Kodi gudumu la chizindikiro cha crankshaft yagalimoto ndi chiyani?
Gudumu la chizindikiro cha crankshaft yagalimoto , lomwe limadziwikanso kuti crankshaft position sensor kapena injini speed sensor, ntchito yake yayikulu ndikuwunika liwiro la crankshaft ndi ngodya ya injini, kuti adziwe bwino malo a crankshaft. Deta yosonkhanitsidwa imatumizidwa ku Engine Control Unit (ECU) kapena makompyuta ena oyenera kuti atsimikizire kuti nthawi yoyatsira injini ikuyendetsedwa bwino.
Mfundo yogwirira ntchito
Gudumu la chizindikiro cha crankshaft nthawi zambiri limapangidwa ngati gudumu lokhala ndi magawo angapo a mano. Gudumu la chizindikiro likadutsa mu sensa, magetsi a AC amapangidwa, ndipo kuchuluka kwa magetsi amenewa kumasintha malinga ndi kusintha kwa liwiro. Kapangidwe kameneka kamalola sensa kuyeza liwiro la injini pogwiritsa ntchito chizindikiro cha pulse.
Mtundu ndi malo okhazikitsa
Gudumu la chizindikiro cha crankshaft malinga ndi mfundo yopangira zizindikiro lingagawidwe m'magulu awiri: mtundu wa maginito induction, mtundu wa photoelectric ndi mtundu wa Hall. Masensa a Common Hall nthawi zambiri amagwiritsa ntchito kapangidwe ka mawaya atatu, kuphatikiza chingwe chamagetsi, chingwe cha chizindikiro cha AC ndi chingwe choteteza chizindikiro cha AC. Malo oyika nthawi zambiri amakhala mu chogawa, pa nyumba yolumikizira ma transmission clutch, kutsogolo kapena kumbuyo kwa crankshaft, ndi zina zotero, kutengera mtundu wa sensa ndi kapangidwe ka injini.
Gwirani ntchito limodzi ndi zigawo zina
Gudumu la chizindikiro cha crankshaft nthawi zambiri limagwira ntchito limodzi ndi sensa ya malo a camshaft kuti lidziwe nthawi yoyambira yoyatsira. Mwa kupereka chidziwitso cholondola cha malo, amaonetsetsa kuti injiniyo ikhoza kugwira ntchito motsatira ndondomeko yoyatsira yomwe idakonzedweratu, motero imagwira ntchito bwino komanso mosalala.
Ntchito yaikulu ya gudumu la chizindikiro cha crankshaft ya galimoto ndi kuzindikira liwiro la crankshaft ndi ngodya ya injini, kudziwa malo a crankshaft, ndi kutumiza zotsatira zomwe zapezeka ku unit yowongolera injini (ECU) kapena makina ena apakompyuta kuti zitsimikizire kuwongolera kolondola kwa nthawi yoyatsira injini .
Makamaka, gudumu la chizindikiro cha crankshaft (lomwe limadziwikanso kuti sensor ya malo a crankshaft kapena sensor ya liwiro la injini) lili ndi ntchito zotsatirazi:
Yang'anani liwiro la injini: Dziwani momwe injini ikuyendera pozindikira liwiro la crankshaft.
Dziwani malo a pistoni TDC : Dziwani malo a TDC a pistoni iliyonse ya silinda. Izi ndizofunikira kwambiri powongolera kuyatsa ndi nthawi yopangira mafuta. Mwachitsanzo, imatha kupereka zizindikiro za TDC za silinda imodzi imodzi zowongolera kuyatsa ndi zizindikiro za TDC za silinda yoyamba zowongolera kuyatsa mafuta motsatizana .
Imapereka chizindikiro cha ngodya ya crankshaft: Pozindikira ngodya ya crankshaft, onetsetsani kuti nthawi yoyatsira injini ndi nthawi yoyikira mafuta ndi yolondola.
Imagwira ntchito ndi sensa ya malo a camshaft : Nthawi zambiri imagwira ntchito ndi sensa ya malo a camshaft kuti iwonetsetse kuti nthawi yoyatsira ya injini ndi yolondola. Sensa ya malo a camshaft imatsimikiza kuti ndi pistoni iti ya silinda yomwe ili pa compression stroke, pomwe sensa ya malo a crankshaft imatsimikiza kuti ndi pistoni iti ya silinda yomwe ili pa TDC .
Kuphatikiza apo, mawonekedwe a gudumu la chizindikiro cha crankshaft akuphatikizapo gudumu lokhala ndi magawo angapo a mano. Gudumu la chizindikiro likadutsa mu sensa, magetsi a AC amapangidwa omwe ma frequency ake amasinthasintha malinga ndi liwiro .
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
