paCamshaft position sensor - Chida chowonera.
Ntchito yayikulu ya camshaft position sensor ndi kusonkhanitsa chizindikiro cha Angle champhamvu cha camshaft ndikuchiyika ku gawo loyang'anira zamagetsi (ECU) kuti mudziwe nthawi yoyatsira ndi nthawi yobaya mafuta. Njirayi imaphatikizapo kuwongolera jekeseni wamafuta motsatizana, kuwongolera nthawi yoyatsira ndikuwongolera kuti injini igwire bwino ntchito. Kuphatikiza apo, sensa ya camshaft position imathanso kudziwa kuti silinda pisitoni iti ifike ku TDC, chifukwa chake imadziwikanso kuti sensa yozindikira silinda. Chizindikiro chake chimagwiritsidwanso ntchito kuzindikira nthawi yoyamba kuyatsa injini ikayamba, zomwe ndizofunikira kuti injini iyambe ndikuthamanga.
Mfundo yogwirira ntchito komanso kufunikira kwa sensa ya camshaft ikuwonetsedwa m'magawo awa:
Kupeza ndi kukonza kwa ma Signal : Sensa imasonkhanitsa ma signature ndi liwiro la camshaft ndikutumiza zidziwitso ku ECU, yomwe imayang'anira jakisoni wamafuta ndi nthawi yoyatsira molingana ndi ma siginowa kuti akwaniritse bwino ntchito ya injini.
Kuyatsa ndi kuwongolera jakisoni wamafuta : masensa a camshaft amathandizira ECU kudziwa nthawi yabwino yoyatsira ndi jekeseni wamafuta, zomwe ndizofunikira kwambiri pakuwongolera mafuta komanso kuchepetsa kutulutsa mpweya.
chiyambi kuzindikira : Pamene injini ikuyamba, camshaft position sensor imathandiza ECU kuzindikira nthawi yoyamba yoyatsira kuti injiniyo iyambe bwino.
Impact : Ngati sensa ya camshaft ikalephera, imatha kupangitsa kuti injini ichepe kapena kulephera kuyambitsa chifukwa ECU siyitha kuwongolera nthawi yoyaka ndi jekeseni wamafuta.
Mwachidule, camshaft udindo sensa ndi chigawo chachikulu mu dongosolo lamakono kulamulira injini galimoto, udindo wake osati kupereka poyatsira ndi jekeseni zizindikiro kulamulira mafuta, komanso zikuphatikizapo chiyambi chizindikiritso ndi ntchito zina, amene zimakhudza mwachindunji. pa ntchito yonse ndi chitetezo cha injini. pa
Kodi mawonekedwe a convex shaft sensor kulephera ndi chiyani?
Kuchita kwa kulephera kwa sensa ya camshaft kumaphatikizapo kulephera kuyamba, kuvutika poyambira, kuthamanga kosasunthika kosagwira ntchito, kufooka kwa injini, kuwonjezeka kwa mafuta, kugwedezeka kwa galimoto, kuwala kolephera kumapitirizabe kuyatsa, kutsekedwa kwadzidzidzi pamene galimoto yotentha, kuyendetsa galimoto, ndi zina zotero.
Zina zowonetsera zolakwika ndi zoyambitsa ndi izi:
1, kuyatsa kulephera: camshaft udindo sensa akhoza kudziwa zinayendera poyatsira, kulephera kuchititsa kulephera kuyatsa, pa nthawi ino injini si kophweka kuyamba;
2, injini palibe mphamvu: pamene camshaft udindo sensa akulephera, ECU sangathe kudziwa kusintha kwa camshaft udindo, kotero sangathe kuzindikira bwino malo kusintha kwa camshaft, zomwe zimakhudza kudya ndi utsi buku la pafupi utsi dongosolo. , ndiyeno zimakhudza magwiridwe a injini;
3, kuchuluka kwamafuta: pomwe sensa ya camshaft ikalephera, kompyuta imasokonekera jekeseni wamafuta, zomwe zimapangitsa kuti mafuta azigwiritsidwa ntchito, kufooka kwagalimoto, kuthamanga kwapang'onopang'ono;
4, galimoto yotentha mwadzidzidzi shutdown: udindo wa camshaft udindo sensa ndi wovuta kwambiri, ngati camshaft udindo sensa kulephera, ntchito injini adzakhala ndi zotsatira zina.
Galimotoyo ikakhala ndi zovuta zomwe zili pamwambapa, siziyenera kutengedwa mopepuka ndikupita kumalo okonzera akatswiri kuti akawunike mwachangu.
Ngati mukufuna kudziwa zambiri, pitilizani kuwerenga zolemba zina patsamba lino!
Chonde tiyimbireni ngati mukufuna zinthu zotere.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zolandiridwa kuti mugule.
