Kodi ntchito ya sensa ya camshaft yamagalimoto ndi yotani?
Sensa ya malo a Camshaft imagwira ntchito yofunika kwambiri mu injini yagalimoto, ntchito yayikulu ndikusonkhanitsa chizindikiro cha malo a camshaft ndikuchiyika ku unit yowongolera zamagetsi (ECU) kuti idziwe nthawi yoyatsira ndi nthawi yolowetsa mafuta. Pozindikira malo ozungulira a camshaft, sensa imazindikira nthawi yotsegulira ndi kutseka kwa valavu, motero imapangitsa kuti injiniyo ilamulire bwino.
Mfundo yogwirira ntchito ya sensa ya camshaft imachokera pa ukadaulo wa electromagnetic induction kapena photoelectric induction. Pamene camshaft ikuzungulira, sensa imazindikira bump kapena notch mu camshaft ndikupanga chizindikiro chamagetsi chofanana. Pambuyo polandira zizindikirozi, ECU imazindikira nthawi yoyatsira ndi nthawi yoperekera mafuta kudzera mu kuwerengera ndi kukonza, kuti ikwaniritse kuwongolera kolondola kwa injini.
Kulondola ndi kudalirika kwa masensa okhala ndi camshaft ndikofunikira kwambiri pakugwira ntchito bwino kwa injini komanso kusunga mafuta. Ngati sensa yalephera, izi zingayambitse kuyaka kolakwika, kuchepa kwa mafuta, komanso mwina injini yomwe sigwira ntchito bwino. Chifukwa chake, kuyang'anira nthawi zonse ndi kukonza sensa yokhala ndi camshaft ndikofunikira kwambiri.
Sensor ya camshaft ndi gawo lofunika kwambiri la galimoto, lomwe limagwiritsidwa ntchito kwambiri kuzindikira malo a camshaft ndi liwiro lake, kuti litsimikizire kuti injini ikugwira ntchito bwino. Sensor ya Camshaft, yomwe imadziwikanso kuti Camshaft Position Sensor (CPS) kapena Cylinder Identification Sensor (CIS), ntchito yake yayikulu ndikusonkhanitsa zizindikiro za malo a camshaft ya valve. Zizindikirozi zimalowetsedwa mu electronic control Unit (ECU). Kuchokera ku zizindikiro izi, ECU imatha kuzindikira TDC ya compression ya silinda 1 kuti ilamulire mafuta motsatizana, kuwongolera nthawi yoyatsira moto ndi kuwongolera kutha kwa moto.
Kapangidwe ndi mfundo yogwirira ntchito
Pali mitundu yambiri ya masensa a camshaft position, kuphatikizapo photoelectric ndi magnetic induction. Photoelectric sensor imapangidwa makamaka ndi signal disk, signal generator ndi distributor, ndipo imapanga signal kudzera mu light-emitting diode ndi photosensitive transistor. Magnetic induction type imagwiritsa ntchito Hall effect kapena mfundo ya magnetic induction kuti ipange signals, zomwe nthawi zambiri zimagawidwa m'magulu a Hall type ndi magnetoelectric type .
Malo oyika
Sensa yoika camshaft nthawi zambiri imayikidwa kutsogolo kwa chivundikiro cha camshaft, moyang'anizana ndi kutsogolo kwa camshaft yolowera ndi yotulutsa mpweya. Kapangidwe kameneka kamatsimikizira kuti sensa imatha kusonkhanitsa molondola chizindikiro cha camshaft .
Kulephera ndi zotsatira zake
Ngati sensa ya camshaft yalephera, zizindikiro zodziwika bwino zimaphatikizapo kuvutika kuyambitsa galimoto, kuvutika kudzaza mafuta kapena kuyima ikatentha, kugwiritsa ntchito mafuta ambiri, mphamvu yosakwanira komanso kuthamanga pang'ono. Zizindikirozi zimachitika chifukwa cha kulephera kwa ECU kuwongolera molondola kulowetsa mafuta ndi nthawi yoyatsira moto.
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.
