Kodi msonkhano wa camshaft wotulutsa utsi wa magalimoto ndi chiyani?
Kusonkhanitsira camshaft ya utsi wa galimoto ndi gawo lofunika kwambiri la sitima ya valve ya injini, makamaka yomwe imayang'anira nthawi yotsegulira ndi kutseka ma valve kuti zitsimikizire kuti utsi wa utsi ukuyenda bwino.
Ntchito yaikulu
Mwa kusintha nthawi yotsegulira ma valavu ndikuwongolera mphamvu ya injini yolowera pansi pa mikhalidwe yosiyanasiyana yogwirira ntchito, zimakhudza mwachindunji kutulutsa mphamvu ndi kusunga mafuta. Mwachitsanzo, kutseka ma valavu pasadakhale mukamayendetsa pa liwiro lotsika kungachepetse kutuluka kwa mpweya wotulutsa utsi, pomwe kuchedwetsa kutseka mukamayendetsa pa liwiro lalikulu kungawonjezere magwiridwe antchito a mphamvu.
Kapangidwe ka kapangidwe kake
Imakhala ndi stator, rotor, control oil passage ndi actuator, ndipo imayang'anira kusintha kwa gawo kudzera mu kuthamanga kwa mafuta. Kapangidwe kake kayenera kuganizira mphamvu ndi kulondola, ndipo zinthuzo makamaka ndi chitsulo chosakanikirana kuti chipirire kugwira ntchito mwachangu komanso mphamvu yayikulu.
"Ntchito yaukadaulo"
Mitundu ina imagwiritsa ntchito ukadaulo wa AVS (Variable Valve Lift), womwe umasintha ma angles otsegulira ndi otsekera a ma valve kudzera mu unit yowongolera zamagetsi, zomwe zimapangitsa kuti injini izigwira bwino ntchito. Mwachitsanzo, Volkswagen/Audi imapeza mphamvu yotulutsa mphamvu yamagetsi pa liwiro lotsika kudzera mu kusintha kwa ma valve amagetsi a camshaft.
Ntchito ya camshaft yotulutsira utsi wa galimoto ndikuwongolera nthawi yotsegulira ndi kutseka kwa valavu yotulutsira utsi, kuonetsetsa kuti mpweya wotulutsira utsi ukutuluka mwachangu kuchokera ku silinda, zomwe zimakhudza mwachindunji magwiridwe antchito a injini komanso momwe mpweya wotulutsira utsi umagwirira ntchito.
Ntchito yaikulu
Kudzera mu kayendedwe kozungulira ka camshaft, ma valve otulutsa utsi amayendetsedwa kuti atsegule ndi kutseka motsatizana, kuwongolera nthawi, liwiro ndi kukweza kwa mpweya wotulutsa utsi. Izi zimagwirizanitsidwa ndi kayendedwe ka pisitoni kuti zitsimikizire kuti injini ikugwira ntchito bwino.
Udindo waukulu
Youdaoplaceholder0 Konzani bwino utsi wotuluka: Onetsetsani kuti mpweya wotuluka umatulutsidwa panthawi yoyenera, kuchepetsa mphamvu ya mpweya wotsala pa kutentha koyaka, ndikuwonjezera mphamvu yotulutsa.
Youdaoplaceholder0 Chepetsani kuipitsidwa kwa mpweya woipa: Yang'anirani bwino momwe mpweya woipa umatulutsidwira kuti muchepetse kutulutsa mpweya woipa womwe sunatenthe bwino, zomwe zingakuthandizeni kukwaniritsa zofunikira zoteteza chilengedwe.
Youdaoplaceholder0 imasintha malinga ndi mikhalidwe yosiyanasiyana yogwirira ntchito : Sinthani magawo a valavu (monga kukweza) malinga ndi kuchuluka kwa injini kuti muchepetse mafuta komanso magwiridwe antchito a mphamvu.
