwa magwiridwe antchito a injini ya Youdaoplaceholder0
Ngati injini igwedezeka, ithamanga mofooka kapena ikaima mwachindunji, iyenera kuyang'aniridwa ndikukonzedwa nthawi yomweyo.
Chifukwa cha vuto
Kusinthasintha kwa voliyumu ya Youdaoplaceholder0
Mphamvu yotulutsa ya jenereta yosakhazikika (monga kusinthasintha kwa liwiro la injini ya dizilo ndi kusintha kwakukulu kwa katundu) zimapangitsa kuti chowongolera chizisinthasintha pafupipafupi, zomwe zimapangitsa kuti zinthu ziyambe kukalamba mwachangu.
Youdaoplaceholder0 Kulemera kwambiri kwa makina
Kugwira ntchito mopitirira muyeso kwa nthawi yayitali (monga kungokhala chete kapena kutayikira kwa mafuta m'dera la jenereta) kumawonjezera ntchito ya wowongolera.
Youdaoplaceholder0 gawo lokalamba
Ma transistors amkati mwa chowongolera (monga ma FET, ma transistors a Darlington) amasweka kapena kutsegulidwa, zomwe zimapangitsa kuti mphamvu yamagetsi itayike.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
