Kodi gudumu la chizindikiro cha automobile crankshaft ndi chiyani
Galimoto ya crankshaft signal wheel, yomwe imadziwikanso kuti crankshaft position sensor kapena injini yothamanga, ntchito yake yaikulu ndikuwunika kuthamanga kwa crankshaft ndi Angle ya injini, kuti mudziwe bwino malo a crankshaft. Zomwe zasonkhanitsidwa zimatumizidwa ku Engine Control Unit (ECU) kapena makina ena apakompyuta kuti atsimikizire kuwongolera kolondola kwa nthawi yoyatsira injini.
Mfundo yogwira ntchito
Whewelo la chizindikiro cha crankshaft nthawi zambiri limapangidwa ngati gudumu lomwe lili ndi zigawo zingapo zamano. Pamene gudumu la chizindikiro likudutsa mu sensa, magetsi a AC amapangidwa, ndipo mafupipafupi a magetsiwa amasinthasintha ndi kusintha kwa liwiro. Kapangidwe kameneka kamalola kachipangizo kameneka kuyeza liwiro la injiniyo pogwiritsa ntchito chizindikiro cha kugunda kwa mtima.
Lembani ndi kuika malo
Wheel yolumikizira crankshaft molingana ndi mfundo yopangira ma siginecha imatha kugawidwa mumtundu wa maginito opangira maginito, mtundu wazithunzi ndi mtundu wa Hall mitundu itatu. Masensa a Common Hall nthawi zambiri amatenga mawonekedwe a mawaya atatu, kuphatikiza chingwe chamagetsi, chingwe cha siginecha ya AC ndi chingwe chotchingira chizindikiro cha AC. Malo oyikapo nthawi zambiri amakhala mu distributor, pa nyumba yotumizira ma clutch, kutsogolo kapena kumbuyo kwa crankshaft, etc., kutengera mtundu wa sensa ndi injini.
Gwirani ntchito limodzi ndi zigawo zina
Wheel ya crankshaft siginecha nthawi zambiri imagwira ntchito limodzi ndi camshaft position sensor kuti idziwe nthawi yoyambira kuyatsa. Popereka chidziwitso cholondola cha malo, amawonetsetsa kuti injiniyo imatha kugwira ntchito motsatana ndi kuwombera komwe idakonzedweratu, motero imagwira ntchito bwino komanso moyenera.
Ntchito yayikulu ya gudumu lamagetsi la crankshaft ndikuzindikira kuthamanga kwa crankshaft ndi Ngongole ya injini, kudziwa malo a crankshaft, ndikutumiza zotsatira zomwe zapezeka kugawo lowongolera injini (ECU) kapena makina ena apakompyuta kuti atsimikizire kuwongolera kolondola kwa nthawi yoyatsira injini.
Makamaka, gudumu la siginecha ya crankshaft (yomwe imadziwikanso kuti crankshaft position sensor kapena sensor speed sensor) ili ndi izi:
Yang'anani liwiro la injini : Dziwani momwe injini ikugwirira ntchito pozindikira kuthamanga kwa crankshaft.
Dziwani malo a pisitoni a TDC: Dziwani malo a TDC pa silinda ya silinda iliyonse. Izi ndizofunikira pakuwongolera kuyatsa ndi nthawi yobaya mafuta. Mwachitsanzo, imatha kupereka ma silinda amtundu wa TDC wowongolera kuyatsa ndi ma silinda a TDC oyamba kuti athe kuwongolera jakisoni wotsatizana wamafuta.
imapereka chizindikiro cha crankshaft Angle : Pozindikira mbali ya crankshaft, onetsetsani kuti injini yoyatsira komanso nthawi yojambulira mafuta ndiyolondola.
imagwira ntchito ndi camshaft position sensor : Nthawi zambiri imagwira ntchito ndi camshaft position sensor kuti iwonetsetse kuti nthawi yoyatsira injini ndi yolondola. Chojambulira cha camshaft chimazindikira kuti pistoni ya silinda iti yomwe ili pachiwopsezo, pomwe sensa ya crankshaft imazindikira pistoni ya silinda yomwe ili pa TDC.
Kuphatikiza apo, mawonekedwe a gudumu la chizindikiro cha crankshaft amaphatikizanso gudumu lomwe lili ndi zigawo zingapo zamano. Pamene gudumu la chizindikiro likudutsa mu sensa, magetsi a AC amapangidwa omwe ma frequency amasinthasintha ndi liwiro.
paNgati mukufuna kudziwa zambiri, pitilizani kuwerenga zolemba zina patsamba lino!