Kukulitsa ukadaulo
Ma camshaft a mitundu ina amaphatikizanso ukadaulo wa variable valve timing (VVT) kapena lift (VVL), zomwe zimapangitsa kuti injini izigwira bwino ntchito mwa kusintha mawonekedwe a CAM.
Zolakwika mu msonkhano wa camshaft wa magalimoto nthawi zambiri zimawonetsedwa motere:
Youdaoplaceholder0 Kuvuta poyambira : Kuvuta poyatsira kapena kulephera kuyamba, ECU silingathe kupeza chizindikiro cha malo a camshaft, zomwe zimapangitsa kuti pakhale chisokonezo pa nthawi yoyatsira
Youdaoplaceholder0 Kuchepa kwa mphamvu : kuthamanga kofooka, kugwedezeka kosagwira ntchito, kuyaka kosakwanira komwe kumabweretsa kutulutsa mphamvu kosazolowereka kwa silinda
Youdaoplaceholder0 Kuchuluka kwa kugwiritsa ntchito mafuta: ECU imagwiritsa ntchito magawo okhazikika ogwiritsira ntchito mafuta, zomwe zimapangitsa kuti mafuta asagwiritsidwe ntchito bwino
Youdaoplaceholder0 Kuwonongeka kwa mpweya wotulutsa mpweya: mpweya wochuluka wotulutsa utsi, utsi wakuda wotulutsa utsi, dongosolo la OBD limayambitsa khodi yolakwika (monga P0014)
Zomwe zimayambitsa
Kulephera kwa valavu ya solenoid ya Youdaoplaceholder0 : Kuwonongeka kwa valavu ya solenoid ya actuator ya camshaft yotulutsa utsi kungayambitse kulephera kwa malamulo (vuto lofala, lomwe limayambitsa mavuto opitilira 60%)
Youdaoplaceholder0 Mafuta/kuipitsidwa kosakwanira : Kupanikizika kosakwanira kwa mafuta kapena kulowerera kosayera kumakhudza dongosolo losinthasintha la nthawi
Youdaoplaceholder0 Kulephera kwa pulagi/mzere wotayirira : Kusungunuka kapena kumasuka kwa pulagi ya valavu ya solenoid kumayambitsa kusokonezeka kwa kutumiza kwa chizindikiro
Kuwonongeka kwa sprocket ya Youdaoplaceholder0 : Kuwonongeka kwa sprocket ya camshaft VVT actuator kudzakhudza kukhazikika kwa liwiro la injini
Kulephera kwa sensa ya Youdaoplaceholder0: Vuto la sensa yoyipa ya camshaft kapena kuyika kwake lingayambitsenso zizindikiro zofanana
Yankho
Youdaoplaceholder0 Yang'anani valavu ya solenoid : werengani khodi yolakwika ndi chida chodziwira matenda, yesani mtengo wotsutsa wa valavu ya solenoid (nthawi zambiri pafupifupi 0.13Ω), ndikubwezeretsani gawo lowonongeka
Youdaoplaceholder0 Tsukani sensa : Chotsani sensa ya camshaft kuti muyeretse madontho a mafuta kapena zinthu zakunja. Mukayikanso, onetsetsani kuti mpatawo ndi woyenera
Youdaoplaceholder0 Yang'anani dongosolo la nthawi : tsimikizirani ngati nthawi ya valavu ndi yolondola. Ngati kuli kofunikira, sinthani unyolo kapena sinthani chotenthetsera
Youdaoplaceholder0 Onjezani mafuta a injini : Onetsetsani kuti mulingo wa mafuta ndi wabwinobwino komanso wopanda zinyalala, ndipo sinthani fyuluta yamafuta nthawi zonse
Youdaoplaceholder0 Kusamalira akatswiri : Pakakhala mavuto okhudzana ndi kukhazikitsa masensa kapena mawaya, ayenera kuthetsedwa ndi akatswiri
Ngati kuwala kwa cholakwa kukupitirirabe kapena zizindikiro sizikuchepa, tikukulimbikitsani kuti mulumikizane ndi bungwe losamalira akatswiri kuti mukayang'ane mwachangu.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
