Ntchito ya valavu yowongolera sensor ya gawo la galimoto ya camshaft
Ntchito yaikulu ya valavu yowongolera gawo la camshaft sensor ndikuwongolera momwe injini imalowera ndi kusuntha, motero kukonza magwiridwe antchito a injini komanso kusunga mafuta moyenera. Makamaka, valavu yowongolera imakhudza nthawi yotsegulira ndi kutseka kwa valavu posintha ngodya ya gawo la camshaft, zomwe zimakhudza kuchuluka kwa kulowa ndi kutulutsa kwa injini. Lamuloli lingathandize injini kukwaniritsa bwino kwambiri kuyaka komanso kusunga mafuta moyenera pansi pa mikhalidwe yosiyanasiyana yogwirira ntchito.
Mfundo yogwirira ntchito
Ma valve owongolera a sensa ya gawo la Camshaft nthawi zambiri amagwira ntchito ndi owongolera magawo a camshaft. Sensa ikazindikira momwe injini ikuyendera, chizindikirocho chimatumizidwa ku ECU (electronic control unit), ndipo ECU imasintha malo a valavu yowongolera malinga ndi zizindikiro izi, potero imasintha Angle ya gawo la camshaft. Njirayi imachitika mothandizidwa ndi madzi kapena magetsi, zomwe zingasiyane kutengera mtundu ndi kapangidwe kake.
Zotsatira zolakwika
Ngati valavu yowongolera ya camshaft phase sensor yalephera, izi zingayambitse kuchepa kwa magwiridwe antchito a injini, kuchuluka kwa mafuta omwe amagwiritsidwa ntchito, komanso kuwonjezeka kwa mpweya woipa. Mwachitsanzo, ngati valavu yowongolera sisintha Angle ya phase molondola, izi zingayambitse nthawi yolakwika ya valavu, zomwe zimakhudza kuyaka bwino, zomwe zimapangitsa kuti mphamvu yamagetsi isagwire bwino ntchito komanso kuchuluka kwa mafuta omwe amagwiritsidwa ntchito.
Malangizo okonza
Pofuna kuonetsetsa kuti valavu yowongolera ya camshaft phase sensor ikugwira ntchito bwino, tikukulimbikitsani kuti muyang'ane ndikusunga ziwalo zofunikira nthawi zonse. Izi zikuphatikizapo kuyang'ana mtundu wa mafuta a hydraulic system, kuyeretsa kapena kusintha zosefera zotsekeka, komanso kuyang'ana kulumikizana kwamagetsi nthawi zonse. Kuphatikiza apo, pewani kuyendetsa galimoto kwa nthawi yayitali m'malo ovuta kuti muchepetse kuwonongeka kwa valavu yowongolera .
Zizindikiro za kulephera kwa valve yowongolera gawo la camshaft sensor yamagalimoto makamaka ndi izi:
Kuvuta kapena kulephera kuyambitsa : ECU silingathe kupeza chizindikiro cha malo a camshaft, zomwe zimapangitsa kuti nthawi yoyatsira isokonezeke, ndipo injini imakhala yovuta kuyambitsa .
Kugwedezeka kwa injini kapena kutsika kwa mphamvu: cholakwika cha nthawi yoyatsira chomwe chimapangitsa kuti kuyaka kusagwire bwino ntchito, injini ikhoza kugwedezeka nthawi ndi nthawi, kuthamanga kofooka.
Kuchuluka kwa kugwiritsa ntchito mafuta, kuonjezera kuchuluka kwa mpweya woipa: ECU ikhoza kulowa mu "emergency mode", pogwiritsa ntchito magawo okhazikika a injection, zomwe zimapangitsa kuti mafuta asagwiritsidwe ntchito bwino komanso kuti mpweya woipa utuluke kwambiri.
Kuwala kwa cholakwika kumayatsidwa: njira yodziwira vuto yomwe ili mkati mwa chipangizocho (OBD) imazindikira chizindikiro cha sensor chosazolowereka ndikuyambitsa khodi yolakwika (monga P0340).
Kuyima kapena kusakhazikika kwa idle: Pamene chizindikiro cha sensa chasokonezedwa, ECU ikhoza kulephera kusunga liwiro labwinobwino la idle, zomwe zimapangitsa kuti injini iimitse mwadzidzidzi.
Mphamvu yochepa yotulutsa: Mitundu ina imachepetsa mphamvu ya injini kuti iteteze makina.
Zifukwa za kulephera zingakhale ndi:
Sensa yokha yawonongeka: kukalamba kwa zigawo zamagetsi zamkati, kulephera kwa zigawo zoyambitsa maginito, dera lalifupi kapena dera lotseguka.
Kulephera kwa circuit kapena plug: plug imasungunuka kapena kumasuka, harness imasweka, imafupikitsidwa kapena kusweka (monga kutentha kapena makoswe).
Dothi la sensa kapena kulowa kwa mafuta: matope kapena zinyalala zachitsulo zimamangiriridwa pamwamba pa sensa, zomwe zimakhudza kusonkhanitsa kwa chizindikiro.
Vuto lokhazikitsa: kutseguka kosayenera kwa sensa (mwachitsanzo, mtunda pakati pa sensa ndi giya ya camshaft ndi wautali kwambiri), zomangira zokhazikika zomasuka .
Zolephera zina zokhudzana nazo: kusalingana bwino kwa lamba wa nthawi/unyolo, kulephera kwa sensa ya malo a crankshaft, kulephera kwa ECU, kapena kusokoneza kwa maginito.
Njira zoyesera ndi kukonza zikuphatikizapo:
Werengani khodi yolakwika : Gwiritsani ntchito chida chodziwira OBD kuti muwerenge khodi yolakwika (monga P0340) ndikutsimikizira ngati ndi cholakwika cha camshaft sensor .
Yang'anani mawaya ndi pulagi ya sensa: yang'anani kuti pulagiyo ndi yomasuka, yadzimbirika, waya wolumikizidwa sunawonongeke, konzani kapena kusintha ngati pakufunika kutero.
Sensa yoyera: Chotsani sensa ndikuchotsa mafuta pamwamba kapena zinyalala ndi chotsukira cha carburetor (kusamala kuti musawonongeke).
Yesani kukana kwa sensa kapena chizindikiro: Gwiritsani ntchito multimeter kuti muyese ngati kukana kwa sensa kukukwaniritsa muyezo wamanja; Gwiritsani ntchito oscilloscope kuti muone ngati mawonekedwe a mafunde a chizindikiro ndi abwinobwino.
Sinthani sensa: ngati zatsimikizika kuti sensa yawonongeka, sinthani zida zoyambirira kapena zodalirika za mtundu (samalani ndi kutseguka ndi mphamvu yake panthawi yoyika).
Yang'anani dongosolo la nthawi: ngati vuto likugwirizana ndi nthawi (monga mano odumphira lamba wa nthawi), muyenera kubwerezanso kuwunikira chizindikiro cha nthawi.
Chotsani khodi yolakwika ndikuyiyendetsa : chotsani khodi yolakwika mutatha kukonza, ndikuchita mayeso a pamsewu kuti muwone ngati cholakwikacho chachotsedwa kwathunthu .
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 zida zamagalimoto za MG&750 zolandiridwa kugula.
